Hallo!

Hier mal ein kleines Beispiel zur Erstellung von Screenshots der Oberflaeche einer
SWT Anwendung anhand einer Eclipse-Action.

Code java:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74

package de.tutorials.eclipse.screencapture.actions;   import org.eclipse.jface.action.IAction; import org.eclipse.jface.dialogs.MessageDialog; import org.eclipse.jface.viewers.ISelection; import org.eclipse.swt.SWT; import org.eclipse.swt.graphics.GC; import org.eclipse.swt.graphics.Image; import org.eclipse.swt.graphics.ImageData; import org.eclipse.swt.graphics.ImageLoader; import org.eclipse.swt.graphics.Rectangle; import org.eclipse.swt.widgets.Display; import org.eclipse.ui.IWorkbenchWindow; import org.eclipse.ui.IWorkbenchWindowActionDelegate;   public class CreateScreenShotAction implements IWorkbenchWindowActionDelegate {     private IWorkbenchWindow window;     /**      * The constructor.      */     public CreateScreenShotAction() {     }       /**      * The action has been activated. The argument of the      * method represents the 'real' action sitting      * in the workbench UI.      * @see IWorkbenchWindowActionDelegate#run      */     public void run(IAction action) {         final Display display = Display.getDefault();         Rectangle rectangle = display.getBounds();         Image image = new Image(display,rectangle.width,rectangle.height);         GC gc = new GC(display);         gc.copyArea(image, 0,0);         ImageLoader imageLoader = new ImageLoader();         imageLoader.data = new ImageData[]{image.getImageData()};         imageLoader.save("c:/screenShot.jpg", SWT.IMAGE_JPEG);         image.dispose();         gc.dispose();                 MessageDialog.openInformation(                 window.getShell(),                 "Screencapture Plug-in",                 "Screenshot created");     }       /**      * Selection in the workbench has been changed. We      * can change the state of the 'real' action here      * if we want, but this can only happen after      * the delegate has been created.      * @see IWorkbenchWindowActionDelegate#selectionChanged      */     public void selectionChanged(IAction action, ISelection selection) {     }       /**      * We can use this method to dispose of any system      * resources we previously allocated.      * @see IWorkbenchWindowActionDelegate#dispose      */     public void dispose() {     }       /**      * We will cache window object in order to      * be able to provide parent shell for the message dialog.      * @see IWorkbenchWindowActionDelegate#init      */     public void init(IWorkbenchWindow window) {         this.window = window;     } }

Gruss Tom

Auch wenn es nach fünf Jahren ein wenig spät kommt. Muß es in der run-Methode nicht

gc.copyArea(image, rectangle.x, rectangle.y);

heißen um die aktive Anwendung zu bekommen?

Trotzdem ein tolles Beispiel.
