NAME
XQueryBestSize, XQueryBestTile, XQueryBestStipple - deter-
mine 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 Stip-
pleShape.
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 draw-
able for TileShape or StippleShape, or a BadMatch error
results.

XQueryBestSize can generate BadDrawable, BadMatch, and Bad-
Value 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 Inpu-
tOnly 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 Inpu-
tOnly 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 gen-
erate this error.
