Description

The documentation of the signals returned WAbstractToolButton::checked() und WAbstractToolButton::unChecked() clearly states that these signals are only emitted when the user checks the button. But the same documentation also promises "You can use the changed() signal to react to any change of the button state".

However, this signal is not emitted when toggling a check box programmatically (see minimal example attached).

I think "any" in this context refers to both checked and unchecked.

Target version set to future

It's indeed not intended to be emitted by programmatic changes. None of the event signals are. We could amend the documentation to make that a bit more clear.
