Java-Eclipse插件-用表填充树项

问题描述

我有2个Java Bean类-公司和雇员。 Employee.java具有属性“名称”（String），“电子邮件”（String）和“工资”（int），以及所有属性的获取器和设置器。 Company.java具有属性“名称”（字符串），“城市”（字符串）和“雇员”（列表），获取器和设置器。 我想创建一个包含公司列表的TreeTable，对于每个公司，我想将一个包含公司雇员列表的表显示为TreeItem。对于此实现，我使用的是org.eclipse.swt.widgets中的类。 这是我的TreeTable代码：

public class CompaniesTableCreation {

private static List<Company> companies;

public static void main(String[] args) {
    init();
    Display display = new Display();
    final Shell shell = new Shell(display);
    shell.setLayout(new FillLayout());
    Tree companiesTree = new Tree(shell,SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL);
    companiesTree.setHeaderVisible(true);
    TreeColumn column1 = new TreeColumn(companiesTree,SWT.LEFT);
    column1.setText("Name");
    column1.setWidth(200);
    TreeColumn column2 = new TreeColumn(companiesTree,SWT.LEFT);
    column2.setText("City");
    column2.setWidth(200);
    for (Company c : companies) {
        TreeItem companyTreeItem = new TreeItem(companiesTree,SWT.NONE);
        companyTreeItem.setText(new String[] { c.getName(),c.getCity() });
        
        Table employeesTable = new Table(companiesTree,SWT.BORDER
                | SWT.V_SCROLL | SWT.H_SCROLL);
        employeesTable.setHeaderVisible(true);
        String[] titles = { "Name","Email address","Salary" };

        for (String title : titles) {
            TableColumn column = new TableColumn(employeesTable,SWT.NULL);
            column.setText(title);
        }

        for (Employee e : c.getEmployees()) {
            TableItem employeeTableItem = new TableItem(employeesTable,SWT.NULL);
            employeeTableItem.setText(0,e.getName());
            employeeTableItem.setText(1,e.getEmail());
            employeeTableItem.setText(2,String.valueOf(e.getSalary()));
        }

        for (int loopIndex = 0; loopIndex < titles.length; loopIndex++) {
            employeesTable.getColumn(loopIndex).pack();
        }
        
        TreeItem employeesItem = new TreeItem(companyTreeItem,SWT.NONE);
        employeesItem.setData(employeesTable);          

        //  If I display the employees as simple TableItems,data is OK,but I need a Table
        /*for (Employee e : c.getEmployees()) {
            TreeItem employeeItem = new TreeItem(treeItem,SWT.NONE);
            employeeItem.setText(new String[] { e.getName(),e.getEmail(),String.valueOf(e.getSalary()) });

        }*/
    }
    shell.pack();
    shell.open();
    while (!shell.isDisposed()) {
      if (!display.readAndDispatch()) {
        display.sleep();
      }
    }
    display.dispose();
  }

private static void init()
{
    companies = new ArrayList<Company>();
    Company c = new Company("IBM","New York");
    c.addEmployee(new Employee("John","john.ibm.com",100));
    c.addEmployee(new Employee("Michael","michael.ibm.com",200));
    companies.add(c);
    
    c = new Company("Google","San Francicsco");
    c.addEmployee(new Employee("Linda","linda.google.com",100));
    c.addEmployee(new Employee("Harry","harry.google.com",150));
    c.addEmployee(new Employee("Tom","tom.google.com",120));
    companies.add(c);
}
}

预期的结果是，当我从树中扩展公司时，打开分配有该公司员工的表，但是在当前实现中，什么都没有发生。
