C++ Event (Focus) Handling

Answer 1

Okay, first off, here is the code to put in your BasicPanel class:

void OnKillFocus(wxFocusEvent& event);

Then add the following to the end of your BasicPanel constructor:

Connect(ID_TEXTCTRL,
        wxEVT_KILL_FOCUS ,
        (wxObjectEventFunction)&BasicPanel::OnKillFocus);

You will need to repeat the above code for each text control and replace ID_TEXTCTRL with the actual ID of the controls.

Then the code below will get called whenever one of the controls loses focus.

void BasicPanel::OnKillFocus(wxFocusEvent& event)
{
    // code goes here...
}

To determine the ID of the control that generated the event within OnKillFocus, you can use the following:

event.GetId()
