  • [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

  • Jquery UI Dialog - when opened IE7 Browser moves instantly to the bottom of the page

    - by Truegilly
    Hello, i have been working on a new .net MVC site and have integrated some of the awesome jquery UI components. ive been testing it in IE8, FF, opera and Chrome and all looks well. Once I test in IE7, surprisingly its the dialogs that are causing a problem. basically what’s happening is that one you user clicks to open a dialog the page will scroll immediately to the bottom of the page. This is especially bad if the page is quite long. this only happens in IE7 (and probably 6 but im not even going there!). I have spend a few hours reading forums and it seems im not the only one. I have created a dirty hack which im not keen on but it does work. onclick="SignIn(); <% if(ModelHelperClass.CheckForOldIEVersion() == true) Response.Write("window.scrollTo(0, 0);"); %> return false;"> has anyone else had this issue and resolved it without resorting to dirty hacks ? im using jquery-ui-1.8.custom.min.js and jquery-1.4.2.min.js any help is most appreciated Truegilly

  • How can I optimize this or is there a better way to do it?(HTML Syntax Highlighter)

    - by Tanner
    Hello every one, I have made a HTML syntax highlighter in C# and it works great, but there's one problem. First off It runs pretty fast because it syntax highlights line by line, but when I paste more than one line of code or open a file I have to highlight the whole file which can take up to a minute for a file with only 150 lines of code. I tried just highlighting visible lines in the richtextbox but then when I try to scroll I can't it to highlight the new visible text. Here is my code:(note: I need to use regex so I can get the stuff in between < & characters) Highlight Whole File: public void AllMarkup() { int selectionstart = richTextBox1.SelectionStart; Regex rex = new Regex("<html>|</html>|<head.*?>|</head>|<body.*?>|</body>|<div.*?>|</div>|<span.*?>|</span>|<title.*?>|</title>|<style.*?>|</style>|<script.*?>|</script>|<link.*?/>|<meta.*?/>|<base.*?/>|<center.*?>|</center>|<a.*?>|</a>"); foreach (Match m in rex.Matches(richTextBox1.Text)) { richTextBox1.Select(m.Index, m.Value.Length); richTextBox1.SelectionColor = Color.Blue; richTextBox1.Select(selectionstart, -1); richTextBox1.SelectionColor = Color.Black; } richTextBox1.SelectionStart = selectionstart; } private void pasteToolStripMenuItem_Click(object sender, EventArgs e) { try { LockWindowUpdate(richTextBox1.Handle);//Stops text from flashing flashing richTextBox1.Paste(); AllMarkup(); }finally { LockWindowUpdate(IntPtr.Zero); } } I want to know if there's a better way to highlight this and make it faster or if someone can help me make it highlight only the visible text. Please help. :) Thanks, Tanner.

  • Absolutely positioned div on right causing scrollbar when the left doesn't

    - by Michael Snyder
    I'm trying to "flank" a centered div with some design elements that are absolutely positioned outside the main div's width. I'm getting a scroll bar due to the element on the right, but not the element on the left (IE6/7/8, Chrome, Firefox). How can I get rid of that horizontal scrollbar? <html> <head> <style type="text/css"> html, body { height: 100%; width: 100%; margin: 0; } body { text-align: center; } .wrapper { margin: 0 auto; position: relative; width: 960px; z-index: 0; } .main { background: #900; height: 700px; } .right, .left { position: absolute; height: 100px; width: 100px; } .right { background: #090; top: 0px; left: 960px; z-index: 1; } .left { background: #009; top: 0px; left: -100px; z-index: 1; } </style> </head> <body> <div class="wrapper"> <div class="main"></div> <div class="left"></div> <div class="right"></div> </div> </body> </html>

  • ScrollView content async downloading problem

    - by Newbee
    Hi! I have UIScrollView with lots of UIImageView inside. In the loadView method I assign some temporary image for each of subview UIImageView images and starts several threads to async download images from internet. Each thread downloads and assign images as follows: NSData *data = [NSData dataWithContentsOfURL:URL]; UIImage *img = [UIImage imageWithData:data]; img_view.image = img; Here is the problem - I expects picture will changed after each image downloaded by I can see only temporary images until all images will downloads. UIScrollView still interact while images downloads - I can scroll temporary images inside it and see scrollers and nothing blocks run loop, but downloaded images doesn't updates.. What I tried to do: Call sleep() in the download thread -- not helps. Call setNeedsDisplay for each ImageView inside ScrollView and for ScrollView -- not helps. What's wrong ? Thanks. Update. I tried some experiments with number of threads and number of images to download. Now I'm sure -- images redraws only when thread finished. For example - if I load 100 images with one thread -- picture updates one time after all images downloads. If I increase number of threads to 10 -- picture updates 10 times -- 10 images appears per update. One more update. I fixed problem by staring new thread from the downloading threads each time one image downloaded and exit current thread (instead of download several images in one thread in the cycle and exit thread only when all downloaded). Obviously it's not a good solution and there must be right approach.

