How to uncheck the action on the toolbar

[Mihan]

Hi all

I found the action could not be uncheck on the tool bar.
I set QActionGroup::setExclusive(true) the put the actions into, then set QAction::setCheckable(true).

the last action can be uncheck the last action when other actions checked, but it can not be uncheck if I press the same again.

Must I make a slot to setchecked(false)?

Best regards

If you've set QActionGroup::setExclusive(true), I think even setChecked(false) won't be able to uncheck it.

Hi @Mihan,

You should probably set exclusion policy to QActionGroup::ExclusionPolicy::ExclusiveOptional

actionGroup.setExclusionPolicy(QActionGroup::ExclusiveOptional)

@Gojir4 said in How to uncheck the action on the toolbar:

QActionGroup::ExclusionPolicy::ExclusiveOptional

Thanks a lot. it seems I must upgrade the Qt to 5.14
So does it meen I must setChecked(false) by myself in lower version?
