  • Define Javascript slider hit/rollover area

    - by Rob
    Hey, Im having an issue defining the hit area for a javascript sliding element. See example: http://www.warface.co.uk/clients/warface.co.uk/ Please slide over the grey box on the right side to reveal the button, although this works I would only like for the slider to only be triggered by rolling over the red block. CSS .slidingtwitter { /* -- This is the hit area -- */ background: #ccc; width:255px; height:55px; overflow: hidden; top:50%; right: 0px; /* -- This is the sliding start point -- */ position: fixed; font-family: Gotham, Sans-Serif; z-index: 50; } .slidingtwitter.right { right:0px; } .slidingtwitter .caption { /* -- This is the sliding area -- */ background: #fff; position: absolute; width:260px; height:55px; right: -205px; /* -- This is the sliding start point -- */ } .slidingtwitter a { color: #484848; font-size: 20px; text-transform: uppercase; } .slidingtwitter a:hover { color: black; } .slidingtwitter .smaller { font-size: 12px; font-family: Gotham Medium; } .twitterblock { background: #f35555 url("styles/images/button_twitter.png") no-repeat 14px 15px ; width:35px; height:35px; padding:10px; float:left; display:block; } .slidingtwitter .followme { background: url("styles/images/button_arrowheadthin.jpg")no-repeat right 0; height:35px; display:block; float:left; line-height:14px; width:140px; margin:10px 0px 0px 14px; padding-top:6px; padding-right: 40px; } JS $('.slidingtwitter').hover(function(){ $(".slide", this).stop().animate({right:'0px'},{queue:false,duration:400}); //Position on rollover },function() { $(".slide", this).stop().animate({right:'-205px'},{queue:false,duration:400}); //Position on rollout }); Any suggestions would be much appreciated.

  • Codeigniter not returning me to upload form after image upload.

    - by Drew
    I'm still very new to codeigniter. The issue i'm having is that the file uploads fine and it writes to the database without issue but it just doesn't return me to the upload form. Instead it stays in the do_upload and doesn't display anything. Even more bizarrely there is some source code behind the scenes. Can someone tell my what it is i'm doing wrong because I want to be returning to my upload form after submission. Thanks in advance. Below is my code: Controller: function do_upload() { if($this->Upload_model->do_upload()) { $this->load->view('home/upload_form'); }else{ $this->load->view('home/upload_success', $error); } } Model: function do_upload() { $config['upload_path'] = './uploads/'; $config['allowed_types'] = 'gif|jpg|png'; $config['max_size'] = '2000'; $this->load->library('upload', $config); if ( ! $this->upload->do_upload()) { $error = array('error' => $this->upload->display_errors()); return $error; } else { $data = $this->upload->data(); $full_path = 'uploads/' . $data['file_name']; $spam = array( 'image_url' => $full_path, 'url' => $this->input->post('url') ); $id = $this->input->post('id'); $this->db->where('id', $id); $this->db->update('NavItemData', $spam); return true; } } View (called upload_form): <html> <head> <title>Upload Form</title> </head> <body> <?php if(isset($buttons)) : foreach($buttons as $row) : ?> <h2><?php echo $row->image_url; ?></h2> <p><?php echo $row->url; ?></p> <p><?php echo $row->name; ?></p> <p><?php echo anchor("upload/update_nav/$row->id", 'edit'); ?></p> <?php endforeach; ?> <?php endif; ?> </body> </html>

  • jQuery i++ and i-- problems ... what on earth???

