Detailed Description¶

A drop shadow effect renders the source with a drop shadow. The color of the drop shadow can be modified using the setColor() function. The drop shadow offset can be modified using the setOffset() function and the blur radius of the drop shadow can be changed with the setBlurRadius() function.

By default, the drop shadow is a semi-transparent dark gray (QColor(63, 63, 63, 180)) shadow, blurred with a radius of 1 at an offset of 8 pixels towards the lower right. The drop shadow offset is specified in device coordinates.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property blurRadiusᅟ: float¶

This property holds the blur radius in pixels of the drop shadow..

Using a smaller radius results in a sharper shadow, whereas using a bigger radius results in a more blurred shadow.

By default, the blur radius is 1 pixel.

Access functions:

blurRadius()
setBlurRadius()
Signal blurRadiusChanged()

property colorᅟ: QColor¶

This property holds the color of the drop shadow..

By default, the drop color is a semi-transparent dark gray (QColor(63, 63, 63, 180)).

setColor()
Signal colorChanged()

property offsetᅟ: QPointF¶

This property holds the shadow offset in pixels..

By default, the offset is 8 pixels towards the lower right.

The offset is given in device coordinates, which means it is unaffected by scale.
