/**
|
|
* Easy updating of menu accels when changing a TDEAccel object.
|
|
*
|
|
* Since a TDEAccel object does not keep track of menu items to which it
|
|
* is connected, we normally have to manually call
|
|
* TDEAccel::changeMenuAccel() again for each update of the TDEAccel object.
|
|
*
|
|
* With TDEAccelMenuWatch you provide the tdeaccel object and the menu
|
|
* items to which it connects, and if you update the tdeaccel you just have
|
|
* to call TDEAccelMenuWatch::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 TDEAccelMenuWatch::updateMenus() after you
|
|
* connect the * accelerators, as they are not activated till then.
