Background of DGKC Window
By default window of a DGKC component is created with a flat color
background defined by the BackColor Windows Forms control property.
DGKC can also display gradient colors of
various directions and configuration. To enable gradient background query
IContext_DG
from IView_DG
of the component and set the first (id=0) integer parameter to 1. To disable
gradient background set the parameter to 0. See
DIView sample for an example.
Gradient color of the window is defined by array of colors positioned
along the edge of the component window. The array of color has always at
least four colors for the corners. For example, to make the background
horizontally gradient changing from blue to green set colors at two left
corners to blue and colors at two right hand corners to green. Adding colors
in the middle of window sides will make the background more complicated.
Colors of the components background can be manipulated with
IRectangleColor_DG
interface obtained via query: DGKC > GetView
> IView_DG >
IRectangleColor_DG
