<h2>Detailed Description</h2>
|
|
<p>The QtVariantProperty class is a convenience class handling <a href="http://qt.nokia.com/doc/4.6/qvariant.html">QVariant</a> based properties.</p>
|
|
<p>QtVariantProperty provides additional API: A property's type, value type, attribute values and current value can easily be retrieved using the <a href="qtvariantproperty.html#propertyType">propertyType</a>(), <a href="qtvariantproperty.html#valueType">valueType</a>(), <a href="qtvariantproperty.html#attributeValue">attributeValue</a>() and <a href="qtvariantproperty.html#value">value</a>() functions respectively. In addition, the attribute values and the current value can be set using the corresponding <a href="qtvariantproperty.html#setValue">setValue</a>() and <a href="qtvariantproperty.html#setAttribute">setAttribute</a>() functions.</p>
|
|
<p>For example, instead of writing:</p>
|
|
<pre> QtVariantPropertyManager *variantPropertyManager;
|
|
QtProperty *property;
|
|
|
|
variantPropertyManager->setValue(property, 10);</pre>
|
|
<p>you can write:</p>
|
|
<pre> QtVariantPropertyManager *variantPropertyManager;
|
|
QtVariantProperty *property;
|
|
|
|
property->setValue(10);</pre>
|
|
<p>QtVariantProperty instances can only be created by the <a href="qtvariantpropertymanager.html">QtVariantPropertyManager</a> class.</p>
|
|
<p>See also <a href="qtproperty.html">QtProperty</a>, <a href="qtvariantpropertymanager.html">QtVariantPropertyManager</a>, and <a href="qtvarianteditorfactory.html">QtVariantEditorFactory</a>.</p>

|
<h3 class="fn"><a name="QtVariantProperty"></a>QtVariantProperty::QtVariantProperty ( <a href="qtvariantpropertymanager.html">QtVariantPropertyManager</a> * <i>manager</i> ) <tt> [protected]</tt></h3>
|
|
<p>Creates a variant property using the given <i>manager</i>.</p>
|
|
<p>Do not use this constructor to create variant property instances; use the <a href="qtvariantpropertymanager.html#addProperty">QtVariantPropertyManager::addProperty</a>() function instead. This constructor is used internally by the <a href="qtvariantpropertymanager.html#createProperty">QtVariantPropertyManager::createProperty</a>() function.</p>
|
|
<p>See also <a href="qtvariantpropertymanager.html">QtVariantPropertyManager</a>.</p>
|
|
<h3 class="fn"><a name="dtor.QtVariantProperty"></a>QtVariantProperty::~QtVariantProperty ()</h3>
|
|
<p>Destroys this property.</p>
|
|
<p>See also <a href="qtproperty.html#dtor.QtProperty">QtProperty::~QtProperty</a>().</p>
|
|
<h3 class="fn"><a name="attributeValue"></a><a href="http://qt.nokia.com/doc/4.6/qvariant.html">QVariant</a> QtVariantProperty::attributeValue ( const <a href="http://qt.nokia.com/doc/4.6/qstring.html">QString</a> & <i>attribute</i> ) const</h3>
|
|
<p>Returns this property's value for the specified <i>attribute</i>.</p>
|
|
<p><a href="qtvariantpropertymanager.html">QtVariantPropertyManager</a> provides a couple of related functions: <a href="qtvariantpropertymanager.html#attributes">attributes()</a> and <a href="qtvariantpropertymanager.html#attributeType">attributeType()</a>.</p>
|
|
<p>See also <a href="qtvariantproperty.html#setAttribute">setAttribute</a>().</p>
|
|
<h3 class="fn"><a name="propertyType"></a>int QtVariantProperty::propertyType () const</h3>
|
|
<p>Returns this property's type.</p>
|
|
<p><a href="qtvariantpropertymanager.html">QtVariantPropertyManager</a> provides several related functions: <a href="qtvariantpropertymanager.html#enumTypeId">enumTypeId()</a>, <a href="qtvariantpropertymanager.html#flagTypeId">flagTypeId()</a> and <a href="qtvariantpropertymanager.html#groupTypeId">groupTypeId()</a>.</p>

|
|
<p>Sets the <i>attribute</i> of property to <i>value</i>.</p>
|
|
<p><a href="qtvariantpropertymanager.html">QtVariantPropertyManager</a> provides the related <a href="qtvariantpropertymanager.html#setAttribute">setAttribute()</a> function.</p>

|
|
<h3 class="fn"><a name="setValue"></a>void QtVariantProperty::setValue ( const <a href="http://qt.nokia.com/doc/4.6/qvariant.html">QVariant</a> & <i>value</i> )</h3>
|
|
<p>Sets the value of this property to <i>value</i>.</p>
|
|
<p>The specified <i>value</i> must be of the type returned by <a href="qtvariantproperty.html#valueType">valueType</a>(), or of a type that can be converted to <a href="qtvariantproperty.html#valueType">valueType</a>() using the <a href="http://qt.nokia.com/doc/4.6/qvariant.html#canConvert">QVariant::canConvert</a>() function; otherwise this function does nothing.</p>
