  • Are there any .net classes/functions that are optimized for multiple cores?

    - by diamandiev
    I know that the developer is supposed to do this himself. But seeing how we are getting cpu's with more and more cores and there are still many developers who do not use multithreading, if we have this functionality built in, it could increase performance dramatically in some scenarios. One particular example where this could be quite useful is in image processing. I doubt that the built in GDI+ classes are multithreaded.

  • 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?

  • how can I change top-margin the right way if multiple css class assigned?

    - by Radek
    I assigned these classes menu second_menu menu_about_author to ul so the html code looks like <ul class="menu second_menu menu_about_author"> I wanted this ul to have the same properties like menu and second_menu and then I wanted to move the menu_about_author little bit down. I did so by .menu_about_author { margin-top:40px; } but it didn't work any idea why the margin-top:40px; is crossed? the link to the image is [1]: http://img153.imageshack.us/img153/882/58daeef0c3c846e4a8d6321.png

    - by danbystrom
    I guess the title contains my whole question. How can I draw a string onto an image in Flash and .NET/GDI+ respectively and gain the same result? (I'm not a Flash programmer myself and it is rather hard to find out about what kind of unit Flash uses by googling for something like "flash font size"...) Ekeforshus

  • Custom cell in list in Flash AS3

    - by Stian Flatby
    I am no expert in Flash, and I need some quick help here, without needing to learn everything from scratch. Short story, I have to make a list where each cell contains an image, two labels, and a button. List/Cell example: img - label - label - button img - label - label - button As a Java-programmer, I have tried to quicly learn the syntax and visualness of Flash and AS3, but with no luck so far. I have fairly understood the basics of movie clips etc. I saw a tutorial on how to add a list, and add some text to it. So I dragged in a list, and in the code went list.addItem({label:"hello"}); , and that worked ofc. So i thought if I double-clicked the MC of the list, i would get to tweak some things. In there I have been wandering around different halls of cell-renderers etc. I have now come to the point that I entered the CellRenderer_skinUp or something, and customized it to my liking. When this was done, I expected i could use list.addItem(); and get an empty "version" of my cell, with the img, labels and the button. But AS3 expects an input in addItem. From my object-oriented view, I am thinking that i have to create an object of the cell i have made, but i have no luck reaching it.. I tried to go var test:CellRenderer = list.listItem; list.addItem(test); ..But with no luck. This is just for funsies, but I really want to make this work, however not so much that I am willing to read up on ALOT of Flash and AS3. I felt that I was closing in on the prize, but the compiler expected a semicolon after the variable (list.addItem({test:something});). Note: If possible, I do NOT want this: list.addItem({image:"src",label:"text",label"text",button:"text"}); Well.. It actually is what I want, but I would really like to custom-draw everything. Does anyone get what I am trying to do, and has any answers for me? Am I approaching this the wrong way? I have searched the interwebs for custom list-cells, but with no luck. Please, any guiding here is appreciated! Sti

  • [Flex] Caching canvas into ByteArray

    - by Eugene
    Task: (all in code, not visual) create a canvas, place into it some labels and draw some lines, then cache it as byteArray. The problem is that if I cache an object that is already drawed on the screen, it works great, but if I cache a canvas, that have been created few lines earlier, this results white image. Is there any solution to cache a display object, that was created in code, but not intended to be displayed at all?
