Global

Methods and properties added to the global JavaScript object.

Read-only Properties

• KWin::Options options: Global property to all configuration values of KWin core.
• KWin::Workspace workspace: Global property to the core wrapper of KWin.
• object KWin: Provides access to enums defined in KWin::WorkspaceWrapper

Functions

• print(QVariant ... values): Prints all provided values to kDebug and as a D-Bus signal
• QVariant readConfig(QString key, QVariant defaultValue = QVariant()): Reads the config value for key in the Script's configuration with the optional default value. If not providing a default value and no value stored in the configuration an undefined value is returned.
• bool registerScreenEdge(ElectricBorder border, QScriptValue callback): Registers the callback for the screen edge. When the mouse gets pushed against the given edge the callback will be invoked.
• bool registerShortcut(QString title, QString text, QString keySequence, QScriptValue callback): Registers keySequence as a global shortcut. When the shortcut is invoked the callback will be called. Title and text are used to name the shortcut and make it available to the global shortcut configuration module.
• bool assert(bool value, QString message = QString()): Aborts the execution of the script if value does not evaluate to true. If message is provided an error is thrown with the given message, if not provided an error with default message is thrown.
• bool assertTrue(bool value, QString message = QString()): Aborts the execution of the script if value does not evaluate to true. If message is provided an error is thrown with the given message, if not provided an error with default message is thrown.
• bool assertFalse(bool value, QString message = QString()): Aborts the execution of the script if value does not evaluate to false. If message is provided an error is thrown with the given message, if not provided an error with default message is thrown.
• bool assertEquals(QVariant expected, QVariant actual, QString message = QString()): Aborts the execution of the script if the actual value is not equal to the expected value. If message is provided an error is thrown with the given message, if not provided an error with default message is thrown.
• bool assertNull(QVariant value, QString message = QString()): Aborts the execution of the script if value is not null. If message is provided an error is thrown with the given message, if not provided an error with default message is thrown.
• bool assertNotNull(QVariant value, QString message = QString()): Aborts the execution of the script if value is null. If message is provided an error is thrown with the given message, if not provided an error with default message is thrown.
• callDBus(QString service, QString path, QString interface, QString method, QVariant arg..., QScriptValue callback = QScriptValue()): Call a D-Bus method at (service, path, interface and method). A variable number of arguments can be added to the method call. The D-Bus call is always performed in an async way invoking the callback provided as the last (optional) argument. The reply values of the D-Bus method call are passed to the callback.
• registerUserActionsMenu(QScriptValue callback): Registers the passed in callback to be invoked whenever the User actions menu (Alt+F3 or right click on window decoration) is about to be shown. The callback is invoked with a reference to the Client for which the menu is shown. The callback can return either a single menu entry to be added to the menu or an own sub menu with multiple entries. The object for a menu entry should be {title: "My Menu entry", checkable: true, checked: false, triggered: function (action) { // callback with triggered QAction}}, for a menu it should be {title: "My menu", items: [{...}, {...}, ...] /*list with entries as described*/}

