TextField problem.

[miller.bartek]

Hi everyone,
what I wanted to achieve was a resizeable JTextField of width equal to a frame width. Successfully I did it, but I have some doubts about the another solution which unfortunately doesn't work.

I attached a print screen showing my code in two different versions and results.
I would be grateful for explanation.

Thanks in advance.

API says:
JPanel() - Creates a new JPanel with a double buffer and a flow layout.
JPanel(LayoutManager layout) - Create a new buffered JPanel with the specified layout manager

edit: My question is: Why in the first example the goal is achieved and in the second one a JTextField is squeezed in the middle?

Please go into greater detail regarding your question. Thanks.

In the first example you use a Border Layout and in the second you use a Flow Layout.
Look up Layout Managers and how they work. They can be hard to understand without
experimenting.

Thank you for your help.
I read a little bit about Layouts and it seems to be clear.
