  • Mouse move panning

    - by Rudy
    Hi all, I'm trying to scroll a series of thumbnails horizontally based on the mouseX position. I can get it to scroll but it's very choppy and for some reason it's not reading my start and end numbers so it will stop scrolling. Can anyone point me in the right direction? Thanks. var thumbBounds:Object = new Object(); thumbBounds = thumbContainer.getBounds(this); thumbContainer.addEventListener(MouseEvent.MOUSE_OVER, setScrolling); private function setScrolling(me:MouseEvent):void { thumbContainer.removeEventListener(MouseEvent.MOUSE_OVER, setScrolling); stage.addEventListener(Event.ENTER_FRAME, scrollThumbs); } private function scrollThumbs(e:Event):void { if(mouseX <= thumbBounds.x || mouseX thumbBounds.width || mouseX < thumbBounds.y || mouseX thumbBounds.height) { thumbContainer.addEventListener(MouseEvent.MOUSE_OVER, setScrolling); stage.removeEventListener(Event.ENTER_FRAME, scrollThumbs); } if(thumbContainer.x = 0) { thumbContainer.x = 0; } if(thumbContainer.x <= -842) { thumbContainer.x = -842; } var xdist:Number = new Number(); xdist = mouseX - 382; thumbContainer.x += Math.round(-xdist / 10); }

  • [iPhone] UIScrollView notifications

    - by ryyst
    Hi, I'm coding an app that works much like Apple's Weather.app: There's a UIPageControl at the bottom and a UIScrollView in the middle of the screen. In my code, I implemented the - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView method to figure out when the user did move to a new page. If they move to a new page, I load the adjacent pages' data, as to make further page-switching faster. (In one of Apple's examples, the - (void)scrollViewDidScroll:(UIScrollView *)sender is used, but that causes my app to shortly hang when loading a new page, so it's not suitable.) That code works very well. I'm using scrollRectToVisible:: to programmatically scroll inside the scrollview when the user clicks the UIPageControl. The problem is that the scrollRectToVisible: doesn't post a notification to the UIScrollViewDelegate when it's done scrolling - so the code responsible for loading adjacent pages never get's called when using the UIPageControl. Is there any way to make the UIScrollView notify its delegate when it gets called by the scrollRectToVisible: method? Or will I have to use threads in order to prevent my app from freezing? Thanks! -- Ry

  • Position Div using Javascript on page refresh

    - by Jonathan Lyon
    Hi all I have a div that I would like to reposition each time the page is refreshed. It is currently set in the css using top and left. I wold like to pass the top and left values on page refresh. #inneriframe { position:absolute; top:-170px; left:-5px; width:1280px; height:1200px; } The content is from another site and contained in an iframe and I want the viewport of the div to change(within certain limits) each time the page is refreshed. The original page is here http://labs.ideeinc.com/multicolr#colors=8438AD; I have iFramed part of it here http://www.weninja.com/what-we-do Full code <style type="text/css"> #outerdiv { width:280px; height:150px; overflow:hidden; position:relative; } #inneriframe { position:absolute; top:-170px; left:-5px; width:1280px; height:1200px; } </style> <div id='outerdiv'> <iframe src="http://labs.ideeinc.com/multicolr#colors=8438AD;" id='inneriframe' scrolling=no></iframe> </div> <h5>Multicolr Search Lab &copy; 2008 Idee Inc</h5> So basically I just need to change the TOP and LEFT values for the div #inneriframe to have different images show - is this possible? Thanks Jonathan

  • iPad: Detecting External Keyboard

    - by StuartW
    My app uses a UIAccessoryView to provide additional keyboard functionality (such as forward/backward tabs and arrows keys) for the virtual keyboard, but that causes UIKeyboardDidShowNotification to fire even when a physical keyboard is present (the accessory appears at the bottom of the screen). I'd like to check if a physical keyboard is attached when handling UIKeyboardWillShowNotification, to prevent the accessory view from appearing and to prevent my custom view from scrolling up (to make room for the non-existent virtual keyboard). I've tried examining the UIKeyboardFrameEndUserInfoKey key, but it returns a real size for the virtual keyboard, in spite of nothing being displayed. Is there any way to detect the presence of a physical keyboard to prevent this unwanted behaviour? Hmm, the plot thickens. I tried disabling the input accessory by returning nil from the inputAccessoryView property of the Responder object which triggers the keyboard. That suppresses UIKeyboardWillShowNotification and UIKeyboardDidShowNotification when there is a physical keyboard present, but keeps these notifications when there is no such keyboard. All good so far. Then I tried re-enabling inputAccessoryView only after UIKeyboardWillShowNotification had been received. This only fires when a virtual keyboard is needed, so it should allow me to reintroduce the accessory view in those circumstances. Or so I thought. Unfortunately, it seems the OS doesn't check inputAccessoryView after UIKeyboardWillShowNotification, so it fails to show the accessory view when it is needed :o( That leaves me with two options: Include the input accessory view, giving extra functionality for virtual keyboard users, but lose the ability to detect a physical keyboard and hence not supporting physical devices; or Exclude the input accessory altogether, preventing most users from accessing the extra keys, but allowing the app to work with a physical keyboard. Not a great choice, so I'm still keen to see if anyone else has addressed this problem!

