ID2D1RenderTarget::FillRoundedRectangle methods

Paints the interior of the specified rounded rectangle.

Overload list

MethodDescription
FillRoundedRectangle(D2D1_ROUNDED_RECT&,ID2D1Brush*)

Paints the interior of the specified rounded rectangle.

FillRoundedRectangle(D2D1_ROUNDED_RECT*,ID2D1Brush*)

Paints the interior of the specified rounded rectangle.

Remarks

This method doesn't return an error code if it fails. To determine whether a drawing operation (such as FillRoundedRectangle) failed, check the result returned by the ID2D1RenderTarget::EndDraw or ID2D1RenderTarget::Flush methods.

Examples

The following example uses the DrawRoundedRectangle and FillRoundedRectangle methods to outline and fill a rounded rectangle. This example produces the output shown in the following illustration.
