[wx-dev] wxApp::OnExceptionInMainLoop() and modal dialogs.

[Christopher Davis]

Hello,

When wxApp::OnExceptionInMainLoop() handles an uncaught exception 
from an event handler while a modal dialog is open, is it (or should 
it be) possible to shut down only the dialog's event loop and not the 
application's primary mainloop by returning false from 
wxApp::OnExceptionInMainLoop()?

I've run into an issue experimenting with wxGTK, and it's perhaps
different for other platforms, but when returning false from 
wxApp::OnExceptionInMainLoop() while a modal dialog is open causes
both the dialog's event loop and the mainloop to be terminated.
The issue is that wxDialog::EndModal() doesn't check to see if the
main loop was terminated externally, calling gtk_main_quit() in every
case. So, gtk_main_quit() is called twice, once due to the unhandled
exception, and again in wxDialog::EndModal() when the dialog is 
destroyed.

Is this the intended behavior or a bug?

Thanks,