    - by michael
    Could someone please tell me what I am doing wrong? I'm not a newbie at programming but I feel like it tonight! Every time I increment the incrementing variable it throws a fit! When add one to it, it behaves fine, but if I try to add one more to it it wants to add 2 more. And then if I try to de-increment it wants to subtract from the original number that it was assigned to. I've tried: i++; i = i+1; i = i++; Nothing seems to work. It's got to be a stupid mistake. Press the buttons to increment and de-increment. http://michaelreynolds.net/iphone/ here's the code: var dayNum = 30; //---------------------------------------------------------------------- $.jQTouch({ icon: 'dailyqoteicon.png', statusBar: false, initializeTouch: 'a.touch' }); //---------------------------------------------------------------------- $(document).ready(function(){ //$(function(){}); $(function(){ $('a.touch').swipe( function(event, info){ //alert("jQTouch swipe event"); //alert(info.direction); }); }); $(function updateVerse(){ //alert("updateVerse called"); $.ajax({ type: "GET", dataType: 'JSON', data: 'day='+ dayNum, url: 'forward.php', success: function(data){ var obj = $.parseJSON(data); $("h2.quote").html(""); $("h3.reference").html(""); $("h2.quote").append(obj.quote); $("h3.reference").append(obj.reference, " ", obj.version); //$("span.version").append(obj.version); //----------------------------------- // JSON string {"id":"1","quote":"For to me, to live is Christ, and to die is gain","reference":"Philippians 1:21","version":"NKJV"} }, error: function(request, error){ alert("problem retrieving json data string"); } }); function addDayNum(){ dayNum = dayNum + 1; //dayNum = dayNum++; } function subDayNum(){ dayNum = dayNum - 1; //dayNum = dayNum--; } $("div#header a.next").tap( function(){ addDayNum(); //dayNum++;// doesn't work at all //dayNum = dayNum + 1;//doesn't work at all updateVerse(); //alert(dayNum); //alert("next clicked"); }); $("div#header a.prev").live('click', function(){ subDayNum(); //dayNum--;//doesn't work at all //dayNum = dayNum - 1;// doesn't work at all updateVerse(); //alert(dayNum); //alert("previous clicked"); }); }); });

  • Showing div based on filled form field

    - by Fabio
    I have this script where I use a slider to show some elements of a form. So far so good. The way I'm doing it is by having a slider (can't use a multistep form since it uses a plugin not allowing multistep forms, plus some graphic behaviors) and a button that goes to the next slider. So now I need that button (not part of the form) to show only if a certain field is filled. I tried teh following, but it's not working, I assume some error but can't figure what. My code is as follows: $('#clientname').change(function() { var clientVal = $("input").val() == ''; $(".next").hide(); if ($('#clientname').val() != '').show(); else $('.next').hide(); }); and the html as follows: <div class="b40-right"> <h3>The Basics</h3> <div class="label"> Your Name (required)</div> <div class="inputes"> <span class="wpcf7-form-control-wrap your-name"><input id="clientname" type="text" name="your-name" value="" class="wpcf7-form-control wpcf7-text wpcf7-validates-as-required" size="40" /></span> </div> <div class="label">Your Email (required)</div> <div class="inputes"> <span class="wpcf7-form-control-wrap your-email"><input type="text" name="your-email" value="" class="wpcf7-form-control wpcf7-text wpcf7-email wpcf7-validates-as-required wpcf7-validates-as-email" size="40" /></span> </div> <div class="label">Type of Business</div> <div class="inputes"> <span class="wpcf7-form-control-wrap type-of-business"><textarea name="type-of-business" class="wpcf7-form-control wpcf7-textarea" cols="40" rows="10"></textarea></span> </div> </div> <a class="next" href="javascript:stepcarousel.stepBy('mygallery2', 1)"><img id="nextbut1" src="<?php bloginfo('template_directory'); ?>/images/next.png" alt="" /></a> any help on what am I doing wrong? Is there a better approach/solution? (I'm not a programmer as you may figure) Thank you in advance!

  • UpdatePanel Full Postback

    - by Korivo
    Greetings, here is the scenario. I have and .aspx page with and updatepanel like this <asp:UpdatePanel id="uPanelMain" runat="server"> <ContentTemplate> <uc:Calendar id="ucCalendar" runat="server" Visible="true" /> <uc:Scoring id="ucScoring" runat="server" Visible="false" /> </ContentTemplate> The control ucCalendar is loaded first and it contains a grid like this <asp:DataGrid CssClass="grid" ID="gridGames" runat="server" AutoGenerateColumns="False" HeaderStyle-CssClass="gridHeader" ItemStyle-CssClass="gridScoringRow" GridLines="None" ItemStyle-BackColor="#EEEEEE" AlternatingItemStyle-BackColor="#F5F5F5" OnEditCommand="doScoreGame" OnDeleteCommand="doEditGame" OnCancelCommand="printLineup" OnItemDataBound="gridDataBound"> <Columns> <asp:TemplateColumn > <ItemTemplate> <asp:CheckBox ID="chkDelete" runat="server" /> </ItemTemplate> </asp:TemplateColumn> <asp:BoundColumn DataField="idGame" Visible="false" /> <asp:BoundColumn DataField="isClose" Visible="false" /> <asp:TemplateColumn HeaderText="Status"> <ItemTemplate> <asp:Image ID="imgStatus" runat="server" ImageUrl="~/img/icoX.png" alt="icoStatus" /> </ItemTemplate> </asp:TemplateColumn> <asp:TemplateColumn> <ItemTemplate> <asp:LinkButton ID="linkScore" runat="server" CommandName="Edit" Text="Score" /> </ItemTemplate> </asp:TemplateColumn> </Columns> </asp:DataGrid> So when i click the "linkButton", the codebehind of the userControl calls a public method in the .aspx as this: From the userControl protected void doScoreGame(object sender, DataGridCommandEventArgs e) { ((GM)this.Page).showScoring(null, null); } From the .aspx page public void showScoring(object sender, EventArgs e) { removeLastLoadedControl(); ucScoring.Visible = true; } So, here comes the problem: There are two postbacks taking place when I change the visible attribute of the ucScoring control. The first postback is fine, it's handled by the updatePanel. The second postback is a full postback, and i really don't understand why it is happening. I'm really lost here, please help! Thanks Mat

