Sure. What you basically are doing, is creating your own widget. Just create a new QWidget-based widget using the File -> New wizard, and design the .ui the way you like it. Now, design the .ui in which you want to use those widgets. Drop in a QWidget on there, right click it, and use the Promote to… item to promote the widget to your new widget.

Thanks. Now when I Promote To, I don’t see my widget form listed, I only get to choose from the existing Q classes for the base class and a new class name. Or am i supposed to specifiy an include file? If so, I don’t know how to get those from a form.

So say my new widget is saved in a form called pad.ui. When I promote a qwidget on another form, I don’t see how to specify pad.ui.

You have to put QFrame (or whatever you derive your widget from) as the base class, Pad (I assume that’s the name) as the class name and pad.h as the header file name.

Ok, thanks. That will have to do. I was hoping for a way to instantiate the form in Designer. Funny there isn’t a widget that will load a ui form.

Well, you can always open a suggestion ticket for that feature here [bugreports.qt.nokia.com]

Thanks, I should make a request. Today I wrote my own plugin that instantiates a form. Not too difficult, as long as you are familiar with plugins.

There is already code in Qt to create a widget from a .ui file at runtime: QFormBuilder. Or do you mean that you wrote a plugin for Designer that allows you to add a .ui file as a widget on your form? That is interesting!

Yes, it’s a custom widget plugin for Designer, to instantiate an arbitrary .ui form. Seems very useful, so I’m surprised the capability does not already exist.
