This waits until idle time (when all messages have been processed) to actually delete the window, to avoid problems associated with the GUI sending events to deleted windows. -Don't create a window on the stack, because this will interfere with delayed -deletion. +In general wxWindow-derived objects should always be allocated on the heap +as wxWidgets will destroy them itself. The only, but important, exception to +this rule are the modal dialogs, i.e. wxDialog objects which are shown using +wxDialog::ShowModal() method. They may be allocated on the stack and, indeed, +usually are local variables to ensure that they are destroyed on scope exit as +wxWidgets does not destroy them unlike with all the other windows. So while it +is still possible to allocate modal dialogs on the heap, you should still +destroy or delete them explicitly in this case instead of relying on wxWidgets +doing it. If you decide to allocate a C++ array of objects (such as wxBitmap) that may be cleaned up by wxWidgets, make sure you delete the array explicitly before
