示例

 

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

' The following example creates a SolidBrush object, checks the type of the object, and

' then, if the type is BrushTypeSolidColor, uses the brush to fill a rectangle.

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

SUB Example_GetType (BYVAL hdc AS HDC)

 

  ' // Create a graphics object from the window device context

  DIM graphics AS CGpGraphics = hdc

  ' // Get the DPI scaling ratio

  DIM rxRatio AS SINGLE = graphics.GetDpiX / 96

  DIM ryRatio AS SINGLE = graphics.GetDpiY / 96

  ' // Set the scale transform

  graphics.ScaleTransform(rxRatio, ryRatio)

 

  ' // Create a SolidBrush object

  DIM solidBrush AS CGpSolidBrush = GDIP_ARGB(255, 0, 0, 255)

 

  ' // Get the type of solidBrush

  DIM nType AS BrushType = solidBrush.GetType

 

  ' // If the type of solidBrush is BrushTypeSolidColor, use it to fill a rectangle

  IF nType = BrushTypeSolidColor THEN

     graphics.FillRectangle(@solidBrush, 0, 0, 100, 100)

  END IF

 

END SUB
