Java 如何将JPanel放入JTabbedPane大小?
我正在尝试将一个Java 如何将JPanel放入JTabbedPane大小?,java,swing,jpanel,Java,Swing,Jpanel,我正在尝试将一个JPanel添加到另一个中,并使其适合父级的`JPanel大小 我有一个JPanel,其中包含一个JTable和一个JButton使用此代码: JScrollPane attributeTable = new JScrollPane(this); JPanel attributesPanel = new JPanel(); JPanel textFieldPanel=new JPanel(); JPanel buttonsPanel = new JPanel(); JBut
JPanel
添加到另一个中,并使其适合父级的`JPanel大小
我有一个JPanel
,其中包含一个JTable
和一个JButton
使用此代码:
JScrollPane attributeTable = new JScrollPane(this);
JPanel attributesPanel = new JPanel();
JPanel textFieldPanel=new JPanel();
JPanel buttonsPanel = new JPanel();
JButton newAttributeButton = new JButton("New Attribute");
attributesPanel.add(textFieldPanel, BorderLayout.CENTER);
attributesPanel.add(buttonsPanel, BorderLayout.SOUTH);
newAttributeButton.addActionListener(AttributesTableController.getInstance());
GroupLayout layout = new GroupLayout(textFieldPanel);
textFieldPanel.setLayout(layout);
// Turn on automatically adding gaps between components
layout.setAutoCreateGaps(true);
// Turn on automatically creating gaps between components that touch
// the edge of the container and the container.
layout.setAutoCreateContainerGaps(true);
// Create a sequential group for the horizontal axis.
GroupLayout.SequentialGroup hGroup = layout.createSequentialGroup();
// The sequential group in turn contains two parallel groups.
// One parallel group contains the labels, the other the text fields.
// Putting the labels in a parallel group along the horizontal axis
// positions them at the same x location.
//
// Variable indentation is used to reinforce the level of grouping.
hGroup.addGroup(layout.createParallelGroup().
addComponent(attributeTable).addComponent(newAttributeButton));
layout.setHorizontalGroup(hGroup);
// Create a sequential group for the vertical axis.
GroupLayout.SequentialGroup vGroup = layout.createSequentialGroup();
vGroup.addGroup(layout.createParallelGroup(Alignment.BASELINE).addComponent(attributeTable));
vGroup.addGroup(layout.createParallelGroup(Alignment.CENTER).
addComponent(newAttributeButton));
layout.setVerticalGroup(vGroup);
当我将这个面板(名为attributesPanel
)放入JTabbedPane
的选项卡中时,它只显示JTable
和JButton
,但位于面板的中心。我希望attributesPanel
的维度与打开的选项卡的维度相同
这是我用来将JPanel添加到JTabbedPane中的代码:
TabbedPane tabbedPane = new TabbedPane();
tabbedPane.setComponentAt(1, attributesPanel);
我尝试使用GridLayout
,它非常适合JPanel
,但我无法调整按钮的大小。我试过使用FlowLayout
和gridbagloayout
,但我无法正确显示它们,因为我遇到了同样的问题
提前感谢您。您的示例不完整,很难判断错误,但这可能会有帮助:
JTable table = new JTable (12, 5);
JButton button = new JButton ("Button");
JPanel panel = new JPanel ();
panel.setLayout (new BorderLayout ());
panel.add (table, BorderLayout.CENTER);
panel.add (button, BorderLayout.SOUTH);
JTabbedPane tabbedPane = new JTabbedPane ();
tabbedPane.addTab ("Tab", panel);
JFrame frame = new JFrame ();
frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
frame.getContentPane ().setLayout (new BorderLayout ());
frame.getContentPane ().add (tabbedPane, BorderLayout.CENTER);
frame.pack ();
frame.setVisible (true);
