I am designing a GUI for an image editor in which I have multiple buttons which apply different effects to the selected image. Currently I have the Display button in the top center of the window, the Load button in the bottom center of the window, and I want the effect buttons stacked on the left side of the window. Here is the image of my GUI, with the ButtonPanel JPanel in red, the FileChooser JPanel in green, and the ImageDisplay JPanel in blue:

如您所见，ButtonPanel中的按钮是水平堆叠而不是垂直堆叠.我希望它们垂直堆叠.谢谢您的帮助.

As you can see, the buttons in the ButtonPanel are stacking horizontally instead of vertically. I would like them to stack vertically. Thank you for the help.

推荐答案

ButtonPanel中的按钮是水平堆叠，而不是垂直堆叠.我希望它们垂直堆叠.

the buttons in the ButtonPanel are stacking horizontally instead of vertically. I would like them to stack vertically.

JPanel的默认布局是FlowLayout，它将水平显示所有组件.

The default layout for a JPanel is a FlowLayout which displays all components horizontally.

使用其他布局管理器.也许是GridLayout.如果正确设置了构造函数参数，则使用GridLayout可以垂直显示组件.

Use a different Layout Manager. Maybe a GridLayout. With a GridLayout you can display components vertically if you set the constructor parameters properly.

在布局管理器上，从Swing教程中阅读本节.有关更多信息和工作示例.

Read the section from the Swing tutorial on Layout Managers for more information and working examples.
