I’m trying to get a label on a button to be on two or more lines. I want to update this at runtime. I did like this:

self.btnGroupOne.SetLabel(u"test\ntest")

Yet, when I run the app, i just get a button with “testtest” on a single line as the label.

Am I forgetting a property that allows multiline labels or something?

BTW, when I do this:

self.btnNieuwTicket = wx.Button( self, wx.ID_ANY, u"Nieuw\nTicket", wx.DefaultPosition, wx.Size( 80,80 ), 0 )

the multiline does work…

It appears to be a confirmed bug in wxWidgets:

If you give the button a multi-line label at creation, SetLabel will then allow multiple lines.
