我有应该显示一些信息的简单GUI。我创建了多个JTabbedPanes的菜单，并且选项卡按预期相互堆叠。我正在尝试删除每个选项卡的左侧，右侧和底部的边框，以使其看起来不会堆叠。我还没有找到能解决我问题的方法，实际上有办法吗？
谢谢您提前回答。

最佳答案
可能，但是很难。唯一的方法是为选项卡式窗格提供自己的UI。这是一个示例，它不能完全满足您的要求，但是可以显示您必须走的路（对不起，但是我不能提供完整的解决方案，因为它可能会花费很多时间）。
import java.awt.Graphics;
import java.awt.Insets;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTabbedPane;
import javax.swing.SwingUtilities;
import javax.swing.UIManager;
import javax.swing.WindowConstants;
import javax.swing.plaf.metal.MetalLookAndFeel;
import javax.swing.plaf.metal.MetalTabbedPaneUI;
public class BorderlessTabsExample implements Runnable {
public static void main(String[] args) {
try {
UIManager.setLookAndFeel(MetalLookAndFeel.class.getName());
} catch (Exception e) {
// Nothing
}
SwingUtilities.invokeLater(new BorderlessTabsExample());
}
@Override
public void run() {
JTabbedPane tabber = new JTabbedPane();
tabber.addTab("First", new JLabel("First"));
tabber.addTab("Second", new JLabel("Second"));
tabber.addTab("Third", new JLabel("Third"));
// set the UI which will paint your tabs
tabber.setUI(new MetalBorderlessTabbedPaneUI());
JFrame frm = new JFrame("Tabber test");
frm.add(tabber);
frm.setSize(500, 400);
frm.setLocationRelativeTo(null);
frm.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frm.setVisible(true);
}
private static class MetalBorderlessTabbedPaneUI extends MetalTabbedPaneUI {
@Override
protected void installDefaults() {
super.installDefaults();
if (contentBorderInsets != null) {
contentBorderInsets = new Insets(contentBorderInsets.top, 0, 0, 0);
}
}
@Override
protected void paintContentBorderRightEdge(Graphics g, int tabPlacement, int selectedIndex, int x, int y, int w, int h) {
// Do nothing
}
@Override
protected void paintContentBorderBottomEdge(Graphics g, int tabPlacement, int selectedIndex, int x, int y, int w, int h) {
// Do nothing
}
@Override
protected void paintContentBorderLeftEdge(Graphics g, int tabPlacement, int selectedIndex, int x, int y, int w, int h) {
// Do nothing
}
}
}
