IDCompositionDevice::CreateVisual method (dcomp.h)

Creates a new visual object.

Syntax

HRESULT CreateVisual(
  [out] IDCompositionVisual **visual
);

Parameters

[out] visual

Type: IDCompositionVisual**

The new visual object. This parameter must not be NULL.

Return value

Type: HRESULT

If the function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code. See DirectComposition Error Codes for a list of error codes.

Remarks

A new visual object has a static value of zero for the OffsetX and OffsetY properties, and NULL for the Transform, Clip, and Content properties. Initially, the visual does not cause the contents of a window to change. The visual must be added as a child of another visual, or as the root of a composition target, before it can affect the appearance of a window.

Examples

For an example, see How to Build a Simple Visual Tree.
