wxPanel::Enable on wxOSX/Cocoa

[Roman Hiestand]

Hello all

In my application, I have a wxPanel and several widgets as children,
grouped with wxBoxSizers (created with wxFormBuilder). During
a lengthy operation, I would like to Disable all widgets (except for
a progress gauge) and then re-enable them when the operation is finished.
On Windows and Linux/GTK, when I call

pPanel->Enable(false);

all widgets inside the wxPanel are disabled (or enabled when I call
Enable(true) ). On OS X/Cocoa, this does not happen. In fact, nothing
happens when I call Enable on a panel.
Is this a bug of wxWidgets on OS X/Cocoa?
Is there another way to disable/enable all widgets of a panel at once?

As a workaround, I now enable/disable all GUI elements individually.

Another thing: Disabling a wxNotebook also has no effect on OS X/Cocoa,
while it works perfectly on Windows and Linux/GTK.

I have tried several versions of wxWidgets, among them 3.0.0, 2.9.4 and
2.9.5. All have the same problem.

Thanks in advance
Roman

This is a known bug, see http://trac.wxwidgets.org/ticket/15495
