Label not Visible [message #77097]

Hey all,

I don`t know if it`s a bug or a 'feature'?!
I created my own Entrypoint, but in the first Version:

final Display display = new Display();
final Shell shell = new Shell(display);
shell.setSize(560, 420);
shell.setText("Shell Title");

shell.setLayout( new FillLayout());

final Label label = new Label(shell, SWT.CENTER);
label.setText("============= Start =================");
label.setVisible(true);
label.setEnabled(true);

shell.open();
...
the Label is not visible.
If I move the shell.setSize(560, 420) between the label.setEnabled(true)
and shell.open() the Label shows just fine.

Hope I don`t out me as an Newbie.

Regards
Michael

Hi Michael,

Either you call shell.setSize() just before shell.open() or use
shell.pack() to trigger layouting. Otherwise the shell isn't layouted
and thats why your label isn't visible.

Regards,
Stefan.
