<h2>Detailed Description</h2>
<p>The QMetaEnum class provides meta-data about an enumerator.</p>
<p>Use <a href="qmetaenum.html#name">name</a>() for the enumerator's name. The enumerator's keys (names of each enumerated item) are returned by <a href="qmetaenum.html#key">key</a>(); use <a href="qmetaenum.html#keyCount">keyCount</a>() to find the number of keys. <a href="qmetaenum.html#isFlag">isFlag</a>() returns whether the enumerator is meant to be used as a flag, meaning that its values can be combined using the OR operator.</p>
<p>The conversion functions <a href="qmetaenum.html#keyToValue">keyToValue</a>(), <a href="qmetaenum.html#valueToKey">valueToKey</a>(), <a href="qmetaenum.html#keysToValue">keysToValue</a>(), and <a href="qmetaenum.html#valueToKeys">valueToKeys</a>() allow conversion between the integer representation of an enumeration or set value and its literal representation. The <a href="qmetaenum.html#scope">scope</a>() function returns the class scope this enumerator was declared in.</p>
<p>See also <a href="qmetaobject.html">QMetaObject</a>, <a href="qmetamethod.html">QMetaMethod</a>, and <a href="qmetaproperty.html">QMetaProperty</a>.</p>

<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="isFlag"></a>bool QMetaEnum::isFlag () const</h3>
<p>Returns true if this enumerator is used as a flag; otherwise returns false.</p>
<p>When used as flags, enumerators can be combined using the OR operator.</p>
<p>See also <a href="qmetaenum.html#keysToValue">keysToValue</a>() and <a href="qmetaenum.html#valueToKeys">valueToKeys</a>().</p>
<h3 class="fn"><a name="isValid"></a>bool QMetaEnum::isValid () const</h3>
<p>Returns true if this enum is valid (has a name); otherwise returns false.</p>
<p>See also <a href="qmetaenum.html#name">name</a>().</p>
<h3 class="fn"><a name="key"></a>const char * QMetaEnum::key ( int <i>index</i> ) const</h3>
<p>Returns the key with the given <i>index</i>, or 0 if no such key exists.</p>
<p>See also <a href="qmetaenum.html#keyCount">keyCount</a>(), <a href="qmetaenum.html#value">value</a>(), and <a href="qmetaenum.html#valueToKey">valueToKey</a>().</p>
<h3 class="fn"><a name="keyCount"></a>int QMetaEnum::keyCount () const</h3>
<p>Returns the number of keys.</p>
<p>See also <a href="qmetaenum.html#key">key</a>().</p>
<h3 class="fn"><a name="keyToValue"></a>int QMetaEnum::keyToValue ( const char * <i>key</i> ) const</h3>
<p>Returns the integer value of the given enumeration <i>key</i>, or -1 if <i>key</i> is not defined.</p>
<p>For flag types, use <a href="qmetaenum.html#keysToValue">keysToValue</a>().</p>
<p>See also <a href="qmetaenum.html#valueToKey">valueToKey</a>(), <a href="qmetaenum.html#isFlag">isFlag</a>(), and <a href="qmetaenum.html#keysToValue">keysToValue</a>().</p>
<h3 class="fn"><a name="keysToValue"></a>int QMetaEnum::keysToValue ( const char * <i>keys</i> ) const</h3>
<p>Returns the value derived from combining together the values of the <i>keys</i> using the OR operator, or -1 if <i>keys</i> is not defined. Note that the strings in <i>keys</i> must be '|'-separated.</p>
<p>See also <a href="qmetaenum.html#isFlag">isFlag</a>(), <a href="qmetaenum.html#valueToKey">valueToKey</a>(), and <a href="qmetaenum.html#valueToKeys">valueToKeys</a>().</p>
<h3 class="fn"><a name="name"></a>const char * QMetaEnum::name () const</h3>
<p>Returns the name of the enumerator (without the scope).</p>
<p>For example, the <a href="qt.html#AlignmentFlag-enum">Qt::AlignmentFlag</a> enumeration has <tt>AlignmentFlag</tt> as the name and <a href="qt.html">Qt</a> as the scope.</p>
<p>See also <a href="qmetaenum.html#isValid">isValid</a>() and <a href="qmetaenum.html#scope">scope</a>().</p>
<h3 class="fn"><a name="scope"></a>const char * QMetaEnum::scope () const</h3>
<p>Returns the scope this enumerator was declared in.</p>
<p>For example, the <a href="qt.html#AlignmentFlag-enum">Qt::AlignmentFlag</a> enumeration has <tt>Qt</tt> as the scope and <tt>AlignmentFlag</tt> as the name.</p>
<p>See also <a href="qmetaenum.html#name">name</a>().</p>
<h3 class="fn"><a name="value"></a>int QMetaEnum::value ( int <i>index</i> ) const</h3>
<p>Returns the value with the given <i>index</i>; or returns -1 if there is no such value.</p>
<p>See also <a href="qmetaenum.html#keyCount">keyCount</a>(), <a href="qmetaenum.html#key">key</a>(), and <a href="qmetaenum.html#keyToValue">keyToValue</a>().</p>
<h3 class="fn"><a name="valueToKey"></a>const char * QMetaEnum::valueToKey ( int <i>value</i> ) const</h3>
<p>Returns the string that is used as the name of the given enumeration <i>value</i>, or 0 if <i>value</i> is not defined.</p>
<p>For flag types, use <a href="qmetaenum.html#valueToKeys">valueToKeys</a>().</p>
<p>See also <a href="qmetaenum.html#isFlag">isFlag</a>() and <a href="qmetaenum.html#valueToKeys">valueToKeys</a>().</p>
<h3 class="fn"><a name="valueToKeys"></a><a href="qbytearray.html">QByteArray</a> QMetaEnum::valueToKeys ( int <i>value</i> ) const</h3>
<p>Returns a byte array of '|'-separated keys that represents the given <i>value</i>.</p>
<p>See also <a href="qmetaenum.html#isFlag">isFlag</a>(), <a href="qmetaenum.html#valueToKey">valueToKey</a>(), and <a href="qmetaenum.html#keysToValue">keysToValue</a>().</p>