  • Using a UITableViewController with a small-sized table?

    - by rpj
    When using a UITableViewController, the initWithStyle: method automatically creates the underlying UITableView with - according to the documentation - "the correct dimensions". My problem is that these "correct dimensions" seem 320x460 (the iPhone's screen size), but I'm pushing this TableView/Controller pair into a UINavigationController which is itself contained in a UIView, which itself is about half the height of the screen. No frame or bounds wrangling I can come up with seems to correctly reset the table's size, and as such it's "too long", meaning there are a collection of rows that are pushed off the bottom of the screen and are not visible nor reachable by scrolling. So my question comes down to: what is the proper way to tell a UITableViewController to resize its component UITableView to a specified rectangle? Thanks! Update I've tried all the techniques suggested here to no avail, but I did find one interesting thing: if I eschew the UINavigationController altogether (which I'm not yet willing to do for production, but as an experiment), and add the table view as a direct subview of the enclosing view I mentioned, the frame size given is respected. The very moment I re-introduce the UINavigationController into the mix, no matter if it is added as a subview before or after the table view, and no matter if alloc/init it before or after the table view is added as a subview, the result is the same as it was before. I'm beginning to suspect UINavigationController isn't much of a team player... Update 2 The suggestion to check frame size after the table view on screen was a good one: turns out that the navigation controller is in fact resizing it some time in between load and display. My solution, hacky at best, has been to cache the frame given on load and to reset it if changed at the beginning of tableView:cellForRowAtIndexPath:. Why there you ask? Because it's the one place I found that worked, that's why! I don't consider this a solution as it's obviously improper, but for the benefit of anyone else reading, it does seem to work.

  • TinyMce imagemanager won't generate image path when used with an iframe

    - by Tom
    I have successfully setup tinymce to work on a page within an iframe. Everything works perfectly. However, when you use imagemanager to pick an image to be inserted or replaced in the editor it will not copy the path(and filename) of the image to the "Image URL" input in the "Insert/edit image" box. The box will either remain empty or keep the address of the previous image. The behaviour is the same with the filemanager plugin. tinyMCE.init( { mode : "none", editor_selector : "mceEditor", theme : "advanced", plugins : "filemanager,imagemanager,autoresize,safari,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template,inlinepopups,spellchecker", theme_advanced_buttons1 : "insertfile,insertimage,advimage,imagemanager,bold,italic,underline,|,justifyleft,justifycenter,justifyright,justifyfull,nonbreaking,cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist", theme_advanced_buttons2 : "blockquote,|,link,unlink,anchor,image,cleanup,help,code,|,insertdate,inserttime,|,forecolor,backcolor,|,charmap,iespell,media,advhr", theme_advanced_layout_manager : "SimpleLayout", theme_advanced_buttons3 : "tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,strikethrough", theme_advanced_buttons4 : "styleselect,formatselect,fontselect,fontsizeselect,|,undo,redo,|,spellchecker", theme_advanced_toolbar_location : "external", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "bottom", relative_urls : true, document_base_url : "http://devtom.ecitb.org.uk/", auto_resize : true, content_css : "/custom/css/style.css", extended_valid_elements : "iframe[height|width|src|frameborder|scrolling]", }); /* The following code comes from- http://tinymce.moxiecode.com/punbb/viewtopic.php?id=12966 Without it the editor only loads 10% of the time.

