<h1>
<a name="dlg_dependencies.htm"></a>Dependencies Dialogue Box
</h1>
<p>
This dialogue box contains two tabs. The first, labelled <em>Depends
Upon</em> displays all the other snippets that the selected snippet
depends upon (i.e. requires in order to compile). The <em>Required By</em>
tab displays all the snippets that directly require, or depend upon, the
selected snippet.
</p>
<p>
Which tabs are displayed depends on how the dialogue box is accessed:
</p>
<ol>
<li>
Choosing the <em>View | Dependencies</em> menu item when it displays
both tabs of the dialogue box with information about the dependencies
for the currently selected snippet.
</li>
<li>
Clicking the <em>View Dependencies</em> button on the
<em>References</em> tab in the
<a href="dlg_editsnippet.htm">Snippets Editor</a> displays just the
<em>Depends Upon</em> tab.
</li>
</ol>
<h2>
<em>Depends Upon</em> Tab
</h2>
<p>
If the selected snippet has dependenciess a tree of snippets is displayed
that shows the direct and indirect dependencies. When there are no
dependencies a message is displayed to that effect.
</p>
<p>
If a circular reference is detected (i.e. the snippet depends directly or
indirectly upon itself) the circular reference is displayed in red and an
error message is displayed. Circular references are not permitted and must
be corrected. This should only occur when the dialogue box is displayed
from the <a href="dlg_editsnippet.htm">Snippets Editor</a>.
</p>
<h2>
<em>Required By</em> Tab
</h2>
<p>
This tab displays a simple list of snippets that immediately depend on the
selected snippet. Again, if there are no snippets to list a message is
displayed to that effect.
