  • Issue binding Image Source dependency property

    - by Archana R
    Hello, I have created a custom control for ImageButton as <Style TargetType="{x:Type Button}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Local:ImageButton}"> <StackPanel Height="Auto" Orientation="Horizontal"> <Image Margin="0,0,3,0" Source="{Binding ImageSource}" /> <TextBlock Text="{TemplateBinding Content}" /> </StackPanel> </ControlTemplate> </Setter.Value> </Setter> </Style> ImageButton class looks like public class ImageButton : Button { public ImageButton() : base() { } public ImageSource ImageSource { get { return base.GetValue(ImageSourceProperty) as ImageSource; } set { base.SetValue(ImageSourceProperty, value); } } public static readonly DependencyProperty ImageSourceProperty = DependencyProperty.Register("Source", typeof(ImageSource), typeof(ImageButton)); } However I'm not able to bind the ImageSource to the image as: (This code is in UI Folder and image is in Resource folder) <Local:ImageButton x:Name="buttonBrowse1" Width="100" Margin="10,0,10,0" Content="Browse ..."

  • How can I mix SVG and HTML into a page?

    - by John Duff
    I've been using the jQuery.svg plugin to do some SVG rendering and it works perfectly but I also want to have the server render some SVG into the page and I can't get that to work. How do I add some SVG like below into the page so that Firefox will render it? <svg xmlns="http://www.w3.org/2000/svg" version="1.1" preserveAspectRatio="none" viewBox="0 0 100 100"> <linearGradient id="background_gradient_black" x1="0%" y1="10" x2="0%" y2="90" gradientUnits="userSpaceOnUse"> <stop offset="0%" stop-color="#000" stop-opacity="1" /> <stop offset="45%" stop-color="#444" stop-opacity="1" /> <stop offset="55%" stop-color="#444" stop-opacity="1" /> <stop offset="100%" stop-color="#000" stop-opacity="1" /> </linearGradient> <rect x="0" y="0" width="100" height="100" fill="url(#background_gradient_black)"" /> </svg> Do I need a meta tag saying that there is SVG content in the page or define the SVG namespace somehow?

  • jQuery modal dialog on ajaxStart event

    - by bdl
    I'm trying to use a jQuery UI modal dialog as a loading indicator via the ajaxStart, ajaxStop / ajaxComplete events. When the page fires, an Ajax handler loads some data, and the modal dialog shows just fine. However, it never hides or closes the dialog when the Ajax event is complete. It's a very small bit of code from the local server that is returned, so the actual Ajax event is very quick. Here's my actual code for the modal div: $("#modalwindow").dialog({ modal: true, height: 50, width: 200, zIndex: 999, resizable: false, title: "Please wait..." }) .bind("ajaxStart", function(){ $(this).show(); }) .bind("ajaxStop", function(){ $(this).hide(); }); The Ajax event is just a plain vanilla $.ajax({}) GET method call. Based on some searching here and Google, I've tried altering the ajaxStop handler to use $("#modalwindow").close(), $("#modalwindow").destroy(), etc. (#modalwindow referred to here as to give explicit context). I've also tried using the standard $("#modalwindow").dialog({}).ajaxStart(... as well. Should I be binding the events to a different object? Or calling them from within the $.ajax() complete event? I should mention, I'm testing on the latest IE8, FF 3.6 and Chrome. All have the same / effect.

  • XSLT creating a table with varying amount of columns

    - by H4mm3rHead
    Hi, I have a RSS feed i need to display in a table (its clothes from a webshop system). The images in the RSS vary in width and height and I want to make a table that shows them all. First off i would be happy just to show all of the items in 3 columns, but further down the road i need to be able to specify through a parameter the amount of columns in my table. I run into a problem showing the tr tag, and making it right, this is my Code so far: <xsl:template match="item"> <xsl:choose> <xsl:when test="position() mod 3 = 0 or position()=1"> <tr> <td> <xsl:value-of select="title"/> </td> </tr> </xsl:when> <xsl:otherwise> <td> <xsl:value-of select="title"/> </td> </xsl:otherwise> </xsl:choose> </xsl:template> In RSS all "item" tags are on the same level in the xml, and thus far i need only the title shows. Thr problem seems to be that i need to specify the start tag as well as the end tag of the tr element, and cant get all 3 elements into it, anyone know how to do this?

