Sorry if this is a dumb question, but I'm relatively new to working with
GTK.
Is it actually possible to create a graphics on the display and draw to it?
That is, can I draw directly to the desktop?
I tried writing the following very simple app, but nothing appears on the
screen. Am I missing something?
Note that the same app works fine on WinXP.
Stef
import org.eclipse.swt.SWT;
import org.eclipse.swt.graphics.GC;
import org.eclipse.swt.widgets.Display;
public class TestDisplayGraphics {
public static void main(String[] args) {
Display d = new Display();
GC gc = new GC(d);
gc.setBackground(d.getSystemColor(SWT.COLOR_GREEN));
gc.fillRectangle(100,100,200,200);
gc.setBackground(d.getSystemColor(SWT.COLOR_RED));
gc.fillRectangle(400,400,200,200);
gc.dispose();
System.out.println("Test complete");
}
}