  • How can I stop Flash from changing indent when user Clicks on hyperlink in TextField?

    - by Paul Chernoch
    I have a TextField which I initialize by setting htmlText. The text has anchor tags (hyperlinks). When a user clicks on the hyperlink, the indentation of the second and subsequent lines in the paragraph changes. Why? How do I stop it? My html has an image at the beginning of the line, followed by the tag, followed by more text. To style the hyper links to look blue always and underlined when the mouse is over them, I do this: var css:StyleSheet = new StyleSheet(); css.parseCSS("a {color: #0000FF;} a:hover {text-decoration: underline;}"); stepText.styleSheet = css; stepText.htmlText = textToUse; stepText.visible = true; Here is a fragment of the html text (with newlines and exrta whitespace added to improve readability - originally it was one long line): <textformat indent="-37" blockindent="37" > <img src="media/interface/level-1-bullets/solid-circle.png" align="left" hspace="8" vspace="1"/> American Dental Association. (n.d.). <i>Cleaning your teeth and gums (oral hygiene)</i>. Retrieved 11/24/08, from <a href="http://www.ada.org/public/topics/cleaning_faq.asp" target="_blank">http://www.ada.org/public/topics/cleaning_faq.asp </a> </textformat> <br/> As it turns out, the text field is of a width such that it wraps and the second line starts with "Retrieved 11/24/08". Clicking on the hyper link causes this particular line to be indented. Subsequent paragraphs are not affected. ASIDE: The image is a list bullet about 37 pixels wide. (I used images instead of li tags because Flash does not allow nested lists, so I faked it using a series of images with varying amounts of whitespace to simulate three levels of indentation.) IDEA: I was thinking of changing all hyperlinks to use "event:" as the URL protocol, which causes a TextEvent.LINK event to be triggered instead of following the link. Then I would have to open the browser in a second call. I could use this event handler to set the html text to itself, which might clear the problem. (When I switch pages in my application and then come back to the page, everything is OKAY again.) PROBLEM: If I use the "event:" protocol and user tries the right-mouse button click, they will get an error, or so I am told. (See http://www.blog.lessrain.com/as3-texteventlink-and-contextmenu-incompatibilities/ ) I do not like this trade-off.

  • Android browser touch events stop display being updated inc. canvas/elements - How to work around?

    - by Ed Kirk
    On some android's native browser touching the page seems to stop the display from being updated until the finger is released. This occurs for both html element based animation (switching classes) and for canvas based animation. It does not however stop normal js execution and other events are fired as normal. On devices with this problem the dolphin browser also seems effected (not firefox though). Touchstart/move both have preventDefault() fired as well as stopPropergation(), cancelBubble = true; and e.returnValue = false;. In the CSS webkit selection has also been disabled. The page will not scroll. A similar question has been asked here: Does Android browser lock DOM on touchStart? but I'd like to find out if this behaviour can be overcome, or at least to discover what devices will be effected by the problem, is it a device or version android issue? If you cannot answer the question running the demo and reporting your experience along with your device model and useragent (displayed at bottom of demo page) as a comment might help others or myself answer the question. Here is a demo and steps to reproduce the behaviour. A QR code for the link can be found here https://s3-eu-west-1.amazonaws.com/canvas-test-pd/tmp.png. https://s3-eu-west-1.amazonaws.com/canvas-test-pd/index.html The web page has a canvas at the top and a div with a background image at the bottom. Every second the canvas is cleared and a different image displayed and the div has it's class switched (both toggle between 0 and 1 pngs). Once this has toggled a few times place your finger on the canvas (the top grey box) and hold it there. Wait to see if the animation continues (sometimes it will once or twice then stops) and if there are any visual distortions. Update It seems that the Galaxy Tab running 3.2 requires handlers for touchstart/end of document, not just required divs for the screen to continue updating the display. Thanks jimpic. I'm starting to believe it's an issue caused by manufacturers skins, although this is difficult to prove.

