<h2>Detailed Description</h2>
|
||
|
|
<p>The QtPointFPropertyManager provides and manages <a href="http://qt.nokia.com/doc/4.6/qpointf.html">QPointF</a> properties.</p>
|
||
|
|
<p>A point property has nested <i>x</i> and <i>y</i> subproperties. The top-level property's value can be retrieved using the <a href="qtpointfpropertymanager.html#value">value</a>() function, and set using the <a href="qtpointfpropertymanager.html#setValue">setValue</a>() slot.</p>
|
||
|
|
<p>The subproperties are created by a <a href="qtdoublepropertymanager.html">QtDoublePropertyManager</a> object. This manager can be retrieved using the <a href="qtpointfpropertymanager.html#subDoublePropertyManager">subDoublePropertyManager</a>() function. In order to provide editing widgets for the subproperties in a property browser widget, this manager must be associated with an editor factory.</p>
|
||
|
|
<p>In addition, QtPointFPropertyManager provides the <a href="qtpointfpropertymanager.html#valueChanged">valueChanged</a>() signal which is emitted whenever a property created by this manager changes.</p>
|
||
|
|
<p>See also <a href="qtabstractpropertymanager.html">QtAbstractPropertyManager</a>, <a href="qtdoublepropertymanager.html">QtDoublePropertyManager</a>, and <a href="qtpointpropertymanager.html">QtPointPropertyManager</a>.</p>
