标签: rowheader

是否可以将文本添加到RowHeader的ColumnHeader中.我把自动增量放入我的DataGridView的Rowheaders中,我想把"不" 在那上面.

就像是:

//Autoincrement RowHeaders
foreach (DataGridViewRow row in myDGV.Rows)
{
    row.HeaderCell.Value = String.Format("{0}", row.Index + 1);
}

No. | myColumn 1 | myColumn 2

1   | myText     | myText
2   | myText     | myText

//the "No." column are actually RowHeaders

我试图编写java代码来弹出文本区域,如果我在右边的jtextarea中添加9000行,它会显示9000行和垂直行.

无论如何我能做到吗？

无论如何,我可以像在图片中添加行号.

请帮我!!谢谢!!

这是我的代码:

import java.awt.BorderLayout;
import java.awt.FlowLayout;
import java.awt.Font;
import java.awt.LayoutManager;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.BoxLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.ScrollPaneConstants;
import javax.swing.text.DefaultCaret;


public class test {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub


        final JFrame frame = new JFrame("Test");
        JPanel panel = new JPanel();
        panel.setLayout((LayoutManager) new BoxLayout(panel, BoxLayout.Y_AXIS));
        panel.setOpaque(true);
        final JTextArea textArea = new JTextArea(20, 30);
        textArea.setWrapStyleWord(true);
        textArea.setEditable(true);
        textArea.setFont(Font.getFont(Font.SANS_SERIF));
        JScrollPane …

我在自定义JTable的行标题中添加行有一些问题.

我用这段代码创建了这个JTable:

import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.Panel;
import java.awt.Toolkit;
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.StringSelection;
import java.util.ArrayList;
import java.util.List;

import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollBar;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.ScrollPaneConstants;
import javax.swing.border.BevelBorder;
import javax.swing.table.DefaultTableModel;
import javax.swing.table.TableColumnModel;


public class Form {

    public static void main(String[] args) {
        JFrame frame = new JFrame();

        List<String> visibleColumns = new ArrayList<String>();

        // THIS COLUMN NEED TO BE IN 2 LINES
        visibleColumns.add("Cod Type\nGroup");
        visibleColumns.add("Name");

        DefaultTableModel tableModel = new DefaultTableModel(visibleColumns.toArray(),5);
        JTable table = new JTable(tableModel); …
