Hi Nils. I have never tried to do a real printout, so I am no expert here. My use case was almost always to directly create pdf or ps documents, which can be done nicely using the several print_* methods of the figurecanvas.
You can use Actions for your case instead of a widget. Actually they should considered to be recommended when using Qt4. Actions are a very elegant way to attach functionality to a program. So define an action like you suggested, and add it to the toolbar using the addAction method of the toolbar. Then you might want to implement a slot, that you in turn connect to the "triggered" signal of your action, which implements the real printing. I can't really help you with the printing itself, but have found an implemented strategy after a bit googling. That might be a start ... http://gotm.git.sourceforge.net/git/gitweb.cgi?p=gotm/gotm;a=blob;f=gui.py/xmlplot/gui_qt4.py;h=6e0239a958580ac2a35cd26653d83f26909fda24;hb=163207fa3fcc86f91008056c77e9c31fd6a9e246 Have a look at the onPrint method here. Hoping again that this was helpful.

Hence I have tried import sys import numpy as np from PyQt4.QtCore import * from PyQt4.QtGui import * from matplotlib.figure import Figure from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as FigureCanvas from matplotlib.backends.backend_qt4agg import NavigationToolbar2QT as NavigationToolbar2 class ViewWidget(QMainWindow): def __init__(self): QMainWindow.__init__(self) # create a simple main widget to keep the figure self.mainWidget = QWidget() self.setCentralWidget(self.mainWidget) layout = QVBoxLayout() self.mainWidget.setLayout(layout) # create a figure self.figure_canvas = FigureCanvas(Figure()) layout.addWidget(self.figure_canvas, 10) # and the axes for the figure self.axes = self.figure_canvas.figure.add_subplot(111) x = np.linspace(0.,2*np.pi,100) self.axes.plot(x,np.sin(x)) # add a navigation toolbar self.navigation_toolbar = NavigationToolbar2(self.figure_canvas, self) layout.addWidget(self.navigation_toolbar, 0) # create a simple widget to extend the navigation toolbar # anotherWidget=QLineEdit() printer = QPrinter() anotherWidget= QPrintDialog(printer,self) # add the new widget to the existing navigation toolbar self.navigation_toolbar.addWidget(anotherWidget) if __name__=="__main__": app=QApplication(sys.argv) mw=ViewWidget() mw.show() sys.exit(app.exec_()) How do I connect the plot with the printer ? How can I replace the printer dialog by a small icon ? I found the lines a = self.addAction(self._icon('filesave.svg'), 'Save', self.save_figure) in backend_qt4.py Nils ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
