Re: [matplotlib-devel] problem with 0.72/CVS qtagg on linux

[Ted D. <ted...@jp...>]

John,
Looks like that ctor was added in 3.2 of qt.  Looking back through 3.0, I 
think you should be able to just change the line to look like this:

a = qt.QAction( text, qt.QIconSet( image ), text,
                 qt.QKeySequence('M'), self.window )

which is a ctor supported by even version 2.3 of qt.

We tend to keep up w/ the latest versions of Qt pretty regularly.  I may 
have to keep an old Qt/PyQt build around to test this stuff against...
