任何想法为什么scala中的swing组件似乎没有被完全包裹？例如，“paintImmediately”函数。或“更新”（因此我似乎无法覆盖）。
与 scala API 相比，对 Scala 源代码的检查似乎有点令人困惑..（scala 2.9 源代码如下所示）。API 似乎暗示存在这些其他功能：
http://www.scala-lang.org/api/current/scala/swing/Component $SuperMixin.html
据我所知，SuperMixin 特征是打开对等组件的覆盖调用的原因。只有一些似乎已定义。我如何覆盖更新（图形 g）？有没有更流畅的调用 Panel.peer.paintImmediately(rect) 的方式？
我正在考虑修改 Scala 源代码以构建一个新的 Panel 类来纠正这些绘图问题。
抽象类组件扩展 UIElement { 覆盖惰性 val peer: javax.swing.JComponent = new javax.swing.JComponent with SuperMixin {} var initP: JComponent = null
/**
* This trait is used to redirect certain calls from the peer to the wrapper
* and back. Useful to expose methods that can be customized by overriding.
*/
protected trait SuperMixin extends JComponent {
override def paintComponent(g: Graphics) {
Component.this.paintComponent(g.asInstanceOf[Graphics2D])
}
def __super__paintComponent(g: Graphics) {
super.paintComponent(g)

Component.this.paintBorder(g.asInstanceOf[Graphics2D])

def __super__paintBorder(g: Graphics) {
super.paintBorder(g)
}
override def paintChildren(g: Graphics) {
Component.this.paintChildren(g.asInstanceOf[Graphics2D])
}
def __super__paintChildren(g: Graphics) {
super.paintChildren(g)
}
override def paint(g: Graphics) {
Component.this.paint(g.asInstanceOf[Graphics2D])
}
def __super__paint(g: Graphics) {
super.paint(g)
}
}
