Document that WRadioButton does not emit unChecked
WRadioButton A is checked, and the user clicks on another
WRadioButton B in the same
WButtonGroup, this will emit
WAbstractToggleButton::checked() for B, but not
unChecked() for A.
This was an observation made by Stefan on the forum: https://redmine.emweb.be/boards/2/topics/17259
This is a consequence of the fact that the browser only emits the
change event for the radio button that was clicked, not the one that is now automatically unchecked as a result.
I also looked at Qt's behavior:
- clicked is emitted only for the one that has been clicked
- toggled is emitted whenever the checked state changes
Since it's not straightforward to make
EventSignal), and since this would be a change in existing behavior we should simply add some documentation to clarify that
unChecked will not be emitted, and suggest using
