IViewObjectPresentFlipSite::GetMetrics method

  • Article

Returns the position and size of the ActiveX control (in pixels), and the current scale factor that Internet Explorer is applying to the control.

Syntax

HRESULT GetMetrics(
  [out] POINT* *pPos,
  [out] SIZE*  *pSize,
  [out] float* *pScaleX,
  [out] float* *pScaleY
);

Parameters

  • pPos [out]
    The position of the control in pixels, relative to the mshtml window.

  • pSize [out]
    The size of the control that should be created, in pixels. This might be different to the displayed size while manipulations happen.

  • pScaleX [out]
    The X dimension scale factor for the control. For example, if you pinch zoom the page to 200%, then a control will have (2.0f, 2.0f) for the scale factors. A control can use this to appropriately scale UI inside of itself to match the rest of the zooming on the page.

  • pScaleY [out]
    The Y dimension scale factor for the control.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

The size can then be passed to CreateSurfacePresenterFlip.

The values returned are only valid if called during NotifyRender.
