Status XQueryBestTile(display, which_screen, width, height,
width_return, height_return)
Display *display;
Drawable which_screen;
unsigned int width, height;
unsigned int *width_return, *height_return;
Status XQueryBestStipple(display, which_screen, width, height,
width_return, height_return)
Display *display;
Drawable which_screen;
unsigned int width, height;
unsigned int *width_return, *height_return;
ARGUMENTS
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.
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 Tile‐
Shape, 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 Tile‐
Shape 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 Bad‐
Match 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 Bad‐
Match error results.
XQueryBestStipple can generate BadDrawable and BadMatch errors.
DIAGNOSTICS
An InputOnly window is used as a Drawable. A value for a Drawable
argument does not name a defined Window or Pixmap. The values do not
exist for an InputOnly window. 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.
