I write some GUI with qt designer. This script is generated with qt designer and I wrote class mythread:

s.send('GLST\r\n')
glst = s.recv(1024)
if glst:
s.send('GLSC\r\n')
glsc = s.recv(1024)
print glst,glsc
s.close()
time.sleep(0.1)
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName(_fromUtf8("MainWindow"))
MainWindow.resize(800, 600)
self.centralwidget = QtGui.QWidget(MainWindow)
self.centralwidget.setObjectName(_fromUtf8("centralwidget"))
self.label = QtGui.QLabel(self.centralwidget)
self.label.setGeometry(QtCore.QRect(40, 40, 221, 31))
self.label.setStyleSheet(_fromUtf8("background-color:rgb(48, 48, 48)"))

In class mythread I have function run which is make connection to server and then send two commands on them. This function receives some data(glst,glsc) and now I want to see dynamically this data (glst,glsc) with while loop in textlabel in GUI.
But I dont know how connect thread to gui-textlabel.
Thanks for any ideas. Johny

I tried to use the mutex. Why did it automatically stop without an error.
Running will stop automatically after a while
This is my code, which can be run directly. Please help me to see what the problem is
Is my method wrong? Is there a better way to achieve it? I don't want my interface to get stuck

When I click the Test-set-parent_None button the QGroupBox Widget gets detached from MainWindow; and it gets re-attached if I click the Test-set-parent_Main button.
What is puzzling me it's why my eventFilter it's not working. If I close the QGroupBox with the X closing button (top right corner), I get the :
main before !!!!!! : None
main after !!!!!! : <__main__.MyApp object at 0x7ff7f35be550>
source.parent() : <__main__.MyApp object at 0x7ff7f35be550>
print that tells me that my QGroupBox is again the child of my MainWindow - but it doesn't show up. What am I missing in my 'eventFilter' implementation?
Returning True in the event-filter isn't always sufficient to prevent propagation of the event. For close-events, you must also explicitly ignore the event:
class MyApp(QMainWindow, Ui_MainWindow):
...
def eventFilter(self, source, event):
if event.type() == QtCore.QEvent.Close and source is self.models:
self.set_parent_main(source)
event.ignore()
return True
return super().eventFilter(source, event)
I created a back button in new window and next button in main window. After I clicked the next button to show a new window, it was successfully hides the current main window but when I clicked back button on the new window, the application automatically closes itself. Any idea?

Do not modify the code generated by Qt Designer but create another class that inherits
from the appropriate widget and use the initial class to fill it.

This is my example of python script.
here is hudsup.py output :
animated huds_up display
and my ui looks like this and i want my hudsup to displayed as mentioned :
Gui
You should not use the generated code directly, instead, create a new widget class and inherit from it:
class MainWindow(Ui_MainWindow, QMainWindow):
def __init__(self):
Ui_MainWindow.__init__(self)
QMainWindow.__init__(self)
self.setupUi(self)
To integrate your second widget you can just add it to Heads_up like you are doing now but don't need to call exec_:
self.hud_sup = HudSup()
self.Heads_up.addWidget(self.hud_sup)
This error keeps coming up on all applications that I build. I'm new at pyqt.
