-.SH DESCRIPTION
-.PP
-\fBTk_MaintainGeometry\fR and \fBTk_UnmaintainGeometry\fR make it
-easier for geometry managers to deal with slaves whose masters are not
-their parents.
-Three problems arise if the master for a slave is not its parent:
-.IP [1]
-The x- and y-position of the slave must be translated from the
-coordinate system of the master to that of the parent before
-positioning the slave.
-.IP [2]
-If the master window, or any of its ancestors up to the slave's
-parent, is moved, then the slave must be repositioned within its
-parent in order to maintain the correct position relative to the
-master.
-.IP [3]
-If the master or one of its ancestors is mapped or unmapped, then
-the slave must be mapped or unmapped to correspond.
-.LP
-None of these problems is an issue if the parent and master are
-the same. For example, if the master or one of its ancestors
-is unmapped, the slave is automatically removed by the screen
-by X.
-.PP
-\fBTk_MaintainGeometry\fR deals with these problems for slaves
-whose masters are not their parents, as well as handling the simpler
-case of slaves whose masters are their parents.
-\fBTk_MaintainGeometry\fR is typically called by a window manager
-once it has decided where a slave should be positioned relative
-to its master.
-\fBTk_MaintainGeometry\fR translates the coordinates to the
-coordinate system of \fIslave\fR's parent and then moves and
-resizes the slave appropriately.
-Furthermore, it remembers the desired position and creates event
-handlers to monitor the master and all of its ancestors up
-to (but not including) the slave's parent.
-If any of these windows is moved, mapped, or unmapped,
-the slave will be adjusted so that it is mapped only when the
-master is mapped and its geometry relative to the master
-remains as specified by \fIx\fR, \fIy\fR, \fIwidth\fR, and
-\fIheight\fR.
-.PP
-When a window manager relinquishes control over a window, or
-if it decides that it does not want the window to appear on the
-screen under any conditions, it calls \fBTk_UnmaintainGeometry\fR.
-\fBTk_UnmaintainGeometry\fR unmaps the window and cancels any
-previous calls to \fBTk_MaintainGeometry\fR for the
-\fImaster\fR\-\fIslave\fR pair, so that the slave's
-geometry and mapped state are no longer maintained
-automatically.
-\fBTk_UnmaintainGeometry\fR need not be called by a geometry
-manager if the slave, the master, or any of the master's ancestors
-is destroyed: Tk will call it automatically.
-.PP
-If \fBTk_MaintainGeometry\fR is called repeatedly for the same
-\fImaster\fR\-\fIslave\fR pair, the information from the most
-recent call supersedes any older information.
-If \fBTk_UnmaintainGeometry\fR is called for a \fImaster\fR\-\fIslave\fR
-pair that is is not currently managed, the call has no effect.