  • iPhone UIScrollView embedded UIView is clipped

    - by scc
    Hello. I have an iPad UIView subclass (we'll call LargerUIView) with which I do a bunch of drawing via drawRect: once asked. That all appears to be working, and looks the way I like. I'm at the point now of trying to get scrolling working (just in the horizontal to begin), yet when I try to scroll, what shows below is black (ie, appears to have never been drawn). That doesn't surprise me as it's likely been clipped. Looking for suggestions. Here's what I'm doing so far: MyAppDelegate.m - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { CGRect scrollRect = CGRectMake(0, 0, 768, 1024); UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:scrollRect]; LargerUIView *view = (LargerUIView *)[viewController view]; [scrollView addSubview:view]; [scrollView setContentSize:CGSizeMake(768, pageHeight)]; [scrollView setContentMode:UIViewContentModeRedraw]; [scrollView setClipsToBounds:YES]; [window addSubview:scrollView]; [scrollView release]; // Without this next line, the "frontmost" (ie, most recently added subview) // is the MoxiesAppetizerMenu - which is not equipped to handle scrolling/UIEvents [window sendSubviewToBack:view]; // Show it all. [window makeKeyAndVisible]; return YES; } Any suggestions? Have tried changing "setClipsToBounds" to NO as well.

  • Drag/drop problem (draggable in position:relative parent)

    - by MackDaddy
    Here's the scenario, I'm using prototype and scriptaculous, but I believe jquery would have the same issue. I have a list draggable images in a relatively positioned div. The problem is I can't drag the images out of the parent div... well... you can, they're just not visible. If you remove the position:relative on the parent div, it works just fine, I can drag items out of the div perfectly. However because of this little IE7 bug: http://snook.ca/archives/html%5Fand%5Fcss/position%5Frelative%5Foverflow%5Fie/ that position:relative is required. IS there another work around to this bug that does not require setting position? I've tried playing with z-index and everything I can think of to no avail. Here's the CSS for the box: #products{ width: 680px; height: 400px; border: 1px solid gray; /*background-color: #66FF00;*/ overflow-y: scroll; overflow-x: hidden; font-family:"Helvetica Neue","Helvetica"; font-size:12px; font-weight:bold; position: relative; } If you would like to see this bug in action, you can visit it here: http://twinmed-dev.com/template%5Fadd.php. Try searching for an item like "gloves" then adding it to the cart below. Thanks for any help.

  • Background image help (Solved)

    - by J2
    thanks for help, ended up with this html{ position:relative; min-width:950px; height:100%; background:black url(images/GrassBG.png) repeat-y top center; font:13px "Lucida Grande",Helvetica,Arial,sans-serif; } body.main{ width:950px; margin:0 auto; position:relative; } is there any way when using a div for a background image- to limit the height to only the content displayed? im putting the background image in a div because i want it centered via position:relative but the image doesnt show up unless i put a height on the div, and thats not what i want because i dont want to be able to just scroll down to the bottom of the image where theres no content ive tried putting the background image on the body css but if the browser is less than the width of the image, it just throws it over to the left and you can only see half of it- is there no way to make the background position:relative on the body? sorry if that doesnt make sense < thanks why can you not use Position:relative; on the body?

  • How can I create a finger scrollable Textbox in WM 6.5?

    - by Papajohn
    Hi everybody. I just noticed something weird in WM 6.5 emulators. Unlike 6.1 where finger panning kind of worked, the only way to scroll a Textbox appears to be through scrollbars. This behaviour is in contrast to what they have done for comboboxes: they are now gesture-friendly without the programmer's intervention. I.e. the user can select a choice from a standard drop down menu by panning and scrolling. Previously, you had to use the embedded scrollbar. The combobox's case implies that MS took some measures to provide standard gesture support for classic finger gestures, yet I cannot see something similar for textboxes. This makes me ask the following: Is there anything that can be done to make textboxes finger scrollabe easily? Note that I refer to managed .NET CF development. It is my understanding that in native development I could use the new Gestures API to achieve the scrolling effect. Yet, I am not sure if there is an easier and more straightforward method that I have missed.