  • JavaFX2: Drag Event start and end coordinates

    - by user
    I have one node(ImageView) that displays an image and another node(rectangle) that resides on top of it. The behavior I need is that when the mouse is dragged(press-drag-release gesture) over the rectangle, both the nodes should move coherently. My thought process goes in the following direction: • Move both the nodes by the same distance in the direction of the drag. For this option(maybe there are more options) I need the distance between the start and end of the mouse drags. I tried capturing the start and end coordinates of the drag but have been unsuccessful. I think I am getting lost in which handlers to implement. The code I have is below: import javafx.event.EventHandler; import javafx.geometry.Rectangle2D; import javafx.scene.image.ImageView; import javafx.scene.input.MouseEvent; public class MyView { double mouseDragStartX; double mouseDragEndX; double mouseDragStartY; double mouseDragEndY; ImageView imageView; public MyView() { imageView = new ImageView("C:\\temp\\test.png"); } private void setRectangleEvents(final MyObject myObject) { myObject.getRectangle().setOnMousePressed(new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent mouseEvent) { mouseDragStartX = mouseEvent.getX(); mouseDragStartY = mouseEvent.getY(); mouseEvent.consume(); } }); myObject.getRectangle().setOnMouseReleased(new EventHandler<MouseEvent>() { public void handle(MouseEvent mouseEvent) { mouseDragEndX = mouseEvent.getX(); mouseDragEndY = mouseEvent.getY(); myObjectDraggedHandler(); } }); } private void myObjectDraggedHandler() { Rectangle2D viewport = this.imageView.getViewport(); double newX = this.imageView.getImage().getWidth() + (mouseDragEndX - mouseDragStartX); double newY = this.imageView.getImage().getHeight() + (mouseDragEndY - mouseDragStartY); this.imageView.setViewport(new Rectangle2D(newX, newY, viewport.getWidth(), viewport .getHeight())); } } P.S: This code is just for indicating what I am trying to implement and will not compile correctly. Or maybe my question should just have been: How to capture the length or span of a mouse drag?

  • OpenGL, how to set a monocrome texture to a colored shape?

    - by Santiago
    I'm developing on Android with OpenGL ES, I draw some cubes and I change its colors with glColor4f. Now, what I want is to give a more realistic effect on the cubes, so I create a monochromatic 8bit depth, 64x64 pixel size PNG file. I loaded on a texture, and here is my problem, witch is the way to combine the color and the texture to get a colorized and textured cubes onto the screen? I'm not an expert on OpenGL, I tried this: On create: public void asignBitmap(GL10 gl, Bitmap bitmap) { int[] textures = new int[1]; gl.glGenTextures(1, textures, 0); mTexture = textures[0]; gl.glBindTexture(GL10.GL_TEXTURE_2D, mTexture); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_NEAREST); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); gl.glTexEnvf(GL10.GL_TEXTURE_ENV, GL10.GL_TEXTURE_ENV_MODE, GL10.GL_REPLACE); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, GL10.GL_ALPHA, bitmap, 0); ByteBuffer tbb = ByteBuffer.allocateDirect(texCoords.length * 4); tbb.order(ByteOrder.nativeOrder()); mTexBuffer = tbb.asFloatBuffer(); for (int i = 0; i < 48; i++) mTexBuffer.put(texCoords[i]); mTexBuffer.position(0); } And OnDraw: public void draw(GL10 gl, int alphawires) { gl.glColor4f(1.0f, 0.0f, 0.0f, 0.5f); //RED gl.glBindTexture(GL10.GL_TEXTURE_2D, mTexture); gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA); gl.glEnable(GL10.GL_TEXTURE_2D); gl.glEnable(GL10.GL_BLEND); gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY); gl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, mTexBuffer); //Set the face rotation gl.glFrontFace(GL10.GL_CW); //Point to our buffers gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertexBuffer); //Enable the vertex and color state gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); //Draw the vertices as triangles, based on the Index Buffer information gl.glDrawElements(GL10.GL_TRIANGLES, 36, GL10.GL_UNSIGNED_BYTE, indexBuffer); //Disable the client state before leaving gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY); gl.glDisable(GL10.GL_BLEND); gl.glDisable(GL10.GL_TEXTURE_2D); } I'm even not sure if I have to use a blend option, because I don't need transparency, but is a plus :) Thank's

