Detailed Description

Configurable global shortcut support.

KGlobalAccel allows you to have global accelerators that are independent of the focused window. Unlike regular shortcuts, the application's window does not need focus for them to be activated.

Autoloading

Look up the action in global settings (using its main component's name and text()) and set the shortcut as saved there.

See also: setGlobalShortcut()

NoAutoloading

Prevent autoloading of saved global shortcut for action.

Definition at line 41 of file kglobalaccel.h.

◆ MatchType

enum KGlobalAccel::MatchType

Keysequence match semantics.

Assuming we have an Emacs-style shortcut, for example (Alt+B, Alt+F, Alt+G) already assigned, how a new shortcut is compared depends on which value of the enum is used: Equal : Exact matching: (Alt+B, Alt+F, Alt+G) Shadows : Sequence shadowing: (Alt+B, Alt+F), (Alt+F, Alt+G) Shadowed : Sequence being shadowed: (Alt+B, Alt+F, Alt+G, <any key>), (<any key>, Alt+B, Alt+F, Alt+G)

Member Function Documentation

◆ cleanComponent()

bool KGlobalAccel::cleanComponent ( const QString & componentUnique )

static

Clean the shortcuts for component componentUnique.

If the component is not active all global shortcut registrations are purged and the component is removed completely.

If the component is active all global shortcut registrations not in use will be purged. If there is no shortcut registration left the component is purged too.

If a purged component or shortcut is activated the next time it will reregister itself. All you probably will lose on wrong usage are the user's set shortcuts.

If you make sure your component is running and all global shortcuts it has are active this function can be used to clean up the registry.

Handle with care!

If the method return true at least one shortcut was purged so handle all previously acquired information with care.

Definition at line 152 of file kglobalaccel.cpp.

◆ defaultShortcut()

QList< QKeySequence > KGlobalAccel::defaultShortcut ( const QAction * action ) const

Get the global default shortcut for this action, if one exists.

Global shortcuts allow your actions to respond to accellerators independently of the focused window. Unlike regular shortcuts, the application's window does not need focus for them to be activated.

See also: setDefaultShortcut()

Since: 5.0

Definition at line 626 of file kglobalaccel.cpp.

◆ globalShortcut()

QList< QKeySequence > KGlobalAccel::globalShortcut	(	const QString &	componentName,
		const QString &	actionId ) const

Retrieves the shortcut as defined in global settings by componentName (e.g.

"kwin") and actionId (e.g. "Kill Window").

Since: 5.10

Definition at line 636 of file kglobalaccel.cpp.

◆ globalShortcutChanged

void KGlobalAccel::globalShortcutChanged	(	QAction *	action,
		const QKeySequence &	seq )

signal

Emitted when the global shortcut is changed.

A global shortcut is subject to be changed by the global shortcuts kcm.

Parameters

action	pointer to the action for which the changed shortcut was registered
seq	the key sequence that corresponds to the changed shortcut

See also: setGlobalShortcut; setDefaultShortcut

Since: 5.0

◆ globalShortcutsByKey()

QList< KGlobalShortcutInfo > KGlobalAccel::globalShortcutsByKey	(	const QKeySequence &	seq,
		MatchType	type = Equal )

static

Returns a list of global shortcuts registered for the shortcut seq.

If the list contains more that one entry it means the component that registered the shortcuts uses global shortcut contexts. All returned shortcuts belong to the same component.

Parameters

type	a value from the KGlobalAccel::MatchType enum

Since: 5.90

Definition at line 520 of file kglobalaccel.cpp.

◆ hasShortcut()

bool KGlobalAccel::hasShortcut ( const QAction * action ) const

Returns true if a shortcut or a default shortcut has been registered for the given action.

Since: 5.0

Definition at line 653 of file kglobalaccel.cpp.

◆ isComponentActive()

bool KGlobalAccel::isComponentActive ( const QString & componentName )

static

Check if component is active.

Parameters

componentUnique the components unique identifier

Returns: true if active, @false if not

Definition at line 163 of file kglobalaccel.cpp.

◆ isGlobalShortcutAvailable()

bool KGlobalAccel::isGlobalShortcutAvailable	(	const QKeySequence &	seq,
		const QString &	component = QString() )

static

Check if the shortcut @seq is available for the component.

The component is only of interest if the current application uses global shortcut contexts. In that case a global shortcut by component in an inactive global shortcut contexts does not block the seq for us.

Since: 4.2

Definition at line 525 of file kglobalaccel.cpp.

◆ promptStealShortcutSystemwide()

bool KGlobalAccel::promptStealShortcutSystemwide	(	QWidget *	parent,
		const QList< KGlobalShortcutInfo > &	shortcuts,
		const QKeySequence &	seq )

static

Show a messagebox to inform the user that a global shortcut is already occupied, and ask to take it away from its current action(s).

