I'm developing a PyQt4 application.I have created a button: ... self.start_button=QtGui.QPushButton("start simulation", self) ... that is connected to a function: ... self.connect(self.start_button, QtCore.SIGNAL('clicked()'), self.simulate) ... This is the function: ... def simulate(self): self.log_inspector.setText('') cmds=['rm engine','make engine', './ engine'] first_cmd="./parser "+str(self.filename) cmds.insert(0, first_cmd) for cmd in cmds: self.status_inspector.setText(cmd) status, output = commands.getstatusoutput(cmd) output_list=output.split("\n") output_list.reverse() output_def="\n".join(output_list) if status != 0: self.log_inspector.setText(cmd"... [ERROR]\n"+output_def) return self.status_inspector.setText("Done!") ... I would like to change the value of status_inspector (It's a QLabel) during the execution of the function. Is it possible?
If you want GUI-updates while performing time-consuming tasks, you need to make sure Qt's event-loop get's called every now and then. This should help you:
void QCoreApplication::processEvents ( QEventLoop::ProcessEventsFlags flags = QEventLoop::AllEvents ) [static]