  • Navbar Menu Trouble shoot

    - by Nabeel M
    So I wanted to create the fixed nav bar on top of the page. Instead of creating nav bar with ordered list, I used the following approach: <header> <div class="nav"> <img src="images/logo_ab.png" alt="AurinBioTech Logo"/> <a href="index.html">Home</a> <a href="#">About</a> <a href="#">Team</a> <a href="#">Science</a> <a href="#">Need</a> <a href="#">Pipeline</a> <a href="#">Contact</a> </div> </header> CSS: header .nav { margin-top:100px; width:100%; height:10%; text-align:center; padding-top:2%; margin:0 auto; position:fixed; top:0; } header .nav a { font-size: 2em; padding-left: 15px; padding-right: 15px; color:rgb(1, 1, 1); text-decoration: none; font-family: 'Bebas'; } header .nav a:hover { color:white; background-color: #404040; border-radius:5px; padding:0 auto; } header .nav a:active{ background-color: #404040; border-radius:5px; text-decoration:overline; } header .nav img { width:260px; height:65px; padding-right:4em; } The reason I used this approach is because I wanted to use logo image next to the nav bar so it would align properly in the same line. Now the problem is that I need to add sub-menus under Science and Pipeline heading. Since I didn't use UL or LI, how can I add sub-menus under those heading. OR, can you tell me any other way to create a NAV bar that shows the logo as well. so it would be LOGO and MENUS on the same line. Great thanks in advance.

  • CGAffineTransformMakeRotation goes the other way after 180 degrees (-3.14)

    - by TheKillerDev
    So, i am trying to do a very simple disc rotation (2d), according to the user touch on it, just like a DJ or something. It is working, but there is a problem, after certain amount of rotation, it starts going backwards, this amount is after 180 degrees or as i saw in while logging the angle, -3.14 (pi). I was wondering, how can i achieve a infinite loop, i mean, the user can keep rotating and rotating to any side, just sliding his finger? Also a second question is, is there any way to speed up the rotation? Here is my code right now: #import <UIKit/UIKit.h> @interface Draggable : UIImageView { CGPoint firstLoc; UILabel * fred; double angle; } @property (assign) CGPoint firstLoc; @property (retain) UILabel * fred; @end @implementation Draggable @synthesize fred, firstLoc; - (id)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; angle = 0; if (self) { // Initialization code } return self; } -(void)handleObject:(NSSet *)touches withEvent:(UIEvent *)event isLast:(BOOL)lst { UITouch *touch =[[[event allTouches] allObjects] lastObject]; CGPoint curLoc = [touch locationInView:self]; float fromAngle = atan2( firstLoc.y-self.center.y, firstLoc.x-self.center.x ); float toAngle = atan2( curLoc.y-(self.center.y+10), curLoc.x-(self.center.x+10)); float newAngle = angle + (toAngle - fromAngle); NSLog(@"%f",newAngle); CGAffineTransform cgaRotate = CGAffineTransformMakeRotation(newAngle); self.transform = cgaRotate; if (lst) angle = newAngle; } -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch =[[[event allTouches] allObjects] lastObject]; firstLoc = [touch locationInView:self]; }; -(void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [self handleObject:touches withEvent:event isLast:NO]; }; -(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { [self handleObject:touches withEvent:event isLast:YES]; } @end And in the ViewController: UIImage *tmpImage = [UIImage imageNamed:@"theDisc.png"]; CGRect cellRectangle; cellRectangle = CGRectMake(-1,self.view.frame.size.height,tmpImage.size.width ,tmpImage.size.height ); dragger = [[Draggable alloc] initWithFrame:cellRectangle]; [dragger setImage:tmpImage]; [dragger setUserInteractionEnabled:YES]; dragger.layer.anchorPoint = CGPointMake(.5,.5); [self.view addSubview:dragger]; I am open to new/cleaner/more correct ways of doing this too. Thanks in advance.

  • Make text in a <div> wrap around a child element.

