I have designed my current GUI with QT Designer. The underlying code creates and starts multiple threads. For each thread I have a set up several QPushButtons: Start, Stop, Pause, Resume, and Status. I'd like to group them, but they are not exclusive, so I need to set the enabled attribute from the signaled slot, for each related button, depending on which button has been clicked. I've tried creating a QButtonGroup for each set of buttons. I can get the sender(), but don't see how to get access to the other buttons which belong to the group. Have tried several things, but having no luck.

OK, I think I have what I need on this. The problem was how to I set the enabled states of buttons in a group based on the identity of the sender?

I have a possible x number of threads that can be controlled. The objectNames of the buttons in each QButtonGroup are as follows:

pushButton_start_x
pushButton_stop_x
pushButton_status_x
pushButton_pause_x
pushButton_resume_x

In my Python code I have the following dictionary:

# Each key represents a button type that requires setting the group's
# buttons enabled state

# Each key's values map to these buttons: [start,stop,status,pause,resume]

testManagerButtonEnableStates = {}
testManagerButtonEnableStates["start"] = [False,True,True,True,False]
testManagerButtonEnableStates["stop"] = [True,False,True,False,False]
testManagerButtonEnableStates["pause"] = [False,False,True,False,True]
testManagerButtonEnableStates["resume"] = [False,True,True,True,False]

This routine sets the states based on the objectName of the sender:

# Note that the status button does not require any action here

def setButtonGroupEnabledStates(self):
    buttonType = str(self.sender().objectName().toAscii()).split('_')[1]
    if buttonType == "status":
        return
    i = 0
    for button in self.sender().group().buttons():
        button.setEnabled(self.testManagerButtonEnableStates[buttonType][i])
        i+=1

Maybe not the most efficient, but it gets me there...
