WMLIB(2) WMLIB(2)
NAME
wmlib - low level access to window manager
SYNOPSIS
include "sys.m";
include "draw.m";
include "wmlib.m";
wmlib := load Wmlib Wmlib->PATH;
init: fn();
connect: fn(ctxt: ref Draw->Context): ref Draw->Wmcontext;
startinput: fn(w: ref Draw->Wmcontext, devs: list of string): string;
wmctl: fn(w: ref Draw->Wmcontext, request: string): (string, ref Draw->Image, string);
snarfput: fn(buf: string);
snarfget: fn(): string;
DESCRIPTION
Wmlib provides basic routines to access the window manager,
It is used by higher level modules such as tkclient(2) and
wmclient(2) to provide window manager access to applica-
tions.
Init should be called once to initialise the internal state
of Wmlib. Connect makes a connection to the window manager
through ctxt (see draw-context(2)). Startinput tells the
window manager to start queuing events on the input streams
named in devs (e.g. ptr, kbd) so that they can be received
by the application.
Wmctl sends request to the window manager. It returns a
tuple, say (name, img, err). If a request fails, then name
and img will be nil and the non-empty err gives the reason.
If the request has resized or created an image, name gives
the tag name of the image and img holds the new image.
Wmlib interprets the exit request itself, by killing all
processes in the current process group, and exiting.
Snarfget and snarfput retrieve and replace the contents of
the window manager's snarf buffer.
