<h2>Detailed Description</h2>
|
||
|
|
<p>The QtRectFPropertyManager provides and manages <a href="http://qt.nokia.com/doc/4.6/qrectf.html">QRectF</a> properties.</p>
|
||
|
|
<p>A rectangle property has nested <i>x</i>, <i>y</i>, <i>width</i> and <i>height</i> subproperties. The top-level property's value can be retrieved using the <a href="qtrectfpropertymanager.html#value">value</a>() function, and set using the <a href="qtrectfpropertymanager.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="qtrectfpropertymanager.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>A rectangle property also has a constraint rectangle which can be retrieved using the <a href="qtrectfpropertymanager.html#constraint">constraint</a>() function, and set using the <a href="qtrectfpropertymanager.html#setConstraint">setConstraint</a>() slot.</p>
|
||
|
|
<p>In addition, QtRectFPropertyManager provides the <a href="qtrectfpropertymanager.html#valueChanged">valueChanged</a>() signal which is emitted whenever a property created by this manager changes, and the <a href="qtrectfpropertymanager.html#constraintChanged">constraintChanged</a>() signal which is emitted whenever such a property changes its constraint rectangle.</p>
|
||
|
|
<p>See also <a href="qtabstractpropertymanager.html">QtAbstractPropertyManager</a>, <a href="qtdoublepropertymanager.html">QtDoublePropertyManager</a>, and <a href="qtrectpropertymanager.html">QtRectPropertyManager</a>.</p>