  • SparkDataContainer Scroller not scrolling to bottom of container

    - by AZSL
    I am using a scroller component within a custom skin for a SkinnableDataContainer. I am running into an issue in that the thumbbar of the scroller stops at about the 50% point, however this is actually the end of the scrollable area. In actuality, the thumbbar should be at the bottom of the scroll track. Here's the code for the scroller: <s:SparkSkin xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/halo" bottom="150" > <!-- Properties of the parent ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ --> <s:states> <s:State name="normal" /> <s:State name="disabled" /> </s:states> <!-- Metadata ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ --> <fx:Metadata> [HostComponent("spark.components.SkinnableDataContainer")] </fx:Metadata> <!-- UI components ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ --> <s:Rect left="0" right="0" bottom="0" top="0" radiusX="4" radiusY="4" > <s:fill> <s:SolidColor id="fillColor" color="0xEFEFEF"/> </s:fill> </s:Rect> <s:Group width="905" height="395" id="mainGroup"> <s:Scroller left="10" right="10" top="4" bottom="10" > <s:DataGroup id="dataGroup" /> </s:Scroller> <s:Rect left="0" right="0" top="0" bottom="0"> <s:stroke> <s:SolidColorStroke weight="1" color="0xD8D8D8"/> </s:stroke> </s:Rect> </s:Group>

  • CSS Design question, I've got myself completely turned around.

    - by Matt Dawdy
    Okay, I have a couple of other questions out there, but I think I'd better just ask from the beginning how you CSS experts would do this. Client's page is split into 2 rows -- header has some info, some aligned to left of page, some to right, some in the middle. This is currently done using a table. I'm fine with leaving this alone or changing it. My real question is that I need a page layout to handle the following: 2 columns - column on left is 200px, but can be "close" down to to 10px (not a slider, it's either 200 or 10 px). The column on the right needs to be as big as it needs to be -- which might be larger than the width of the page. When left column is "closed" then the right column slides over of course. Again, this right column might be 300px or it might be 4000 pixels (it's a reporting interface). Now, to add another wrinkle, SOME pages have 3 columns. The first 2 columns are each exactly 200px, and both can be "closed" down to 10 px each. But, the user may not close both columns, maybe just 1. Or none. Or both. The third column needs to act just like I described above, being able to be larger than the page width, and sliding over to take advantage of any of the "closed" left columns. Whew! I'm pretty confused as to how to go about this, as either I get it right but I can't scroll over to the right at all (overflow: hidden) and information is lost, or the right column jumps down below the left 2 columns and just looks plain stupid. My minimum browser requirements are IE8, FF3.5, Chrome and Safari (latest versions of all). Any and all pointers are gladly accepted.

  • Presenting an image cropping interface

    - by wkw
    I'm trying to engineer a UI for cropping images in iphone OS and suspect I'm going about things the hard way. My goal is pretty much what the Tapbots duo have done with Pastebot. In that app, they dim the source image but provide a movable and resizable cropping view and the image you're cropping is in a zoomable scrollview; when you resize or move the underlying image, the cropping view adjusts appropriately. I mocked up a composite image which will give a sense of the design I'm after, along with how I presently have my view hierarchy setup, viewable here The approach I've started with is the following: UIImageView with the image to crop is in a scrollview, a plain UIView with black fill and suitable transparency/alpha setting is added in front of the imageview. I then use a custom UIView which is a sibling to the scrollview at a higher level, which implements the drawRect: method and for the most part calls CGImageCreateWithImageInRect to get the portion of the image's bitmap that matches the position of the cropping view and draws that to the CGContext. in the viewcontroller I'm using the UIScrollViewDelegate methods to track scrolling and passing those changes to the custom cropping UIView so it stays in sync with the scroll contentOffset. That much is finally working. But trying to keep in sync as the scrollview zoomScale changes is when I figured I should ask for help. Looking for suggestions or guidance. My initial approach just seems like more work than is required. Could this be done with a masking layer in the ImageView? And if so, how would I setup the tracking for moving and resizing the cropping rect? My experience working with layers is non-nil, but very limited thus far.

