/**
|
|
* Easy updating of menu accels when changing a KAccel object.
|
|
*
|
|
* Since a KAccel object does not keep track of menu items to which it
|
|
* is connected, we normally have to manually call
|
|
* KAccel::changeMenuAccel() again for each update of the KAccel object.
|
|
*
|
|
* With KAccelMenuWatch you provide the kaccel object and the menu
|
|
* items to which it connects, and if you update the kaccel you just have
|
|
* to call KAccelMenuWatch::updateMenus() and the menu items will be updated.
|
|
*
|
|
* It is safe to delete menus that have connections handled by this class.
|
|
* On deletion of a menu, all associated accelerators will be deleted.
|
|
*
|
|
* Note that you _have_ to call KAccelMenuWatch::updateMenus() after you
|
|
* connect the * accelerators, as they are not activated till then.
