如何使JTable填充整个可用空间? [英] How to make a JTable fill entire available space?

问题描述

我想创建一个带有表的面板，该表填充整个可用空间.

I want to created a panel with a table, which fills the entire available space.

我使用以下代码执行此操作:

I do this using following code:

public class MyFrame extends JFrame {
    public EconomyFrame() throws HeadlessException {
        super("...");

        final JTabbedPane tabbedPane = new JTabbedPane();

        add(tabbedPane);

        final JPanel companiesPanel = new JPanel();

        final CompaniesTableModel companiesModel = new CompaniesTableModel
                (ApplicationStateSingleton.INSTANCE.getPersistence().getCompanies());

        final JTable companiesTable = new JTable(companiesModel);

        ApplicationStateSingleton.INSTANCE.getEventBus().subscribeToPropertyChanges(companiesModel);

        companiesPanel.add(new JScrollPane(companiesTable));

        tabbedPane.addTab("Companies", companiesPanel);
    }
}

但是它不起作用，因为当我调整框架大小时，表格仅填充了可用空间的一部分(请参见下面的屏幕截图).

But it doesn't work because when I resize the frame, the table fills only part of the available space (see screenshots below).

我该如何解决(使表格填满整个可用空间)?

How can I fix (make the table fill the entire available space) ?

推荐答案

使用布局管理器，该管理器允许JTable占据整个可用区域，而不是JPanel使用的默认FlowLayout(仅使用其首选组件)尺寸

Use a layout manager that allows the JTable occupy the full area available rather than the default FlowLayout used by JPanel which only uses its components preferred sizes

JPanel companiesPanel = new JPanel(new GridLayout());
