swing Null layout

[satish]

Hi,


I am new to using Swing and I need to create a front-end for a project using
swing. There are many buttons and other controls on the screen at different
locations. I am using the JBuilder 5 IDE for putting the controls on the
screen. I am finding it difficult to place all the controls on the wherever
I want to.I could able to do it by creating too many panles ,setting their
layouts etc...which I feel is a rediuos process..The main problem I find
is using the layout managers, border or flow etc,,,which try to set the controls
on their own without the developer's intervention. alternatively I created
the same layout using JBuilder in 10 mins using the NULL Layout..which is
very good and seems to be quiet simple. But then what is the advantage of
using the tedious layout managers and why is it that we are not supposed
to use the Null layout as told by my friend? I would be happy if anyone could
take time to solve my doubts.

Regards

Satish

Because when the user resizes the frame all your controls are in, the layout
managers automatically rearrange the controls to continue to look good,
whereas the null layout doesn't.

Hi Paul,

Thanks for your response and also for a very good answer. Now I am conviced
that I must use a layout manager, but could you please tell me which layout
manager I should use inorder to create a screen with many controls at different
locations?

You will probably get the best result if you use GridBagLayout but its not
a very nice thing to work with, look at using boxes they should make it much
easier for you and the nice thing is you can add glues,struts,rigid areas
and spacers to get the appearance you want no matter how the user resizes
your GUI.

You should use a layout manager when your front-end is supposed to be resized
dinamically by the user... the layout manager will fit the new size.

According to the help documentation provided with JBuilder:
"Because these layouts[null and XYlayout] are absolute positioning, components

do not adjust well when you resize the parent containers. These layouts
also do not adjust well to differences in users and systems, and therefore,
are not portable layouts."

The specific layout that you should switch to after prototyping within
JBuilder depends on the layout you are trying to achieve. In the samples
directory there are examples of different layouts(mostly null and
FlowLayout) but also includes a project for CardLayout which may interest

you.
