Detailed Description

A container for a set of QAction objects.

KActionCollection manages a set of QAction objects. It allows them to be grouped for organized presentation of configuration to the user, saving + loading of configuration, and optionally for automatic plugging into specified widget(s).

Additionally, KActionCollection provides several convenience functions for locating named actions, and actions grouped by QActionGroup.

Note

If you create your own action collection and need to assign shortcuts to the actions within, you have to call associateWidget() or addAssociatedWidget() to have them working.

QAction * KActionCollection::action

(

const QString &

name

)

const

Get the action with the given name from the action collection.

Parameters

name	Name of the KAction

Returns

A pointer to the KAction in the collection which matches the parameters or null if nothing matches.

Definition at line 131 of file kactioncollection.cpp.

const QList< QActionGroup * > KActionCollection::actionGroups

(

)

const

Returns the list of all QActionGroups associated with actions in this action collection.

Definition at line 200 of file kactioncollection.cpp.

QT_MOC_COMPAT void KActionCollection::actionHighlighted ( QAction *  action )

signal

Indicates that action was highlighted (hovered over).

Deprecated:

Replaced by actionHovered(QAction* action);

void KActionCollection::actionHovered ( QAction *  action )

signal

Indicates that action was hovered.

QList< QAction * > KActionCollection::actions

(

)

const

Returns the list of KActions which belong to this action collection.

The list is guaranteed to be in the same order the action were put into the collection.

Definition at line 186 of file kactioncollection.cpp.

const QList< QAction * > KActionCollection::actionsWithoutGroup

(

)

const

Returns the list of KActions without an QAction::actionGroup() which belong to this action collection.

Definition at line 191 of file kactioncollection.cpp.

void KActionCollection::actionTriggered ( QAction *  action )

signal

Indicates that action was triggered.

template<class ActionType >

ActionType* KActionCollection::add ( const QString &  name, const QObject *  receiver = 0, const char *  member = 0  )

inline

Creates a new action under the given name, adds it to the collection and connects the action's triggered(bool) signal to the specified receiver/member.

The receiver slot may accept either a bool or no parameters at all (i.e. slotTriggered(bool) or slotTriggered() ). The type of the action is specified by the template parameter ActionType.

NOTE: KDE prior to 4.2 connected the triggered() signal instead of the triggered(bool) signal.

Parameters

name	The internal name of the action (e.g. "file-open").
receiver	The QObject to connect the triggered(bool) signal to. Leave 0 if no connection is desired.
member	The SLOT to connect the triggered(bool) signal to. Leave 0 if no connection is desired.

Returns

new action of the given type ActionType.

Definition at line 412 of file kactioncollection.h.

QAction * KActionCollection::addAction	(	const QString &	name,
		QAction *	action
	)

Add an action under the given name to the collection.

Inserting an action that was previously inserted under a different name will replace the old entry, i.e. the action will not be available under the old name anymore but only under the new one.

Inserting an action under a name that is already used for another action will replace the other action in the collection (but will not delete it).

Parameters

name	The name by which the action be retrieved again from the collection.
action	The action to add.

Returns

the same as the action given as parameter. This is just for convenience (chaining calls) and consistency with the other addAction methods, you can also simply ignore the return value.

Definition at line 217 of file kactioncollection.cpp.

KAction * KActionCollection::addAction	(	const QString &	name,
		KAction *	action
	)

Definition at line 209 of file kactioncollection.cpp.

KAction * KActionCollection::addAction	(	KStandardAction::StandardAction	actionType,
		const QObject *	receiver = 0,
		const char *	member = 0
	)

Creates a new standard action, adds it to the collection and connects the action's triggered(bool) signal to the specified receiver/member.

The newly created action is also returned.

Note: Using KStandardAction::OpenRecent will cause a different signal than triggered(bool) to be used, see KStandardAction for more information.

The action can be retrieved later from the collection by its standard name as per KStandardAction::stdName.

Parameters

actionType	The standard action type of the action to create.
receiver	The QObject to connect the triggered(bool) signal to. Leave 0 if no connection is desired.
member	The SLOT to connect the triggered(bool) signal to. Leave 0 if no connection is desired.

Returns

new action of the given type ActionType.

Definition at line 337 of file kactioncollection.cpp.

KAction * KActionCollection::addAction	(	KStandardAction::StandardAction	actionType,
		const QString &	name,
		const QObject *	receiver = 0,
		const char *	member = 0
	)

Creates a new standard action, adds to the collection under the given name and connects the action's triggered(bool) signal to the specified receiver/member.

The newly created action is also returned.

Note: Using KStandardAction::OpenRecent will cause a different signal than triggered(bool) to be used, see KStandardAction for more information.

The action can be retrieved later from the collection by the specified name.

Parameters

actionType	The standard action type of the action to create.
name	The name by which the action be retrieved again from the collection.
receiver	The QObject to connect the triggered(bool) signal to. Leave 0 if no connection is desired.
member	The SLOT to connect the triggered(bool) signal to. Leave 0 if no connection is desired.

Returns

new action of the given type ActionType.

Definition at line 343 of file kactioncollection.cpp.

KAction * KActionCollection::addAction	(	const QString &	name,
		const QObject *	receiver = 0,
		const char *	member = 0
	)

Creates a new action under the given name to the collection and connects the action's triggered(bool) signal to the specified receiver/member.

The newly created action is returned.

NOTE: KDE prior to 4.2 used the triggered() signal instead of the triggered(bool) signal.

Inserting an action that was previously inserted under a different name will replace the old entry, i.e. the action will not be available under the old name anymore but only under the new one.

Inserting an action under a name that is already used for another action will replace the other action in the collection.

Parameters

name	The name by which the action be retrieved again from the collection.

void KActionCollection::addAssociatedWidget

(

QWidget *

widget

)

Associate all actions in this collection to the given widget, including any actions added after this association is made.

This does not change the action's shortcut context, so if you need to have the actions only trigger when the widget has focus, you'll need to set the shortcut context on each action to Qt::WidgetShortcut (or better still, Qt::WidgetWithChildrenShortcut with Qt 4.4+)

Definition at line 708 of file kactioncollection.cpp.

const QList< KActionCollection * > & KActionCollection::allCollections ( )

(

)

const

Return a list of all associated widgets.

Definition at line 761 of file kactioncollection.cpp.

void KActionCollection::associateWidget

(

QWidget *

widget

)

const

Associate all actions in this collection to the given widget.

Unlike addAssociatedWidget, this method only adds all current actions in the collection to the given widget. Any action added after this call will not be added to the given widget automatically. So this is just a shortcut for a foreach loop and a widget->addAction call.

Definition at line 700 of file kactioncollection.cpp.

void KActionCollection::clear

(

)

Clears the entire action collection, deleting all actions.

What the function does if config is zero depends. If this action collection belongs to a KXMLGuiClient the setting are saved to the kxmlgui definition file. If not the settings are written to the applications config file.

Note

oneAction() and writeDefaults() have no meaning for the kxmlgui configuration file.

Parameters

config	Config object to save to, or null (see above)
writeDefaults	set to true to write settings which are already at defaults.
oneAction	pass an action here if you just want to save the values for one action, eg. if you know that action is the only one which has changed.
