Retrieves the height of the ribbon.

Syntax

HRESULT GetHeight(
  [out] UINT32 *cy
);

Parameters

[out] cy

Type: UINT32*

The height of the ribbon, in pixels.

Return value

Type: HRESULT

Examples

The following example demonstrates how to use the IUIRibbon::GetHeight method to retrieve the height of the ribbon to calculate a display location for a Context Popup control.

void GetDisplayLocation(POINT &pt, HWND hWnd)
{
  if (pt.x == -1 && pt.y == -1)
  {
    HRESULT hr = E_FAIL;

    // Display the menu in the upper-left corner of the client area, below the ribbon.
    IUIRibbon* pRibbon;
    hr = g_pFramework->GetView(0, IID_PPV_ARGS(&pRibbon));
    if (SUCCEEDED(hr))
    {
      UINT32 uRibbonHeight = 0;
      hr = pRibbon->GetHeight(&uRibbonHeight);
      if (SUCCEEDED(hr))
      {
        pt.x = 0;
        pt.y = uRibbonHeight;
        // Convert client coordinates of a specified point to screen coordinates.
        ClientToScreen(hWnd, &pt);
      }
      pRibbon->Release();
    }
    if (FAILED(hr))
    {
      // Default to just the upper-right corner of the entire screen.
      pt.x = 0;
      pt.y = 0;
    }
  }
}