The other changes mentioned in the post have also been implemented. */ var setupTiny = function() { var ifrObj = document.getElementById('pageEditIFrame'); var win = ifrObj; if (win.contentWindow) { win = win.contentWindow; } var d; if(ifrObj.contentDocument) { d = ifrObj.contentDocument; } else if (ifrObj.contentWindow) { d = ifrObj.contentWindow.document; } else if (ifrObj.document) { d = ifrObj.document; } textAreas.each(function(txtEl) { tinyMCE.execCommand('mceAddFrameControl', false, { element_id : txtEl, window : win, doc : d }); }); }; //Waiting 1 second seems to make the editor load more reliably. setTimeout("setupTiny();",1000);

  • Increase width of divs, displayed side by side, using draggable events

    - by Vaibhav Shukla
    I have two divs of fixed length as of now, which loads external URL by dynamically embedding iframes inside them. Divs are appearing next to each other - one on left and other right. As of now, I have fixed their width to 50% each. But, I want to give user a flexibility to increase the width of any div to view the URL inside easily without scrolling horizontally. Something like dragging the border separating the two divs to either left or right according to his need. Is there a way I could achieve this? Please suggest any library or something. I have gone through a library twentytwenty which is used for images. I don't know how will that work for dynamic iframes. Here is the JSFiddle which displays the divs. <div> <div id="originalPage" style="width:54%;height: 730px;float:left"> <p>one div </p> </div> <div id="diffReport" style="width:45%; height: 730px;float:right"> <p>another div</p> </div> </div>

  • Implementing scroll view that is much larger than the screen view with random images

    - by pulegium
    What I'm trying to do is to implement something like the fruit machine scroll view. Basically I have a sequence of images (randomly generated on the fly) and I want to allow the users to scroll through this line. There can fit approx 10 images on the screen, but the line is virtually unlimited. My question is what would be the best approach in implementing this? So far I've thought of having a UIImageView going across the screen (with width equal to the sum of 10 images) and the image associated with it would be a combination of 12 or so images, with two images falling out of the visible area, this would allow for smooth scrolling. If the user scrolls further, then I would reconstruct the image associated with the view so the new images are appended and the old one's are discarded. This image reconstruction business sounds bit complicated, so I was wondering if there's a more logical way to implement this. There's one more thing, I want to have two lines crossing each other with images, bit like conveyor belts crossing. If that makes any sense... Bit like below: V1 V2 H1 H2 H3 H4 H5 V4 V5 So if the vertical belt is moved it'd be like: V2 H3 H1 H2 V4 H4 H5 V5 V6 H1-H5, V1-V6 being automatically generated images. I'm not asking for the implementation code, just the thoughts on the principles how to implement this. Thanks!! :)

  • UITableViewCell imageView images loading small even when they are the correct size!

    - by Alex Barlow
    Im having an issue whilst loading images into a UITableViewCell after an asynchronous download and placement into an UIImage variable.. The images appear smaller than they actually are! But when scrolled down and scrolled back up to the image, or the whole table is reloaded, they appear at the correct size... Here is a code excerpt... - (void)reviewImageDidLoad:(NSIndexPath *)indexPath { ThumbDownloader *thumbDownloader = [imageDownloadsInProgress objectForKey:indexPath]; if (thumbDownloader != nil) { UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:thumbDownloader.indexPathInTableView]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.4]; [self.tableView cellForRowAtIndexPath:indexPath].imageView.alpha = 0.0; [UIView commitAnimations]; cell.imageView.image = thumbDownloader.review.thumb; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.4]; [self.tableView cellForRowAtIndexPath:indexPath].imageView.alpha = 1.0; [UIView commitAnimations]; } } Here is an image of the app just after calling this method.. http://www.flickr.com/photos/arbarlow/5288563627/ After calling tableView reloadData or scrolling around the appear correctly, go the the next flickr image, to see the normal result, but im sure you can guess that.. Does anyone have an ideas as to make the images appear correctly? im absolutely stumped?! Regards, Alex iPhone noob

  • Does android maps support ground overlay?

    - by wmh1108
    I have a weather image I would like to use as an overlay in the google maps android api. I would like to achieve the same result that I get from using GroundOverlay in KML files, such as <GroundOverlay> <name>myimage</name> <Icon> <href>myimage.png</href> <viewBoundScale>0.75</viewBoundScale> </Icon> <LatLonBox> <north>75.6088</north> <south>5.0121</south> <east>182.2805</east> <west>120.6795</west> </LatLonBox> </GroundOverlay> The above will ensure that the 4 corners of my image stay anchored to the 4 lat/long points listed, regardless of scrolling, zooming etc.. Is there a way to accomplish this using the google api/maps provided for android?

