Detailed Description

Convenience access to certain properties and features of the window manager.

The class KWindowSystem provides information about the state of the window manager and allows asking the window manager to change them using a more high-level interface than the NETWinInfo/NETRootInfo lowlevel classes.

Because of limitiations of the way Qt is implemented on Mac OSX, the WId's returned by methods in this class are not compatible with those expected by other Qt methods. So while it should be fine to pass WId's retrieved by for example calling the winId method on a QWidget to methods in this class the reverse is not true. You should never pass a WId obtained from this class to a Qt method accepting a WId parameter.

Class for interaction with the window manager.

Member Function Documentation

void KWindowSystem::activateWindow	(	WId	win,
		long	time = `0`
	)

static

Requests that window win is activated.

There are two ways how to activate a window, by calling activateWindow() and forceActiveWindow(). Generally, applications shouldn't make attempts to explicitly activate their windows, and instead let the user to activate them. In the special cases where this may be needed, applications should use activateWindow(). Window manager may consider whether this request wouldn't result in focus stealing, which would be obtrusive, and may refuse the request.

The usage of forceActiveWindow() is meant only for pagers and similar tools, which represent direct user actions related to window manipulation. Except for rare cases, this request will be always honored, and normal applications are forbidden to use it.

In case of problems, consult the KWin README in the kdebase package (kdebase/kwin/README), or ask on the kwin@.nosp@m.kde..nosp@m.org mailing list.

Parameters

win	the id of the window to make active
time	X server timestamp of the user activity that caused this request

Definition at line 355 of file kwindowsystem_mac.cpp.

WId KWindowSystem::activeWindow ( )

static

Returns the currently active window, or 0 if no window is active.

Returns: the window id of the active window, or 0 if no window is active

Definition at line 348 of file kwindowsystem_mac.cpp.

void KWindowSystem::activeWindowChanged ( WId id )

signal

Hint that <Window> is active (= has focus) now.

Parameters

id	the id of the window that is active

bool KWindowSystem::allowedActionsSupported ( )

static

Returns true if the WM announces which actions it allows for windows.

Definition at line 597 of file kwindowsystem_mac.cpp.

void KWindowSystem::allowExternalProcessWindowActivation ( int pid = -1 )

static

Allows a window from another process to raise and activate itself.

Depending on the window manager, the grant may only be temporary, or for a single activation, and it may require the current process to be the "foreground" one" (ie. the process with the input focus).

You should call this function before executing actions that may trigger the showing of a window or dialog in another process, e.g. a dbus signal or function call, or any other inter-process notification mechanism.

This is mostly used on Windows, where windows are not allowed to be raised and activated if their process is not the foreground one, but it may also apply to other window managers.

Parameters

pid	if specified, the grant only applies to windows belonging to the specific process. By default, a value of -1 means all processes.

Definition at line 622 of file kwindowsystem_mac.cpp.

void KWindowSystem::clearState	(	WId	win,
		unsigned long	state
	)

static

Clears the state of window win from state.

Possible values are or'ed combinations of NET::Modal, NET::Sticky, NET::MaxVert, NET::MaxHoriz, NET::Shaded, NET::SkipTaskbar, NET::SkipPager, NET::Hidden, NET::FullScreen, NET::KeepAbove, NET::KeepBelow, NET::StaysOnTop

Parameters

win	the id of the window
state	the flags that will be cleared

Definition at line 512 of file kwindowsystem_mac.cpp.

bool KWindowSystem::compositingActive ( )

static

Returns true if a compositing manager is running (i.e.

ARGB windows are supported, effects will be provided, etc.).

Definition at line 379 of file kwindowsystem_mac.cpp.

void KWindowSystem::compositingChanged ( bool enabled )

signal

Compositing was enabled or disabled.

Note that this signal may be emitted before any compositing plugins have been initialized in the window manager.

If you need to check if a specific compositing plugin such as the blur effect is enabled, you should track that separately rather than test for it in a slot connected to this signal.

Since: 4.7.1

void KWindowSystem::setMainWindow	(	QWidget *	subwindow,
		WId	mainwindow
	)

static

Sets the parent window of subwindow to be mainwindow.

This overrides the parent set the usual way as the QWidget parent, but only for the window manager - e.g. stacking order and window grouping will be affected, but features like automatic deletion of children when the parent is deleted are unaffected and normally use the QWidget parent.

This function should be used before a dialog is shown for a window that belongs to another application.

signal

A window has been added.

Parameters

id	the id of the window

void KWindowSystem::windowChanged	(	WId	id,
		const unsigned long *	properties
	)

signal

The window changed.

The properties parameter contains the NET properties that were modified (see netwm_def.h). First element are NET::Property values, second element are NET::Property2 values (i.e. the format is the same like for the NETWinInfo class constructor).

Parameters

id	the id of the window
properties	the properties that were modified

void KWindowSystem::windowChanged	(	WId	id,
		unsigned int	properties
	)

signal

Deprecated:: The window changed.

The unsigned int parameter contains the NET properties that were modified (see netwm_def.h).

static

Returns information about window win.

It is recommended to check whether the returned info is valid by calling the valid() method.

Parameters

win	the id of the window

A window has been removed.

Parameters

id	the id of the window that has been removed

const QList< WId > & KWindowSystem::windows ( )

static

Returns the list of all toplevel windows currently managed by the window manager in the order of creation.

Please do not rely on indexes of this list: Whenever you enter Qt's event loop in your application, it may happen that entries are removed or added. Your module should perhaps work on a copy of this list and verify a window with hasWId() before any operations.

Iteration over this list can be done easily with

QList<WId>::ConstIterator it;
for ( it = KWindowSystem::windows().begin();
      it != KWindowSystem::windows().end(); ++it ) {
   ... do something here,  (*it) is the current WId.
     }

Returns: the list of all toplevel windows
