Remarks

Use the BgAlphaBlend function to obtain the starting alpha blending value of the group background. This value is specified by the style applied to the group. Group background style can be specified for all groups via the OptionsStyle.DefaultStyles.GroupBackground default style. Individual groups can override these settings by assigning a custom style to the CustomStyles.Background property of the group. The BgAlphaBlend function returns the AlphaBlending property value of the style assigned.

The BgAlphaBlend function can be used when handling the OnCustomDraw.GroupClientBackground event. It is useful if you don’t want to use custom alpha components of colors.
