java将文本框的标签放在框的上方,而不是侧面
如标题所述,我需要将文本框的标签移到文本框上方,而不是移到侧面。附件我有一张我的意思的照片what i havevswhat i want我试过搜索它,但我似乎找不到我要找的答案/不确定要查找什么。我尝试过使用JFrame,但它提供了一个单独的窗口,除非我需要将整个GUI设置为JFrame,以获得我想要的结果
actionPerformed方法也有一些东西,但与问题无关,但仍然正确显示

为了实现这一点,可以将嵌套的
JPanel
与其他布局一起使用。在这里,我同意BorderLayout
。您还可以选择其他允许垂直方向的布局。访问the visual guide to Layout Managers将帮助您发现它们
