I want to know the cause of poor mouse response

Current status

When you release the key by implementing the long press judgment of the mouse The detection is not working properly. It is the code of the comment ///// part.
※The problem is the comment part of the Edit.cpp part.

Solution

  • The example is incomplete, but I don't see a check for KEY_MOUSE returned from getch. ncurses won't be ready to return useful information in getmouse until that happens.
