Updating labels during runtime [message #465154] Wed, 07 December 2005 04:53 Go to next message

I'm trying to change the image for a Label during runtime based on
input, and it doesn't change the image, but instead keeps the existing
image. Is there anything I could be forgetting to do to get this working?

Thanks, Mike

The following works for me:

public static void main (String [] args) {
Display display = new Display ();
final Image[] images = new Image[] {
display.getSystemImage(SWT.ICON_ERROR),
display.getSystemImage(SWT.ICON_INFORMATION),
display.getSystemImage(SWT.ICON_QUESTION),
display.getSystemImage(SWT.ICON_WARNING),
};
Shell shell = new Shell (display);
shell.setLayout(new FillLayout());
final Label l = new Label(shell, SWT.BORDER);
l.setText("Click button to change image");
Button b = new Button(shell, SWT.PUSH);
b.setText("change image");
b.addListener(SWT.Selection, new Listener() {
int index = 0;
public void handleEvent(Event e) {
l.setImage(images[index]);
index = (index + 1) % images.length;
}
});
shell.setSize(300, 300);
shell.open ();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}
