NAME
       wm - window manager

SYNOPSIS
       wm/wm [ command [ arg...	 ] ]

DESCRIPTION
       Wm  is  an  inferno window manager, providing the control mechanism for
       the user to manage to order and position of  a  dynamic	collection  of
       application  windows.   When  started,  it  runs	 command,  (by default
       wm/toolbar, see toolbar(1)) By itself, wm does not  provide  any	 means
       for  starting  new  applications;  that facility must be provided by an
       auxilliary program, wm/toolbar being one such example.

   Control Interface
       Wm provides a control interface to programs running inside  it  through
       the  Wmcontext  adt that can be obtained from the Draw->Context that it
       passes to applications that it starts (see  draw-context(2)).   Control
       messages it understands include:

       start what
	      Start  input  on	what.	What  can be ptr (pointer events), kbd
	      (keyboard events) and control (window  manager  control  events,
	      see below).

       key charval
	      Simulate a key event.  Charval is the decimal value of the char‐
	      acter that has been pressed. The character will be sent  exactly
	      as  if  it had been typed on the keyboard. This facility is used
	      by keyboard(1).

       !reshape tag reqid minx miny maxx maxy [how]
	      Reshape or create the  window  named  tag.   Reqid  is  ignored;
	      minx..maxy  give	the desired bounding rectangle of the new win‐
	      dow.  If how is not given, or is exact, then wm will attempt  to
	      satisfy  the  request  exactly.	Otherwise, how tells wm how to
	      determine the rectangle of the resulting image; it can be one of
	      place  (choose  some  appropriate	 position and size on screen),
	      onscreen (modify the requested rectangle only so as to bring  it
	      on screen), or max (request the maximum available rectangle).

       delete tag
	      Delete the window named by tag.

       raise  Raise all windows for the current context above the others.

       lower  Send all windows for the current context to the bottom.

       !move tag reqid startx starty
	      Drag  window  tag	 interactively.	 Reqid is ignored.  Startx and
	      starty give the location of the pointer when the drag was initi‐
	      ated.

       !size tag reqid
	      Interactively resize window tag.

       fixedorigin
	      By  default,  if	a  window  changes  position  but not size, wm
	      changes the origin of the window without creating a  new	image.
	      Sending  fixedorigin  caused  wm always to create a new image in
	      that case.

       kbdfocus [in]
	      If the decimal integer in	 is  non-zero,	request	 the  keyboard
	      focus, otherwise lose the keyboard focus.

       Wm  generates  control  messages	 to inform applications of things that
       have happened. These include:

       rect minx miny maxx maxy
	      The screen rectangle has	changed.   minx..maxy  gives  the  new
	      bounding box of the screen.

       haskbdfocus in
	      Informs  an  application	of  its	 current keyboard focus state.
	      This message is generated in response to pointer events, and due
	      to kbdfocus requests.

       exit   The window manager is closing down.

   Controlling Application
       The  first  application	that starts under wm is given the privilege of
       being able to control other applications running under the same wm.  If
       it  sends  a  start  control message, then it will also see any control
       requests sent by applications that wm itself does  not  understand  and
       information  about  applications starting and leaving.  Wm accepts sev‐
       eral other control messages from its controlling application:

       ctl id msg
	      Send message msg to application id.

       endcontrol
	      Relinquish controller status.  The next application that	starts
	      will  get	 control status.  This is used, for instance, to segue
	      smoothly between logon(1) and toolbar(1).

       If the controlling application has started control messages,  wm	 sends
       it the following messages:

       newclient id
	      A new client has connected, identified by id.

       delclient id
	      Client id has left.

       request id msg
	      Client  id  sent the request msg to the window manager, which it
	      did not understand.  This facility is  used,  for	 instance,  by
	      toolbar(1) to implement the task and untask requests.

FILES
       /chan/wmrect
	      File holding current screen rectangle.
