Q_PROPERTY with binding to designer

[anda_skoa]

That's exactly my problem:
My ui is a

mainWindow : QMainWindow

mainWindow : QMainWindow

To copy to clipboard, switch view to plain text mode 

when I select the mainWindow in the object-tree, there are only three categories in the property editor: QObject, QWidget and QMainWindow. There is no Category as the name of my class "mainWindow" (see following pic).

The type is QMainWindow, as you can see in the second column in the object tree view.

even if I build two new classes (Form1 : QWidget AND Form2 : Form1) and i set a Q_Property with the name smallText in Form1, i see in the property-editor of "Form2" neither a category "Form1" nor a property "smallText" in any other category.

Does the designer plugin that provides "Form1" create instances of Form1 or maybe just QWidget?
Does Form1 have the Q_OBJECT macro additional to the Q_PROPERTY macro?

Cheers,
