我的 JTable (jtblLot) 鼠标单击事件有时不会触发。主要是频繁点击

下面是鼠标点击事件的代码

 private void jtblLot_MouseClicked(java.awt.event.MouseEvent evt) {       

    int row = jtblLot.rowAtPoint(evt.getPoint()), currId = 0;
    int col = 3;

    lotId = jtblLot.getValueAt(row, col).toString();
    if (jtblLot.getValueAt(row, 1) != null) {
    sizeGrp_up = jtblLot.getValueAt(row, 1).toString();
    } else {
    sizeGrp_up = "0";
    }

    if (jtblLot.getValueAt(row, 4) != null) {
    if (jtblLot.getValueAt(row, 4).toString().compareTo("") !=0)
    {
    currId = Integer.parseInt(jtblLot.getValueAt(row, 4).toString()) - 1;
    }
    } else {
    sizeGrp_up = "0";
    }

    cmbCurrency.setSelectedIndex(currId);
    jlblLotId.setText(lotId);

    // Sets Model For Another JTable(jtblLGP) In My Form Get Data From DB
    getLotGradePriceData();

    //On Click I get The Focus To The Clicked Cell
    int col_ = jtblLot.columnAtPoint(evt.getPoint());
    jtblLot.setCellSelectionEnabled(true);
    jtblLot.changeSelection(row, col_, false, false);
    jtblLot.scrollRectToVisible(new Rectangle(jtblLot.getCellRect(row, col_, true)));

}

如果您需要处理每次点击,我建议您处理mouseReleased而不是mouseClicked.

  • 以这种方式更新 Swing GUI 不是一个好主意,你会阻塞 EDT,直到 JDBC 事件结束,

  • 使用Runnable#Thread(所有输出到 Swing GUI,必须将其 XxxModel 包装到invokeLater)或SwingWorker作为此作业的工人线程,

  • 使用ListSelectioListener作为最简单的方法

  • 也许还有一些其他问题,为了更好地帮助尽快发布SSCCE,简短,可运行,可编译,使用局部变量而不是 JDBC 事件
