I'm currently working on a project using the multipage component to develop an interface with tabs. I have the following problem:

I found out by editing the Multipage you can add different tools to the different tabpages.When I select the toolbox to add them I don't seem to find some components which I find in the default toolbox (ex. Data control tool)

Also the different objects you add(like buttons, labels, etc..) don't appear in the properties window, so you can't set porperties like you normally can.

Anyone who has experience using multipages, be free to answer my questions.
