|
|
The
|
|
.ZN XMapWindow
|
|
function
|
|
maps the window and all of its
|
|
subwindows that have had map requests.
|
|
Mapping a window that has an unmapped ancestor does not display the
|
|
window but marks it as eligible for display when the ancestor becomes
|
|
mapped.
|
|
Such a window is called unviewable.
|
|
When all its ancestors are mapped,
|
|
the window becomes viewable
|
|
and will be visible on the screen if it is not obscured by another window.
|
|
This function has no effect if the window is already mapped.
|
|
.LP
|
|
If the override-redirect of the window is
|
|
.ZN False
|
|
and if some other client has selected
|
|
.ZN SubstructureRedirectMask
|
|
on the parent window, then the X server generates a
|
|
.ZN MapRequest
|
|
event, and the
|
|
.ZN XMapWindow
|
|
function does not map the window.
|
|
Otherwise, the window is mapped, and the X server generates a
|
|
.ZN MapNotify
|
|
event.
|
|
.LP
|
|
If the window becomes viewable and no earlier contents for it are remembered,
|
|
the X server tiles the window with its background.
|
|
If the window's background is undefined,
|
|
the existing screen contents are not
|
|
altered, and the X server generates zero or more
|
|
.ZN Expose
|
|
events.
|
|
If backing-store was maintained while the window was unmapped, no
|
|
.ZN Expose
|
|
events
|
|
are generated.
|
|
If backing-store will now be maintained,
|
|
a full-window exposure is always generated.
|
|
Otherwise, only visible regions may be reported.
|
|
Similar tiling and exposure take place for any newly viewable inferiors.
|
|
.LP
|
|
.IN "XMapWindow"
|
|
If the window is an
|
|
.ZN InputOutput
|
|
window,
|
|
.ZN XMapWindow
|
|
generates
|
|
.ZN Expose
|
|
events on each
|
|
.ZN InputOutput
|
|
window that it causes to be displayed.
|
|
If the client maps and paints the window
|
|
and if the client begins processing events,
|
|
the window is painted twice.
|
|
To avoid this,
|
|
first ask for
|
|
.ZN Expose
|
|
events and then map the window,
|
|
so the client processes input events as usual.
|
|
The event list will include
|
|
.ZN Expose
|
|
for each
|
|
window that has appeared on the screen.
|
|
The client's normal response to
|
|
an
|
|
.ZN Expose
|
|
event should be to repaint the window.
|
|
This method usually leads to simpler programs and to proper interaction
|
|
with window managers.
|
|
.LP
|
|
.ZN XMapWindow
|
|
can generate a
|
|
.ZN BadWindow
|
|
error.

|

|
.\" $Header: XMapRaised.d,v 1.2 88/05/07 12:22:21 mento Exp $
|
|
The
|
|
.ZN XMapRaised
|
|
function
|
|
essentially is similar to
|
|
.ZN XMapWindow
|
|
in that it maps the window and all of its
|
|
subwindows that have had map requests.
|
|
However, it also raises the specified window to the top of the stack.
|
|
.LP
|
|
.ZN XMapRaised
|
|
can generate a
|
|
.ZN BadWindow
|
|
error.
|
|
.LP
|
|
.\" $Header: XMapSubs.d,v 1.3 88/06/11 07:51:57 mento Exp $
|
|
The
|
|
.ZN XMapSubwindows
|
|
.IN "XMapSubwindows"
|
|
function maps all subwindows for a specified window in top-to-bottom stacking
|
|
order.
|
|
The X server generates
|
|
.ZN Expose
|
|
events on each newly displayed window.
|
|
This may be much more efficient than mapping many windows
|
|
one at a time because the server needs to perform much of the work
|
|
only once, for all of the windows, rather than for each window.
