I created a label that contains a string. The string represents a map. I
have a "Next" button and everytime I press it the objects on the map
should move. So when I press "Next" I change my string ( str =
modify_string(str) ) and and then call label.setText(str) to update my
label. However, the screen flashes everytime I update my label. Is there a
way I can avoid the flashing? Maybe I should not use a label for what I
want to accomplish?

label.setText(strings[index++ % 2]);
label.addListener(SWT.MouseDown, new Listener() {
public void handleEvent(Event event) {
label.setText(strings[index++ % 2]);
}
});
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();
}
display.dispose();
}
