Thx again Ratzz. I am gonna apply it to the project I am working on and let you know how it goes.

I was having some issues with custom header on the tableView as the widgets tend to overlap when
I resize them and resulting in invoking wrong signals associated with each pushbuttons. When
I asked the question, I meant literally placing widgets on header sections as the sections do not
seem to overlap at all.

Those things I've done so far, I've modeled after samples I've found on the internet.
