/**
* The KAction class (and derived and super classes) provides a way to
* easily encapsulate a "real" user-selected action or event in your
* program.
*
* For instance, a user may want to @p paste the contents of
* the clipboard or @p scroll @p down a document or @p quit the
* application. These are all @p actions -- events that the
* user causes to happen. The KAction class allows the developer to
* deal with these actions in an easy and intuitive manner.
*
* Specifically, the KAction class encapsulated the various attributes
* to an event/action. For instance, an action might have an icon
* that goes along with it (a clipboard for a "paste" action or
* scissors for a "cut" action). The action might have some text to
* describe the action. It will certainly have a method or function
* that actually @p executes the action! All these attributes
* are contained within the KAction object.
*
* The advantage of dealing with Actions is that you can manipulate
* the Action without regard to the GUI representation of it. For
* instance, in the "normal" way of dealing with actions like "cut",
* you would manually insert a item for Cut into a menu and a button
* into a toolbar. If you want to disable the cut action for a moment
* (maybe nothing is selected), you woud have to hunt down the pointer
* to the menu item and the toolbar button and disable both
* individually. Setting the menu item and toolbar item up uses very
* similar code - but has to be done twice!
*
* With the Action concept, you simply "plug" the Action into whatever
* GUI element you want. The KAction class will then take care of
* correctly defining the menu item (with icons, accelerators, text,
* etc) or toolbar button.. or whatever. From then on, if you
* manipulate the Action at all, the effect will propogate through all
* GUI representations of it. Back to the "cut" example: if you want
* to disable the Cut Action, you would simply do
* 'cutAction->setEnabled(false)' and the menuitem and button would
* instantly be disabled!
*
* This is the biggest advantage to the Action concept -- there is a
* one-to-one relationship between the "real" action and @p all
* GUI representations of it.
*
* KAction emits the activated() signal if the user activated the
* corresponding GUI element ( menu item, toolbar button, etc. )
*
* If you are in the situation of wanting to map the activated()
* signal of multiple action objects to one slot, with a special
* argument bound to each action, then you might consider using
* @ref QSignalMapper . A tiny example:
*
*
* QSignalMapper *desktopNumberMapper = new QSignalMapper( this );
* connect( desktopNumberMapper, SIGNAL( mapped( int ) ),
* this, SLOT( moveWindowToDesktop( int ) ) );
*
* for ( uint i = 0; i < numberOfDesktops; ++i ) {
* KAction *desktopAction = new KAction( i18n( "Move Window To Desktop %i" ).arg( i ), ... );
* connect( desktopAction, SIGNAL( activated() ), desktopNumberMapper, SLOT( map() ) );
* desktopNumberMapper->setMapping( desktopAction, i );
* }
*
*
* @sect General Usage:
*
* The steps to using actions are roughly as follows
*
* @li Decide which attributes you want to associate with a given
* action (icons, text, keyboard shortcut, etc)
* @li Create the action using KAction (or derived or super class).
* @li "Plug" the Action into whatever GUI element you want. Typically,
* this will be a menu or toolbar.
*
* @sect Detailed Example:
*
* Here is an example of enabling a "New [document]" action
*
* KAction *newAct = new KAction(i18n("&New"), "filenew",
* KStdAccel::shortcut(KStdAccel::New),
* this, SLOT(fileNew()),
* actionCollection(), "new");
*
* This line creates our action. It says that wherever this action is
* displayed, it will use "&New" as the text, the standard icon, and
* the standard shortcut. It further says that whenever this action
* is invoked, it will use the fileNew() slot to execute it.
*
*
* QPopupMenu *file = new QPopupMenu;
* newAct->plug(file);
*
* That just inserted the action into the File menu. The point is, it's not
* important in which menu it is: all manipulation of the item is
* done through the newAct object.
*
*
* newAct->plug(toolBar());
*
* And this inserted the Action into the main toolbar as a button.
*
* That's it!
*
* If you want to disable that action sometime later, you can do so
* with
*
* newAct->setEnabled(false)
*
* and both the menuitem in File and the toolbar button will instantly
* be disabled.
*
* Note: if you are using a "standard" action like "new", "paste",
* "quit", or any other action described in the KDE UI Standards,
* please use the methods in the @ref KStdAction class rather than
* defining your own.
*
* @sect Usage Within the XML Framework:
*
* If you are using KAction within the context of the XML menu and
* toolbar building framework, then there are a few tiny changes. The
* first is that you must insert your new action into an action
* collection. The action collection (a @ref KActionCollection) is,
* logically enough, a central collection of all of the actions
* defined in your application. The XML UI framework code in KXMLGUI
* classes needs access to this collection in order to build up the
* GUI (it's how the builder code knows which actions are valid and
* which aren't).
*
* Also, if you use the XML builder framework, then you do not ever
* have to plug your actions into containers manually. The framework
* does that for you.
*
* @see KStdAction
* @short Class to encapsulate user-driven action or event
