<h3>Source View</h3>
<p>The source view is the most sophisticated part of JSwat. It uses
a Java language parser to colorize the lexical elements of the
file, identify the locations and names of the defined classes, and
determine the locations of all of the methods. It uses a popup menu
to manage breakpoints and scroll to method definitions.</p>
<a name="gutter"></a>
<h4>The Gutter</h4>
<p>The gutter is the place where the line numbers are shown, on the
left side of the source view. The background color is used to
indicate the location of breakpoints. The default light gray
indicates that line does not have a breakpoint. The other colors
are defined as follows:</p>
<dl>
<dt><strong>Red</strong></dt>
<dd>Expired; hit count reached 'expire count'.</dd>
<dt><strong>Gray</strong></dt>
<dd>Disabled by user.</dd>
<dt><strong>Blue</strong></dt>
<dd>Unresolved; waiting for class to load.</dd>
<dt><strong>Yellow</strong></dt>
<dd>Skipping hits until 'skip count' is reached.</dd>
<dt><strong>Green</strong></dt>
<dd>Ready to be hit.</dd>
</dl>
<h4>Current Location</h4>
<p>The current location is like the current thread (see <a href=
"threads.html">Threads, Call Stack</a>). It is set whenever a
breakpoint is hit and indicates the line about to be executed in
the debuggee. The line is indicated in the source view using a blue
highlight across that line. Changing the current thread or stack
frame will move the highlight to the corresponding line of the
appropriate source view.</p>
<h4>Searching</h4>
<p>You can search for words and phrases in the source view by using
the "Search Source" menu item in the "View"
menu (or the toolbar button with the binoculars). In the Find
dialog, simply enter the word or phrase you are looking for, then
click Ok. To ignore letter casing, select the checkbox
provided.</p>
<h4>Options</h4>
<p>There are a number of options affecting the view, which include
the following. They are specified in the "View" category
of the user preferences dialog.</p>
<dl>
<dt><strong>Colorize</strong></dt>
<dd>This enables or disables the use of a Java lexical analyzer
to determine the locations of all of the tokens in the source
file. This information, when enabled, is used to colorize the
source code. You may want to disable this if you usually view
files that are not Java source code.</dd>
<dt><strong>Parse as Java</strong></dt>
<dd>This enables or disables the use of a Java language parser to
determine the locations of all of the classes and methods in the
source file. This information, when enabled, is used to set
breakpoints and scroll to method definitions. You may want to
disable this if you usually view files that are not Java source
code.</dd>
<dt><strong>Maximize</strong></dt>
<dd>When enabled, the source view windows will be maximized when
they are first opened.</dd>
