[Matplotlib-users] Matplotlib+Qt. Problem with plot resizing

[Alexander B. <vo...@ua...>]

Hi, list!

I have a problem with embedding matplotlib in Qt based GUI. I read manual and look at
example "embedding_in_qt4.py". I create GUI with QtDesigner. For matplotlib plot I create
a QWidget. Then in runtime I embed a matplotlib plot im my GUI, into this QWidget. Here some code:

from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.figure import Figure

class dlgStatist( QDialog, Ui_dlgStatistics ):
	def __init__( self, iface ):
		QDialog.__init__( self )
		self.iface = iface
		self.setupUi( self )
		
		# prepare figure
		self.figure = Figure()
		#self.figure.set_figsize_inches( ( 4.3, 4.2 ) )
		self.axes = self.figure.add_subplot( 111 )
		self.figure.suptitle( "Frequency distribution", fontsize = 12 )
		self.axes.grid( True )
		self.canvas = FigureCanvas( self.figure )
		self.canvas.setParent( self.widgetPlot )
                .......

All looks fine, but when user change window size, matplotlib plot doesn't resized. I try to set
SizePolicy to matplotlib figure (as explained in example) but this don't help.
Where is my mistake and can anyone give me a little example how to embed matplotlib plot
in GUI created with QtDesigner? I really need resizible plot into Qt dialog.


Sorry for my bad English, I'm Ukrainian.
