Hi,
I'm a newbie, and have (I think) successfully installed Qt integration, using Qt 4.8.0 into Eclipse Indigo. I successfully followed the basic AddressBook example which ran fine.

However, now when I click and open a .ui file, the QtDesigner menu and the Qt Widget Box remain greyed out. Qt C++ Properties remains active, so I can change properties of a ui form, but can't add any new widgets. I've tried a restart, and creating a new blank Qt project, but the problem remains.

I'm sure I'm missing something obvious, but it's not obvious to me, and I can't find any past solutions. Any suggestions?
Cheers,
Tom