  • How can I change the visibility of elements inside a DataTemplate when a row is selected in a Silver

    - by miketrash
    I'm using the MVVM pattern. I've bound my items and I want to only show the edit button when a row is selected in the datagrid. It appears to be possible with triggers in WPF but we don't have triggers in Silverlight. I tried a TemplatedParent binding but I'm not sure what the TemplatedParent is in this case. We don't have RelativeSource ancestor in Silverlight either. At this point I'm going to look at a solution using the code behind... <data:DataGrid.Columns> <data:DataGridTemplateColumn IsReadOnly="True" Header="Name" Width="300"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <Grid> <TextBlock x:Name="textBlock" Text="{Binding Name, Mode=OneWay}" VerticalAlignment="Center" Margin="4,4,0,4"/> <Button Margin="1,1,4,1" HorizontalAlignment="Right" VerticalAlignment="Center" Padding="7,4" Content="Edit" /> </Grid> </DataTemplate> </data:DataGridTemplateColumn.CellTemplate> </data:DataGridTemplateColumn> </data:DataGrid.Columns>

  • Scrolling list items in wpf

    - by sudarsanyes
    I guess the following picture depicts the problem better than texts... That is what I need. <ListBox x:Name="NamesListBox" ItemsSource="{Binding}"> <ListBox.ItemsPanel> <ItemsPanelTemplate> <WrapPanel x:Name="ItemWrapPanel"> <WrapPanel.RenderTransform> <TranslateTransform x:Name="ItemWrapPanelTransformation" X="0" /> </WrapPanel.RenderTransform> <WrapPanel.Triggers> <EventTrigger RoutedEvent="WrapPanel.Loaded"> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetName="ItemWrapPanelTransformation" Storyboard.TargetProperty="X" To="-1000" From="{Binding ElementName=ScrollingListItemsWindow, Path=Width}" Duration="0:0:9" RepeatBehavior="100" /> </Storyboard> </BeginStoryboard> </EventTrigger> </WrapPanel.Triggers> </WrapPanel> </ItemsPanelTemplate> </ListBox.ItemsPanel> <ListBox.ItemTemplate> <DataTemplate> <Grid> <Label Content="{Binding}" /> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox> is what I did. But here I don't wanna hard code -1000 for the X value, rather I want to determine this based on the length of the wrap panel/number of items. Can somebody help me with this ?? Reason why I choose list box is that the number of items can increase and decrease at any time and suits the problem better. If you have got any other idea, please suggest it too. Thanks.

  • How do you parse with SAX using Attributes & Values to a URL path using iPhone SDK?

    - by Jim
    I'm trying to get my head around parsing with SAX and thought a good place to start was the TopSongs example found at the iPhone Dev Center. I get most of it but when it comes to reaching Attributes and Values within a node I can't find a good example anywhere. The XML has a path to a URL for the coverArt. And the XML node looks like this. <itms:coverArt height="60" width="60">http://a1.phobos.apple.com/us/r1000/026/Music/aa/aa/27/mzi.pbxnbfvw.60x60-50.jpg</itms:coverArt> What I've tried is this for the startElement… ((prefix != NULL && !strncmp((const char *)prefix, kName_Itms, kLength_Itms)) && (!strncmp((const char *)localname, kName_CoverArt, kLength_Item) && !strncmp((const char *)attributes, kAttributeName_CoverArt, kAttributeLength_CoverArt) && !strncmp((const char *)attributes, kValueName_CoverArt, kValueLength_CoverArt) || !strncmp((const char *)localname, kName_Artist, kLength_Artist) || and picking it up again with just the localname at the end like this. if (!strncmp((const char *)localname, kName_CoverArt, kLength_CoverArt)) { importer.currentSong.coverArt = [NSURL URLWithString:importer.currentString]; The trace is -[Song setCoverArt:]: unrecognized selector sent to instance.

  • Facebook Like Meta Tags not showing Images

    - by Hooman Ahmadi
    I have implemented the Facebook Like button on all our pages and it works properly by posting to Facebook with the correct meta tags. However, the images do not show in Facebook. The image meta tags show up properly when I use the Facebook Linter, but they don't show on someone's facebook page where the Like is posted on their wall. Also, is there any way to have the info recache more often? The tags take forever to update. Our site is built with CakePHP. Below are snippets of my code, thanks: <html xmlns="http://www.w3.org/1999/xhtml" xmlns:og="http://ogp.me/ns#" xmlns:fb="http://www.facebook.com/2008/fbml"> <head> <script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script> <script type="text/javascript" src="http://use.typekit.com/wlx8xgm.js"></script> <script type="text/javascript">try{Typekit.load();}catch(e){}</script> <?php if(!isset($meta_title)) { $meta_title = $title_for_layout; } if(!isset($meta_location)) { $meta_location = null; } if(!isset($meta_image)) { $meta_image = null; } if(!isset($meta_type)) { $meta_type = null; } ?> <meta property="og:title" content="<?= $meta_title ?>"/> <meta property="og:type" content="<?= $meta_type ?>"/> <meta property="og:url" content="<?= $meta_location ?>"/> <meta property="og:image" content="<?= $meta_image ?>"/> <meta property="fb:admins" content="1004432800"/> ... echo '<br><br><fb:like href="' . $fbook_url .

  • 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.

