Hello,
I've been looking into a bug which crashes Gobe Productive whenever you
click twice on one of its toolbar popup-menu buttons (i.e. click on the
button again while the popup-menu is already open -> crash).
The problem is in BMenu -- when you call BMenu::Show() twice, it crashes
(view gets added twice which calls into debugger()). The second click
on a popup menu in Gobe running on Haiku causes Show() to be called a
second time.
I checked how it works in BeOS. With a little test application I
verified that it also crashes when BMenu::Show() is called twice, so
Haiku is not different in this regard. However, when a BMenu is shown
on BeOS, you cannot click on anything else in the window until the menu
is closed again. That is why clicking twice doesn't crash when running
Gobe on BeOS: the second click doesn't register.
On Haiku, when a menu is open, you can still directly click other UI
elements (click goes through).
So, questions...
- is this different behaviour intentional? (I assume yes, in the end
click-goes-through seems more useful.)
- if yes, should we fix it by allowing BMenu::Show() to be called more
than once, i.e. ignore further calls when the menu is already open?

So long, jua
