ARGUMENTS

class     Specifies the class that you are interested in.
          You can pass TileShape, CursorShape, or Stip-
          pleShape.

display   Specifies the connection to the XWIN 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 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
InputOnly window is used as the drawable, a BadMatch error
results.

XQueryBestTile can generate BadDrawable and BadMatch errors.

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 gen-
          erate this error.
