NAME

       XQueryBestSize, XQueryBestTile, XQueryBestStipple - determine efficient
       sizes


SYNTAX

       Status   XQueryBestSize(Display   *display,   int    class,    Drawable
              which_screen,  unsigned int width, unsigned int height, unsigned
              int *width_return, unsigned int *height_return);

       Status XQueryBestTile(Display *display, Drawable which_screen, unsigned
              int  width,  unsigned  int  height,  unsigned int *width_return,
              unsigned int *height_return);

       Status  XQueryBestStipple(Display  *display,   Drawable   which_screen,
              unsigned   int   width,   unsigned   int  height,  unsigned  int
              *width_return, unsigned int *height_return);


ARGUMENTS

       class     Specifies the class that you are interested in.  You can pass
                 TileShape, CursorShape, or StippleShape.

       display   Specifies the connection to the X server.

       width
       height    Specify the width and height.

       which_screen
                 Specifies any drawable on the screen.

       width_return
       height_return
                 Return  the  width and height of the object best supported by
                 the display hardware.


DESCRIPTION

       The XQueryBestSize function returns the best or  closest  size  to  the
       specified  size.  For CursorShape, this is the largest size that can be
       fully displayed on the screen specified  by  which_screen.   For  Tile-
       Shape,  this  is the size that can be tiled fastest.  For StippleShape,
       this is the size that can be stippled fastest.   For  CursorShape,  the
       drawable indicates the desired screen.  For TileShape and StippleShape,
       the drawable indicates the screen and possibly  the  window  class  and
       depth.   An  InputOnly  window cannot be used as the drawable for Tile-
       Shape or StippleShape, or a BadMatch error results.

       XQueryBestSize can generate BadDrawable, BadMatch, and BadValue errors.

       The  XQueryBestTile function returns the best or closest size, that is,
       the size  that  can  be  tiled  fastest  on  the  screen  specified  by
       which_screen.   The drawable indicates the screen and possibly the win-
       dow class and depth.  If an InputOnly window is used as the drawable, a
       BadMatch error results.

       XQueryBestTile can generate BadDrawable and BadMatch errors.

       The  XQueryBestStipple  function returns the best or closest size, that
       is, the size that can be stippled fastest on the  screen  specified  by
       which_screen.   The drawable indicates the screen and possibly the win-
       dow class and depth.  If an InputOnly window is used as the drawable, a
       BadMatch error results.

       XQueryBestStipple can generate BadDrawable and BadMatch errors.


DIAGNOSTICS

       BadMatch  An InputOnly window is used as a Drawable.

       BadDrawable
                 A  value for a Drawable argument does not name a defined Win-
                 dow or Pixmap.

       BadMatch  The values do not exist for an InputOnly window.

       BadValue  Some numeric value falls outside the range of values accepted
                 by  the request.  Unless a specific range is specified for an
                 argument, the full range defined by the  argument's  type  is
                 accepted.   Any argument defined as a set of alternatives can
                 generate this error.