    - by John
    In Word you can place an image on a page and have the text flow nicely around it. I was wondering how far one can get towards this using CSS, noting that is has to work in IE6. I already have something sort of close using float, but the floated child-element still 'blocks' text above it. So it partially wraps. Is it possible to put a child div at some arbitrary position in the parent, and have text flow around it freely? The actual use-case here is to put illustrations inside the main content , where each illustration is implemented inside a child . I repeat, it has to work on IE6. And I don't want to get too involved in browser-specific hacks... floating the child at least works on IE6 with no tweaking. Currently I have like this: <div> <div class="illustration"> <img src="image1.png" /> <p>Illustration caption</p> </div> <p>Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. Atvero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet. </p> </div> div.illustration { float:right; border-top: 1px solid #505050; border-left: 1px solid #505050; border-right: 1px solid #505050; border-bottom: 1px solid #505050; margin-right:30px; margin-top:100px; text-align:center; padding:2px; background: #96C3FF; } div.illustration p { margin:0; font-size:small; font-style:italic; padding:0; }

  • How to know there is something in the cell or not ?

  • Using images in QListWidget, is this possible?

    - by Neko
    Hi, again. :) As with the last few times I posted here, I have a question about QT, which I am using to create a chat messenger client. To display the list of online users, I'm using a QListWidget, as created like this: listWidget = new QListWidget(horizontalLayoutWidget); listWidget->setObjectName("userList"); QSizePolicy sizePolicy1(QSizePolicy::Preferred, QSizePolicy::Expanding); sizePolicy1.setHorizontalStretch(0); sizePolicy1.setVerticalStretch(0); sizePolicy1.setHeightForWidth(listWidget->sizePolicy().hasHeightForWidth()); listWidget->setSizePolicy(sizePolicy1); listWidget->setMinimumSize(QSize(30, 0)); listWidget->setMaximumSize(QSize(150, 16777215)); listWidget->setBaseSize(QSize(100, 0)); listWidget->setContextMenuPolicy(Qt::CustomContextMenu); Users are shown by constantly refreshing the list, like this: (Note: There are different channels, with different userlists, so refreshing it is the most efficient thing to do, as far as I know.) void FMessenger::refreshUserlist() { if (currentPanel == 0) return; listWidget = this->findChild<QListWidget *>(QString("userList")); listWidget->clear(); QList<FCharacter*> charList = currentPanel->charList(); QListWidgetItem* charitem = 0; FCharacter* character; foreach(character, charList) { charitem = new QListWidgetItem(character->name()); // charitem->setIcon(QIcon(":/Images/status.png")); listWidget->addItem(charitem); } } This has always worked perfectly. The line that I commented out is the one I have problems with: my current goal is to be able to display a user's online status with an image, which represents whether they are busy, away, available, etc. Using setIcon() does absolutely nothing though, apparently; the items still show up as they used to, without icons. I'm aware that this is probably not the way this function needs to be used, but I have found little documentation about it online, and absolutely no useful examples of implementations. My question is, can anybody help me with fixing this problem? Any help would be appreciated terrifically, like always!

  • How to add Items to GridView in C# Windows Store App (Win8)

    - by flexage
    To keep things simple let's just say I have a c# Windows Store Project for Windows 8 that has the following items: GridView (PlatformsGrid) List«PlatformSearchResult» (allPlatforms) DataTemplate (PlatformDataTemplate) in standardstyles.xaml allPlatforms is a collection of "PlatformSearchResult"objects populated from an online API, and has the following 3 properties: ID Name Alias I am able to add a new item to the gridview for each object that exists in my allPlatforms collection, however the items are blank and do not show the data from my objects. A quick summary of the current code looks like this: XAML Markup: <!-- Platforms Content --> <GridView x:Name="PlatformsGrid" Grid.Row="1" CanReorderItems="True" CanDragItems="True" ItemTemplate="{StaticResource PlatformDataTemplate}" > <GridView.ItemsPanel> <ItemsPanelTemplate> <WrapGrid MaximumRowsOrColumns="2" VerticalChildrenAlignment="Top" HorizontalChildrenAlignment="Center" /> </ItemsPanelTemplate> </GridView.ItemsPanel> </GridView> Data Template <!-- Platform Item Template --> <DataTemplate x:Key="PlatformDataTemplate"> <Grid Background="#FF939598" Height="250" Width="250"> <Image Source="/SampleImage.png" Stretch="UniformToFill"/> <StackPanel Orientation="Vertical" Background="#CC000000" Height="90" VerticalAlignment="Bottom"> <TextBlock Text="{Binding Name}" Margin="10,3,0,0" Width="242" Height="62" TextTrimming="WordEllipsis" TextWrapping="Wrap" HorizontalAlignment="Left"/> <TextBlock Text="{Binding Alias}" Margin="10,2,0,0" Width="186" Height="14" TextTrimming="WordEllipsis" HorizontalAlignment="Left" FontSize="9" Opacity="0.49"/> </StackPanel> </Grid> </DataTemplate> Controlling Function private async void FetchItemInfo_Loaded(object sender, RoutedEventArgs e) { // Get List of Top Games List<PlatformSearchResult> allPlatforms = new List<PlatformSearchResult>(); allPlatforms = await GamesDB.GetPlatforms(); // Dynamically Create Platform Tiles foreach (PlatformSearchResult platform in allPlatforms) { PlatformsGrid.DataContext = platform; PlatformsGrid.Items.Add(platform); } } How do I get the added items to show the appropriate object properties (ignoring the image for now), I'm just interested in populating the content of the TextBlocks. I appreciate any help anyone can provide! Thanks, Alex.

