  • JPanel: both implementing my own paintComponent() and rendering children doesn't work

    - by Paul Marshall
    I'm extending a JPanel to display a game board, and adding a JEditorPane at the bottom to hold some status text. Unfortunately, the game board renders just fine, but the JEditorPane is just a blank gray area until I highlight the text in it, when it will render whatever text is highlighted (but not the rest). If I'm understanding Swing right, it should work, because super.paintComponent(g) should render the other children (i.e., the JEditorPane). Tell me, o great stackoverflow, what bonehead mistake am I making? public GameMap extends JPanel { public GameMap() { JEditorPane statusLines = new JEditorPane("text/plain","Stuff"); this.setLayout(new BoxLayout(this,BoxLayout.PAGE_AXIS)); this.add(new Box.Filler(/*enough room to draw my game board*/)); this.add(statusLines); } public void paintComponent(Graphics g){ super.paintComponent(g); for ( all rows ){ for (all columns){ //paint one tile } } } }

  • Does margin-left:2px; render faster than margin:0 0 0 2px;?

    - by Christopher Altman
    Douglas Crockford describes the consequence of Javascript inquiring a node's style. How simply asking for the margin of a div causes the browser to 'reflow' the div in the browser's rendering engine four times. So that made me wonder, during the initial rendering of a page (or in Crockford's jargon a "web scroll") is it faster to write CSS that defines only the non-zero/non-default values? To provide an example: div{ margin-left:2px; } Than div{ margin:0 0 0 2px; } I know consequence of this 'savings' is insignificant, but I think it is still important to understand how the technologies are implemented. Also, this is not a question about formatting CSS--this is a question about the implementations of browsers rendering CSS. Reference: http://developer.yahoo.com/yui/theater/video.php?v=crockonjs-4

  • Java/Swing offscreen rendering (Cobra HTMLPanel -> BufferedImage) Problem: Component doesn't finish

    - by Alterscape
    I'm trying to render the contents of a the Java/Swing Cobra HTML renderer to an offscreen BufferedImage, for use elsewhere in my app: slideViewPanel.setDocument(document, rendererContext); BufferedImage test = new BufferedImage(300,300,BufferedImage.TYPE_INT_RGB); Graphics g = test.getGraphics(); slideViewPanel.paint(g); The resulting image in g shows a partially rendered page -- sometimes the contents of the HTMLFrame before the new document was set; sometimes a half-rendered version of the new document. I gather this is because Cobra's setDocument method just schedules the document for re-rendering, but I'm stepping through in the debugger and I don't see a second thread to do re-rendering. Anyone have any insight into what might be happening here?

  • Resources for looking up differences in rendering behavior between web-browsers and browser bugs

    - by ICodeForCoffee
    I recently encountered a printing issue in Firefox that eventually turned out to be a problem with the fieldset tag we wrapped the entire page in. (Bugzilla: Bug 471015) All browsers have their own rendering quirks and issues, but it can be very hard to know what's causing different behaviors. Sure, you can Google, but that's often taking a shot in the dark about what you think is causing the problem. It also doesn't stop you from having to sort through multiple complains about the same behavior before you find someone who has the issue your looking for. Are there any websites out there that let you search for rendering behavior issues by browser version, browser function, css tag, or html tag? I've seen this SO Question, Wanted: Resource for documented Cross-Browser differences, but I'd like to find something more detailed that includes browser bugs.

  • Create a rich text control field in VBA for Word 2010

    - by mkn
    I have a control field where I dynamically add certain text. That works well so far. The problem is that in one text I have an input field where the user can type in text. I need to hardcode the form text input field into the VBA code. How is this achieved? Or can someone point me in the right direction? In the following code snippet I need to replace the [InputField] by a VBA input field. ActiveDocument.SelectContentControlsByTitle("Bottom").Item(1).Range.Text = _ "Some Text" & vbNewLine & _ "Some Text" & vbNewLine & _ "Some Text" & vbNewLine & _ "Text [InputField] Text"

  • Firefox, prevent rendering between javascript statements.

