Version: 1.3.0
Fix Version: 1.3.0 (r8530)
Please apply r. 8530. It solves the issue raised by your
first test program.
The focus was indeed not correctly done after a window was created
because some code present in the Carbon version was not reflected
in the Cocoa version. This code has now been added.
As for the second test program: the
win->take_focus();
statement does not change the focus to the large window because
there's no focus-accepting widget in this window. Therefore
the focus remains to the small window that gets closed by cmd-W.
I believe its's not a bug that an empty window can't be given
the focus by the take_focus() function.
If you replace win->take_focus() by
Fl::focus(win);
the expected behavior is observed, because the focus does get
set to the large window.
If you add a focus-accepting widget in the large window, as in the
attached focus3.cxx, the expected behavior is observed, both
with and without the r.8530 Cocoa fix.
Please, post your observations so I know whether to close this STR.
Hi Manolo - r8530 indeed fixes the first issue: awesome!
I still observe the second issue either with win->take_focus() or with
Fl::focus(win). (In my code my window event handler accepts the FL_FOCUS
and FL_UNFOCUS events.)
Attached is a new small example using either win->take_ficus() or
Fl::focus(win). Both do not seem to work as expected.