  • proper fill an image larger than screen

    - by madcat
    what I wanted to achieve here is simply fit the image width to the screen on both orientations and use UIScrollView to just allow scroll vertically to see the whole image. both viewController and view are created pragmatically. the image loaded is larger than screen on both width and height. here is the related code in my viewController: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } - (void)loadView { UIScreen *screen = [UIScreen mainScreen]; CGRect rect = [screen applicationFrame]; self.view = [[UIView alloc] initWithFrame:rect]; self.view.contentMode = UIViewContentModeScaleAspectFill; self.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; UIImage *img=[[UIImage alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"image" ofType:@"png"]]; UIImageView *imgView =[[UIImageView alloc] initWithImage:img]; [img release]; imgView.contentMode = UIViewContentModeScaleAspectFill; imgView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; [self.view addSubview:imgView]; [imgView release]; } tried all combinations for both contentMode above, did not give me correct result. the most close I am getting now: I manually resize imgView in loadView, portrait mode would display correctly since app always starts with portrait mode, but in landscape mode, the width fits correctly, but image is centered vertically rather than top aligned. if I add the imgView to a scrollView, in landscape mode it looks like contentSize is not set to full image size. but when I scroll bounce I can see the image is there in full size. question: why I need to resize it manually? in landscape mode how and where I can 'move' the imgView, so imgView.frame.origin is (0,0) and works correctly with a scroll view? Thanks! UPDATE: I added: imgView.clipsToBounds = YES; and find out in landscape mode the image bounds is smaller than screen in height. so the question becomes how to have the image view keeps original ratio (thus shows the full image always) when rotated to landscape? do I need to manually resize it after rotation again?

  • How to make a pause before continuing method

    Now, I know that this has been asked, but I need to know how to do this NOT on html or anything. Heres my code, not including all of the other java files. package rtype; import java.awt.Image; import java.awt.event.KeyEvent; import java.util.ArrayList; import javax.swing.ImageIcon; public class aa { private int xd; private int yd; private int dx; private int dy; private int x; private int y; private Image image; private ArrayList missiles; private final int CRAFT_SIZE = 70; public aa() { ImageIcon ii = new ImageIcon(this.getClass().getResource("/aa.png")); image = ii.getImage(); missiles = new ArrayList(); x = 10; y = 10; xd = -14; yd = 140; } public void move() { if(y >=xd) y += dx; else if(y < xd) y += 1; if(y <=yd) y += dy; else if(y > yd) y += -1; } public int getX() { return x; } public int getY() { return y; } public Image getImage() { return image; } public ArrayList getMissiles() { return missiles; } public void keyPressed(KeyEvent e) { int key = e.getKeyCode(); if (key == KeyEvent.VK_SPACE) { fire(); } if (key == KeyEvent.VK_UP) { dy = -1; } if (key == KeyEvent.VK_DOWN) { dy = 1; } if (key == KeyEvent.VK_RIGHT) { yd++; } if (key == KeyEvent.VK_LEFT) { yd--; } if (key == KeyEvent.VK_W) { xd++; } if (key == KeyEvent.VK_S) { xd--; } } public void fire() { try{ missiles.add(new Missle(x + CRAFT_SIZE, y + CRAFT_SIZE)); }catch(Exception e){} } public void keyReleased(KeyEvent e) { int key = e.getKeyCode(); if (key == KeyEvent.VK_UP) { dy = 0; } if (key == KeyEvent.VK_DOWN) { dy = 0; } } } So, at the method, fire(), I want to make it delay between shots. HOW? sorry if this is n00bish

  • How Do I Setup the Notepad++ Run Command for Ruby?

