KXmlGui
Framework for managing menu and toolbar actions.
KXmlGui Introduction
KXMLGUI provides a framework for managing menu and toolbar actions in an abstract way. The actions are configured through a XML description and hooks in the application code. The framework supports merging of multiple description for example for integrating actions from plugins.
Kiosk
KXMLGui makes use of the Kiosk authorization functionality of KConfig (see the KAuthorized namespace in that framework). Notably, QAction instances added to a KActionCollection are disabled if KAuthorized::authorizeAction() reports that they are not authorized. The items on the standard help menu (KHelpMenu) can likewise be disabled based on Kiosk settings, and toolbar editing can be restricted.
See KActionCollection, KHelpMenu and KToolBar documentation for more information.