Read-only Properties

• bool active: Whether this Client is active or not. Use Workspace::activateClient() to activate a Client. Workspace::activateClient
• QString caption: The Caption of the Client. Read from WM_NAME property together with a suffix for hostname and shortcut. To read only the caption as provided by WM_NAME, use the getter with an additional false value.
• bool closeable: Whether the window can be closed by the user. The value is evaluated each time the getter is called. Because of that no changed signal is provided.
• bool fullScreenable: Whether the Client can be set to fullScreen. The property is evaluated each time it is invoked. Because of that there is no notify signal.
• bool maximizable: Whether the Client can be maximized both horizontally and vertically. The property is evaluated each time it is invoked. Because of that there is no notify signal.
• bool minimizable: Whether the Client can be minimized. The property is evaluated each time it is invoked. Because of that there is no notify signal.
• bool modal: Whether the Client represents a modal window.
• bool moveable: Whether the Client is moveable. Even if it is not moveable, it might be possible to move it to another screen. The property is evaluated each time it is invoked. Because of that there is no notify signal. moveableAcrossScreens
• bool moveableAcrossScreens: Whether the Client can be moved to another screen. The property is evaluated each time it is invoked. Because of that there is no notify signal. moveable
• bool providesContextHelp: Whether the Client provides context help. Mostly needed by decorations to decide whether to show the help button or not.Returns whether the window provides context help or not. If it does, you should show a help menu item or a help button like '?' and call contextHelp() if this is invoked.contextHelp()
• bool resizeable: Whether the Client can be resized. The property is evaluated each time it is invoked. Because of that there is no notify signal.
• bool shadeable: Whether the Client can be shaded. The property is evaluated each time it is invoked. Because of that there is no notify signal.
• bool transient: Whether the Client is a transient Window to another Window. transientFor
• KWin::Client transientFor: The Client to which this Client is a transient if any.
• QSize basicUnit: By how much the window wishes to grow/shrink at least. Usually QSize(1,1). MAY BE DISOBEYED BY THE WM! It's only for information, do NOT rely on it at all. The value is evaluated each time the getter is called. Because of that no changed signal is provided.
• bool move: Whether the Client is currently being moved by the user. Notify signal is emitted when the Client starts or ends move/resize mode.
• bool resize: Whether the Client is currently being resized by the user. Notify signal is emitted when the Client starts or ends move/resize mode.
• QRect iconGeometry: The optional geometry representing the minimized Client in e.g a taskbar. See _NET_WM_ICON_GEOMETRY at http://standards.freedesktop.org/wm-spec/wm-spec-latest.html . The value is evaluated each time the getter is called. Because of that no changed signal is provided.
• bool specialWindow: Returns whether the window is any of special windows types (desktop, dock, splash, ...), i.e. window types that usually don't have a window frame and the user does not use window management (moving, raising,...) on them. The value is evaluated each time the getter is called. Because of that no changed signal is provided.
• bool wantsInput: Whether the Client can accept keyboard focus. The value is evaluated each time the getter is called. Because of that no changed signal is provided.
• QPixmap icon
• KWin::TabGroup tabGroup: The "Window Tabs" Group this Client belongs to.
• bool isCurrentTab: Whether this Client is the currently visible Client in its Client Group (Window Tabs). For change connect to the visibleChanged signal on the Client's Group.
• QSize minSize: Minimum size as specified in WM_NORMAL_HINTS
• QSize maxSize: Maximum size as specified in WM_NORMAL_HINTS
• bool decorationHasAlpha: Whether the decoration is currently using an alpha channel.

Read-write Properties

• int desktop: The desktop this Client is on. If the Client is on all desktops the property has value -1.Returns the virtual desktop within the workspace() the client window is located in, 0 if it isn't located on any special desktop (not mapped yet), or NET::OnAllDesktops. Do not use desktop() directly, use isOnDesktop() instead.
• bool onAllDesktops: Whether the Client is on all desktops. That is desktop is -1.
• bool fullScreen: Whether this Client is fullScreen. A Client might either be fullScreen due to the _NET_WM property or through a legacy support hack. The fullScreen state can only be changed if the Client does not use the legacy hack. To be sure whether the state changed, connect to the notify signal.
• QRect geometry: The geometry of this Client. Be aware that depending on resize mode the geometryChanged signal might be emitted at each resize step or only at the end of the resize operation.
• bool keepAbove: Whether the Client is set to be kept above other windows.
• bool keepBelow: Whether the Client is set to be kept below other windows.
• bool minimized: Whether the Client is minimized.
• bool shade: Whether the Client is shaded.
• bool skipSwitcher: Whether the Client should be excluded from window switching effects.
• bool skipTaskbar: Indicates that the window should not be included on a taskbar.
• bool skipPager: Indicates that the window should not be included on a Pager.
• bool noBorder: Whether the window has a decoration or not. This property is not allowed to be set by applications themselves. The decision whether a window has a border or not belongs to the window manager. If this property gets abused by application developers, it will be removed again.
• bool demandsAttention: Whether window state _NET_WM_STATE_DEMANDS_ATTENTION is set. This state indicates that some action in or with the window happened. For example, it may be set by the Window Manager if the window requested activation but the Window Manager refused it, or the application may set it if it finished some work. This state may be set by both the Client and the Window Manager. It should be unset by the Window Manager when it decides the window got the required attention (usually, that it got activated).
• bool blocksCompositing: A client can block compositing. That is while the Client is alive and the state is set, Compositing is suspended and is resumed when there are no Clients blocking compositing any more.This is actually set by a window property, unfortunately not used by the target application group. For convenience it's exported as a property to the scripts.Use with care!
