wxTextCtrl work:

Browse Source 
1. horz scrolling (not perfect yet)
2. more actions (clipboard, double click)
3. wxCaret fixes
4. clipboard support
5. wxTE_PASSWORD support

wxScrolledWindow/wxlistBox:

better hit test calculation: take into account GetClientAreaOrigin()

fix for wxGTK bug in wxDC::Blit() in wxWindow::ScrollWindow

draw transparent radio bitmaps under GTK

wxWindow::ScrollWindow() can now scroll a part of window only
