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.
