wxTreeEvent, Connect

[Torsten Mohr]

Hi,

in a class derived from wxDialog i use a wxSplitterWindow and in
that one i use a wxTreeCtrl.

I'd like to get the events for a selection-change in my dialog class
and i try to use Connect for that:

In the constructor of the wxDialog:


  split = new wxSplitterWindow(this, CHR_SETTINGS_SPLIT,
    wxDefaultPosition, wxDefaultSize);

  stree = new wxTreeCtrl(split, CHR_SETTINGS_TREE,
    wxDefaultPosition, wxDefaultSize,
    wxTR_HAS_BUTTONS | wxTR_HIDE_ROOT | wxTR_SINGLE );

  Connect(wxEVT_COMMAND_TREE_SEL_CHANGED,
    wxTreeEventHandler(ChrXmlSettings::OnSelChanged));



void ChrXmlSettings::OnSelChanged(wxTreeEvent& e)
{
}

When linking i get unresolved symbols for:

ChrXmlSettings::GetEventHashTable
ChrXmlSettings::GetEventTable

Those are virtual methods of the wxEvtHandler and wxDialog is
derived from it.

Should i implement those methods?  What should be in there?

Is there a way around that?

Is there a better way to get notified of a selection change of
the wxTreeCtrl?  I don't really want to create a new class.

Of course i know the example in the documentation and the Wiki,
but they don't help here.  Also the book did not really help.


Thanks for any hints,
Torsten.
