NAME
XQueryBestSize, XQueryBestTile, XQueryBestStipple - determine 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 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.
