.TH WM 1 .SH NAME wm \- window manager .SH SYNOPSIS .B wm/wm [ .I command [ .IR arg ... ] ] .SH DESCRIPTION .I 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 .IR command , (by default .BR wm/toolbar , see .IR toolbar (1)) By itself, .I wm does not provide any means for starting new applications; that facility must be provided by an auxilliary program, .B wm/toolbar being one such example. .SS Control Interface .I Wm provides a control interface to programs running inside it through the .B Wmcontext adt that can be obtained from the .B Draw->Context that it passes to applications that it starts (see .IR draw-context (2)). Control messages it understands include: .TP .B start \fIwhat\fP Start input on .IR what . .I What can be .BR ptr (pointer events), .BR kbd (keyboard events) and .BR control (window manager control events, see below). .TP .B key \fIcharval\fP Simulate a key event. .I Charval is the decimal value of the character that has been pressed. The character will be sent exactly as if it had been typed on the keyboard. This facility is used by .IR keyboard (1). .TP .B !reshape \fItag\fP \fIreqid\fP \fIminx miny maxx maxy\fI \fR[\fIhow\fR] Reshape or create the window named .IR tag . .I Reqid is ignored; .I minx..maxy give the desired bounding rectangle of the new window. If .I how is not given, or is .BR exact , then .I wm will attempt to satisfy the request exactly. Otherwise, .I how tells .I wm how to determine the rectangle of the resulting image; it can be one of .B place (choose some appropriate position and size on screen), .B onscreen (modify the requested rectangle only so as to bring it on screen), or .B max (request the maximum available rectangle). .TP .B delete \fItag\fP Delete the window named by \fItag\fP. .TP .B raise Raise all windows for the current context above the others. .TP .B lower Send all windows for the current context to the bottom. .TP .B !move \fItag\fP \fIreqid\fP \fIstartx\fP \fIstarty\fP Drag window .I tag interactively. .I Reqid is ignored. .I Startx and .I starty give the location of the pointer when the drag was initiated. .TP .B !size \fItag\fP \fIreqid\fP Interactively resize window \fItag\fP. .TP .B fixedorigin By default, if a window changes position but not size, .I wm changes the origin of the window without creating a new image. Sending .B fixedorigin caused .I wm always to create a new image in that case. .TP .B kbdfocus \fR[\fIin\fR] If the decimal integer .I in is non-zero, request the keyboard focus, otherwise lose the keyboard focus. .PP .I Wm generates control messages to inform applications of things that have happened. These include: .TP .B rect \fIminx miny maxx maxy\fP The screen rectangle has changed. .I "minx..maxy" gives the new bounding box of the screen. .TP .B haskbdfocus \fIin\fP Informs an application of its current keyboard focus state. This message is generated in response to pointer events, and due to .B kbdfocus requests. .TP .B exit The window manager is closing down. .SS Controlling Application The first application that starts under .I wm is given the privilege of being able to control other applications running under the same .IR wm . If it sends a .B start control message, then it will also see any control requests sent by applications that .I wm itself does not understand and information about applications starting and leaving. .I Wm accepts several other control messages from its controlling application: .TP .B ctl \fIid\fP \fImsg\fP Send message .I msg to application .IR id . .TP .B endcontrol Relinquish controller status. The next application that starts will get control status. This is used, for instance, to segue smoothly between .IR logon (1) and .IR toolbar (1). .PP If the controlling application has started control messages, .I wm sends it the following messages: .TP .B newclient \fIid\fP A new client has connected, identified by .IR id . .TP .B delclient \fIid\fP Client .I id has left. .TP .B request \fIid\fP \fImsg\fP Client .I id sent the request .I msg to the window manager, which it did not understand. This facility is used, for instance, by .IR toolbar (1) to implement the .B task and .B untask requests. .SH FILES .TP .B /chan/wmrect File holding current screen rectangle. .SH SOURCE .B /appl/wm/wm.b .SH "SEE ALSO" .IR toolbar (1), .IR logon (1), .IR tkclient (2), .IR wmclient (2)
