<h4>How to refresh ECB-state-display when changed outside</h4>
<p>If all actions concerning version controlling of a file are performed
within Emacs with commands offeres by VC then the displayed state for
such a file in the tree-buffers of ECB will be always correct - in
that sense that ECB will always display that state which the
check-state-function for the file will return. At least with GNU Emacs
for the backends CVS, RCS, SCCS and Subversion this will be true. With
XEmacs only for CVS. For other backends see <a href="Adding-new-backends.html#Adding%20new%20backends">Adding new backends</a>.
<p>But if the VC-state of a file will be changed outside of Emacs
(unfortunately PCL-CVS must be called "outside" too because PCL-CVS
doesn't use the functions of the VC-package of Emacs for checking-in
or -out) then ECB can not automatically recognize this and therefore
it can not aurtomatically update the displayed state-image-icon. You
have to tell ECB for which files in the tree-buffers the VC-state
should be recomputed. This can be done via the popup-menus of the
ECB-tree-buffers - The following popup-commands are offered in the
submenu "Version Control":
<dl>
<dt>ECB-directories-buffer (if sources are displayed within):
<dd>"Recompute state for file" and "Recompute state for dir" whereas
the latter one recomputes the VC-state for all files of that directory
the file belongs.
<br><dt>ECB-sources-buffer
<dd>"Recompute state for file" and "Recompute state for dir" whereas
the latter one recomputes the VC-state for all files currently
displayed in the sources-buffer.
<br><dt>ECB-history-buffer
<dd>"Recompute state for file" and "Recompute state for whole history"
whereas the latter one recomputes the VC-state for all file-entries currently
displayed in the history-buffer.
</dl>
<p><strong>Caution</strong>: The state will only recomputed right under all
situations if you use either <code>ecb-vc-state</code> or
<code>vc-recompute-state</code> as check-state-function in
<code>ecb-vc-supported-backends</code> (see <a href="Checking-the-state.html#Checking%20the%20state">Checking the state</a>).
<p>Of course all these commands update the VC-state in all visible
tree-buffers the file is currently displayed (e.g. often a file is
displayed in the sources- and the history-buffer)!
<p>For general informations about the usage of popup-menus in ECB see
<a href="Using-the-mouse.html#Using%20the%20mouse">Using the mouse</a> (subsection "The right mouse button").
<p>In addition to these popup-commands using the POWER- rsp. Shift-click
(see <a href="Using-the-mouse.html#Using%20the%20mouse">Using the mouse</a>) onto a directory in the directory-window of
ECB refreshes the VC-state-values of all files contained in this
directory too.
