What I am trying to do is make it so the JTextPane takes up

  • 0

What I am trying to do is make it so the JTextPane takes up as much space as possible in the JPanel.
For my UpdateInfoPanel I am using:

public class UpdateInfoPanel extends JPanel {
private static final long serialVersionUID = 257125249175323679L;

private JTextPane textPane;

public UpdateInfoPanel(){
    textPane = new JTextPane();
    textPane.setBackground(Color.DARK_GRAY);
    textPane.setEditable(false);
    textPane.setMargin(null);
    textPane.setContentType("text/html");
    textPane.setText("<html><body style=\"font: Arial; color: white; padding: 5px; padding-top: 0;\"><h1 style=\"padding-top: 0;\">News</h1></body></html>");
    JScrollPane scrollPane = new JScrollPane(textPane);
    add(scrollPane);
    setBackground(Color.DARK_GRAY);
    textPane.setBorder(BorderFactory.createLineBorder(Color.BLACK));
}
}

And for my frame I simply create an instance of this and put it in BorderLayout.CENTER.
Currently this is how it looks. White border is the scroll pane, black is the textpane. What I want to do is have the borders be at the edge of the panel.

    Are you setting layout of your panel?

        setLayout(new BorderLayout());
    add(scrollPane,BorderLayout.CENTER);

    If you dont need the border of textpane do textPane.setBorder(null);
    Dont extend the JPanel. You can create is as you create the JTextPane.
