将JFrame插入Swing中的选项卡 [英] Insert JFrame into a Tab in Swing
问题描述
我有一个已经给定的JFrame frame
,我想将其显示(插入)到JTabbedPane
的tab
中,但这不可能明确地做到这一点:
I Have an already given JFrame frame
, that I want to show it (insert it) into a tab
of JTabbedPane
, but that was not possible explicitely like that:
frame = new JFrame();
frame.setBounds(100, 100, 450, 300);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
mainTabs.addTab("Editor", null, frame, null);
错误是:
java.lang.IllegalArgumentException: adding a window to a container
我尝试了一些解决方案,例如将框架插入到JPanel
中,但也没有用.我有将其转换为InternalJFrame
的想法,但是对此我一无所知.
I tried some solutions like to insert the frame into a JPanel
but also in vain. I have the idea to convert it into an InternalJFrame
but I don't have any idea about that.
是插入frame
的任何解决方案吗?
Is that any solution to insert that frame
?
更新:
我尝试过这种解决方案:
I tried that soluion:
mainTabs.addTab("Editor", null, frame.getContentPane(), null);
但是我丢失了我添加的JMenuBar
.
But i lost the JMenuBar
that I added.
推荐答案
您不能将JFrame
(或另一个顶级组件)添加到另一个组件/容器,但是可以使用getContentPane()
框架方法,获取框架的主面板并将其添加到JTabbedPane
选项卡.像下一个一样:
You can't add JFrame
(or another top-level component) to another component/container, but you can use getContentPane()
method of frame, to get main panel of your frame and add that to JTabbedPane
tab. Like next:
JTabbedPane tabs = new JTabbedPane();
JFrame frame = new JFrame();
frame.add(new JButton("button"));
tabs.addTab("1", frame.getContentPane());
此外,您可以将JFrame
更改为JPanel
并使用它.
Also you can change JFrame
to JPanel
and use that.
了解有关 JInternalFrame
,顶级容器.
getContentPane()
不返回任何装饰或JMenuBar
,您需要手动添加此组件,如下一个带有菜单的示例:
getContentPane()
doesn't return any decorations or JMenuBar
, this components you need to add manually, like in next example with menu:
JTabbedPane tabs = new JTabbedPane();
JFrame frame = new JFrame();
JMenuBar bar = new JMenuBar();
bar.add(new JMenu("menu"));
frame.setJMenuBar(bar);
frame.add(new JButton("button"));
JPanel tab1 = new JPanel(new BorderLayout());
tab1.add(frame.getJMenuBar(),BorderLayout.NORTH);
tab1.add(frame.getContentPane());
tabs.addTab("1", tab1);
