hi,

I am using a multi column JTextpane. The main problem is that there is no space among all columns. The user is unable to read the data properly by differenciating among columns. The user wants there should be gutter space after each column. So that, the matter in each column can be read in better way. I am using the following code to divide the JTextPane into columns:



Any Idea?>

Hi,

I am new to Java. I am Creating a Editor Application in Java. Initally this applcation has a JTextPane(name EditorPane) which occupies all of the sapce of JInternalFrame and My maintoolbar also has a button to add the new JTextPane(name headPane) to the JInternalFrame Form at runtime. In the Editor class which extends JInternalFrame class , I am using the following code to add the JTextPane (at initial stage):

JTextPane HeadPane, EditorPane;
GroupLayout layout;
GroupLayout.SequentialGroup hseqgroup;
GroupLayout.SequentialGroup vseqgroup;

Editor() // Constructor of my JInternalFrame class
{
setOpaque(true);
setPreferredSize(new java.awt.Dimension(800, 600));
EditorPane = new javax.swing.JTextPane();
EditorPane.setOpaque(true);
EditorPane.setMaximumSize(new Dimension(2147483647,2147483647));
EditorPane.setMinimumSize(new Dimension(6,21));
EditorPane.setPreferredSize(new Dimension(6,21));

layout = new javax.swing.GroupLayout(getContentPane());
getContentPane().setLayout(layout);

hseqgroup = layout.createSequentialGroup();
vseqgroup = layout.createSequentialGroup();
GroupLayout.ParallelGroup hParallelGroup1 = layout.createParallelGroup
(GroupLayout.Alignment.LEADING);
hParallelGroup1.addComponent(EditorPane, javax.swing.GroupLayout.DEFAULT_SIZE, 790,
Short.MAX_VALUE);

hseqgroup.addGroup(hParallelGroup1);

GroupLayout.ParallelGroup vparallelGroup1 = layout.createParallelGroup(GroupLayout.Alignment.LEADING);
vparallelGroup1.addComponent(EditorPane, javax.swing.GroupLayout.Alignment.TRAILING,
540, javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE);

vseqgroup.addGroup(vparallelGroup1);
layout.setHorizontalGroup(hseqgroup);
layout.setVerticalGroup(vseqgroup);
pack();
this.closable = true;
this.maximizable = true;
}

and in the addNewJTextPane Button, I am using the following code:

HeadPane = new JTextPane();
HeadPane.setBounds(0, 0, EditorPane.getWidth(), 100);

HeadPane.setOpaque(true);
HeadPane.setMaximumSize(new Dimension(2147483647,100));
HeadPane.setMinimumSize(EditorPane.getMinimumSize());
HeadPane.setPreferredSize(EditorPane.getPreferredSize());

GroupLayout.ParallelGroup hparallelGroup1 = layout.createParallelGroup
(GroupLayout.Alignment.LEADING);
hparallelGroup1.addComponent(HeadPane, GroupLayout.DEFAULT_SIZE, 790, Short.MAX_VALUE);

hseqgroup.addGroup(hparallelGroup1);

GroupLayout.ParallelGroup vparallelGroup1 = layout.createParallelGroup (GroupLayout.Alignment.LEADING);
vparallelGroup1.addComponent(HeadPane, javax.swing.GroupLayout.Alignment.TRAILING, javax.swing.GroupLayout.PREFERRED_SIZE, 102, javax.swing.GroupLayout.PREFERRED_SIZE);

vseqgroup.addGroup(vparallelGroup1);

this.EditorPane.setLocation(0, 120);

When the user clicked on the button to add the new JTextPane, it adds the New JTextPane to the JInternal Form But change the size of the previous JTextPane and also the new JTextPane size and location not correct.

The form is appearing like it has devided into two columns and the first column displays the previous JTextPane and the second column displays the new JTextPane starting from the last of the First JTextPane.

I want to add the New JtextPane to the top of the previous JTextPane and also both JTextPane should occupy the complete horizontal area of the form. Only their vertical size should be differ and they should also resize when the form resize. Also I want to fix the vertical size of the new JTextPane not of the previous JTextPane.

How can I do it?
