Hi,
in the following snippet I use 2 composites (A+B) which overlay each other.
A has a text field and a label. B is just an empty composite for event
receiving. If you click on the composites, the drawing order is reversed (so
one time A is above B and the other time B above A). Both composites do not
use a background.
While the snippet works as expected on Firefox (3.5) (namely, you cannot
edit the text field while B is above A), is does not on IE (8), where you
can always edit the text field.
Which behaviour is correct? Or what can I do so that this works on all
browsers?
---
final Composite h = new Composite(parent, SWT.NONE);
h.setBackgroundMode(SWT.INHERIT_DEFAULT);
final Composite a = new Composite(h, SWT.NONE);
a.setLayout(new GridLayout(1,false));
final Composite b = new Composite(h, SWT.NONE);
b.setLayout(new GridLayout(1,false));
a.setBackground(null);
a.setBackgroundImage(null);
b.setBackground(null);
b.setBackgroundImage(null);
final Label l = new Label(a, SWT.NONE);
l.setText("Composite A is active");
Text t = new Text(a, SWT.NONE);
t.setText("I'm on composite A. Try to edit me.");
a.moveAbove(b);
h.addControlListener(new ControlAdapter() {
public void controlResized(ControlEvent e) {
a.setBounds(h.getBounds());
b.setBounds(h.getBounds());
}});
a.addMouseListener(new MouseAdapter() {
public void mouseUp(MouseEvent e) {
System.out.println("a clicked");
a.moveBelow(b);
l.setText("Composite B is active");
}});
b.addMouseListener(new MouseAdapter() {
public void mouseUp(MouseEvent e) {
System.out.println("b clicked");
a.moveAbove(b);
l.setText("Composite A is active");
}});
Regards,
Niels

to find out which behavior is correct, run the snippet in SWT. Apart
from that it looks like a bug. Could you file a bugzilla?
Cheers,

in SWT B allways "overdraws" A. At least you cannot edit the text field, if
A is below B...
Neverthless, Bug 299629
Thanks,
