how to add "are you sure?"

Post by Jacek Poplawski » Tue Feb 07, 2012 9:16 pm

Is there a predefined way to add "are you sure?" dialog before quitting?
I can't find it anywhere.

if you looked at the documentation for wxMessageBox that asadilan suggested you would have seen that you could do something like this

Code: Select all

    int answer = wxMessageBox("Quit program?", "Confirm",
                              wxYES_NO | wxCANCEL, main_frame);
    
    if (answer == wxYES)
        main_frame->Close();
It is a convenience function that shows a wxMessageDialog with yes and no buttons and returns a value based on what the user selects. You can't get much easier than that.

Sure, but where "are you sure" should be called from.
The event you need to catch is wxEVT_CLOSE_WINDOW. There was a thread a few days ago, which solved the same problem:

The event can be (not always!) vetoed. Thus, "if you aren't sure" then check CanVeto() and if you can Veto() then Veto(). The event is sent from Close(), do not call Close() from the handler. Call Destroy().
