/**
|
|
* Handle shortcuts.
|
|
*
|
|
* Allow a user to configure shortcuts
|
|
* through application configuration files or through the
|
|
* KKeyChooser GUI.
|
|
*
|
|
* A KAccel contains a list of accelerator actions.
|
|
*
|
|
* For example, CTRL+Key_P could be a shortcut for printing a document. The key
|
|
* codes are listed in tqnamespace.h. "Print" could be the action name for printing.
|
|
* The action name identifies the shortcut in configuration files and the
|
|
* KKeyChooser GUI.
|
|
*
|
|
* A KAccel object handles key events sent to its parent widget and to all
|
|
* children of this parent widget. The most recently created KAccel object
|
|
* has precedence over any KAccel objects created before it.
|
|
* When a shortcut pressed, KAccel calls the slot to which it has been
|
|
* connected. If you want to set global accelerators, independent of the window
|
|
* which has the focus, use TDEGlobalAccel.
|
|
*
|
|
* Reconfiguration of a given shortcut can be prevented by specifying
|
|
* that an accelerator item is not configurable when it is inserted. A special
|
|
* group of non-configurable key bindings are known as the
|
|
* standard accelerators.
|
|
*
|
|
* The standard accelerators appear repeatedly in applications for
|
|
* standard document actions such as printing and saving. A convenience method is
|
|
* available to insert and connect these accelerators which are configurable on
|
|
* a desktop-wide basis.
|
|
*
|
|
* It is possible for a user to choose to have no key associated with
|
|
* an action.
|
|
*
|
|
* The translated first argument for insertItem() is used only
|
|
* in the configuration dialog.
|
|
*\code
|
|
* KAccel* pAccel = new KAccel( this );
|
|
*
|
|
* // Insert an action "Scroll Up" which is associated with the "Up" key:
|
|
* pAccel->insert( "Scroll Up", i18n("Scroll up"),
|
|
* i18n("Scroll up the current document by one line."),
