QtPropertyBrowser not handling Q_PROPERTY Notify event

LeifZars

Starting with the example object_controller from qt-solutions I implemented a few objects with Q_PROPERTY attributes.
@
Q_PROPERTY(int ModuleId READ moduleId WRITE setModuleId NOTIFY moduleIdChanged)
@
Everything works except when I change the field programticly the PropertyBrowser doesn't update. The moduleIdChanged signal is emitted but nothing is attached. What could I be doing wrong.

Welcome to DevNet!

Have you connected moduleIdChanged signal to any slots in the PropertyBrowser?

LeifZars

I am not sure I understand. I don't believe the QObjects that I am visualizing via the Property Browser contain such a signal. Maybe I am misunderstanding.

FYI this is the example I used to module my code around: https://qt.gitorious.org/qt-solutions/qt-solutions/source/fd22bee22274975c56f1c10d87ee9fd2c0818f83:qtpropertybrowser/examples/object_controller

You have implemented a signal that notifies about the changes in the objects.
To get these notifications in the property browser you need to connect the browser's slot to this signal.

It was my imprecision that the PropertyBrowser automatically did that, but maybe not.

I don't think it is a generic property browser for any QObject based classes.
Do you use QtIntPropertyManager::addProperty() to add ModuleId to the properties hierarchy?
Have you implemented your property browser based on QtAbstractPropertyBrowser?

"Here":http://doc.qt.digia.com/qq/qq18-propertybrowser.html is an article that explains the property browser framework.

Sorry for the long delay.

Yes I do use addProperty .

I am using QtTreePropertyBrowser, it is based on the QtAbstractPropertyBrowser.

The method I use, addClassProperties, is taken from object_controller qtPropertyBrowser example. It doesn't appear to handle change events, so I will have to add that.

LeifZars

I am also using QtVariantPropertyManager, it seems that I will have to modify this. I don't see how else I could connect the properties change signal to the managed widget.

LeifZars

I am having trouble determining how I should implement this. Any ideas.

Also per
http://www.wiki.crossplatform.ru/index.php/The_Property_Browser_Framework If you search for the word sync on that page, it says that the is internally handled.
