无论显示器分辨率如何，如何将 JFrame 设置为居中显示? [英] How to set JFrame to appear centered, regardless of monitor resolution?

问题描述

在使用 Java 时，我发现启动应用程序时很难将主窗口定位在屏幕中央.

While working with Java, I find it hard to position my main window in the center of the screen when I start the application.

有什么办法可以做到吗?它不必垂直居中，水平对齐对我来说是更重要的目标.但也欢迎垂直对齐.

Is there any way I can do that? It doesn't have to be vertically centered, horizontal alignment is the more important goal for me. But vertical alignment is also welcome.

推荐答案

我一直都是这样:

Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
this.setLocation(dim.width/2-this.getSize().width/2, dim.height/2-this.getSize().height/2);

其中 this 是所涉及的 JFrame.

where this is the JFrame involved.
