<h2>Detailed Description</h2>
|
||
|
|
<p>The QtProperty class encapsulates an instance of a property.</p>
|
||
|
|
<p>Properties are created by objects of <a href="qtabstractpropertymanager.html">QtAbstractPropertyManager</a> subclasses; a manager can create properties of a given type, and is used in conjunction with the <a href="qtabstractpropertybrowser.html">QtAbstractPropertyBrowser</a> class. A property is always owned by the manager that created it, which can be retrieved using the <a href="qtproperty.html#propertyManager">propertyManager</a>() function.</p>
|
||
|
|
<p>QtProperty contains the most common property attributes, and provides functions for retrieving as well as setting their values:</p>

</table></p>
|
||
|
|
<p>It is also possible to nest properties: QtProperty provides the <a href="qtproperty.html#addSubProperty">addSubProperty</a>(), <a href="qtproperty.html#insertSubProperty">insertSubProperty</a>() and <a href="qtproperty.html#removeSubProperty">removeSubProperty</a>() functions to manipulate the set of subproperties. Use the <a href="qtproperty.html#subProperties">subProperties</a>() function to retrieve a property's current set of subproperties. Note that nested properties are not owned by the parent property, i.e. each subproperty is owned by the manager that created it.</p>

|
|
<h3 class="fn"><a name="QtProperty"></a>QtProperty::QtProperty ( <a href="qtabstractpropertymanager.html">QtAbstractPropertyManager</a> * <i>manager</i> ) <tt> [protected]</tt></h3>
|
||
|
|
<p>Creates a property with the given <i>manager</i>.</p>
|
||
|
|
<p>This constructor is only useful when creating a custom <a href="qtproperty.html">QtProperty</a> subclass (e.g. <a href="qtvariantproperty.html">QtVariantProperty</a>). To create a regular <a href="qtproperty.html">QtProperty</a> object, use the <a href="qtabstractpropertymanager.html#addProperty">QtAbstractPropertyManager::addProperty</a>() function instead.</p>
|
||
|
|
<p>See also <a href="qtabstractpropertymanager.html#addProperty">QtAbstractPropertyManager::addProperty</a>().</p>
|
||
|
|
<h3 class="fn"><a name="dtor.QtProperty"></a>QtProperty::~QtProperty () <tt> [virtual]</tt></h3>
|
||
|
|
<p>Destroys this property.</p>
|
||
|
|
<p>Note that subproperties are detached but not destroyed, i.e. they can still be used in another context.</p>
|
||
|
|
<p>See also <a href="qtabstractpropertymanager.html#clear">QtAbstractPropertyManager::clear</a>().</p>
|
||

|
<h3 class="fn"><a name="addSubProperty"></a>void QtProperty::addSubProperty ( QtProperty * <i>property</i> )</h3>
|
||
|
|
<p>Appends the given <i>property</i> to this property's subproperties.</p>
|
||
|
|
<p>If the given <i>property</i> already is added, this function does nothing.</p>
|
||
|
|
<p>See also <a href="qtproperty.html#insertSubProperty">insertSubProperty</a>() and <a href="qtproperty.html#removeSubProperty">removeSubProperty</a>().</p>

|
<p>Inserts the given <i>property</i> after the specified <i>precedingProperty</i> into this property's list of subproperties. If <i>precedingProperty</i> is 0, the specified <i>property</i> is inserted at the beginning of the list.</p>
|
||
|
|
<p>If the given <i>property</i> already is inserted, this function does nothing.</p>
