<h4>Customizing the display of the Methods-buffer</h4>
<p>The ECB-Methods buffer is probably the most important browsing window
offered by ECB. It displays all parsing informations of the current
source-buffer (the buffer displayed in the current active
edit-window).
<p>Normally ECB gets all informations displayed in this Methods-buffer
from the semantic-library - at least for semantic-sources. This
library parses auto. the current source-buffer in the edit-window of
ECB and returns all information in form of <dfn>tags</dfn> to ECB which
displays them in a browse-able form in its Method-buffer. See <a href="ECB-Methods-buffer.html#ECB%20Methods-buffer">ECB Methods-buffer</a> for information how to use the Methods-buffer.
<p>There are several options to customize which tags ECB should display
in general, if the tags should be collapsed or expanded, how to
fontify them (i.e. syntax-highlighting) and something more.
<dl>
<dt><code>ecb-show-tags</code>
<dd>With the option <code>ecb-show-tags</code> you specify how ECB should
display the tags returned by the semantic parser. Semantic divides its
tags in several so called <dfn>tag classes</dfn>. A tag-class is always a
symbol and can be for example <code>type</code> (tags which represent a
class<a rel=footnote href="#fn-1"><sup>1</sup></a>, a interface, an enumeration etc.),
<code>function</code> (tags which represent function or methods),
<code>variable</code> (variables and attributes), <code>include</code>
(import-statements) etc. There is no predefined superset of allowed
tag-class-symbols because each language-parser can define its own
tag-classes. But to get an overview of the most common tag-classes see
the default value of the option <code>ecb-show-tags</code>.
<p>With the option <code>ecb-show-tags</code> you can now specify how ECB
should display tags of a certain tag-class in a certain major-mode.
You can tell ECB that all tags of a tag-class <code>X</code> should be
displayed in an expanded bucket and all tags of a tag-class <code>Y</code>
should be displayed in a collapsed bucket and all tags of a tag-class
<code>Z</code> should be displayed flattened (means not contained in a
expandable/collapsable bucket-node). These settings can be made
separately for each major-mode but you can also define a
default-display which takes effect when for a major-mode no special
setting can be found in <code>ecb-show-tags</code>.
<p>For every tag-class you can tell ECB how the tags should be sorted.
<br><dt><code>ecb-font-lock-tags</code>
<dt><code>ecb-type-tag-display</code>
<dd>How to fontify the tags in the Method-buffer
<br><dt><code>ecb-tag-display-function</code>
<dd>ECB and semantic offer several predefined functions for displaying the
tags. Here you can customize, what informations tags should
contain (only the method-name or the whole signature or something
else) and what notation should be used, e.g. UML or not.
</dl>
<p>These are the most important options for this topic but it is
recommended to have a look into the customize-group <code>ecb-methods</code>
(see <a href="ecb-methods.html#ecb-methods">ecb-methods</a>) and check all the options offered there!
<p>All these options are only relevant for semantic-sources and take no
effect for non-semantic-sources!
<hr><h4>Footnotes</h4>
<ol type="1">
<li><a name="fn-1"></a>
<p>Do not confuse the term ``class'' in the context of a
tag, which means the class of the tag and which is a semantic-term and
a ``class'' in the context of an object oriented language like Java or
C++! Normally the surrounding context sould be sufficient to
understand which type of ``class'' is meant whenever the term
``class'' is used in this manual.</p>
