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

使用Java时，我发现在启动应用程序时很难将主窗口放在屏幕中央。

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

我有什么方法可以去做？
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

我总是以这种方式做到：

I always did it in this way:

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

其中此是涉及的JFrame。

where this is the JFrame involved.
