如何使用 Java 在 JTable 中启用行选择
java 8object oriented programmingprogramming
要启用行选择，请使用 setRowSelectionAllowed () 方法并将其设置为 TRUE −
table.setCell setRowSelectionAllowed(true);
以下是在 JTable 中启用行选择的示例 −
示例
package my;
import java.awt.Color;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.border.TitledBorder;
public class SwingDemo {
public static void main(String[] args) {
JFrame frame = new JFrame();
JPanel panel = new JPanel();
panel.setBorder(BorderFactory.createTitledBorder(
BorderFactory.createEtchedBorder(), "ODI Rankings", TitledBorder.CENTER, TitledBorder.TOP));
String[][] rec = {
{ "1", "Steve", "AUS" },
{ "2", "Virat", "IND" },
{ "3", "Kane", "NZ" },
{ "4", "David", "AUS" },
{ "5", "Ben", "ENG" },
{ "6", "Eion", "ENG" },
};
String[] header = { "Rank", "Player", "Country" };
JTable table = new JTable(rec, header);
table.setShowHorizontalLines(true);
table.setGridColor(Color.orange);
table.setRowSelectionAllowed(true);
panel.add(new JScrollPane(table));
frame.add(panel);
frame.setSize(550, 400);
frame.setVisible(true);
}
}
输出如下。这里，我们选择了一行。由于上面的 setRowSelectionAllowed() 设置为 TRUE，我们现在可以选择一行了。 −
