设置图标在JLabel上出错

标签: java eclipse swing jlabel windowbuilder

我在尝试更改JLabel的图标时出现问题。我在eclipse中使用windowbuilder插件来制作这个程序,所以只要忽略标签上所有错误的命名选择,所有这些都将在以后更改。

我遇到的错误是在我的代码底部,我尝试更改label_1的图标,我收到以下消息。

  

jlabel类型中的方法seticon(icon)不适用于   arguments(string)

有谁知道这可能是什么?

这是我的代码。对不起,这是相当长的,我认为这是你的窗口构建器:

是的,因为根据找到的文档here,setIcon()接受一个I​​con作为参数而不是String。所以,你的代码应该是......

label_1.setIcon(new ImageIcon("C:\\Users\\Josh\\Desktop\\blank.png"));

我建议您将来使用文档。这真是一个非常好的做法。

答案 1 :(得分:0)

我认为错误信息对于出了什么问题是不言自明的。 “setIcon()”方法需要Icon类的实例而不是字符串实例。

jLabelObject.setIcon("string")    // Do not pass image path
