== KWin::Toplevel ==
== Global ==
Toplevel is an abstract base class for all "Windows". You cannot use it directly, but everything available on Toplevel is available on Client, too.
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. Scripts can also add "X-KWin-Border-Activate" to their metadata file to have the effect listed in the screen edges KCM. This will write an entry BorderConfig= in the script configuration object with a list of ScreenEdges the user has selected.
* ''bool'' '''unregisterScreenEdge(ElectricBorder border)''': Unregisters the callback for the screen edge. This will disconnect all callbacks from this script to that edge.
* ''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*/}

'''Inherits:''' KWin::Toplevel
==== FocusPolicy ====
   
* '''ClickToFocus''': Clicking into a window activates it. This is also the default.
* '''FocusFollowsMouse''': Moving the mouse pointer actively onto a normal window activates it. For convenience, the desktop and windows on the dock are excluded. They require clicking.
* '''FocusUnderMouse''': The window that happens to be under the mouse pointer becomes active. The invariant is: no window can have focus that is not under the mouse. This also means that Alt-Tab won't work properly and popup dialogs are usually unsable with the keyboard. Note that the desktop and windows on the dock are excluded for convenience. They get focus only when clicking on it.
* '''FocusStrictlyUnderMouse''': This is even worse than FocusUnderMouse. Only the window under the mouse pointer is active. If the mouse points nowhere, nothing has the focus. If the mouse points onto the desktop, the desktop has focus. The same holds for windows on the dock.

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. Scripts can also add "X-KWin-Border-Activate" to their metadata file to have the effect listed in the screen edges KCM. This will write an entry BorderConfig= in the script configuration object with a list of ScreenEdges the user has selected.
  • bool unregisterScreenEdge(ElectricBorder border): Unregisters the callback for the screen edge. This will disconnect all callbacks from this script to that edge.
  • 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*/}

KWin::Options

Enums

FocusPolicy

  • ClickToFocus: Clicking into a window activates it. This is also the default.
  • FocusFollowsMouse: Moving the mouse pointer actively onto a normal window activates it. For convenience, the desktop and windows on the dock are excluded. They require clicking.
  • FocusUnderMouse: The window that happens to be under the mouse pointer becomes active. The invariant is: no window can have focus that is not under the mouse. This also means that Alt-Tab won't work properly and popup dialogs are usually unsable with the keyboard. Note that the desktop and windows on the dock are excluded for convenience. They get focus only when clicking on it.
  • FocusStrictlyUnderMouse: This is even worse than FocusUnderMouse. Only the window under the mouse pointer is active. If the mouse points nowhere, nothing has the focus. If the mouse points onto the desktop, the desktop has focus. The same holds for windows on the dock.

Signals

  • opacityChanged(KWin::Toplevel *toplevel, qreal oldOpacity)
  • damaged(KWin::Toplevel *toplevel, const QRegion &damage)
  • inputTransformationChanged()
