<h2>Detailed Description</h2>
|
||
|
|
<p>The QtVariantPropertyManager class provides and manages <a href="http://qt.nokia.com/doc/4.6/qvariant.html">QVariant</a> based properties.</p>
|
||
|
|
<p>QtVariantPropertyManager provides the <a href="qtvariantpropertymanager.html#addProperty">addProperty</a>() function which creates <a href="qtvariantproperty.html">QtVariantProperty</a> objects. The <a href="qtvariantproperty.html">QtVariantProperty</a> class is a convenience class handling <a href="http://qt.nokia.com/doc/4.6/qvariant.html">QVariant</a> based properties inheriting <a href="qtproperty.html">QtProperty</a>. A <a href="qtproperty.html">QtProperty</a> object created by a QtVariantPropertyManager instance can be converted into a <a href="qtvariantproperty.html">QtVariantProperty</a> object using the <a href="qtvariantpropertymanager.html#variantProperty">variantProperty</a>() function.</p>
|
||
|
|
<p>The property's value can be retrieved using the <a href="qtvariantpropertymanager.html#value">value</a>(), and set using the <a href="qtvariantpropertymanager.html#setValue">setValue</a>() slot. In addition the property's type, and the type of its value, can be retrieved using the <a href="qtvariantpropertymanager.html#propertyType">propertyType</a>() and <a href="qtvariantpropertymanager.html#valueType">valueType</a>() functions respectively.</p>
|
||
|
|
<p>A property's type is a <a href="http://qt.nokia.com/doc/4.6/qvariant.html#Type-enum">QVariant::Type</a> enumerator value, and usually a property's type is the same as its value type. But for some properties the types differ, for example for enums, flags and group types in which case QtVariantPropertyManager provides the <a href="qtvariantpropertymanager.html#enumTypeId">enumTypeId</a>(), <a href="qtvariantpropertymanager.html#flagTypeId">flagTypeId</a>() and <a href="qtvariantpropertymanager.html#groupTypeId">groupTypeId</a>() functions, respectively, to identify their property type (the value types are <a href="http://qt.nokia.com/doc/4.6/qvariant.html#Type-enum">QVariant::Int</a> for the enum and flag types, and <a href="http://qt.nokia.com/doc/4.6/qvariant.html#Type-enum">QVariant::Invalid</a> for the group type).</p>
|
||
|
|
<p>Use the <a href="qtvariantpropertymanager.html#isPropertyTypeSupported">isPropertyTypeSupported</a>() function to check if a particular property type is supported. The currently supported property types are:</p>

<p>The attributes for a given property type can be retrieved using the <a href="qtvariantpropertymanager.html#attributes">attributes</a>() function. Each attribute has a value type which can be retrieved using the <a href="qtvariantpropertymanager.html#attributeType">attributeType</a>() function, and a value accessible through the <a href="qtvariantpropertymanager.html#attributeValue">attributeValue</a>() function. In addition, the value can be set using the <a href="qtvariantpropertymanager.html#setAttribute">setAttribute</a>() slot.</p>
|
||
|
|
<p>QtVariantManager also provides the <a href="qtvariantpropertymanager.html#valueChanged">valueChanged</a>() signal which is emitted whenever a property created by this manager change, and the <a href="qtvariantpropertymanager.html#attributeChanged">attributeChanged</a>() signal which is emitted whenever an attribute of such a property changes.</p>
