AppearanceObject.GetBackBrush(GraphicsCache) Method

Gets the solid brush used to draw the element’s background.

Namespace: DevExpress.Utils

Assembly: DevExpress.Utils.v19.2.dll

Declaration

C#

public Brush GetBackBrush(
    GraphicsCache cache
)

VB.NET

Public Function GetBackBrush(
    cache As GraphicsCache
) As Brush

Parameters

Name	Type	Description
cache	GraphicsCache	A GraphicsCache object that provides access to the pens and brushes used for painting.

Returns

Type	Description
Brush	A Brush descendant representing the brush specified by the appearance object’s settings.

Remarks

If the cache parameter’s value is not a null reference, the GetBackBrush method uses the GraphicsCache object to obtain the solid brush whose color is specified by the background color settings of the current appearance object. This lets you obtain the brush quicker as it may already be stored within a cache. Otherwise, a new System.Drawing.SolidBrush object with appropriate settings is created and returned.

Use the AppearanceObject.GetBackColor method to obtain the background color specified by the appearance object’s settings.