  • Unit testing that an event is raised in C#, using reflection

    - by Thomas
    I want to test that setting a certain property (or more generally, executing some code) raises a certain event on my object. In that respect my problem is similar to http://stackoverflow.com/questions/248989/unit-testing-that-an-event-is-raised-in-c, but I need a lot of these tests and I hate boilerplate. So I'm looking for a more general solution, using reflection. Ideally, I would like to do something like this: [TestMethod] public void TestWidth() { MyClass myObject = new MyClass(); AssertRaisesEvent(() => { myObject.Width = 42; }, myObject, "WidthChanged"); } For the implementation of the AssertRaisesEvent, I've come this far: private void AssertRaisesEvent(Action action, object obj, string eventName) { EventInfo eventInfo = obj.GetType().GetEvent(eventName); int raisedCount = 0; Action incrementer = () => { ++raisedCount; }; Delegate handler = /* what goes here? */; eventInfo.AddEventHandler(obj, handler); action.Invoke(); eventInfo.RemoveEventHandler(obj, handler); Assert.AreEqual(1, raisedCount); } As you can see, my problem lies in creating a Delegate of the appropriate type for this event. The delegate should do nothing except invoke incrementer. Because of all the syntactic syrup in C#, my notion of how delegates and events really work is a bit hazy. How to do this?

  • 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!! :)

  • Dynamically add items to Tkinter Canvas

    - by nick369
    I'm attempting to learn Tkinter with the goal of being able to create a 'real-time' scope to plot data. As a test, I'm trying to draw a polygon on the canvas every time the 'draw' button is pressed. The triangle position is randomized. I have two problems: There is a triangle on the canvas as soon as the program starts, why and how do I fix this? It doesn't draw any triangles when I press the button, at least none that I can see.

I've successfully divided the image into pages and displayed them in the correct order. Each "page" is drawn within the marginbounds. (That is, each page is sized to be the same as the marginBounds.) The problem I have is that the image the page represents exceeds the bottom margin. However if I draw a rectangle with the same dimensions as the image, at the same position as the image, the rectangle matches the marginbounds. Thus when drawn to the page (in print preview and printed page) the image is larger than a rectangle drawn based on the image dimensions. I.e. The image is drawn at the same size as e.MarignBounds and is drawn at e.MarginBounds.Location yet exceeds the bottom margin. How is this? I've checked resoutions at each step of the process and they are all 96DPI. //... private List<Image> m_printImages = new List<Image>(); //... private void ImagePrintDocument_PrintPage(object sender, PrintPageEventArgs e) { PrepareImageForPrinting(e); e.Graphics.DrawImage(m_printImages[m_currentPage], new Point(e.MarginBounds.X, e.MarginBounds.Y); e.Graphics.DrawRectangle(new Pen(Color.Blue, 1.0F), new Rectangle( new Point(e.MarginBounds.X, e.MarginBounds.Y), new Size(m_printImages[m_currentPage].Width, m_printImages[m_currentPage].Height))); //rest of handler } PS Not able to show an image as free image hosting blocked here.

  • qtruby, QUiLoader and respond_to?

    - by Tim Sylvester
    I'm writing a simple Qt4 application in Ruby (using qtruby) to teach myself both. Mostly it has gone well, but in trying to use Ruby's "duck typing" I've run into a snag; respond_to? doesn't seem to reflect reality. irb(main):001:0> require 'rubygems' => true irb(main):002:0> require 'Qt4' => true irb(main):003:0> require 'qtuitools' => true irb(main):004:0> Qt::Application.new(ARGV) => #<Qt::Application:0xc3c9a08 objectName="ruby"> irb(main):005:0> file = Qt::File.new("dlg.ui") { open(Qt::File::ReadOnly) } => #<Qt::File:0xc2e1748 objectName=""> irb(main):006:0> obj = Qt::UiLoader.new().load(file, nil) => #<Qt::Dialog:0xc2bf650 objectName="dlg", x=0, y=0, width=283, height=244> irb(main):007:0> obj.respond_to?('children') => false irb(main):008:0> obj.respond_to?(:children) => false irb(main):009:0> obj.children => [#<Qt::FormInternal::TranslationWatcher:0xc2a1980 objectName="">, ... As you can see, when I check to ensure that the object I get back from loading the UI file has a children accessor I get false. If call that accessor, however, I get an array rather than a NoMethodError. So, is this a bug or have I incorrectly understood respond_to?? This looks like the problem described here, but I thought I would get an expert opinion before filing a bug against the project.

  • Disable Eclipse warning about generated html?

    - by Chadwick
    When developing Flex projects, Eclipse gives warnings about the default index.html file generated by Flex Builder. The file is in the 'target' folder (or "generated artifacts" folder. Yes, I'm also using Maven). Can I eliminate or disable this warning? The code which generates the warning is below, though I would definitely prefer not changing the html - as I say this is the template suggested by Adobe. Eclipse warns of "Undefined attribute name (xxx)" for scroll on the body tag, and most of the embed attributes. There is no DOCTYPE declaration in the html file. <html lang="en"> ... <body scroll="no"> ... <embed src="myswf.swf" quality="high" bgcolor="#869ca7" width="100%" height="100%" name="myswf-flex" align="middle" play="true" loop="false" quality="high" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/go/getflashplayer"> </embed> ...
