Hello everyone,
regarding the last tests I modified the code. Now:
""""""
def main(): # outside the Extension class
app = QApplication(sys.argv) # A new instance of QApplication
form = ExampleApp() # We set the form to be our ExampleApp (design)
form.show() # Show the form
app.exec_() # and execute the app
def performAction(self, action, glwidget): # inside the Extension class
self.emit(SIGNAL("message(const QString&)"), "performing action...")
# return the undo command (ownership will be handled automatically)
# return the undo command (ownership will be handled automatically)
main()
""""""
Now avogadro finishes when I push the button, as the last sections of the
first e-mail, I am not sure about the reason (Crash the program or the
probably not intentional call of the quit() function)
I tried to attach the current version of the example script.
Thank you again.
R.R.
