Help needed in adding QWidget and other objects to a QHBoxLayout

[wysota]

1. Unfortunately I have to use 3.3.5 as I need to enhance an old project that was developed using 3.3.5

Too bad, it'd be much simpler in Qt4.

3. I don't see QSplitter in my QtDesigner

It's there. But not in the widget toolbox but in the layout toolbar to the right of the grid layout icon. Select two widgets (like the listbox and the frame) and the icon will become active.

4. Though I can create a frame, there is no 'Promote to' option when I right click it .

Right, sorry... the mechanism is a bit different in Qt3. Go to Tools->Custom->Edit custom widgets. If you fill the form that opens, the widget of your choice will become available in the "Custom" section of the widget toolbox.

I really appreciate your feedback ... as I am going round in circles, trying to get this feature together, while hitting roadblocks everytime...

Don't worry, you'll manage to do it.

am I limited because of qt 3.3.5?

Qt3 technology is about 10 years old. Much has happened since then. What you want to achieve would take about 10-15 minutes for a skilled Qt4 programmer.

is there any possible workaround to get it to work .... please advise.

You don't have to work around anything. It's just more work in Qt3 than in Qt4 as the latter contains some components that would ease your job. Still the task is relatively easy just don't overcomplicate things. Try working on the form I gave you, it practically contains everything you need.
