[wxPython] paint to a modal dialog

wxPython Users

Hello all,

is there any way to paint to a modal dialog? I am trying to add
a 'New...' button to the standard wxDirDialog by blitting an
image of the button in the right place and then catching the
mouse move events - but I don't seem to be able to paint to
the dialog; OnPaint in the code below is not even called
in the [unfinished] code below (and neither is
OnLeftUp):

class ExtDirDialog(wxDirDialog):
    def __init__(self, parent, **optionD):
        apply(wxDirDialog.__init__, (self, parent), optionD)
        EVT_PAINT(self, self.OnPaint)
        EVT_LEFT_UP(self, self.OnLeftUp)

···

#
    def OnLeftUp(self, ev):
        x = ev.GetX()
        y = ev.GetY()
        leftX,leftY,rightX,rightY = self._cornerT
        if leftX <= x <= rightX and leftY <= y <= rightY:
            return self.OnNew()
        #
        ev.Skip()
    #
    def OnPaint(self, ev):
        dc = wxPaintDC(self)
        bmp = wxBitmap('c:\\newbutton.bmp',
                       wxBITMAP_TYPE_BMP)
        memdc = wxMemoryDC()
        memdc.SelectObject(bmp)
        width = bmp.GetWidth()
        height = bmp.GetHeight()
        cornerT = self._cornerT = (100,100,100 + width, 100 + height)
        apply(dc.Blit, cornerT + (memdc, 0, 0, wxCOPY))
        #
        ev.Skip()
    #
    def OnNew(self):
        pass

Any ideas?

Thanks,

Oliver

If you are on MSW then wxDirDialog is not a real wxDialog but just a wrapper
around the MSW common dialog. As such, it is not possible to catch events
for it. This is an unfortunate side effect of using the common dialogs from
MS.
