如何选择一个标签,就像点击一个按钮一样? 我用Google搜索并查看了所有操作,但只有这么多... :(
有人知道吗?
提前致谢!

在按钮上添加一个动作侦听器,该按钮在JTabbedPane上调用setSelectedComponent或setSelectedIndex。

我不确定您对该按钮的意思,但您可能正在寻找setSelectedComponent
或setSelectedIndex
。

如果你的jtabbedpane的名字是mytabbedpane,它就像这样:
mytabbedpane.getSelectedIndex();
返回该选项卡的int(0,1 .. n)或
mytabbedpane.getSelectedComponent();
返回标签名称的字符串(“Firts标签”,“第二个标签”,......)。
如果你想对布尔逻辑使用“getSelectedComponent()”,你应该写一些类似的东西:
if (mytabbedpane.getSelectedComponent().equals("First tab")) {
//code here
}
和“getSelectedIndex()”当然是:
if (mytabbedpane.getSelectedIndex() == 0) {
//code here
}

试试这段代码:
tabbedPane.addTab(tabName, component);
int count = tabbedPane.getTabCount();
tabbedPane.setSelectedIndex(count-1);
