How do I typehint away this reflection warning?

2018-06-15 07:52:10

(set! *warn-on-reflection* true)
(proxy [javax.swing.JPanel] []
  (paintComponent [#^java.awt.Graphics g]
    (proxy-super paintComponent g)
    (.fillRect g 100 100 10 10)))

“反射警告，调用paintComponent无法解析”

因为代理超级使用隐含this 。

(let [^javax.swing.JPanel this this]
  (proxy-super paintComponent g))

It looks like the warning is for the line

(proxy-super paintComponent g)

Does the parent class of javax.swing.JPanel have a paintComponent method?

Removing that line works for me.
