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  TileShape,  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 TileShape 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  window 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 window 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 Window 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.
