\class QtGroupBoxPropertyBrowser
|
|
|
|
\brief The QtGroupBoxPropertyBrowser class provides a QGroupBox
|
|
based property browser.
|
|
|
|
A property browser is a widget that enables the user to edit a
|
|
given set of properties. Each property is represented by a label
|
|
specifying the property's name, and an editing widget (e.g. a line
|
|
edit or a combobox) holding its value. A property can have zero or
|
|
more subproperties.
|
|
|
|
QtGroupBoxPropertyBrowser provides group boxes for all nested
|
|
properties, i.e. subproperties are enclosed by a group box with
|
|
the parent property's name as its title. For example:
|
|
|
|
\image qtgroupboxpropertybrowser.png
|
|
|
|
Use the QtAbstractPropertyBrowser API to add, insert and remove
|
|
properties from an instance of the QtGroupBoxPropertyBrowser
|
|
class. The properties themselves are created and managed by
|
|
implementations of the QtAbstractPropertyManager class.
