如下图所示,Java文本是水平的。我想做的是让JTabbedPane标题垂直排列。
在谷歌上搜索时,我发现唯一的方法是添加额外的库。但我想知道是否可以在不添加任何额外库的情况下完成?
我希望标题1和标题2是垂直排列而不是水平的。
请看下图:

请看下图:
LabelUI
的JLabel
,它会得到我期望的结果:JTabbedPane tabPane = new JTabbedPane(JTabbedPane.LEFT);
// Add tabs with no text
tabPane.addTab(null, component1);
tabPane.addTab(null, component2);
// Create vertical labels to render tab titles
JLabel labTab1 = new JLabel("Tab #1");
labTab1.setUI(new VerticalLabelUI(false)); // true/false to make it upwards/downwards
tabPane.setTabComponentAt(0, labTab1); // For component1
JLabel labTab2 = new JLabel("Tab #2");
labTab2.setUI(new VerticalLabelUI(false));
tabPane.setTabComponentAt(1, labTab2); // For component2
您需要使用HTML语法来更改禁用的选项卡。
tabbedPane.addTab("<html>T<br>i<br>t<br>t<br>l<br>e<br>1</html>", panel1);

库,那么有一个名为WebVerticalLabel
的组件可以显示垂直文本。JTabbedPane .setTabComponentAt(1, new WebVerticalLabel("Title1"));
<html style="font-size:8px">
,但它没有起作用,它显示了整个 HTML 文本而不是标题。 - Adel Boutros
