這篇文章給大家分享的是有關(guān)java如何實現(xiàn)桌面右下角彈窗效果的內(nèi)容。小編覺得挺實用的,因此分享給大家做個參考,一起跟隨小編過來看看吧。
最近需要一個java實現(xiàn)桌面彈窗的小功能,類似于電腦桌面右下角的小廣告一樣的功能,在csdn上找到一個很好的一個,功能很多,我去除了一點不需要的代碼,改了下外觀等。
修改后的代碼如下:
InfoUtil.java

private JLabel title = null; // 欄目名稱 private JLabel head = null; // 藍色標(biāo)題 private JLabel close = null; // 關(guān)閉按鈕 private JTextArea feature = null; // 內(nèi)容 private JScrollPane jfeaPan = null;

// 設(shè)置提示框的邊框,寬度和顏色 tw.getRootPane().setBorder( BorderFactory.createMatteBorder(1, 1, 1, 1, Color.white)); title.setPreferredSize(new Dimension(260, 26)); title.setVerticalTextPosition(JLabel.CENTER); title.setHorizontalTextPosition(JLabel.CENTER); title.setFont(new Font("宋體", Font.PLAIN, 12)); title.setForeground(Color.black); close.setFont(new Font("Arial", Font.BOLD, 15)); close.setPreferredSize(new Dimension(20, 20)); close.setVerticalTextPosition(JLabel.CENTER); close.setHorizontalTextPosition(JLabel.CENTER); close.setCursor(new Cursor(12)); close.setToolTipText("關(guān)閉"); head.setPreferredSize(new Dimension(250, 35));

this.word = word; // time = sdf.format(new Date()); init(); handle(); tw.setAlwaysOnTop(true); tw.setUndecorated(true); tw.setResizable(false); tw.setVisible(true); tw.run(); } public void close() { tw.close(); } } class TipWindow extends JDialog { private static final long serialVersionUID = 8541659783234673950L; private static Dimension dim; private int x, y; private int width, height; private static Insets screenInsets;

x = (int) (dim.getWidth() - width - 3); y = (int) (dim.getHeight() - screenInsets.bottom - 3); initComponents(); } public void run() { for (int i = 0; i <= height; i += 10) { try { this.setLocation(x, y - i); Thread.sleep(50); } catch (InterruptedException ex) { } } // 此處代碼用來實現(xiàn)讓消息提示框6秒后自動消失 try { Thread.sleep(6000); } catch (InterruptedException e) { e.printStackTrace(); } close(); } private void initComponents() { this.setSize(width, height);

i += 10) { try { setLocation(x, y + i); Thread.sleep(50); } catch (InterruptedException ex) { } } dispose(); } }
main.java
public class main { private final static String TITLE="彈窗"; public static void main(String[] args) { InfoUtil test = new InfoUtil(); test.show(TITLE, "這是一個彈窗測試!"); } }
效果如下:
