Methods
The IHTMLPainterOverlay interface has these methods.
| Method | Description |
|---|---|
| OnMove | Called by MSHTML when the element to which a rendering behavior is attached is repositioned or resized on the screen. |
Remarks
Note Currently, this interface is not fully supported.
MSHTML calls the method of this inferface so that a rendering behavior can use the DirectDraw hardware overlay buffer for drawing, if the buffer is present.
To enable this feature, a rendering behavior must set the HTMLPAINTER_OVERLAY HTMLPAINTER_OVERLAY bit in the HTML_PAINTER structure that it passes to MSHTML in its implementation of IHTMLPainter::GetPainterInfo.
When the HTMLPAINTER_OVERLAY bit is set and a rendering behavior is instantiated on a page, MSHTML automatically calls QueryInterface on the behavior's IHTMLPainter interface and requests an IHTMLPainterOverlay interface pointer to determine if one is present. If it is, MSHTML calls the IHTMLPainterOverlay::OnMove method whenever the element to which a rendering behavior is attached is repositioned or resized on the screen.
