Integrate Designer into own Ui

[NoRulez]

I mean the QtDesigner Module, I didn't find any examples for using QDesignerFormEditorInterfacefor example

Because it's a niche and complicated subject and it's not possible to have a 20-line example of using the component for your own project. Usually you access it from within Designer plugins. I don't know how your design process looks like but unless you are designing Qt forms, there won't be much benefit from QDesignerFormEditorInterface. And if you are after designing Qt forms then it might be easier to deploy Designer (optionally with a custom plugin extending it to fit your needs better) to the client and using UiTools to load the interface into your main app after it's designed.
