How can I unmaximize programmatically a maximized frame in wxPython?

Question

Let's say I have a simple application such as the following:

import wx

app = wx.App()

frame = wx.Frame(None, -1, 'This is the frame title')
frame.Show()
frame.Maximize()    

app.MainLoop()

Is there a method I can call on the frame to un-maximize it? I have tried frame.Unmaximize() and frame.Maximize(False) but the former is undefined, while the latter seems to 'fail' silently in Ubuntu.

Here it says that Maximize(False) is the way to go. Is there a bug I should submit, or is there something else I miss here?

Answer 1

Just tried this program under OSX, Win7 and Ubuntu:

import wx

app = wx.App()

frame = wx.Frame(None, -1, 'This is the frame title')
frame.Show()
frame.Maximize() 
frame.Maximize(False)   

app.MainLoop()

On OSX and Win7 the frame visibly maximises then minimises.

On Ubuntu (wxpython 2.8.11 gtk-unicode), the Maximise commands appear completely ignored. I can delete the Maximize(False) line and the frame still isn't maximised.

This is with xfwm4 on Ubuntu 11.10

Looks like a bug to me. But it may also be a window manager quirk.

Amusingly, google finds a bug report where Frame.Maximize() works only on windows. But it is 11 years old. Maybe Linux has not been added yet :)

You could also try Restore(). While under MSW and OS X it's exactly the same as Maximize(false), in wxGTK it's implemented slightly differently, so perhaps it works even under Ubuntu.
