Detailed Description

The QtSizePolicyPropertyManager provides and manages QSizePolicy properties.

A size policy property has nested horizontalPolicy, verticalPolicy, horizontalStretch and verticalStretch 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 QtIntPropertyManager and QtEnumPropertyManager objects. These managers can be retrieved using the subIntPropertyManager() and subEnumPropertyManager() functions respectively. In order to provide editing widgets for the subproperties in a property browser widget, these managers must be associated with editor factories.

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