    - by EstanislaoStan
    I'm trying to setup the Notepad++ IDE so that when I press F6 the Ruby script I'm editing will run. After searching the internet I've found that putting [cmd /K ruby "$(FULL_CURRENT_PATH)"] without the brackets into the run dialogue box that pops up when I press F5 will run basic scripts in the Command Prompt (I'm using Windows 7). However, if my code loads any external data such as .txt files, or as I've found with Gosu, loads any image files, Ruby complains that things do not exist which do in fact exist. I know my code and Ruby installation (Ruby 1.9.3) are fine because prior to now I've been using FreeRIDE, an older, somewhat buggy IDE that I've grown tired of, and my code runs fine when I press F5 using that IDE. Some examples of the complaints follow.

  • What's causing this background-image to display "incorrectly" in Opera and Firefox?

    - by Sukasa
    I know this is something I'm probably doing wrong, so please don't incinerate me for the thread title. I'm trying to put together a small personal website using HTML 5/CSS3. I've checked with the w3c validator and the site and CSS file fully conform according to the validator (However the validator has a warning attached that it might not be perfect). I'm not sure how to explain it without a picture, so here's a comparison of Chrome/Opera/Firefox: So, you can sorta see how in Chrome the background image is in one non-repeating piece, whereas in Opera/Firefox the image has, oddly, been broken up and placed slightly differently. I'm confident this is due to an error on my part, but I've had no luck at all figuring out why the image is being mangled in Opera and Firefox. Here's the CSS that's relevant to this issue: /* Content Pane */ .content { position: absolute; left: 220px; width: 800px; top: 80px; min-height: 550px; background-color: rgba(8,12,42,0.85); } /* Headers */ .content hgroup { background: url("Header_Flat.png") no-repeat left top; min-height: 38px; padding-left: 28px; text-shadow: 0 0 8px #FFA9FF; color: Black; text-decoration: none; } .content hgroup h1 { display: block; } .content hgroup h3 { display: inline; position: relative; top: -12px; left: 20px; text-shadow: 0 0 6px #AFF9FF; } .content hgroup h4 { display: inline; position: relative; top: -12px; left: 20px; font-size: xx-small; text-shadow: 0 0 6px #AFF9FF; } And the HTML: <hgroup> <h1>New Site!</h1> <h3>Now with Bloom!</h3> <h4> - Posted Tuesday, May 11th 2010</h4> </hgroup> Can anyone see what I'm doing wrong?

  • iOS dynamic object creation

    - by Abdul Ahmad
    I've worked with Xcode and iOS on a few personal projects and have always used non-object-oriented designs for everything... just because I've been doing mostly learning/experimenting with things. Now I've been trying to implement some object oriented design into one game I've made previously. The idea is, I have a space ship that can shoot bullets. In the past I basically added the UIImageView to the storyboard and then connected it to the .h file and from there did things on it like move it around or whatever (using CGPointMake). The idea now is to make a method (and a whole other class soon) that will create a UIImageView programmatically, allocate it, add it to the superview etc... I've got this working so far, easy stuff, but the next part is a bit harder. Where do I store this local variable "bullet"? I've been saving it to an NSMutableArray and doing the following: (actually here are the methods that I have) -(void)movement { for (int i = 0; i < [array1 count]; i ++) { UIImageView *a = [array1 objectAtIndex:i]; a.center = CGPointMake(a.center.x + 2, a.center.y); if (a.center.x > 500) { [array1 removeObjectAtIndex:i]; [a removeFromSuperview]; } } } -(void)getBullet { UIImageView *bullet = [[UIImageView alloc] initWithFrame:CGRectMake(ship.center.x + 20, ship.center.y - 2, 15, 3)]; bullet.image = [UIImage imageNamed:@"bullet2.png"]; bullet.hidden = NO; [self.view addSubview:bullet]; [array1 addObject:bullet]; } (by the way, array1 is declared in the .h file) and theres a timer that controls the movement method timer = [NSTimer scheduledTimerWithTimeInterval:0.5 target:self selector:@selector(movement) userInfo:nil repeats:YES]; first question is: what is the correct way of doing this? Storing a bullet for example until it is removed from the superview, should I store it another way? and another question is, when I remove a UIImageView from the superview, does that remove it from memory so its not using up system resources? Thank you for the help! (will update if I Think of other questions
