Answer 1

In Swing, you have two options for layout: do everything manually or let a LayoutManager handle it for you.

Calling setSize() will only work when you're not using a LayoutManager. Since you're using a GridLayout you'll have to use other ways to specify what you want.

Try calling setPreferredSize() and setMinimumSize().

Answer 2

but setXxxSize (for ContainersChilds) works as chaims if you change from setSize() (for TopLayoutContainer) to setPreferredSize() and you have to call pack() before setVisible()

Answer 3

Two things - firstly you should be setting the preferredSize of the scrollpane, but secondly, trying to resize it inside the componentResized handler isn't a very effective technique because the 'resized' events aren't continuous.
