fugir ao repetir

I got stumped when trying to catch the file selected with the generic directory tree: there are no events in that control! After some googling I understood: the "selection" event is fired by the tree control, not by the window / control that contains it; if ID_DIR_CTRL is the generic control ID this does not work:

BEGIN_EVENT_TABLE(MyFrame,wxFrame)
    EVT_TREE_SEL_CHANGED(ID_DIR_CTRL, MyFrame::OnTreeSelChanged)
END_EVENT_TABLE()

One solid solution was pointed by Joseph Blough using a dynamic connection, that is an (more object like) alternative to event tables. I'll check that on a sunnyless Sunday, for now I stick with the old event table setting the wxTreeCtrl ID:

dirCtrl->GetTreeCtrl()->SetId(ID_TREE_CTRL);

Documentation says that the identifier should not be modified but, hey, I'm setting it in the constructor. And it works!

No, it does not work. Events are catched, but are also lost by the generic directory tree. Sunnyles Sunday on Tuesday, that is. I could get all tree events with wxID_ANY but I'm seeing some more trees coming...
