[matplotlib-devel] How to embed a matlibplot figure canvas into a pyqt4 GUI

2014-12-02 Thread Matthew Albert 
Hi,
I've used Qt Designer to construct a GUI.  An element of the GUI is a 
QGridLayout.  I've been trying to display a matplotlib plot in this 
QGridLayout.  I'm new at Python and have been trying to figure this out for the 
last week without success.  Essentially I'm trying to use elements of the 
example shown here:user_interfaces example code: embedding_in_qt4.py — 
Matplotlib 1.4.2 documentation

in my code shown here:http://paste.ofcode.org/JA2Hm8cP4jYD4c9NXgVGaE

Lines 23-25 is the problem area.  The error I get now is:RuntimeError: 
super-class __init__() of type MyStaticMplCanvas was never called

Conceptually what I think I'm doing is:# Line 24  Create an object of type 
MyStaticMplCanvas called thePlot.  This object is essentially a QWidget.thePlot 
= MyStaticMplCanvas(self.main_widget)
# Line 25  Pass thePlot as an argument to the addWidget method of the 
gridLayout I created in Qt Designer.self.ui.gridLayout.addWidget(thePlot)

Thx for the help.  I've spent about twenty hour trying to figure out this 
myself.  Any help you can give me would be great!
Matt

I think line 102 is your problem. self.axes doesn't exist yet.

P.S. - stuff like this will be covered in my upcoming book.
I am wrapping up with the embedding chapter tonight, even! Stay tuned for
announcements in the coming weeks.
