Example 5 with ImageTransfer

use of org.eclipse.swt.dnd.ImageTransfer in project dbeaver by serge-rider.

the class BaseChartComposite method doCopyToClipboard.

protected void doCopyToClipboard() {
    Image image = new Image(Display.getDefault(), this.getBounds());
    GC gc = new GC(image);
    try {
        this.print(gc);
    } finally {
        gc.dispose();
    }
    ImageTransfer imageTransfer = ImageTransfer.getInstance();
    Clipboard clipboard = new Clipboard(Display.getCurrent());
    clipboard.setContents(new Object[] { image.getImageData() }, new Transfer[] { imageTransfer });
}