    Hello, I have a class containing Enum with values. (names) In other class I would like to enter inside a table a cell type of JCombobox that will use these enums values. my problem is to combain between string values and the enum. for example the enum class: enum item_Type {entree, main_Meal, Dessert, Drink} for example the table class: setTitle("Add new item" ); setSize(300, 80); setBackground( Color.gray ); // Create a panel to hold all other components topPanel = new JPanel(); topPanel.setLayout( new BorderLayout() ); getContentPane().add( topPanel ); //new JComboBox(item_Type.values()); JComboBox aaa = new JComboBox(); aaa = new JComboBox(item_Type.values()); TableColumn sportColumn = table.getColumnModel().getColumn(2); // Create columns names String columnNames[] = {"Item Description", "Item Type", "Item Price"}; // Create some data String dataValues[][] = {{ "0", aaa, "0" }}; // Create a new table instance table = new JTable( dataValues, columnNames ); // Add the table to a scrolling pane scrollPane = new JScrollPane( table ); topPanel.add( scrollPane, BorderLayout.CENTER ); I know that at the dataValues array I cant use aaa (the enum jcombobox). How can I do that? thanks in advance.

  • while I scroll between the layout it takes too long to be able to scroll between the gallerie's pictures. Is there any way to reduce this time?

    - by Mateo
    Hello, this is my first question here, though I've being reading this forum for quite a while. Most of the answers to my doubts are from here :) Getting back on topic. I'm developing an Android application. I'm drawing a dynamic layout that are basically Galleries, inside a LinearLayout, inside a ScrollView, inside a RelativeLayout. The ScrollView is a must, because I'm drawing a dynamic amount of galleries that most probably will not fit on the screen. When I scroll inside the layout, I have to wait 3/4 seconds until the ScrollView "deactivates" to be able to scroll inside the galleries. What I want to do is to reduce this time to a minimum. Preferably I would like to be able to scroll inside the galleries as soon as I lift my finger from the screen, though anything lower than 2 seconds would be great as well. I've being googling around for a solution but all I could find until now where layout tutorials that didn't tackle this particular issue. I was hoping someone here knows if this is possible and if so to give me some hints on how to do so. I would prefer not to do my own ScrollView to solve this. But if that is the only way I would appreciate some help because I'm not really sure how would I solve this issue by doing that. this is my layout: public class PicturesL extends Activity implements OnClickListener, OnItemClickListener, OnItemLongClickListener { private ArrayList<ImageView> imageView = new ArrayList<ImageView>(); private StringBuilder PicsDate = new StringBuilder(); private CaWaApplication application; private long ListID; private ArrayList<Gallery> gallery = new ArrayList<Gallery>(); private ArrayList<Bitmap> Thumbails = new ArrayList<Bitmap>(); private String idioma; private ArrayList<Long> Days = new ArrayList<Long>(); private long oldDay; private long oldThumbsLoaded; private ArrayList<Long> ThumbailsDays = new ArrayList<Long>(); private ArrayList<ArrayList<Long>> IDs = new ArrayList<ArrayList<Long>>(); @Override public void onCreate(Bundle savedInstancedState) { super.onCreate(savedInstancedState); RelativeLayout layout = new RelativeLayout(this); ScrollView scroll = new ScrollView(this); LinearLayout realLayout = new LinearLayout(this); ArrayList<TextView> texts = new ArrayList<TextView>(); Button TakePic = new Button(this); idioma = com.mateloft.cawa.prefs.getLang(this); if (idioma.equals("en")) { TakePic.setText("Take Picture"); } else if (idioma.equals("es")) { TakePic.setText("Sacar Foto"); } RelativeLayout.LayoutParams scrollLP = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.FILL_PARENT); layout.addView(scroll, scrollLP); realLayout.setOrientation(LinearLayout.VERTICAL); realLayout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); scroll.addView(realLayout); TakePic.setId(67); TakePic.setOnClickListener(this); application = (CaWaApplication) getApplication(); ListID = getIntent().getExtras().getLong("listid"); getAllThumbailsOfID(); LinearLayout.LayoutParams TakeLP = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); realLayout.addView(TakePic); oldThumbsLoaded = 0; int galler = 100; for (int z = 0; z < Days.size(); z++) { ThumbailsManager croppedThumbs = new ThumbailsManager(Thumbails, oldThumbsLoaded, ThumbailsDays.get(z)); oldThumbsLoaded = ThumbailsDays.get(z); texts.add(new TextView(this)); texts.get(z).setText("Day " + Days.get(z).toString()); gallery.add(new Gallery(this)); gallery.get(z).setAdapter(new ImageAdapter(this, croppedThumbs.getGallery(), 250, 175, true, ListID)); gallery.get(z).setOnItemClickListener(this); gallery.get(z).setOnItemLongClickListener(this); gallery.get(z).setId(galler); galler++; realLayout.addView(texts.get(z)); realLayout.addView(gallery.get(z)); } Log.d("PicturesL", "ListID: " + ListID); setContentView(layout); } private void getAllThumbailsOfID() { ArrayList<ModelPics> Pictures = new ArrayList<ModelPics>(); ArrayList<String> ThumbailsPath = new ArrayList<String>(); Pictures = application.dataManager.selectAllPics(); long thumbpathloaded = 0; int currentID = 0; for (int x = 0; x < Pictures.size(); x++) { if (Pictures.get(x).walkname == ListID) { if (Days.size() == 0) { Days.add(Pictures.get(x).day); oldDay = Pictures.get(x).day; IDs.add(new ArrayList<Long>()); currentID = 0; } if (oldDay != Pictures.get(x).day) { oldDay = Pictures.get(x).day; ThumbailsDays.add(thumbpathloaded); Days.add(Pictures.get(x).day); IDs.add(new ArrayList<Long>()); currentID++; } StringBuilder tpath = new StringBuilder(); tpath.append(Pictures.get(x).path.substring(0, Pictures.get(x).path.length() - 4)); tpath.append("-t.jpg"); IDs.get(currentID).add(Pictures.get(x).id); ThumbailsPath.add(tpath.toString()); thumbpathloaded++; if (x == Pictures.size() - 1) { Log.d("PicturesL", "El ultimo de los arrays, tamaño: " + Days.size()); ThumbailsDays.add(thumbpathloaded); } } } for (int y = 0; y < ThumbailsPath.size(); y++) { Thumbails.add(BitmapFactory.decodeFile(ThumbailsPath.get(y))); } } I had a memory leak on another activity when screen orientation changed that was making it slower, now it is working better. The scroller is not locking up. But sometimes, when it stops scrolling, it takes a few seconds (2/3) to disable itself. I just want it to be a little more dynamic, is there any way to override the listener and make it stop scrolling ON_ACTION_UP or something like that? I don't want to use the listview because I want to have each gallery separated by other views, now I just have text, but I will probably separate them with images with a different size than the galleries. I'm not really sure if this is possible with a listadapter and a listview, I assumed that a view can only handle only one type of object, so I'm using a scrollview of a layout, if I'm wrong please correct me :) Also this activity works as a preview or selecting the pictures you want to view in full size and manage their values. So its working only with thumbnails. Each one weights 40 kb. Guessing that is very unlikely that a user gets more than 1000~1500 pictures in this view, i thought that the activity wouldn't use more than 40~50 mb of ram in this case, adding 10 more if I open the fullsized view. So I guessed as well most devices are able to display this view in full size. If it doesn't work on low-end devices my plan was to add an option in the app preferences to let user chop this view according to some database values. And a last reason is that during most of this activity "life-cycle" (the app has pics that are relevant to the view, when it ends the value that selects which pictures are displayed has to change and no more pictures are added inside this instance of this activity); the view will be unpopulated, so most of the time showing everything wont cost much, just at the end of its cycle That was more or less what I thought at the time i created this layout. I'm open to any sort of suggestion or opinion, I just created this layout a few days ago and I'm trying to see if it can work right, because it suits my app needs. Though if there is a better way i would love to hear it Thanks Mateo

  • Is there a way to stop a UIViewController from being popped from a UINavigationController's stack wh

    - by yabada
    I have a UINavigationController with a root view controller and then I push a UIViewController onto the navigation controller's stack. When the user taps the backBarButtonItem I'd like to be able to have an alert view pop up if there are certain conditions met and cancel the pop of the view controller. For example, the user can make certain selections but some combination of them may be invalid so I want to notify them to make changes. I know that I can prevent the user from making an invalid combination or have an alert view pop up when the invalid combination is selected but I'd rather not do that. The user may be changing selections and may be aware that a certain combination is invalid but I'd rather let them select something that makes the combination invalid then go change something else (and notify them if they haven't made changes before trying to go to the previous screen). For example, if I prevent them from make the invalid combination then they may have to scroll up on a screen, change something, then scroll back down instead of making a selection then scrolling up and changing something. Using viewWillDisappear: doesn't work because, although I can produce an alert view, I cannot figure out a way to prevent the pop from occurring. The alert view pops up but the view controller still pops and they are back to the root view controller (with the alert view displaying). Is there a way to prevent the pop from occurring? If not, is this something worth filing a bug report about or is this unnecessary and/or esoteric?

