Ok, this has turned out to be wxWidgets peculiarity. Consider the following
event table:
BEGIN_EVENT_TABLE(MyFrame, wxFrame)
EVT_RADIOBOX(RadioPage_Radio, MyFrame::OnRadioBox)
EVT_RADIOBOX(wxID_ANY, MyFrame::OnCheckOrRadioBox)
END_EVENT_TABLE()
To convert this event table into a sequence of Connect() calls, you
have to invert the order, i.e.:
Connect(wxID_ANY, wxEVT_COMMAND_RADIOBOX_SELECTED,
wxCommandEventHandler(MyFrame::OnCheckOrRadioBox));
Connect(RadioPage_Radio, wxEVT_COMMAND_RADIOBOX_SELECTED,
wxCommandEventHandler(MyFrame::OnRadioBox));
This is because Connect() adds new events at the *beginning* of the
event handler list. I didn't know that and used the order of the
event table when converting it to a series of Connect() calls which
led to the general handler getting called first.
