A wrapper to define the shadow around the Decoration.
The shadow around the Decoration should not be rendered as part of the Decoration. Instead a DecorationShadow should be used. That way a backend can optimize the rendering of the shadow in a better way. If the shadow were part of the Decoration directly it would need to be updated when the rendering changes. By using a dedicated DecorationShadow the same shadow can be shared between multiple DecoratedWindows.
The DecorationShadow consists of a shadow QImage which is composed of multiple parts:
- topLeft: rendered as it is
- top: stretched in x direction
- topRight: rendered as it is
- right: stretched in y direction
- bottomRight: rendered as it is
- bottom: stretched in x direction
- bottomLeft: rendered as it is
- left: stretched in y direction
The sizes of these parts is denoted in the property innerShadowRect and the layout is the following: #######################################
topLeft # top # topRight
#######################################
left # # right
#######################################
bottomLeft # bottom # bottomRight
#######################################
The innerShadowRect property is a QRect of the geometry of the areas not covered by any of the elements. This means that:
- x/y of the rect is the same as the size of the topLeft element
- width of the rect is the same as the width of the top and bottom element
- height of the rect is the same as the height of the left and the right element By that the actual sizes of all elements can be derived out of the size of the shadow image and the innerShadowRect.
The position of the rendering depends on the values;
- paddingTop
- paddingRight
- paddingBottom
- paddingLeft
The top left element is rendered with an offset of paddingLeft and paddingTop. The non-stretched elements are rendered in the size as specified, the area between two non-stretched elements (e.g. between topLeft and topRight) is filled by the element with one direction stretched and the other direction fixed at the corresponding padding value. E.g. the top element is stretched in x direction and fixed at paddingTop value. If stretching the side elements is not wanted one needs to provide a shadow image with those elements at a size that stretching is not required.
If the padding values are smaller than the sizes of the shadow elements the shadow will overlap with the Decoration and be rendered behind the Decoration.
