[PyQt] Accessing a toggle button without clicking on it

[Phil]

Thank you for reading this.

How to I access my toggle button slot without clicking on the button?
For example:

if  hr == 19:
     # this button is accessible
     self. on_pushButton_clicked()

     # this fails because checked is not defined
     self.on_ledButton_toggled(checked)


Slots

     @pyqtSignature("")
     def on_pushButton_clicked(self):

     @pyqtSignature("bool")
     def on_ledButton_toggled(self, checked):
