## Detailed Description

Class to encapsulate user-driven action or event.

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 `paste` the contents of the clipboard or `scroll` `down` a document or `quit` the application. These are all `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 `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 would 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 `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 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 );
     }

General Usage:

The steps to using actions are roughly as follows

- Decide which attributes you want to associate with a given action (icons, text, keyboard shortcut, etc)
- Create the action using KAction (or derived or super class).
- "Plug" the Action into whatever GUI element you want. Typically, this will be a menu or toolbar.

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.

Do not delete a KAction object without unplugging it from all its containers. The simplest way to do that is to use the unplugAll() as in the following example:

     newAct->unplugAll();
     delete newAct;

Normally you will not need to do this as KActionCollection manages everything for you.

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 KStdAction class rather than defining your own.

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 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.

## Constructor & Destructor Documentation

KAction::KAction | ( | const QString & | text,
|  | const KShortcut & | cut,
|  | const QObject * | receiver,
|  | const char * | slot,
|  | KActionCollection * | parent,
|  | const char * | name
| ) |

Constructs an action with text, potential keyboard shortcut, and a SLOT to call when this action is invoked by the user.

If you do not want or have a keyboard shortcut, set the `cut` param to 0.

This is the most common KAction used when you do not have a corresponding icon (note that it won't appear in the current version of the "Edit ToolBar" dialog, because an action needs an icon to be plugged in a toolbar...).

Parameters:

  | text | The text that will be displayed.
  | cut | The corresponding keyboard shortcut.
  | receiver | The SLOT's parent.
  | slot | The SLOT to invoke to execute this action.
  | parent | This action's parent.
  | name | An internal name for this action.

Definition at line 113 of file kaction.cpp.

KAction::KAction | ( | const QString & | text,

|  | const KShortcut & | cut,
|  | const QObject * | receiver,
|  | const char * | slot,
|  | KActionCollection * | parent,
|  | const char * | name
| ) |

Constructs an action with text, icon, potential keyboard shortcut, and a SLOT to call when this action is invoked by the user.

If you do not want or have a keyboard shortcut, set the `cut` param to 0.

This is the other common KAction used. Use it when you `do` have a corresponding icon.

Parameters:

  | text | The text that will be displayed.
  | pix | The icon to display.
  | cut | The corresponding keyboard shortcut.
  | receiver | The SLOT's parent.

|  | KActionCollection * | parent,
|  | const char * | name
| ) |

Constructs an action with text, icon, potential keyboard shortcut, and a SLOT to call when this action is invoked by the user.

The icon is loaded on demand later based on where it is plugged in.

If you do not want or have a keyboard shortcut, set the `cut` param to 0.

This is the other common KAction used. Use it when you `do` have a corresponding icon.

Parameters:

  | text | The text that will be displayed.
  | pix | The icon to display.
  | cut | The corresponding keyboard shortcut (shortcut).
  | receiver | The SLOT's parent.
  | slot | The SLOT to invoke to execute this action.

| ) |

The same as the above constructor, but with a KGuiItem providing the text and icon.

Parameters:

  | item | The KGuiItem with the label and (optional) icon.
  | cut | The corresponding keyboard shortcut (shortcut).
  | receiver | The SLOT's parent.
  | slot | The SLOT to invoke to execute this action.

## Member Function Documentation

int KAction::plug | ( | QWidget * | widget,
|  | int | index = `-1`
| ) | `[virtual]`

"Plug" or insert this action into a given widget.

This will typically be a menu or a toolbar. From this point on, you will never need to directly manipulate the item in the menu or toolbar. You do all enabling/disabling/manipulation directly with your KAction object.

Parameters:

  | widget | The GUI element to display this action
  | index | The position into which the action is plugged. If this is negative, the action is inserted at the end.

Deprecated:
  . Shouldn't be used. No substitute available.

"Plug" or insert this action into a given KAccel.

Parameters:

void KAction::unplug | ( | QWidget * | w | ) | `[virtual]`

"Unplug" or remove this action from a given widget.

This will typically be a menu or a toolbar. This is rarely used in "normal" application. Typically, it would be used if your application has several views or modes, each with a completely different menu structure. If you simply want to disable an action for a given period, use setEnabled() instead.

Parameters:

  | w | Remove the action from this GUI element.

int KAction::getToolButtonID | ( |  | ) | `[static]`

How it works.

KActionCollection is an organizing container for KActions. KActionCollection keeps track of the information necessary to handle configuration and shortcuts.

Focus Widget pointer: This is the widget which is the focus for action shortcuts. It is set either by passing a QWidget* to the KActionCollection constructor or by calling setWidget() if the widget wasn't known when the object was initially constructed (as in KXMLGUIClient and KParts::PartBase)

Shortcuts: An action's shortcut will not not be connected unless a focus widget has been specified in KActionCollection.

XML Filename: This is used to save user-modified settings back to the *ui.rc file. It is set by KXMLGUIFactory.

void KAction::setWhatsThis | ( | const QString & | text | ) | `[virtual, slot]`

| Sets the What's this text for the action. This text will be displayed when a widget that has been created by plugging this action into a container is clicked on in What's this mode.

void KAction::setToolTip | ( | const QString & |  | ) | `[virtual, slot]`

Sets the tooltip text for the action.

This will be used as a tooltip for a toolbar button, as a statusbar help-text for a menu item, and it also appears in the toolbar editor, to describe the action.

For the tooltip to show up on the statusbar you will need to connect a couple of the actionclass signals to the toolbar. The easiest way of doing this is in your main window class, when you create a statusbar. See the KActionCollection class for more details.

void KAction::activated | ( | KAction::ActivationReason | reason,

This signal allows to know the reason why an action was activated: whether it was due to a toolbar button, popupmenu, keyboard accel, or programmatically.

In the first two cases, it also allows to know which mouse button was used (Left or Middle), and whether keyboard modifiers were pressed (e.g. CTRL).

Note that this signal is emitted before the normal activated() signal. Yes, BOTH signals are always emitted, so that connecting to activated() still works.
