移动jButton时遇到问题

Question

我正试图在NetBeans中使用Matisse来创建一个简单的游戏。。。比如Myst。我只想让它显示一个框架，它在右边有一个文本字段和按钮/清单。我能做到。然后我创建了一个Jpanel，显示在Frame上。我已经输入了一些图片，并创建了一套卡片，以便在需要时显示和不显示。每个卡片/场景都需要有针对每个场景不同的按钮。基本上，我想让用户按下透明的按钮来做事情（即移动到下一张图片/场景，找到一个键，等等）。我可以在每张图片中创建不同的按钮，但我似乎无法将它们移动到任何地方。我怀疑是因为马蒂斯，但我不知道。

以下是一些代码，我相信它很粗糙，因为这是我第一次用Java实现任何东西。在要显示的场景的最底部，我添加了一个按钮，它将显示。我现在几乎知道，由于位置的工作方式，setBounds不会工作。。。我该怎么把它放在什么地方呢。现在它只显示在图片的中上角。

场景框架：

Answer 1

您需要添加JFrame.frame.setLayout（null），以便在框架上调整字段（按钮、文本字段）。我也遇到了类似的问题

Answer 2

我发现一定是layoutManager混淆了什么。如果我设置：this.setLayout(null);，我就可以设置按钮的边界，它会显示我想要的位置和方式。如果这个问题没有足够的信息，我很抱歉，但我比我告诉你的还不了解自己。如果有人对我的所作所为有任何补充，我很乐意选择这一点作为我的答案。
