Specifies the class that you are interested
in. You can pass TileShape, CursorShape, or StippleShape.
Specifies
the connection to the X server.
Specify the width and height.
Specifies any drawable on the screen.
Return the width and height of the object best supported by the display
hardware.
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.
- 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.
