Qpushbutton is used to send the checkable attribute of toggled (bool)

 

The checkable option is not selected by default. The button is a trigger button by default. Press it and it will pop up immediately.

After the checkable option is selected, the button changes to the toggle button, which can be in two states: Press/play; at this time, the button can emit a toggled (bool) signal, combined with the slot function setvisible (bool), it can be used to display controls alternately;

 

The two "more" buttons in the figure below are in the pop-up status and the press status below.

 

Problem:

I have the follwing code whereMorebuttonIsQpushbutton. When I toggle the button, nothing happens.

Shouldn't it show or hideSecondarygroupboxAndTertiarygroupbox?

 Qobject  ::  Connect  (  Morebutton  ,  Signal (  Toggled  (  Bool  )),  Secondarygroupbox  ,  Slot  (  Setvisible  (  Bool  )));    Qobject  ::  Connect  (  Morebutton  ,  Signal  ( Toggled  (  Bool  )),  Tertiarygroupbox  ,  Slot  (  Setvisible  (  Bool  ))); 

Answer:

Most likely, your Pushbutton is notCheckable (). Try

 
Morebutton->Setcheckable(True)
 

A non-checkable button never emitsToggled (bool)Signal.
