Detailed Description

The QtColorPropertyManager provides and manages QColor properties.

A color property has nested red, green and blue 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 QtIntPropertyManager object. This manager can be retrieved using the subIntPropertyManager() 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, QtColorPropertyManager provides the valueChanged() signal which is emitted whenever a property created by this manager changes.

◆ subIntPropertyManager()

QtIntPropertyManager * QtColorPropertyManager::subIntPropertyManager ( ) const

Returns the manager that produces the nested red, green and blue subproperties.

In order to provide editing widgets for the subproperties in a property browser widget, this manager must be associated with an editor factory.

\reimp

Reimplemented from QtAbstractPropertyManager.

◆ value()

QColor QtColorPropertyManager::value ( const QtProperty * property ) const

Returns the given property's value.

If the given property is not managed by this manager, this function returns an invalid color.

signal

This signal is emitted whenever a property created by this manager changes its value, passing a pointer to the property and the new value as parameters.
