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.
