[英]Is it possible to make this type of jtabbedpane?
JTabbedPane不能真正做到这一点。 我认为可以破解TabbedPaneUI,但我认为这种方法不可靠。
相反,我只是将JToggleButtons放在GridLayout中。 它们看起来并不完全像选项卡,但它们将像标签一样有用,我怀疑用户会关心这两种方式。
标签下方的小“信息”区域和主要内容区域均应均为CardLayout。 这将确保每个文件都足够大以容纳所有可能的内容。
String title1 = "Tab 1";
String title2 = "Tab 2";
Component infoPanel1 = new FileInfoPanel();
Component infoPanel2 = new OtherInfoPanel();
Component content1 = new WaveFormPanel();
Component content2 = new OtherPanel();
final CardLayout infoLayout = new CardLayout();
final JComponent infoArea = new JPanel(infoLayout);
infoArea.add(infoPanel1, "1");
infoArea.add(infoPanel2, "2");
final CardLayout contentAreaLayout = new CardLayout();
final JComponent contentArea = new JPanel(contentAreaLayout);
contentArea.add(content1, "1");
contentArea.add(content2, "2");
class TabSwitcher
implements ActionListener {
private String cardID;
TabSwitcher(String cardID) {
this.cardID = cardID;
}
@Override
public void actionPerformed(ActionEvent event) {
infoLayout.show(infoArea, cardID);
contentAreaLayout.show(contentArea, cardID);
}
}
JToggleButton tab1 = new JToggleButton("Tab 1");
tab1.setHorizontalAlignment(SwingConstants.LEADING);
tab1.addActionListener(new TabSwitcher("1"));
JToggleButton tab2 = new JToggleButton("Tab 2");
tab2.setHorizontalAlignment(SwingConstants.LEADING);
tab2.addActionListener(new TabSwitcher("2"));
ButtonGroup group = new ButtonGroup();
group.add(tab1);
group.add(tab2);
JComponent tabsPanel = new JPanel(new GridLayout(0, 1));
tabsPanel.setBorder(BorderFactory.createEmptyBorder(6, 0, 12, 0));
tabsPanel.add(tab1);
tabsPanel.add(tab2);
JComponent tabArea = new JPanel(new BorderLayout());
tabArea.add(tabsPanel, BorderLayout.PAGE_START);
tabArea.add(infoArea, BorderLayout.CENTER);
JComponent analyser = new JPanel(new BorderLayout());
analyser.add(tabArea, BorderLayout.LINE_START);
analyser.add(contentArea, BorderLayout.CENTER);
tab1.doClick();
frame.getContentPane().add(analyser);
frame.pack();