  • AdvancedDataGrid dynamic text Value Coloring - ItemRenderer problem

    - by sri
    In my AdvancedDataGrid, I am adding dynamic values to cells by dragging a cell value to other cells. While copying, I am setting the value to listData and setting the Red color to the value in ItemRenderer. Everything is working fine, but when I scroll down/up, the values remains in the cells where thay are supposed to be(as I am setting to listData) but the coloring behaves wierd(as I am trying to set the color in ItemRenderer). I don't want to store the color of the value, but I should be able to see the dynamically created values in Red color. Is there a way, I can do this? Do I need to set the color to actual dataprovider object and then check in ItemRenderer? Can anyone help me with this? public class CustomItemRenderer extends AdvancedDataGridItemRenderer { private var _isDynamicValue:Boolean; .... .... //_isDynamicValue is set to true if the value is dynamic if(_isDynamicValue && listData.label) { setStyle("color", 0xFF0000); setStyle("fontWeight", "bold"); } else { setStyle("color", 0x000000); }

  • NSOperation for animation loop causes strange scrolling behaviour

    - by Tricky
    Hi, I've created an animation loop which I run as an operation in order to keep the rest of my interface responsive. Whilst almost there, there is still one remaining issue. My UIScrollViews don't seem to be reliably picking up when a user touch ends. What this means is, for example, if a user drags down on a scroll view, when they lift their fingers the scrollview doesn't bounce back into place and the scrollbar remains visible. As if the finger hasn't left the screen. It takes another tap on the scrollview for it to snap to its correct position and the scrollbar to fade away... Here's the loop I created in a subclassed NSOperation: (void)main { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSRunLoop *runLoop = [NSRunLoop currentRunLoop]; _displayLink = [[CADisplayLink displayLinkWithTarget: self selector: @selector(animationLoop:)] retain]; [_displayLink setFrameInterval: 1.0f]; [_displayLink addToRunLoop:[NSRunLoop currentRunLoop] forMode: NSRunLoopCommonModes]; while (![self isCancelled]) { NSAutoreleasePool *loopPool = [[NSAutoreleasePool alloc] init]; [runLoop runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]]; [loopPool drain]; } [_displayLink invalidate]; [pool release]; } DOes anyone have any idea what might be going on here, and even better how to fix it... Thanks!

  • How to use my trackpad for horizontal mousewheel scrolling in a Java AWT ScrollPane

    - by blissapp
    Like many modern mice and trackpads, my laptop supports vertical and horizontal scrolling. It's an addictive feature once you get used to it. I simply want my Java apps to support horizontal scrolling via the trackpad/mousewheel, but everywhere I search it seems that this is not possible in Java. I really want someone to tell me that I'm somehow doing it wrong, this feature is already requested behaviour: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6440198 The inability to do this simple thing is actually a deal breaker for the app I'm working on. In fact, for any app I can envision! I've invested a bit of time in the Java backend, so I'd really like to find a solution for this seemingly simple thing. Question is what could I do to implement this behaviour? Are raw OS level events even exposed to java, would I then need to write this from scratch? import java.awt.*; public class ScrollExample extends Canvas { public void paint(Graphics g) { g.setColor(Color.green); g.fillOval(0,0,400, 400); } public static void main(String[] args) { ScrollExample b = new ScrollExample(); Frame f = new Frame ("Scroll Example"); ScrollPane scroller = new ScrollPane (ScrollPane.SCROLLBARS_ALWAYS); scroller.add(b,"Center"); f.setPreferredSize(new Dimension(500,500)); f.add ("Center",scroller); f.pack(); f.show(); } }

  • How do I get textbox to fill the column and autoscroll?

    - by Stephen Price
    I have the following code in my DataGridTemplateColumn: <Controls:DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <TextBox Text="{Binding AlternateTeacherName, Mode=TwoWay}" Style="{StaticResource InputTextBox}"/> </StackPanel> </DataTemplate> Style is: <Style x:Key="InputTextBox" TargetType="TextBox" > <Setter Property="Margin" Value="1" /> <Setter Property="MinWidth" Value="30" /> <Setter Property="BorderThickness" Value="0" /> <Setter Property="Background" Value="Transparent" /> <Setter Property="VerticalAlignment" Value="Center" /> <Setter Property="TextAlignment" Value="Left" /> <Setter Property="HorizontalAlignment" Value="Stretch" /> Problem I'm getting is that the textbox fills the column width correctly (including when you resize it) but if I type into the textbox the cursor is not visible when it reaches the end of the line. I'd like the text to scroll off the left so that the current text is still visible. thanks

