Is in wxPython event like
root.bind('<Double - 1>,function)
i need on one wxButton 2 event, normal and double. How to create this?

Take a look at the wxButton demo at:

You might have to modify the events slightly.
wx.EVT_BUTTON is basically a single left mouse click.
wx.EVT_LEFT_DCLICK is your left double click.
