我正在Windows 10上运行,一些细节:

  • 科特林版本:1.2.70
  • TornadoFX版本:1.7.17
  • jvm目标:1.8

在这里我将字体更改为我的应用程序:

override val root = hbox{
    menubar{
        menu("File"){
            item("Settings"){
                style {
                    font = loadFont("app/assets/font/Ubuntu-L.ttf", 6.0)!! 
                }
            }
        }
    }

}

调用loadFont()函数时引发错误。 这是堆栈跟踪:

经过一番搜索,我发现可以尝试在Windows上安装该字体,但是没有任何变化。
