When you usually think of effects such as blur, contrast, and glow, you might think of image editing software, as they tend to be applied those effects to images. Qt Graphical Effects can apply those same types of effects to QML UI components.
If you use the Qt Quick Scene Graph software renderer, these will not be available or usable, as this does not support the effects.
Qt Graphical Effects come in a variety of types, each with various sub-effects:
Blend
Color
:BrightnessContrast
ColorOverlay
Colorize
Desaturate
GammaAdjust
HueSaturation
LevelAdjust
Gradients
:ConicalGradient
LinearGradient
RadialGradient
Displace
DropShadows
:DropShadow
InnerShadow
Blurs
:FastBlur
GaussianBlur
MaskedBlur
RecursiveBlur
MotionBlurs
:DirectionalBlur
RadialBlur
ZoomBlur
Glows
:Glow
RectangularGlow
Masks
:OpacityMask
ThresholdMask
Now, let's move on to how DropShadow
, being one of the mostuseful effects, works.
