Help needed in adding QWidget and other objects to a QHBoxLayout

[wysota]

I am using Qt 3.3.5

Ouch Can you consider upgrading to Qt 4.4.3?

I can't see QWidget lsited under 'Containers'in my QtDesigner, hence I am creating one at runtime.

What do you need QWidget for? In your case I would recommend using QSplitter and this one is available in Designer from the layout toolbar. If you use it, you'll be able to point and click everything in Designer. Without the splitter you can do that too - I'm not sure what do you need the pure QWidget for. For the "document view" insert some widget like QFrame and promote it you your class by right clicking it and choosing "Promote to".

While using QHBoxLayout, to view the toolbars I need to put spacing = 25, if not the toolbars are covered by the mainWidget

Either you have done something wrong or... no, there is no "or"... this shouldn't happen by itself.

Here is something I created quickly in Designer, maybe it will be helpful for you. It's probably not perfect, I haven't been using Qt3 Designer for over two years
