XQueryBestSize(3)               XLIB FUNCTIONS               XQueryBestSize(3)


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.
