A) this is a good question for the wxPython list -- probably not a Mcac
issue

That being said:
self.run_button=wx.Button(self.panel,ID_RUN_BUTTON,label='Install')
self.Bind(wx.EVT_BUTTON, self.OnRun,id=ID_RUN_BUTTON)
I prefer this style:
self.run_button=wx.Button(self.panel, label='Install')
self.run_button.Bind(wx.EVT_BUTTON, self.OnRun)
explicit IDs are kind of ugly.

def OnRun(self,evt):
self.run_button.SetLabel('Installing..')
#call a function that does the installation task
installation_task()
#After task completion, set the button label back to "Install"
self.run_button.SetLabel('Install')
When I try doing this, it doesn't set the label to "Installing" while
the task is being performed. Any suggestions how do I achieve this?
wx blocks the event loop (and locks up the GUI) when handling an event,
so you need to separate out the installation_task() function. This may work:
def OnRun(self,evt):
self.run_button.SetLabel('Installing..')
#call a function that does the installation task
wx.CallAfter(installation_task())
#After task completion, set the button label back to "Install"
wx.CallAfter(self.run_button.SetLabel('Install'))
wx.CallAfter() puts an event on the event stack, then proceeds on, so
the OnRun() function can finish, the GUI will update, then the events
will be run.
Another option would be to post en event that's bound to the
installation_task() function, and call that from OnRun, then have it
post antoher even when it's done -- but that's really jsut a more
complicated way to do the above.
Third option: try calling "self.run_button.Update()", after changing the
button text.
