Java JSplitPane

JSplitPane用于划分两个组件。这两个组件根据外观和实现方式进行划分, 用户可以调整它们的大小。如果两个组件的最小大小大于拆分窗格的大小, 则分隔符将不允许你调整其大小。

拆分窗格中的两个组件可以使用JSplitPane.HORIZONTAL_SPLIT从左到右对齐, 或者使用JSplitPane.VERTICAL_SPLIT从上到下对齐。当用户调整组件的大小时, 将使用组件的最小大小来确定可以设置组件的最大/最小位置。

JSplitPane示例

import java.awt.FlowLayout;
import java.awt.Panel;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JSplitPane;
public class JSplitPaneExample {
	private static void createAndShow() {
		// Create and set up the window.
		final JFrame frame = new JFrame("JSplitPane Example");
		// Display the window.
		frame.setSize(300, 300);
		frame.setVisible(true);
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		// set flow layout for the frame
		frame.getContentPane().setLayout(new FlowLayout());
		String[] option1 = { "A", "B", "C", "D", "E" };
		JComboBox box1 = new JComboBox(option1);
		String[] option2 = {"1", "2", "3", "4", "5"};
		JComboBox box2 = new JComboBox(option2);
		Panel panel1 = new Panel();
		panel1.add(box1);
		Panel panel2 = new Panel();
		panel2.add(box2);
		JSplitPane splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, panel1, panel2);
		// JSplitPane splitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT, // panel1, panel2);
		frame.getContentPane().add(splitPane);
	}
	public static void main(String[] args) {
		// Schedule a job for the event-dispatching thread:
		// creating and showing this application's GUI.
		javax.swing.SwingUtilities.invokeLater(new Runnable() {
			public void run() {
				createAndShow();
			}
		});
	}
