Function Documentation
◆ enableBackgroundContrast()
KWINDOWSYSTEM_EXPORT void KWindowEffects::enableBackgroundContrast | ( | QWindow * | window, |
bool | enable = true, | ||
qreal | contrast = 1, | ||
qreal | intensity = 1, | ||
qreal | saturation = 1, | ||
const QRegion & | region = QRegion() ) |
Instructs the window manager to modify the color of the background in the specified region behind the given window, in order to improve the contrast and readability of any text in the translucent window.
The given region will overwrite any previous backgroundcontrast region. Passing a null region will enable the blur effect for the whole window. The region is relative to the top-left corner of the client area.
If enable is false
, blur will be disabled for the whole window (region is ignored).
Note that you will usually want to set the region to the shape of the window, excluding any shadow or halo.
- Parameters
-
window The window for which to enable the background contrast effect enable Enable the effect if true
, disable it iffalse
brightness How to modify the area brightness: from 0 (make it black) to 2 (make it white), 1 leaves it unchanged region The region within the window where the background will be modified, specified in logical pixels

◆ enableBlurBehind()
KWINDOWSYSTEM_EXPORT void KWindowEffects::enableBlurBehind | ( | QWindow * | window, |
bool | enable = true, | ||
const QRegion & | region = QRegion() ) |
Instructs the window manager to blur the background in the specified region behind the given window.
The given region will overwrite any previous blur-behind region. Passing a null region will enable the blur effect for the whole window. The region is relative to the top-left corner of the client area.
If enable is false
, blur will be disabled for the whole window (region is ignored).
Note that you will usually want to set the region to the shape of the window, excluding any shadow or halo.
- Parameters
-
window The window for which to enable the blur effect enable Enable the effect if true
, disable it iffalse
region The region within the window where the background will be blurred, specified in logical pixels

◆ isEffectAvailable()
KWINDOWSYSTEM_EXPORT bool KWindowEffects::isEffectAvailable | ( | Effect | effect | ) |
- Returns
- if an atom property is available
- Parameters
-
effect the effect we want to check

◆ slideWindow()
KWINDOWSYSTEM_EXPORT void KWindowEffects::slideWindow | ( | QWindow * | window, |
SlideFromLocation | location, | ||
int | offset = -1 ) |
Mark a window as sliding from screen edge.
- Parameters
-
id of the window on which we want to apply the effect location edge of the screen from which we want the sliding effect. Desktop and Floating won't have effect. offset distance in pixels from the screen edge defined by location
