Detailed Description

The QtPointFPropertyManager provides and manages QPointF properties.

\inmodule QtDesigner

Since: 4.4

A point property has nested x and y subproperties. The top-level property's value can be retrieved using the value() function, and set using the setValue() slot.

The subproperties are created by a QtDoublePropertyManager object. This manager can be retrieved using the subDoublePropertyManager() function. In order to provide editing widgets for the subproperties in a property browser widget, this manager must be associated with an editor factory.

In addition, QtPointFPropertyManager provides the valueChanged() signal which is emitted whenever a property created by this manager changes.
