How to close wx.DirDialog programmatically?

Question

I have wxpython app that open wx.DirDialog on button click.

dlg = wx.DirDialog(self, \"Choose a directory:\", style=wx.DD_DEFAULT_STYLE)
    if dlg.ShowModal()          


        

Answer 1

It is my testing code.

I can test Destroy(), Close() and EndModal() on Modal and Non-Modal wx.DirDialog()

To close modal dialog I had to use Timer - because modal dialog is blocking access to the main window.

It can't close dialog only if I do

self.dlg = None
self.dlg.EndModal(wx.CANCEL) # or Destroy() or Close(True)

And one more thing - I use Linux Mint 15, Python 2.7.4, wxPython 2.8.12.1 :)
