Using this your OnRun will become somthing like:
def OnRun( self, evt ):
def after():
installation_task()
self.run_button.SetLabel('Install')
self.run_button.SetLabel('Installing..')
wx.Callafter( after )
However if installation_task takes a long time you will need to use
threads, something like (untested):
def OnRun( self, evt ):
def after():
self.run_button.SetLabel('Install')
def task():
installation_task()
wx.Callafter( after )
self.run_button.SetLabel('Installing..')
import threading
threading.Thread( target = task ).start()