  • DisplayObject snapshot in flex 3

    - by simplemagik
    i'm creating a visual editor in flex and need to let users export thier projects into Image format. But i have one problem: size of the canvas is fixed and when user add element which is out of these sizes some scroll bars added. And user continue working on the project. but when he want to take snapshot of the canvas he just get the visible part ot the canvas with scrollbars. how to get image of the fullsize canvas? The only solution i found is to check the positions and sizes of canvas child objects and rezise it to fit them. then take snap and resize back. But it hmmmm... too complicated i think. Is there some "easy methods"? <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical"> <mx:Script> <![CDATA[ import mx.graphics.ImageSnapshot; private function SnapshotButtonHandler():void { var snapshot:ImageSnapshot = ImageSnapshot.captureImage(AppCanvas); var file:FileReference = new FileReference(); file.save(snapshot.data, "canvas.png"); } ]]> </mx:Script> <mx:Canvas id="AppCanvas" width="800" height="300" backgroundColor="0xFFFFFF"> <mx:Box x="750" y="100" width="100" height="100" backgroundColor="0xCCCCCC" /> </mx:Canvas> <mx:Button id="SnapshotButton" label="take snapshot" click="SnapshotButtonHandler()" /> </mx:Application>

  • Chrome is leaking memory, when jQuery is used on events?

    - by user269386
    Hi, I'm experiencing an increase of memory usage, when I use the jQuery-eventhandling in Chrome. I've tested it with IE and FF as well, but there I couldn't see a suspicious rise of memory-usage, compared to Chrome. I'm using Chrome version 4.0.223.16 (unfortunately I'm forced to use this version, here) Simple example here. Just scroll with the mousewheel in the red box and open the Chrome-taskmanager and you will see an increase of memory which won't be released anymore: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <script type="text/javascript" src="js/libs/jquery-1.4.2.min.js"></script> <script type="text/javascript"> jQuery(function () { jQuery("#div1").bind("mousewheel", function (event) { event.preventDefault(); }); }); </script> </head> <body> <div id="div1" style="width: 100px; height: 100px; background-color: red;"></div> </body> </html> Does anyone have experienced the same problem (or is it maybe solvend with a different version of chrome)? And does anyone have a fix for it? thanks

  • How can I create a properly sizing QWebView?

    - by chacham15
    I want to make a QWebView appear expanding to the width and height so that ideally it will have no scroll bars. Some websites may have fixed widths that wont allow this, but I am not concerned with those. In any case, I cannot do as I wish because QWebView implements sizeHint as follows: QSize QWebView::sizeHint() const { return QSize(800, 600); // ####... } This is incorrect on a number of levels. 1. It doesnt at all take into account the size of the actual web page. 2. It doesnt take into account that the height and width are related to each other. (To prove #2 think about text in web pages that wraps to the next line.) As a simple fix I tried to do (where QResizingWebView extends QWebView): QSize QResizingWebView::sizeHint() const{ return this-page()-mainFrame()-contentsSize(); } While this is closer to the result, it also has 2 flaws. 1. It doesnt take into account the relation between the displayed width/height. 2. this->page()->mainFrame()->contentsSize() is inaccurate from what I can tell from my preliminary testing (it has returned heights larger than it should under many cases, although this may be related to #1). Does anyone have any tips to fix this?

  • Center a TextBox over the top of a ScrollViewer in WPF.

    - by Eric
    I have a MainView that contains a navigation bar which selects one of many XAML pages to be displayed in the page view pane. The MainView contains a ScrollViewer around the pages. This allows the pages to be whatever size they need to be and the MainView's ScrollViewer scrolls them. This all works great. On one of the pages, I need to (sometimes) center a TextBox in the middle of the page view pane (over the top of the page content). This was easily done by placing both the page content and the TextBox overlapping each other in a Grid (and I hide the TextBox as necessary). This all seems to work great. However, if the page content grows to be larger than the pane, the TextBox is centered not on the pane, but on the full page content. Thus, it moves from center screen down and/or to the right (and eventually off the screen). Bummer. Options: Remove the ScrollViewer from the MainView. This would require placing one on every page! Argh. Do option #1, and create a ScrolledPage base class. This is a lot of work, and I'm worried about tools issues (Blend issues). It also requires changing every page (to subclass this page). Somehow override the ScrollViewer on just this page. Then, place another ScrollViewer on the page content to Scroll it. Option 3 seems preferable, because it contains the issue to just modifying this page (instead of changing the rest of the pages). However, I can't figure out how to do it. Ideas? Thanks in advance!

  • Suggested (simple) approach for drawing large numbers of visual elements in WPF?