  • HTML + CSS: fixed background image and body width/min-width (including fiddle)

    - by insertusernamehere
    So, here is my problem. I'm kinda stuck at the moment. I have a huge background image and content in the middle with those attributes: content is centered with margin auto and has a fixed width the content is related to the image (like the image is continued within the content) this relation is only horizontally (vertically scrolling moves everything around) This works actually fine (I'm only talking desktop, not mobile here :) ) with a position fixed on the huge background image. The problem that occurs is the following: When I resize the window to "smaller than the content" the background image gets it width from the body instead of the viewport. So the relation between content and image gets lost. Now I have this little JavaScript which does the trick, but this is of course some overhead I want to avoid: $(window).resize(function(){ img.css('left', (body.width() - img.width()) / 2 ); }); This works with a fixed positioned image, but can get a litty jumpy while calculating. I also tried things like that: <div id="test" style=" position: absolute; z-index: 0; top: 0; left: 0; width: 100%: height: 100%; background: transparent url(content/dummy/brand_backgroud_1600_1.jpg) no-repeat fixed center top; "></div> But this gets me back to my problem described. Is there any "script-less", elegant solution for this problem? UPDATE: now with Fiddle The one I'm trying to solve: http://jsfiddle.net/insertusernamehere/wPmrm/ The one with Javascript that works: http://jsfiddle.net/insertusernamehere/j5E8z/ NOTE The image size is always fixed. The image never gets scaled by the browser. In the JavaScript example it get's blown. So don't care about the size.

  • WPF create a list of controls that can be scrolled via the mouse but still remain functional

    - by Mark
    I have a list of controls that I am displaying via a WrapPanel and it horizontally oriented. I have implemented a "Click and Drag" scrolling technique so that the user scrolls with the mouse via clicking and dragging. Like so: <Canvas x:Name="ParentCanvas" PreviewMouseDown="Canvas_MouseDown" MouseMove="Canvas_MouseMove"> <WrapPanel> <WrapPanel.RenderTransform> <TranslateTransform /> </WrapPanel.RenderTransform> <!-- controls are all in here ... --> </WrapPanel> </Canvas> Then in the code behind: private Point _mousePosition; private Point _lastMousePosition; private void Canvas_MouseDown(object sender, MouseButtonEventArgs e) { _lastMousePosition = e.GetPosition(ParentCanvas); e.Handled = true; } private void Canvas_MouseMove(object sender, MouseEventArgs e) { _mousePosition = e.GetPosition(ParentCanvas); var delta = _mousePosition - _lastMousePosition; if(e.LeftButton == MouseButtonState.Pressed && delta.X != 0) { var transform = ((TranslateTransform)_wrapPanel.RenderTransform).Clone(); transform.X += delta.X; _wrapPanel.RenderTransform = transform; _lastMousePosition = _mousePosition; } } This all works fine But what I want to do is make it so that when a users clicks to drag, the items within the WrapPanel dont respond (i.e. the user is only browsing), but when the user clicks (as in a full click) then they do respond to the click. Just like how the iphone works, when you press and drag directly on an app, it does not open the app, but rather scrolls the screen, but when you tap the app, it starts... I hope this makes sense. Cheers, Mark

  • Faking Fixed Position in IE6

    I have a site that utilizes a bottom fixed position masthead here: http://www.entheospartners.com/newsite/ This setup works great in all browsers except IE6, which doesn't support fixed positioning in the least, so here's what I've done: When an IE6 user comes to the page, I make the determination if scrolling is necessary using this bit of code: var windowHeight = $(window).height(); var totalHeight = windowHeight - 100; // where 100 is the sum of the top nav height + footer height var contentHeight; if($('#subpage-content-small').length) { // main content div for a three column layout contentHeight = $('#subpage-content-small').height(); }; if($('#subpage-content-wide').length) { // main content div for a two column layout contentHeight = $('#subpage-content-wide').height(); }; if(contentHeight > totalHeight) { $('#container-container').css({ 'overflow-y' : "scroll", 'height' : totalHeight }); }; ...which calculates everything correctly, puts the scrollbars where they need to be (flush right), and sets them to the appropriate height. The problem is that the scrollbars don't move the content. I can't say that I've ever seen anything quite like this before, so I'm hoping someone else on here has. Thanks in advance! PS - Obviously, this needs to be looked at in IE6 for troubleshooting, which I know will be as painful for you as it is for me.

