更改我的java应用程序的图标 [英] Changing the icon of my java application

问题描述

对于简单的Java桌面应用程序我添加了一个带有NetBeans IDE助手的JFrame表单。对于此框架，我想更改标题栏中的图标。
我尝试在生成的View类中的构造函数的最后使用以下代码执行此操作：

for a simple Java Desktop Application I added a JFrame Form with the assistant of the NetBeans IDE. For this frame I want to change the icon in the title bar. I tried to do so with the following code at the very end of the constructor in the generated View class:

ImageIcon ii = new ImageIcon(iconUrl);
    this.getFrame().setIconImage(ii.getImage());

String iconUrl绝对正确，对象ii似乎没问题，据我所知调试器透视图中的变量概述。
但是，标题栏中的图标不会改变，它仍然是默认的java图标。

The String iconUrl is definitely correct, the object ii seems to be alright as far as I can judge from the variables overview in the debugger perspective. However, the icon in the title bar does not change, it's still the default java icon.

为什么？

推荐答案

你可以试试这个：

Image i = ImageIO.read(getClass().getResource("/path/to/image"));
setIconImage(i);

请注意，这里 / 代表你的 src 目录

Note that here / would represent your src directory