    - by Ender
    I'm writing an interface that features a large (~50000px width) "canvas"-type area that is used to display a lot of data in a fairly novel way. This involves lots of lines, rectangles, and text. The user can scroll around to explore the entire canvas. At the moment I'm just using a standard Canvas panel with various Shapes placed on it. This is nice and easy to do: construct a shape, assign some coordinates, and attach it to the Canvas. Unfortunately, it's pretty slow (to construct the children, not to do the actual rendering). I've looked into some alternatives, it's a bit intimidating. I don't need anything fancy - just the ability to efficiently construct and place objects in a coordinate plane. If all I get are lines, colored rectangles, and text, I'll be happy. Do I need Geometry instances inside of Geometry Groups inside of GeometryDrawings inside of some Panel container? Note: I'd like to include text and graphics (i.e. colored rectangles) in the same space, if possible.

  • Scrollbar with Sprite and Rectangle won't move text, just the Rectangle it's painted on.

    - by WebDevHobo
    Warning: school assignment. For those of you still with me, I am tasked with making some scrollable content in Flash. Load in a TextFile using LoadURL(), then display it. To get the text, we've written our own class TextFieldExtended, which is basically just there to give the textfile location to the constructor and then have the class do the various steps of getting it and loading it for you. So I needed to get a Scrollbar, which I got here: http://kirupa.com/forum/showthread.php?t=245468 (all files in a zip linked at the end of this text) The thing is, it works with Sprites. After trying to get it to accept TextFieldExtended, I bumped into a block, since the scrollbar relied heavily on a Sprite property that TextFieldExtended didn't have or could have. So I tried adding the TextFieldExtended instance to a Sprite instance using addchild. A problem occurs here that I do not know how to handle. It seems that a Rectangle is drawn and the Text is drawn on that. I say this because the scrollbar moves the Rectangle up and down a bit, but the text doesn't scroll, just the Rectangle it is positioned in and the text then moves along with it. My question: can this be fixed, or is does this implementation of scrollbars need a lot of adaptations before this is possible? If so, any scrollbars you can recommend, because it's too extended for me at this point. All files: http://www.mediafire.com/?q2ium22gmox This was made in Flash CS4 using ActionScript3. The Example class is the final implementation

  • UIView Animation Inconsistent Result

    - by Josh Kahane
    I am trying to make use of UIView animation to slide my views across the screen. I have a UIScrollView in my view controller, in which I have my UIViews. I alos have this method: -(void)translateView:(UIView *)view toRect:(CGRect)rect withDuration:(CGFloat)duration { [UIView animateWithDuration:duration animations:^ { view.frame = rect; } completion:^(BOOL finished) { //Finished }]; } I call this to move my UIView in an animated fashion to a CGRect of my choice over a certain time. I have a loop which creates and slides out 7 views. This works great, I call it like below, the loop of course calling this 7 times on different views: [self translateView:cell toRect:translationRect withDuration:0.7]; However, I can't then call this again immediately afterwards, just nothing happens. Although, lets say I call this again after a 2 second NSTimer, the animation does run, but then when i scroll my UIScrollView, the view I just animated jumps back to its previous CGRect. Hope you can help, its all feeling very un-explanetory, Ill post more code if it isn't making any sense, thanks.

  • UIImage - should be loaded with [UIImage imageNamed:@""] or not ?

    - by sagar
    Hello ! every one. I am having number of images with in my application. ( images more than 50 - approximately & it can extend according to client's need ) Each image are very large round about - 1024 x 768 & 150 dpi Now, I have to add all this images in a scroll view & display it. Ok, My question is as follows. According to me there are two options of loading large images imageNamed:@"" load asynchronously when viewDidLoad Called. Which is more preferable ? imgModel.image=[UIImage imageNamed:[dMain valueForKey:@"imgVal"]]; or like this. NSURL *ur=[[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:lblModelName.text ofType:@"png"] isDirectory:NO]; NSURLRequest *req=[NSURLRequest requestWithURL:ur cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:40]; [ur release]; NSURLConnection *con=[[NSURLConnection alloc] initWithRequest:req delegate:self]; if(con){ myWebData=[[NSMutableData data] retain]; } else { } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [myWebData setLength: 0]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [myWebData appendData:data]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { [connection release]; } -(void)connectionDidFinishLoading:(NSURLConnection *)connection { NSLog(@"ImageView Ref From - %@",imgV); // my image view & set image imgV.image=[UIImage imageWithData:myWebData]; [connection release]; connection=nil; }
