RecentFiles kcm: whattoremember: Make the value visible in the UI match the value saved
In this commit:
- Setting the property
kcfg_property=kcfg_value
on the QGroupBox. This should force the KConfigDialogManager to use that to retrieve that value that needs to be stored. - Introducing RecentFilesKcm::whatToRememberWidgetChanged which figures out the correct
value of "what-to-remember" and sets it under the property
kcfg_value
and triggers the Save/Reset buttons. - Linking the above slot to the
QAbstractButton::clicked
signals of the radio buttons
BUG: 397487 (cherry picked from commit 69a6228b)
