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.
