在 JTable 中使用 Search Filter 和 mouseClicked Event 时出现的问题

Question

此代码提供了带有 SearchFilter 的员工详细信息 JTable。在 Employee Processing 和 Employee Processed Columns 上使用鼠标单击，它应该被定向到与当前行中的员工相关的 url。下面的代码工作正常，除非使用搜索过滤器。当我使用搜索过滤器并在过滤行上单击鼠标时，它会指向 JTable 第一行中与员工详细信息相关的 URL，而不是当前过滤行的员工详细信息。有人可以帮我解决这个问题吗？

Answer 1

int col = tab.getSelectedColumn();
int row = tab.getSelectedRow();

// Employee Processing columnindex is
if (EMPLOYEE_PROCESSING_COLUMN_INDEX == col) {
    String employeeName = (String) tab.getModel().getValueAt(row, col);

当您在 table 上使用 Sorter/Filter 时，数据不是来自 TableModel 的 sorted/removed。您只能看到数据的 sorted/filtered 视图。因此，您不再具有 "table row" 和 "model row".

的一对一映射

因此您需要使用 JTable:

的方法访问数据

    //String employeeName = (String) tab.getModel().getValueAt(row, col);
    String employeeName = (String) tab.getValueAt(row, col);

JTable 的 getValueAt(...) 方法将自动转换 row/column 索引以映射到 TableModel 中的适当数据，然后它将调用 getValueAt(...)方法TableModel给你。

阅读 JTable API 您会发现 4 个 convert???(...) 方法可以在模型和视图之间转换 row/column 索引，如果您需要进行这种转换手动。

您还需要修复您尝试从 TableModel 访问数据的其他地方。
