How can I know wether a pushbutton is toggled or not?

Question

Like seen on the picture, I have 96 pushbuttons initially green. Once clicked on a button ( toggled(bool) ) it becomes red.

What I want to do is to disable all red buttons once I click on the OK button.

How can I do that ?

If the OK button closes this window, what should I do so that the modifications ( disabled buttons ) are saved once I open the window again!

Have you considered using `isCheckable` and `isChecked`? – zeFrenchy Jan 22 '20 at 10:26 — zeFrenchy, Jan 22 '20 at 10:26

in qt togglebuttons are jut norlmal buttons, those inherit the qAbstractbutton

there you can use the bool isChecked() method:

This property holds whether the button is checked.

Only checkable buttons can be checked. By default, the button is unchecked.

so I imagine, you have the grid in some kind of array you can browser in a for loop...

so you can do:

for(...)
{
    ui->x->setEnabled(!ui->x->isChecked());    
}

The suggestion still applies, I'd consider to link Qt 5 docs though, nowadays. — Frank Osterfeld, Jan 22 '20 at 11:07