  • Animating translation and scaling of view in Android

    - by hgpc
    I have to animate a view from state A to B with changes to its scale, position and scrolling. I know everything about state A (widthA, heightA, topA, leftA, scrollXA, scrollYA) and state B (widthB, heightB, topB, leftB, scrollXB, scrollYB). So far I wrote the following code: AnimationSet animation = new AnimationSet(true); int toXDelta; // What goes here? int toYDelta; // What goes here? TranslateAnimation translateAnimation = new TranslateAnimation(1, toXDelta, 1, toYDelta); translateAnimation.setDuration(duration); animation.addAnimation(translateAnimation); float scale = (float) widthB / (float) widthA; ScaleAnimation scaleAnimation = new ScaleAnimation(1, scale, 1, scale); scaleAnimation.setDuration(duration); animation.addAnimation(scaleAnimation); animation.setAnimationListener(new AnimationListener() { @Override public void onAnimationEnd(Animation arg0) { view.clearAnimation(); // Change view to state B } @Override public void onAnimationRepeat(Animation arg0) {} @Override public void onAnimationStart(Animation arg0) {} }); view.startAnimation(animation); Is this the right way to do this? If so, how should I calculate the values of toXDelta and toYDelta? I'm having trouble finding the exact formula. Thanks!

  • Canvas scroll animation not working correctly

    - by pedalpete
    I'm building a gantt chart style timeline using html canvas element. I am currently attempting to add the functionality which allows the user to click a next/prev button to have the gantt chart scroll to display earlier or later times. The way I am doing this is to have a span.adjustTime where the id holds a value in seconds for the time to be adjusted (eg 86400 for one day). I am trying to animate the scrolling so it looks like a scroll, rather than jumping ahead by one day. I have a small problem in my timing calculation, but the script below is not animating, but rather jumping directly to the final time. I do have the draw function running on a separate setInterval which updates every second, so I'm hoping it isn't an issue of conflicting timers on the same function on the same element and data. jQuery('span.adjustTime').click(function() { var adjustBy = parseInt(jQuery(this).attr('id').replace('a', '')); var data = jQuery('img#logo').data(); for(var m = 1; m >= 30; m++) { gantt.startUnixTime = gantt.startUnixTime + (adjustBy * (m * 0.001)); var moveTimer = setTimeout(function() { draw(document.getElementById('gantt'), data, gantt); }, 1000); if (m == 30) { clearTimeout(moveTimer); } } });

  • Can Content script set value of a text box within HTML frame? using Google Chrome extensions..

    - by devdreamers
    Hi all, I was working on a very simple extension, where on clicking extension icon, a webpage is opened in a new tab, the webpage has HTML frames, within which lies a textbox. I want to set a value for the same. The webpage which opens has: <HTML> <FRAMESET rows="15%, *" border="0"> <FRAME src="./files/abc.htm" id="abc_frame" name="abc_frame" onload="abcLoad()" scrolling="NO"> </FRAMESET> </HTML> and abc.htm has: <div align="center" valign="bottom" style="font-size: 1em;"> <form onSubmit="javascript:navigate(this);return false;"> <label for="loc">Loc</label>: <input type="text" size="50" id="loc" value="http://google.com"/> <input name="go" type="submit" value="Go" id="loc_go" onclick='navigate(this); return false;'/> </form> </div> how can I replace current textbox value with, say http://yahoo.com ? I guess, Content Script in Chrome extensions is required, but not sure, how/what should be it's code/content. Please guide/help. Thanks a lot. Appreciate it.

  • Silverlight: How can I built an overview display block for any XAML?

    - by Ryan Bates
    Hi all, I am trying to create a generic "overview" control for any XAML. A good example of the desired effect would be on Google Maps or Bing maps: The main map zooms into some content, while a small "overview" block is docked to one of the map corners, showing the user where he/she is zoomed into. My content is all placed inside a <Canvas>, which can then be scaled and zoomed with transforms. While the user does this kind of navigation, I would like to give them a visual indication of where they are in the larger context of the content. I have tried to take a 'screenshot' of the XAML before the user starts navigating, i.e. create a WriteableBitmap wbImageData = new WriteableBitmap(TheCanvas, null); and then displaying it in an Image. Based on the user's scrolling and zooming activity, a Rectangle displays which part of the content is currently visible in the display area. This works OK-ish (still clunky), but the image has to be redone everytime the content changes. Is there a simple way to create this kind of preview, or does anyone know of a component that does it? Thanks!