This is GUI only, so nothing will be actually changed.

See also: stealShortcutSystemwide()

Since: 4.2

Definition at line 531 of file kglobalaccel.cpp.

◆ removeAllShortcuts()

void KGlobalAccel::removeAllShortcuts ( QAction * action )

Unregister and remove all defined global shortcuts for the given action.

Since: 5.0

Definition at line 648 of file kglobalaccel.cpp.

◆ self()

KGlobalAccel * KGlobalAccel::self ( )

static

Returns (and creates if necessary) the singleton instance.

Definition at line 195 of file kglobalaccel.cpp.

◆ setDefaultShortcut()

bool KGlobalAccel::setDefaultShortcut	(	QAction *	action,
		const QList< QKeySequence > &	shortcut,
		GlobalShortcutLoading	loadFlag = Autoloading )

Assign a default global shortcut for a given QAction.

For more information about global shortcuts

See also: setShortcut Upon shortcut change the globalShortcutChanged will be triggered so other applications get notified; globalShortcutChanged

Since: 5.0

Definition at line 596 of file kglobalaccel.cpp.

◆ setGlobalShortcut() [1/2]

bool KGlobalAccel::setGlobalShortcut	(	QAction *	action,
		const QKeySequence &	shortcut )

static

Convenient method to set both active and default shortcut.

This method is suited for the case that only one shortcut is to be configured.

If more control for loading the shortcuts is needed use the variants offering more control.

See also: setShortcut; setDefaultShortcut

Since: 5.0

Definition at line 664 of file kglobalaccel.cpp.

◆ setGlobalShortcut() [2/2]

bool KGlobalAccel::setGlobalShortcut	(	QAction *	action,
		const QList< QKeySequence > &	shortcut )

static

Convenient method to set both active and default shortcut.

If more control for loading the shortcuts is needed use the variants offering more control.

See also: setShortcut; setDefaultShortcut

Since: 5.0

Definition at line 658 of file kglobalaccel.cpp.

◆ setShortcut()

bool KGlobalAccel::setShortcut	(	QAction *	action,
		const QList< QKeySequence > &	shortcut,
		GlobalShortcutLoading	loadFlag = Autoloading )

Assign a global shortcut for the given action.

Global shortcuts allow an action to respond to key shortcuts independently of the focused window, i.e. the action will trigger if the keys were pressed no matter where in the X session.

The action must have a per main component unique action->objectName() to enable cross-application bookkeeping. If the action->objectName() is empty this method will do nothing and will return false.

It is mandatory that the action->objectName() doesn't change once the shortcut has been successfully registered.

Note: KActionCollection::insert(name, action) will set action's objectName to name so you often don't have to set an objectName explicitly.

When an action, identified by main component name and objectName(), is assigned a global shortcut for the first time on a KDE installation the assignment will be saved. The shortcut will then be restored every time setGlobalShortcut() is called with loading == Autoloading.

If you actually want to change the global shortcut you have to set loading to NoAutoloading. The new shortcut will be automatically saved again.

Parameters

action	the action for which the shortcut will be assigned
shortcut	global shortcut(s) to assign. Will be ignored unless `loading` is set to NoAutoloading or this is the first time ever you call this method (see above).
loadFlag	if Autoloading, assign the global shortcut this action has previously had if any. That way user preferences and changes made to avoid clashes will be conserved. if NoAutoloading the given shortcut will be assigned without looking up old values. You should only do this if the user wants to change the shortcut or if you have another very good reason. Key combinations that clash with other shortcuts will be dropped.

Note: the default shortcut will never be influenced by autoloading - it will be set as given.

See also: shortcut(); globalShortcutChanged

Since: 5.0

Definition at line 611 of file kglobalaccel.cpp.

◆ shortcut()

QList< QKeySequence > KGlobalAccel::shortcut ( const QAction * action ) const

Get the global shortcut for this action, if one exists.

Global shortcuts allow your actions to respond to accellerators independently of the focused window. Unlike regular shortcuts, the application's window does not need focus for them to be activated.

Note: that this method only works together with setShortcut() because the action pointer is used to retrieve the result. If you would like to retrieve the shortcut as stored in the global settings, use the globalShortcut(componentName, actionId) instead.

See also: setShortcut()

Since: 5.0

Definition at line 631 of file kglobalaccel.cpp.

◆ stealShortcutSystemwide()

void KGlobalAccel::stealShortcutSystemwide ( const QKeySequence & seq )

static

Take away the given shortcut from the named action it belongs to.

This applies to all actions with global shortcuts in any KDE application.