    - by Erik
    I'm trying to create some kind of zoom around the mouse cursor feature on my website which ultimately runs these two lines (+ the same for height/scrollTop). canvas.style.width = someValue; canvas.parentNode.scrollLeft = someOtherValue; The problem is that in firefox(3.6) the page is re-rendered directly after the first row has been executed and since the view is depending on both values this means that every time i recalculate the view firefox will will render an invalid view before the correct one, in other words creating flicker. I've tried swapping the two rows but get the same problem. In chrome, opera and IE this doesn't happen. Both lines are executed before any rendering is done. Is there any way to lock the rendering manually, maybe something like this? document.disableRendering(); //fantasy function canvas.style.width = someValue; canvas.parentNode.scrollLeft = someOtherValue; document.enableRendering(); //fantasy function

  • How to extract data from a text file

    - by šljaker
    I need to parse some large text file and extract Display name and area code only if it matches the following pattern: Line starts with display name (any number of words) Followed by 6 digits (can contain spaces) Followed by #text tag e.g. John doe 123 456 #text some text Display name: John doe Area code: 123 456 Test 123456 #text Display name: Test Area code: 123456 Test 123 #test Invalid, area code contains only 3 digits Test 123456 #test1 Invalid, contains invalid tag Test 123g45 #test Invalid, area code contains letters etc. I know how to open the text file and read it line by line, but having trouble with writing the regular expression. Any help would be greatly appreciated! edit: I have tried this: private static void Main(string[] args) { string text = "John Doe 123 45 #text Lorem ipsum dolor :)"; string pattern = @"(\w+)*([0-9]{2,5}).([0-9]{2,5}).#text"; Match match = Regex.Match(text, pattern, RegexOptions.IgnoreCase); if (match.Success) { string key = match.Groups[0].Value; Console.WriteLine(key); } }

