Autoexclusive property for QPushButtons

Qtstarter121

So I have a bunch of QPushButtons in QGridLayout and they all have autoExclusive = true. These buttons are loaded from a .ui file.
I added two new QPushButtons to the layout programmatically, and set the same property autoExclusive = true for them.

In my code when each button is clicked I have the following

  if (!button->isChecked())
   {
      button->setChecked(true);
   }

Now when I click on either of these two new QPushButtons, they don't get unchecked when I click any other button, but the rest of them do, so I'm not sure why the autoexclusive property doesn't work for these buttons that were added programmatically.

I haven't been able to find a cleaner solution with respect to the auto exclusive property, but the following works for me in the meantime:

   QGridLayout* gL = QWidget::findChild<QGridLayout *>("buttonsLayout"); 
   QPushButton* btn = 0;
   for(int i = 0; i < gL->count(); ++i)
   {
     if(btn = dynamic_cast<QPushButton*>(gL->itemAt(i)->widget())) 
     {
        if(btn != button) // where button is the button that was just recently clicked.
        {
           btn->setChecked(false);
        }

     }
   }

Hi,

Are you looking for QButtonGroup::setExclusive ?

Qtstarter121

@SGaist No because my buttons are not part of a QButtonGroup. They are simply arranged in a QGridLayout.

Hi.
autoExclusive only works if they have same parent.
So check what the working buttons parent is -
and set the same for the new dynamically allocated buttons.
If the first buttons are inserted with Designer,
you can go and see what is set as parent (in setupUI() )
and use the same.

@mrjj Yes the other buttons were created with Qt Designer in a .ui file. I actually looked at the code for the UI and I ensured that my programmatically created buttons had the same parent, but no change. That is why I'm confused as to why this is happening.

That is very odd as i did that as a small test.
Stole the code from setupUI and added via button.clicked() and
it the worked as the Designer inserted ones.
I just used a widget with a layout.

Have you tried a small test ? ( to rule out something else in actual project)
