      if \c fontSize is less than 0 it is interpreted as being a per-mille value
      of the size of the drawing area (or of the height of the box in case
      \c fontScaleGlobal is set to false, resp.).
      Normally the actual font size is calculated dynamically in methode paint.
      <b>However</b> if fontSize is zero no calculating will take place but the
      size of the content font is used.
      \param fontScaleGlobal If true the font size will be calculated based
      upon the the size of the drawing area, otherwise it will be calculated
      based upon the height of the box.
      \param deltaX The X distance between the box and its anchor.
      <b>Note: </b> If greater 0, the value is taken as exact offset,
      if less than 0, it is interpreted as being a per-mille value of the
      size of the drawing area (or as percent value of the actual font size
      (as returned by TQFontMetrics::lineSpacing() ) if deltaScaleGlobal is FALSE, resp.).
      Actual drawing position/size is calculated dynamically in methode trueRect.
      \param deltaY The Y distance between the box and its anchor.
      \param width The width of the box.
      \param height The height of the box.
      \param color The text color.
      \param paper The brush to be used for the background.
      \param area The area to which the box is to be aligned.
      \param position The anchor position. This is the edge (or
      the corner, resp.) of the area to which
      the box is to be aligned.
      \param align The way how the box is to be aligned to its anchor.
      \param dataRow The row number of the KDChart data region that is to be used
      as anchor area. This parameter is ignored if \c area is not \c AreaChartDataRegion.
      \param dataCol The column number of the KDChart data region that is to be used
      as anchor area. This parameter is ignored if \c area is not \c AreaChartDataRegion.
      \param data3rd The third dimensions number of the KDChart data region that is to be used
      as anchor area. This parameter is ignored if \c area is not \c AreaChartDataRegion
      or if there is no 3-dimensional data structure.
      \param deltaAlign The way how \c deltaX and \deltaY affect the position of the box.
      Leave this parameter to its default value KDCHART_AlignAuto to have the delta values
      used according to the box's main \c align settings, otherwise specify your own
      alignment settings: e.g. right means there will be a gap between the right side of
      the box and its anchor point - if the main \c align parameter is set to right too
      the anchor point will to be outside of the box / if \c align is set to left
      (but the \c deltaAlign to right) the anchor point will be inside the box.
      Possible values for \c deltaAlign are:
      \li \c KDCHART_AlignAuto
      \li \c TQt::AlignLeft | TQt::AlignTop
      \li \c TQt::AlignLeft | TQt::AlignBottom
      \li \c TQt::AlignRight | TQt::AlignTop
      \li \c TQt::AlignRight | TQt::AlignBottom
      Using AlignVCenter or AlignHCenter or AlignCenter does not make sense here:
      center delta alignment will cause KDChart to ignore the respective delta
      settings: deltaX or deltaY or both will become ineffective.
      \param deltaScaleGlobal If true the actual delta X and delta Y values will
      be calculated by \c deltaX and \c deltaY based upon the size of the
      drawing area, otherwise they will be calculated based upon the actual
      font size.

      and \c fontScaleGlobal is true the size of the box will be calculated
      automatically based upon the content size.  In this case the content
      size is interpreted as rich text string - even if the text is NOT
      framed by <tt><qt></tt> and <tt></qt></tt>.

      \param rotation The box's rotation angle in degrees (0 .. 360).
      \param content The text piece to be displayed.
      \param fontSize If \c fontSize value is greater 0, the value is taken as exact size,
      if \c fontSize is less than 0 it is interpreted as being a per-mille value
      of the size of the drawing area (or of the height of the box in case

      Normally the actual font size is calculated dynamically in methode paint.
      <b>However</b> if fontSize is zero no calculating will take place but the
      size of the content font is used.
      \param fontScaleGlobal If true the font size will be calculated based
      upon the the size of the drawing area, otherwise it will be calculated
      based upon the height of the box.
      \param deltaX The X distance between the box and its anchor.
      <b>Note: </b> If greater 0, the value is taken as exact offset,
      if less than 0, it is interpreted as being a per-mille value of the
      width of the drawing area (or as percent value of the actual font size
      (as returned by TQFontMetrics::lineSpacing() ) if deltaScaleGlobal is FALSE, resp.).
      Actual drawing position/size is calculated dynamically in method trueRect.

      \param area The area to which the box is to be aligned.
      \param position The anchor position. This is the edge (or
      the corner, resp.) of the area to which the box is to be aligned
      and it is also used as the reference point of the rotation.
      \param align The way how the box is to be aligned to its anchor.
      \param dataRow The row number of the KDChart data region that is to be used
      as anchor area. This parameter is ignored if \c area is not \c AreaChartDataRegion.

      Leave this parameter to its default value KDCHART_AlignAuto to have the delta values
      used according to the box's main \c align settings, otherwise specify your own
      alignment settings: e.g. TQt::AlignRight means the box will be moved to the left
      (by the amount calculated using the \c deltaX value), so there will be a gap
      between the right side of the box and its anchor point IF the main \c align flag
      is set to TQt::AlignRight too, so the anchor point will to be outside of the
      box then. However if the main \c align flag is set to TQt::AlignLeft the anchor
      point will be inside the box.
      Possible values for \c deltaAlign are:

      Using AlignVCenter or AlignHCenter or AlignCenter does not make sense here:
      center delta alignment will cause KDChart to ignore the respective delta
      settings: deltaX or deltaY or both will become ineffective.
      \note Moving of the box due to \c deltaAlign settings is applied after
      the box is rotated: e.g. this means a gap specified by \c deltaAlign = TQt::AlignTop
      gap will actually result in a left gap if the box is rotated by 90 degrees.
      \param deltaScaleGlobal If true the actual delta X and delta Y values will
      be calculated by \c deltaX and \c deltaY based upon the size of the
      drawing area, otherwise they will be calculated based upon the actual
      font size.

      Set this to KDHART_KDCHART_AlignAuto to have the delta values
      used according to the box's main \c align settings, otherwise specify your own
      alignment settings: e.g. right means there will be a gap between the right side of
      the box and its anchor point - if the main \c align parameter is set to right too
      the anchor point will to be outside of the box / if \c align is set to left
      (but the \c deltaAlign to right) the anchor point will be inside the box.
      Possible values for \c deltaAlign are:
      \li \c KDCHART_AlignAuto
      \li \c TQt::AlignLeft | TQt::AlignTop
      \li \c TQt::AlignLeft | TQt::AlignBottom
      \li \c TQt::AlignRight | TQt::AlignTop
      \li \c TQt::AlignRight | TQt::AlignBottom
      Using AlignVCenter or AlignHCenter or AlignCenter does not make sense here:
      center delta alignment will cause KDChart to ignore the respective delta
      settings: deltaX or deltaY or both will become ineffective.
      \note Moving of the box due to \c deltaAlign settings is applied after
      the box is rotated: e.g. this means a gap specified by \c deltaAlign = TQt::AlignTop
      gap will actually result in a left gap if the box is rotated by 90 degrees.
