如何在antlr4.5.1中显示解析器树的JDialog？

Question

I want the system to pop up a dialog to show the parser tree. I want to know if there is a function to invoke in Java so I can do the thing above and I know at version 4.3 antlr got a function in class RuleContext named inspect to pop up a JDialog.

Answer 1

I had the same problem when updating to the latest Antlr 4 version. The inspect method can now be found in the Trees class, as of this commit .
