How to change JToolbars floating image

Question

Is there an easy way to change JToolbars floating image like the drag image in transferhandlers without having to code an own transferhandler?

Answer 1

Apparently paintDragWindow in the ToolbarUI does the thing.

I used this code which create an image of my toolbar as floating img.

@Override
protected void paintDragWindow(Graphics g) {
    BufferedImage img = getScreenShot(this.toolBar);
    g.drawImage(img, 0, 0, null);
    g.setColor(dragWindow.getBorderColor());

    g.drawRect(0, 0, toolBar.getWidth() - 1, toolBar.getHeight() - 1);
    System.out.println("paint drag window");
}

public static BufferedImage getScreenShot(Component component) {

    BufferedImage image = new BufferedImage(component.getWidth(),
            component.getHeight(), BufferedImage.TYPE_INT_RGB);
    // call the Component's paint method, using
    // the Graphics object of the image.
    component.paint(image.getGraphics()); // alternately use .printAll(..)
    return image;
}
