Re: [Matplotlib-users] Is matplotlib compatible whith PyQt4 ?

[Samuel G. <sg...@ol...>]

Thank you,
Sorry I did known the existence of matplotlib.backends.backend_qt4agg.
It is more easy than I thought.

but I still have a problem. This is my code :

import sys

from PyQt4.QtCore import *
from PyQt4.QtGui import *

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

#------------------------------------------------------------------------------
class MyWidget(QWidget):
    def __init__(self, parent=None):
        QWidget.__init__(self, parent)
        self.menuBar = QMenuBar()
        self.fileMenu = QMenu(self.tr("&File"), self)
        self.menuBar.addMenu(self.fileMenu)

        mainLayout = QVBoxLayout()
        mainLayout.setMenuBar(self.menuBar)
       
        self.setLayout(mainLayout)

#------------------------------------------------------------------------------
if __name__ == "__main__":
    app = QApplication(sys.argv)
    dialog = MyWidget()
    dialog.show()
    sys.exit(app.exec_())

and it does not works because the main window is blocking.
But when I comment this line :
#from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as
FigureCanvas
it works !
What  am I doing wrong ?

PyQT4 is 4.0.1
Matplotlib is 0.87.4
