Same here with your sample:

Central widget should have width=1000, height=700
but central widget has width=960, height=600

I resorted to WXAgg for the time being. Waiting for some updates till I hear
a resolution. The annoying part is when I created a plot using specified
width and height Qt4Agg doesn't follow these dimensions as in this case and
resulting savefig(file.pdf) produces wrongly sized file unless I manually
extend the figure area and re-issue a savefig afterwards.