  • How to stop rendering invisible faces

    - by TheMorfeus
    I am making a voxel-based game, and for needs of it, i am creating a block rendering engine. Point is, that i need to generate lots of cubes. Every time i render more than 16x16x16 chunk of theese blocks, my FPS is dropped down hardly, because it renders all 6 faces of all of theese cubes. THat's 24 576 quads, and i dont want that. So, my question is, How to stop rendering vertices(or quads) that are not visible, and therefore increase performance of my game? Here is class for rendering of a block: public void renderBlock(int posx, int posy, int posz) { try{ //t.bind(); glEnable(GL_CULL_FACE); glCullFace(GL_BACK);// or even GL_FRONT_AND_BACK */); glPushMatrix(); GL11.glTranslatef((2*posx+0.5f),(2*posy+0.5f),(2*posz+0.5f)); // Move Right 1.5 Units And Into The Screen 6.0 GL11.glRotatef(rquad,1.0f,1.0f,1.0f); glBegin(GL_QUADS); // Draw A Quad GL11.glColor3f(0.5f, 0.4f, 0.4f); // Set The Color To Green GL11.glTexCoord2f(0,0); GL11.glVertex3f( 1f, 1f,-1f); // Top Right Of The Quad (Top) GL11.glTexCoord2f(1,0); GL11.glVertex3f(-1f, 1f,-1f); // Top Left Of The Quad (Top) GL11.glTexCoord2f(1,1); GL11.glVertex3f(-1f, 1f, 1f); // Bottom Left Of The Quad (Top) GL11.glTexCoord2f(0,1); GL11.glVertex3f( 1f, 1f, 1f); // Bottom Right Of The Quad (Top) //GL11.glColor3f(1.2f,0.5f,0.9f); // Set The Color To Orange GL11.glTexCoord2f(0,0); GL11.glVertex3f( 1f,-1f, 1f); // Top Right Of The Quad (Bottom) GL11.glTexCoord2f(0,1); GL11.glVertex3f(-1f,-1f, 1f); // Top Left Of The Quad (Bottom) GL11.glTexCoord2f(1,1); GL11.glVertex3f(-1f,-1f,-1f); // Bottom Left Of The Quad (Bottom) GL11.glTexCoord2f(1,0); GL11.glVertex3f( 1f,-1f,-1f); // Bottom Right Of The Quad (Bottom) //GL11.glColor3f(1.0f,0.0f,0.0f); // Set The Color To Red GL11.glTexCoord2f(0,0); GL11.glVertex3f( 1f, 1f, 1f); // Top Right Of The Quad (Front) GL11.glTexCoord2f(1,0); GL11.glVertex3f(-1f, 1f, 1f); // Top Left Of The Quad (Front) GL11.glTexCoord2f(1,1); GL11.glVertex3f(-1f,-1f, 1f); // Bottom Left Of The Quad (Front) GL11.glTexCoord2f(0,1); GL11.glVertex3f( 1f,-1f, 1f); // Bottom Right Of The Quad (Front) //GL11.glColor3f(1f,0.5f,0.0f); // Set The Color To Yellow GL11.glTexCoord2f(0,0); GL11.glVertex3f( 1f,-1f,-1f); // Bottom Left Of The Quad (Back) GL11.glTexCoord2f(1,0); GL11.glVertex3f(-1f,-1f,-1f); // Bottom Right Of The Quad (Back) GL11.glTexCoord2f(1,1); GL11.glVertex3f(-1f, 1f,-1f); // Top Right Of The Quad (Back) GL11.glTexCoord2f(0,1); GL11.glVertex3f( 1f, 1f,-1f); // Top Left Of The Quad (Back) //GL11.glColor3f(0.0f,0.0f,0.3f); // Set The Color To Blue GL11.glTexCoord2f(0,1); GL11.glVertex3f(-1f, 1f, 1f); // Top Right Of The Quad (Left) GL11.glTexCoord2f(1,1); GL11.glVertex3f(-1f, 1f,-1f); // Top Left Of The Quad (Left) GL11.glTexCoord2f(1,0); GL11.glVertex3f(-1f,-1f,-1f); // Bottom Left Of The Quad (Left) GL11.glTexCoord2f(0,0); GL11.glVertex3f(-1f,-1f, 1f); // Bottom Right Of The Quad (Left) //GL11.glColor3f(0.5f,0.0f,0.5f); // Set The Color To Violet GL11.glTexCoord2f(0,0); GL11.glVertex3f( 1f, 1f,-1f); // Top Right Of The Quad (Right) GL11.glTexCoord2f(1,0); GL11.glVertex3f( 1f, 1f, 1f); // Top Left Of The Quad (Right) GL11.glTexCoord2f(1,1); GL11.glVertex3f( 1f,-1f, 1f); // Bottom Left Of The Quad (Right) GL11.glTexCoord2f(0,1); GL11.glVertex3f( 1f,-1f,-1f); // Bottom Right Of The Quad (Right) //rquad+=0.0001f; glEnd(); glPopMatrix(); }catch(NullPointerException t){t.printStackTrace(); System.out.println("rendering block failed");} } Here is code that renders them: private void render() { GL11.glClear(GL11.GL_COLOR_BUFFER_BIT|GL11.GL_DEPTH_BUFFER_BIT); for(int y=0; y<32; y++){ for(int x=0; x<16; x++){ for(int z=0; z<16; z++) { b.renderBlock(x, y, z); } } } }

  • Adjusting the Score on Oracle Text search results

    - by Kyle Hatlestad
    When you sort the results of a search by Score using OracleTextSearch as the search engine in WebCenter Content, the results coming back are based on the relevancy on the document.  In theory, the more relevant the search term is to the document, the higher ranked Score it should receive.  But in practice, the relevancy score can seem somewhat of a mystery.  It's not entirely clear how it ranks the importance of some documents over others based on the search term.  And often times, once a word appears a certain number of times within a document, the Score simply maxes out at 100 and the top results can be difficult to discern from one another.  Take for example the search for 'vacation' on this set of documents: Out of 7 results, 6 of them have a Score of '100' which means they are basically ranked the same.  This doesn't make the sort by Score very meaningful.   Besides sorting by relevance, you can also tell Oracle Text to sort by occurrence.  In that case, it is a much more predictable result in how they would be ranked. And for many cases provide a more meaningful sorting of results then relevance. To change this takes a small component change to the SearchOperatorMap resource.  By default, the query used for full-text searching looks like: <td>(ORACLETEXTSEARCH)fullText</td> <td>DEFINESCORE((%V), RELEVANCE * .1)</td> <td>text</td> Overriding this resource and changing it to: <td>(ORACLETEXTSEARCH)fullText</td> <td>DEFINESCORE((%V), OCCURRENCE * .01)</td>  <td>text</td> will force it to now use occurrence (note the change in scale to .01 as well).  So running the same search and sort options as the example above, the results come out quite a bit differently: In this case, there is a clear understanding of how the items rank.   And generally, if the search term appears 3 times more in one document then another, it's got a better chance of being a document I'm interested in.  You may or may not feel the relevance ranking is better then the search term occurrence, but this provides the opportunity to try an alternate method that might work better for your results.  A pre-built component is available for download here. There is one caveat in using this method.  The occurrence ranking also maxes out at 100, so if a search term is in the document more then that, the Score result will stay at 100.

