Qthread Updating Ui Statusbar?

I have a simple pyqt gui which creates a qthread to open a file and read some information. I want to update the statusbar of my gui. Normally, this would be my function call to u

Solution 1:

You must never attempt to update the GUI from outside the GUI thread. Instead, add a custom signal to the worker thread and connect it to a slot in the GUI:

class WorkThread(QtCore.QThread):
    statusMessage = QtCore.pyqtSignal(object)       
    ...

    def run(self):
        self.statusMessage.emit(self.text)

class gui1(QtGui.QMainWindow):    
    def __init__(self, parent=None):    
        super(gui1, self).__init__(parent)
        self.mythread = WorkThread(text)
        ...
        self.mythread.statusMessage.connect(self.handleStatusMessage)

   @QtCore.pyqtSlot(object)
   def handleStatusMessage(self, message):
       self.ui.statusBar().showMessage(message)
