wxpython: "background text" into MDI parent frame

[dazzler]

How do I add "background text" into MDI parent frame, the text will be now erased if I move the MDI Parent frame, or I can also erase text with moving MDI Child frame, need to somehow refresh the text, how to do it?

wx.FULL_REPAINT _ON_RESIZE style on MDI parent frame would help a little, but I would also need to call self.Layout() (and I still can erase the text moving child frame over the text...)

background_text = wx.StaticText(s elf, id=-1, label="This is background text", style=wx.ALIGN_ RIGHT)
background_text .SetBackgroundC olour("#BB0000" )

vbox = wx.BoxSizer(wx. VERTICAL)
vbox.AddSpacer( (1,1),1)
vbox.Add(backgr ound_text, 0, wx.ALL|wx.ALIGN _RIGHT, 5)

self.SetAutoLay out(True)
self.SetSizer(v box)
self.Layout()

child_frame = wx.MDIChildFram e(self, -1, "MDI child", size=(150,150))
child_frame.Sho w(True)

app = wx.PySimpleApp( )
MyFrame().Show( )
app.MainLoop()
