[matplotlib-devel] Bugs in Qt4 backend with the latest PyQt release

[Pierre R. <co...@py...>]

Hi all,

I'm posting to report two bugs in 'backend_qt4.py' with the latest PyQt 
release:
(see eventually the attached test script)

(1) in class 'NavigationToolbar2QT' l. 285-300 : I had to replace '.svg' 
by '.png' for all the icons to be displayed correctly on the navigation 
toolbar (only one was already loaded in the right file format).

(2) I still experience slow performance of pan/zoom feature with the 
latest PyQt release (the last release for which I had no problem is the 
4.3.3 release). You'll find attached a simple test script: with PyQt 
4.3.3 pan/zoom is real-time, and with PyQt 4.4.3 it's really slower (in 
fact, zooming and panning are happening at the right speed but after a 
short delay from the mouse click)

Regards,
Pierre Raybaut
