Detailed Description

This item exposes various properties of KWindowSystem for use inside a QML environment.

Example usage:

import org.kde.kwindowsystem 1.0

KWindowSystem {
    id: kwindowsystem
}

Rectangle {
    width: 50
    height: 50
    color: "blue"
    opacity: kwindowsystem.compositingActive ? 0.5 : 1
}

Label {
    text: i18n("You are currently on Desktop '%1'", kwindowsystem.currentDesktopName)
}

Note

The features provided by this item are specific to the windowing system and might not be supported on any platform other than X11

This property is updated delayed

Definition at line 79 of file kwindowsystemproxy.h.

int KWindowSystemProxy::currentDesktop

readwrite

The number of the current desktop.

Definition at line 61 of file kwindowsystemproxy.h.

QString KWindowSystemProxy::currentDesktopName

read

The name of the current desktop.

Definition at line 65 of file kwindowsystemproxy.h.

Member Function Documentation

QString KWindowSystemProxy::desktopName

(

int

desktop

)

const

Returns the name of the specified desktop.

See also

currentDesktopName

Parameters

desktop

the number of the desktop

Returns

the name of the desktop

Definition at line 143 of file kwindowsystemproxy.cpp.

void KWindowSystemProxy::forceActivateWindow	(	QWindow *	window,
		long	time = 0
	)

Sets window window to be the active window.

Note

This should be called only in special cases, applications shouldn't force themselves or other windows to be the active window. Generally, this call should used only by pagers and similar tools.

Parameters

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

Definition at line 115 of file kwindowsystemproxy.cpp.

bool KWindowSystemProxy::hasWindow

(

QWindow *

window

)

const

Test to see if window still managed at present.

Parameters

window

the window to test

Definition at line 106 of file kwindowsystemproxy.cpp.

void KWindowSystemProxy::setDesktopName	(	int	desktop,
		const QString &	name
	)

Sets the name of the specified desktop.

Parameters

desktop	the number of the desktop
name	the new name for the desktop

Definition at line 148 of file kwindowsystemproxy.cpp.

void KWindowSystemProxy::setOnActivities	(	QWindow *	window,
		const QStringList &	activities
	)

Moves window window to activities activities.

Parameters

window	the window
activities	the list of activity UUIDs

Definition at line 136 of file kwindowsystemproxy.cpp.

void KWindowSystemProxy::setOnAllDesktops	(	QWindow *	window,
		bool	onAllDesktops
	)

Sets window window to be present on all virtual desktops if onAllDesktops true.

Otherwise the window lives only on one single desktop.

Parameters

window	the window
onAllDesktops	true to show the window on all desktops, false otherwise

Definition at line 122 of file kwindowsystemproxy.cpp.

void KWindowSystemProxy::setOnDesktop	(	QWindow *	window,
		int	desktop
	)

Moves window window to desktop desktop.

Parameters

window	the window
desktop	the number of the new desktop
