<hr><a name="details"></a><h2>Detailed Description</h2>
<p> The TQMetaProperty class stores meta data about a property.
<p>
<p> Property meta data includes <a href="#type">type</a>(), <a href="#name">name</a>(), and whether a property
is <a href="#writable">writable</a>(), <a href="#designable">designable</a>() and <a href="#stored">stored</a>().
<p> The functions <a href="#isSetType">isSetType</a>(), <a href="#isEnumType">isEnumType</a>() and <a href="#enumKeys">enumKeys</a>() provide
further information about a property's type. The conversion
functions <a href="#keyToValue">keyToValue</a>(), <a href="#valueToKey">valueToKey</a>(), <a href="#keysToValue">keysToValue</a>() and
<a href="#valueToKeys">valueToKeys</a>() allow conversion between the integer representation
of an enumeration or set value and its literal representation.
<p> Actual property values are set and received through <a href="tqobject.html">TQObject</a>'s set
and get functions. See <a href="tqobject.html#setProperty">TQObject::setProperty</a>() and
<a href="tqobject.html#property">TQObject::property</a>() for details.
<p> You receive meta property data through an object's <a href="metaobjects.html#meta-object">meta object</a>.
See <a href="tqmetaobject.html#property">TQMetaObject::property</a>() and <a href="tqmetaobject.html#propertyNames">TQMetaObject::propertyNames</a>() for
details.
<p>See also <a href="objectmodel.html">Object Model</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn>bool <a name="designable"></a>TQMetaProperty::designable ( <a href="tqobject.html">TQObject</a> * o = 0 ) const
</h3> Returns TRUE if the property is designable for object <em>o</em>;
otherwise returns FALSE.
<p> If no object <em>o</em> is given, the function returns a static
approximation.
<h3 class=fn><a href="tqstrlist.html">TQStrList</a> <a name="enumKeys"></a>TQMetaProperty::enumKeys () const
</h3>
Returns the possible enumeration keys if this property is an
enumeration type (or a set type).
<p> <p>See also <a href="#isEnumType">isEnumType</a>().
<h3 class=fn>bool <a name="isEnumType"></a>TQMetaProperty::isEnumType () const
</h3>
<p> Returns TRUE if the property's type is an enumeration value;
otherwise returns FALSE.
<p> <p>See also <a href="#isSetType">isSetType</a>() and <a href="#enumKeys">enumKeys</a>().
<h3 class=fn>bool <a name="isSetType"></a>TQMetaProperty::isSetType () const
</h3>
<p> Returns TRUE if the property's type is an enumeration value that
is used as set, i.e. if the enumeration values can be OR-ed
together; otherwise returns FALSE. A set type is implicitly also
an enum type.
<p> <p>See also <a href="#isEnumType">isEnumType</a>() and <a href="#enumKeys">enumKeys</a>().
<h3 class=fn>int <a name="keyToValue"></a>TQMetaProperty::keyToValue ( const char * key ) const
</h3>
Converts the enumeration key <em>key</em> to its integer value.
<p> For set types, use <a href="#keysToValue">keysToValue</a>().
<p> <p>See also <a href="#valueToKey">valueToKey</a>(), <a href="#isSetType">isSetType</a>(), and <a href="#keysToValue">keysToValue</a>().
<h3 class=fn>int <a name="keysToValue"></a>TQMetaProperty::keysToValue ( const <a href="tqstrlist.html">TQStrList</a> & keys ) const
</h3>
Converts the list of keys <em>keys</em> to their combined (OR-ed)
integer value.
<p> <p>See also <a href="#isSetType">isSetType</a>() and <a href="#valueToKey">valueToKey</a>().
<h3 class=fn>const char * <a name="name"></a>TQMetaProperty::name () const
</h3>
<p> Returns the name of the property.
<h3 class=fn>bool <a name="reset"></a>TQMetaProperty::reset ( <a href="tqobject.html">TQObject</a> * o ) const
</h3>
Tries to reset the property for object <em>o</em> with a reset method.
On success, returns TRUE; otherwise returns FALSE.
<p> Reset methods are optional, usually only a few properties support
them.
<h3 class=fn>bool <a name="scriptable"></a>TQMetaProperty::scriptable ( <a href="tqobject.html">TQObject</a> * o = 0 ) const
</h3>
Returns TRUE if the property is scriptable for object <em>o</em>;
otherwise returns FALSE.
<p> If no object <em>o</em> is given, the function returns a static
approximation.
<h3 class=fn>bool <a name="stored"></a>TQMetaProperty::stored ( <a href="tqobject.html">TQObject</a> * o = 0 ) const
</h3>
Returns TRUE if the property shall be stored for object <em>o</em>;
otherwise returns FALSE.
<p> If no object <em>o</em> is given, the function returns a static
approximation.
<h3 class=fn>const char * <a name="type"></a>TQMetaProperty::type () const
</h3>
<p> Returns the type of the property.
<h3 class=fn>const char * <a name="valueToKey"></a>TQMetaProperty::valueToKey ( int value ) const
</h3>
Converts the enumeration value <em>value</em> to its literal key.
<p> For set types, use <a href="#valueToKeys">valueToKeys</a>().
<p> <p>See also <a href="#isSetType">isSetType</a>() and <a href="#valueToKeys">valueToKeys</a>().
<h3 class=fn><a href="tqstrlist.html">TQStrList</a> <a name="valueToKeys"></a>TQMetaProperty::valueToKeys ( int value ) const
</h3>
Converts the set value <em>value</em> to a list of keys.
<p> <p>See also <a href="#isSetType">isSetType</a>() and <a href="#valueToKey">valueToKey</a>().
<h3 class=fn>bool <a name="writable"></a>TQMetaProperty::writable () const
</h3>
<p> Returns TRUE if the property is writable; otherwise returns FALSE.