  • Adding an unknown number of JComponents to a JPanel

    - by Matthew
    Good day, I am building an Applet (JApplet to be exact) and I sub divided that into two panels. The top panel is called DisplayPanel which is a custom class that extends JPanel. The bottom panel is called InputPanel which also extends JPanel. As mentioned above, I can add those two Panel's to the applet and they display fine. The next thing that I would like to do is have the InputPanel be able to hold a random number of JComponent Objects all listed veritcally. This means that the InputPanel should be able to have JButtons, JLabels, JTextFields etc thrown at it. I then want the InputPanel to display some sort of scrolling capability. The catch is that since these two panels are already inside my applet, I need the InputPanel to stay the same size as it was given when added to the Applet. So for example, if my applet (from the web-browser html code) was given the size 700,700, and then the DisplayPanel was 700 by 350, and the InputPanel was below it with the same dimensions, I want to then be able to add lots of JComponents like buttons, to the InputPanel and the panel would stay 700 x 350 in the same position that it is at, only the panel would have scroll bars if needed. I've played with many different combinations of JScrollPane, but just cannot get it. Thank you.

  • Moving UIScrollView in App

    - by jsetting32
    Currently, I am attempting to create the same effect as Yahoo! Weather's App where the vital day information is at the bottom of the page on the top of a UIScrollView, that's contained by a UIView. I am having a hard time thinking about how this is going to happen or how I should implement this. If the user taps on the top of the UIScrollView which is located near the bottom of the laoded UIView, and starts to scroll up (/), the UIScrollView's frame should be moved to the TOP of the current UIView's frame. So the UIScrollView's y-value should change to UIView's (self.view.frame.origin.y) if the user starts scrolling UP on the UIScrollView which is located on the UIView's y-pixel ~280. Here's what the UIViewController should look like in the beginning of loading the ViewController... Then once the user slides his finger from the bottom to the top of the screen... this should happen........ And when the user scrolls to the top of the UIScrollView with all the content within it... the view should go back to the start picture shown... How is this done? I was thinking several UIGestureRecognizer's and Instantiating the UIscrollview at the lower part of the UIView... _weatherView = [[UIScrollView alloc] initWithFrame:CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y + 250, self.view.bounds.size.width, self.view.bounds.size.height - 44)]; _weatherView.contentSize = CGSizeMake(self.view.bounds.size.width, self.view.bounds.size.height * 4); _weatherView.backgroundColor = [UIColor clearColor]; [self.view addSubview:_weatherView]; The adding some UIGestureRecognizer delegate method.... But anyone have any ideas on the UIGestureRecognizer delegate method? And how it should be implemented? I can write the psuedo-code but I am having problems finding the delegate methods :P Thank you!!! ---- Break Time.... :)

  • How can I store large amount of data from a database to XML (memory problem)?

    - by Andrija
    First, I had a problem with getting the data from the Database, it took too much memory and failed. I've set -Xmx1500M and I'm using scrolling ResultSet so that was taken care of. Now I need to make an XML from the data, but I can't put it in one file. At the moment, I'm doing it like this: while(rs.next()){ i++; xmlStringBuilder.append("\n\t<row>"); xmlStringBuilder.append("\n\t\t<ID>" + Util.transformToHTML(rs.getInt("id")) + "</ID>"); xmlStringBuilder.append("\n\t\t<JED_ID>" + Util.transformToHTML(rs.getInt("jed_id")) + "</JED_ID>"); xmlStringBuilder.append("\n\t\t<IME_PJ>" + Util.transformToHTML(rs.getString("ime_pj")) + "</IME_PJ>"); //etc. xmlStringBuilder.append("\n\t</row>"); if (i%100000 == 0){ //stores the data to a file with the name i.xml storeKBR(xmlStringBuilder.toString(),i); xmlStringBuilder= null; xmlStringBuilder= new StringBuilder(); } and it works; I get 12 100 MB files. Now, what I'd like to do is to do is have all that data in one file (which I then compress) but if just remove the if part, I go out of memory. I thought about trying to write to a file, closing it, then opening, but that wouldn't get me much since I'd have to load the file to memory when I open it. P.S. If there's a better way to release the Builder, do let me know :)
