示例

 

' ========================================================================================

' The following example sets up two hatch styles: horiz and current (initialized to

' HatchStyleDiagonalCross). A rectangle that uses horiz as the hatch style is painted.

' Then the HatchBrush.GetHatchStyle method is used to get the current hatch style of the

' brush (which at the time is HatchStyleHorizontal). The address of the current HatchStyle

' object (initialized to HatchStyleDiagonalCross) is passed as the return point for the

' call to GetHatchStyle. When the rectangle is painted again, notice that the hatch style

' is again HatchStyleHorizontal (not HatchStyleDiagonalCross). This shows that the call to

' HatchBrush.GetHatchStyle was successful.
