Question

我正在Java Swing中实现一个UI。因此我使用JTabbedPane。 tabbedPane在启动时没有组件。当我向tabbedpane添加一个标签时，tabbedpane的宽度会增加，当我删除标签时，宽度会调整到启动时的宽度。这不应该发生。

tabbedpane放置在JPanel上，它有一个网格布局。

布局代码：



Container contentPane = mainFrame.getContentPane();
contentPane.setLayout( new GridBagLayout() );
GridBagConstraints c = new GridBagConstraints();        
// add the component tree
initComponentTree();
c.gridx = 0;
c.gridy = 0;
c.gridheight = 1;
c.gridwidth = 1;
c.fill = GridBagConstraints.BOTH;
c.anchor = GridBagConstraints.LINE_START;
c.weightx = 1;
c.weighty = 1;
contentPane.add( componentTree, c );        
// add the tabbed pane
initTabbedPane();
c.gridx = 1;
c.weightx = 10;
contentPane.add( tabbedPane, c );       
// add the status panel
initStatusPanel();
c.gridx = 0;
c.gridy = 1;
c.gridwidth = 2;
c.fill = GridBagConstraints.HORIZONTAL;
c.anchor = GridBagConstraints.LINE_START;
c.weightx = 0;
c.weighty = 0;
contentPane.add( statusPanel, c );

Container contentPane = mainFrame.getContentPane(); contentPane.setLayout( new GridBagLayout() ); GridBagConstraints c = new GridBagConstraints(); // add the component tree initComponentTree(); c.gridx = 0; c.gridy = 0; c.gridheight = 1; c.gridwidth = 1; c.fill = GridBagConstraints.BOTH; c.anchor = GridBagConstraints.LINE_START; c.weightx = 1; c.weighty = 1; contentPane.add( componentTree, c ); // add the tabbed pane initTabbedPane(); c.gridx = 1; c.weightx = 10; contentPane.add( tabbedPane, c ); // add the status panel initStatusPanel(); c.gridx = 0; c.gridy = 1; c.gridwidth = 2; c.fill = GridBagConstraints.HORIZONTAL; c.anchor = GridBagConstraints.LINE_START; c.weightx = 0; c.weighty = 0; contentPane.add( statusPanel, c );

希望有人可以提供帮助！

Answer 1

尝试将ipadx的{{1}}值设置为所需的宽度。

Answer 2

我一直认为应该不惜一切代价避免使用GridBagLayout。它确实提供了通过嵌套面板与其他布局无法实现的任何功能。它提供的唯一的东西是很多挫折。

我建议使用BorderLayout将JTabbedPane放在面板中并将其置于CENTER位置。如果你坚持使用GridBayLayout，你可以尝试使用setMinimumSize（）方法，GridBagLayout是尊重该方法的布局管理器之一（BoxLayout是另一个）。

您是否尝试过setSize()？

JTabbedPane pane;
pane.setSize(SOME_WIDTH_CONSTANT, SOME_HEIGHT_CONSTANT);

将JTabbedPane宽度设置为常量
