How do I make python script wait for pyqt button selection before continuing?-CodePudding

I'm trying to figure out how to insert a pyqt5 button into a python script and pause the script so it waits for the button press before it continues.

class MainWindow(QtWidgets.QMainWindow):

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
                
        self.ui.button.clicked.connect(pyfile.dothething)
        self.ui.button2.clicked.connect(pyfile.dotheotherthing)

def do_the_stuff():
    do some stuff
    wait for button press
    do_the_stuff()

the do_the_stuff() is going to ignore the button since normal python is not event based. How do I insert an event based wait function in the normal python script so it waits until the pyqt button is pressed?

CodePudding user response：

You could add state to your normal code to enable the flow control. For example:

class NormalCode:
    def __init__(self):
        self.state = 0

    def do_the_stuff(self):
        do some stuff
        while self.state == 0:
            # Prevent hammering the CPU
            time.sleep(0.1)
        do_the_stuff()

Then your button click can simply change the state:

def on_button_clicked(self):
    self.normal_code.state = 1

This should be fairly clean to implement as the normal code still doesn't need to know that the Qt layer exists.
