xquerybestsize(3x)
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.
