How to make JTextArea blocks with height relative to content length, but with constant width?












0















I am trying to put JLabel and JTextArea into JPanel. There are few requirements for this JTextArea:
1. JTextArea must have constant width (approximately 680px).
2. Height must be relative to content. Content can be different.



    JPanel compilationErrorInfoPanel = new JPanel();
compilationErrorInfoPanel.setBackground(this.getBackground().darker());
compilationErrorInfoPanel.setBorder(BorderFactory.createMatteBorder(10, 10, 10, 10, this.getBackground()));

JTextArea jTextArea = new JTextArea(errorInfo);

jTextArea.setEditable(false);
jTextArea.setLineWrap(true);
jTextArea.setWrapStyleWord(true);

jTextArea.setBackground(compilationErrorInfoPanel.getBackground());
jTextArea.setFont(new Font(Font.SANS_SERIF, Font.PLAIN, 14));
jTextArea.setBorder(BorderFactory.createMatteBorder(10, 10, 10, 10, jTextArea.getBackground()));
FontMetrics metrics = getFontMetrics(jTextArea.getFont());
int columnWidth = metrics.charWidth('m');
jTextArea.setColumns(680/columnWidth);
JLabel errorLabel = new JLabel(new ImageIcon(getClass().getResource(Configuration.getProperties().getString("jresource.icon"))));
compilationErrorInfoPanel.add(errorLabel);
compilationErrorInfoPanel.add(jTextArea);

compilationErrorInfoPanel.setPreferredSize(compilationErrorInfoPanel.getPreferredSize());
compilationErrorInfoPanel.setMaximumSize(compilationErrorInfoPanel.getPreferredSize());
compilationErrorInfoPanel.setMinimumSize(compilationErrorInfoPanel.getPreferredSize());


The problem i faced:
if any content line longer than area width, JTextArea will creep out of JPanel.
I am using BoxLayout.
Is their any solution?

  • Have you tried to set a maximum size for the JTextArea? It should honor that value.

  • JTextArea will creep out of JPanel. Is their any solution? - This could be because of the layout manager used. The FlowLayout which will display all components in a single row. If there is no space for the component it will wrap to the next row, which may cause the component to be hidden. Post a proper Minimal, Complete, and Verifiable example that demonstrates the problem.

Solved with checking real lines amount.



      String lines = content.split("n");
int linesCount = 0;
for (int i = 0; i < lines.length; i++) {
linesCount++;
linesCount += metrics.stringWidth(lines[i]) / (jTextArea.getColumns() * columnWidth);
}
jTextArea.setRows(linesCount);
