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.
