Qt Solutions Component: Property Browser
|
||
|
|
|
||
|
|
A property browser framework enabling the user to edit a set of
|
||
|
|
properties.
|
||
|
|
|
||
|
|
The framework provides a browser widget that displays the given
|
||
|
|
properties with labels and corresponding editing widgets (e.g.
|
||
|
|
line edits or comboboxes). The various types of editing widgets
|
||
|
|
are provided by the framework's editor factories: For each
|
||
|
|
property type, the framework provides a property manager (e.g.
|
||
|
|
QtIntPropertyManager and QtStringPropertyManager) which can be
|
||
|
|
associated with the preferred editor factory (e.g.
|
||
|
|
QtSpinBoxFactory and QtLineEditFactory). The framework also
|
||
|
|
provides a variant based property type with corresponding variant
|
||
|
|
manager and factory. Finally, the framework provides three
|
||
|
|
ready-made implementations of the browser widget:
|
||
|
|
QtTreePropertyBrowser, QtButtonPropertyBrowser and
|
||
|
|
QtGroupBoxPropertyBrowser.
|
||
|
|
|
||
|
|

||
|
|
- QtAbstractPropertyManager - initializeProperty() and
|
||
|
|
uninitializeProperty() without const modifier now
|
||
|
|

|
|
properties added
