Line Break in FlowLayout of Panel

[Nadine]

Hi there,

the following problem occurred to me:

1)
I have a scrollPane and within that a Panel with several components
(Choice, TextField, CheckBox, ...).
It all works fine, except for the fact that it puts all of the
components in one row.
I just want to have 2 components in each row...

I tried the GridLayout, as it should fill the rows from left to right
first; instead it fills the columns first.

The problem is, that the number of components that can show up is
flexible and is calculated dynamically.

Part of the code:
[...]
panel1.setLayout(new FlowLayout(FlowLayout.CENTER, 50, 20));
//panel1.setLayout(new GridLayout(2 ,4, 20, 20));

[...]
panel1.add((java.awt.Component)o[i++]);
panel1.add((java.awt.Component)o[i]);

[...]
scrollPane1.add(panel1);
scrollPane1.getVAdjustable().setUnitIncrement(1);
scrollPane1.getHAdjustable().setUnitIncrement(1);
panel4.add(scrollPane1);
scrollPane1.setBounds(250, 100, 750, 95);
pack();


2)
Is there a possiblity to color the items of a List when a specific
event takes place?

... as far as it has room to do so.

Standardbehaviour of Gridlayout. Just resort your insertions...

... or use GridBagLayout (First Component with GridBagConstraints.width=1,
second Component will require
GridBagConstraints.width=GridBagConstraints.REMAINDER)

Are you talking about AWT or Swing?

With AWT: No.
With Swing: Sure. Just make yourself confident with ListCellRenderers.

Have a nice day

BTW: this is a German group. Preferably most people here like to read
articles in German.

Or, much better, use FormLayout (www.jgoodies.com). The GridBagLayout is a
perfect possibility to be confused by your own code...
