Hi, Following up on my own post here...

This I can do now using the advice from Pat (in previous posting which I can't link to right now since it isn't archived, but the subject was "Getting user input while in python shell plugin"). I just import PyQt4.QtGui and go from there. > Secondly how can one gracefully end a python shell plugin? A > sys.exit() just kills paraview since the plugin is running in the > same process I guess. Throwing an exception is OK if the user has the > python shell open, otherwise it is just a silent failure. So the failure won't be silent now, since I can popup a warning or error box, then I can just raise an exception to stop execution. For completeness here we go: import PyQt4.QtGui # this is a dummy widget to use as the parent for other widgets that need a parent wid = PyQt4.QtGui.QWidget() # get some user input ret = PyQt4.QtGui.QInputDialog.getText(wid, 'hi', 'first question') # do some other stuff # oh dear a warning ret = PyQt4.QtGui.QMessageBox.warning(wid, 'hi', 'there was a recoverable problem', PyQt4.QtGui.QMessageBox.Abort, PyQt4.QtGui.QMessageBox.Retry, PyQt4.QtGui.QMessageBox.NoButton) if ret == PyQt4.QtGui.QMessageBox.Abort: raise ValueError, "pooed out" else: ret = PyQt4.QtGui.QInputDialog.getText(wid, 'hi', 'second question') Matt _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview
