<p>This tool helps with finding Qt4 tools and libraries,
and also provides syntactic sugar for using Qt4 tools.</p>
<p>The following snippet illustrates the tool usage:</p>

<h2>Usage<a class="headerlink" href="#usage" title="Permalink to this headline">¶</a></h2>
<p>Load the “qt4” tool.</p>
<p>You also need to edit your sources accordingly:</p>
<ul>
<li><p class="first">the normal way of doing things is to have your C++ files
include the .moc file.
This is regarded as the best practice (and provides much faster
compilations).
It also implies that the include paths have beenset properly.</p>
</li>
<li><p class="first">to have the include paths added automatically, use the following:</p>

<p>Note: another tool provides Qt processing that does not require
.moc includes, see ‘playground/slow_qt/’.</p>
<p>A few options (–qt{dir,bin,...}) and environment variables
(QT4_{ROOT,DIR,MOC,UIC,XCOMPILE}) allow finer tuning of the tool,
tool path selection, etc; please read the source for more info.</p>

<p>SAX parsers are strongly encouraged (though not absolutely

the locator to the application by invoking this method before
invoking any of the other methods in the DocumentHandler
interface.</p>
<p>The locator allows the application to determine the end
position of any document-related event, even if the parser is
not reporting an error. Typically, the application will use
this information for reporting its own errors (such as
character content that does not match an application’s
business rules). The information returned by the locator is
probably not sufficient for use with a search engine.</p>
<p>Note that the locator will return correct information only
during the invocation of the events in this interface. The
application should not attempt to use it at any other time.</p>

may skip external entities, depending on the values of the

default).</p>
<p>There are cases, however, when applications need to use
prefixes in character data or in attribute values, where they
cannot safely be expanded automatically; the
start/endPrefixMapping event supplies the information to the
application to expand prefixes in those contexts itself, if
necessary.</p>
<p>Note that start/endPrefixMapping events are not guaranteed to
be properly nested relative to each-other: all
startPrefixMapping events will occur before the corresponding
startElement event, and all endPrefixMapping events will occur
after the corresponding endElement event, but their order is
not guaranteed.</p>
