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*/}

  • 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!

Functions

  • closeWindow(): Closes the window by either sending a delete_window message or using XKill.
  • updateCaption()
  • bool tabBefore(Client *other, bool activate)
  • bool tabBehind(Client *other, bool activate)
  • syncTabGroupFor(QString property, bool fromThisClient=false): Syncs the dynamic property fromThisClient or the to all members of the tabGroup() (if there is one) eg. if you call: client->setProperty("kwin_tiling_floats", true); client->syncTabGroupFor("kwin_tiling_floats", true) all clients in this tabGroup will have ::property("kwin_tiling_floats").toBool() == true WARNING: non dynamic properties are ignored - you're not supposed to alter/update such explicitly
  • bool untab(const QRect &toGeometry=QRect(), bool clientRemoved=false)
