How to select multiple checkboxes

[JacobNovitsky]

I have checkboxes stacked together
checkbox_1
...
checkbox_9
I want to be able to select some with something like this
click to checkbox_1
press shift
click to checkbox_9

all checkboxes selected

You have to implement such a logic by yourself.

you mean third party lib like libevdev?

I don't see why you would need this for such a simple task - but do what you want.

[JacobNovitsky]

For sure I would use any another more simple variant
what is your suggestion?

For what? Checking if a key is pressed?

[JacobNovitsky]

No, I need to select 10 check boxes with one click using SHIFT

It's FAR from perfect but should be something like this

private:
int lastPressedCBox = -1;
QList<QCheckBox*> checkBoxesContainer;

for(int i=0;i<checkBoxesContainer.size();++i)
QObject::connect(checkBoxesContainer.at(i), QCheckBox::clicked,[i,this](){
    if(lastPressedCBox>=0 && QGuiApplication::queryKeyboardModifiers() & Qt::ShiftModifier){
        for(j=std::min(i,lastPressedCBox);j<=std::max(i,lastPressedCBox);++j)
            checkBoxesContainer.at(j)->setCheckState(checkBoxesContainer.at(std::min(i,lastPressedCBox)).checkState());
    }
    lastPressedCBox=i;
});
