QGraphicsDropShadowEffect ¶

概要 ¶

详细描述 ¶

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() 函数。

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.
