Please implement the CExtTabWnd::OnTabWndGetParentSizingMargin() virtual method like as follows:

virtual INT OnTabWndGetParentSizingMargin( DWORD dwOrientation ) const
{
      ASSERT_VALID( this );
INT nRetVal = __parent_tab_class_name_here__ :: OnTabWndGetParentSizingMargin( dwOrientation );
      switch( dwOrientation )
      {
      case __ETWS_ORIENT_TOP:
      {
            INT nPixelCountToIncreaseHeightOfTopDockedTabWindow = . . .
            nRetVal += nPixelCountToIncreaseTopDockedTabWindow;
      }
      break;
      case __ETWS_ORIENT_BOTTOM:
      {
            INT nPixelCountToIncreaseHeightOfBottomDockedTabWindow = . . .
            nRetVal += nPixelCountToIncreaseHeightOfBottomDockedTabWindow;
      }
      break;
      case __ETWS_ORIENT_LEFT:
      {
            INT nPixelCountToIncreaseWidthOfLeftDockedTabWindow = . . .
            nRetVal += nPixelCountToIncreaseTopDockedTabWindow;
      }
      break;
      case __ETWS_ORIENT_RIGHT:
      {
            INT nPixelCountToIncreaseWidthOfRightDockedTabWindow = . . .
            nRetVal += nPixelCountToIncreaseTopDockedTabWindow;
      }
      break;
#if (defined _DEBUG)
      default:
            ASSERT( FALSE );
      return 0;
#endif // _DEBUG
      } // switch( dwOrientation )
      return nRetVal;
}

You should override the following virtual method of the CExtTabWnd class:

      virtual void OnTabWndUpdateItemMeasure(
            TAB_ITEM_INFO * pTii,
            CDC & dcMeasure,
            CSize & sizePreCalc
            );
The sizePreCalc parameter contains the size of the pTii tab item measured by default . You should just make it wider and higher.

Hello.


Will such an expression be possible, too?



Thanks,