But now i am wondering how to program/create fonts for game (2D), or how to simple draw variable text to output with Direct3D? (it is not as SharpDX question as common Direct3D question, how to start with game GUIs? And what should i do to program simple GUI's like menu for a game (generally i understand that it's shaders).

  • Conditional Gridview Text - Checkboxes

    This code sample shows how to either show or make invisible, a checkbox in each row of the Gridview, along with making text conditional, based on certain criteria. In this case, if the Postal code starts with a non-numeric character, we change it to "Alt Text", and we set the Visible property of the checkbox in that row to "False"

  • White text on yellow background in popup elements with Ambiance theme

    - by texnic
    In Eric4, when I select the "What's This" tool and then click on something to get a pop-up explanation, the resulting text appears white on yellow (unreadable). The tool-tips are fine (white on black). If I change the theme to any other, the text is black on yellow. I've found some posts on the internet about such behaviour with Skype and LibreOffice, but it doesn't seem to me to be the program-specific problem since it appears in various apps. How can I tune it?

  • SSIS Expression to Find Text Between Characters

    - by Compudicted
    It will be a super short and looks like the first and last post in January 2011. So back to the topic, I decided to share an SSIS expression I crafted to extract the value concealed between two characters (I needed to get a portion of text in a file path): Substring(@[User::MyString],FINDSTRING(@[User::MyString],"(",1)+1,FINDSTRING(@[User::MyString],")",1) - FINDSTRING(@[User::MyString],"(",1)-1) The value of MyString say could be c:\test\test(testing123456789).txt, then the resulting text captured testing123456789. Hopefully it will be needed to somebody.

  • Text Classification Implementation

    - by Hearty
    I've been trying to implement a text classification system. It needs to read a text file, and extract the words and the word frequency. So far, I've been planning to parse the words, put them in a dictionary and save it to an XML file. I am using C++/CLI. Is this a good implementation or is there a simpler or better implementation? May be related question (some code implementation): http://stackoverflow.com/questions/10631309/save-dictionary-to-xml-file

Do you know where I can find this kind of licence text ?

  • Gmail and FB is not rendering properly in Firefox

    - by Andy
    I am unable read Gmail in my Firefox browser on my laptop. However, there are no problems when I try to access Gmail on my office desktop. In fact, Gmail renders fine on IE on both computers. Things I have tried: Uninstalling and reinstalling Firefox. Using Firefox 3.6.26 and Firefox 10; same problem. Clearing the cache. But all to no avail. For starters: My background image does not get loaded. It says "Oops. Your selected image failed to load". The buttons for the new look do not get rendered, but when I do a mouse-over I see text which helps me navigate. When I try to read a message, I see the subject line and I see the reply / forward box. The message body does not get rendered, it seems like a styling error. Check this screenshot where the icons in the GMail new look are not rendered properly Check this screenshot where even facebook is not getting rendered properly EDIT: 25th Feb 2012 GMAIL is getting rendered fine in the old look

  • VS2010 Text Editor: How do I set the default formatting style for inline code blocks?

    - by nukefusion
    I've got a problem with the formatting of inline code blocks within the VS2010 text editor and wonder if anyone else has had similar problems and found the 'magic' setting I'm looking for. I'm working my way through tutorials in an MVC book. Whenever I add some inline code blocks to a view I want them formatted like so: <% foreach (var link in Model) { %> <a href="<%=Url.RouteUrl(link.RouteValues)%>"> <%=link.Text%> </a> <% } %> What I'm actually getting is this (auto-formatted by the IDE when I finish writing the code): <% foreach (var link in Model) { %> <a href="<%=Url.RouteUrl(link.RouteValues)%>"> <%=link.Text%> </a> <% } %> It's pretty irritating. Any ideas on how I can instruct the IDE to leave my <% % tags alone? I've been fiddling with options under "Tools - Options - Text Editor" for ages but alas am getting nowhere...
