I used the code from the text based hunt the wumpus game discussed here: Text based game “Hunt the Wumpus” Version 3 to create a gui Version based on excercises from PPP by Stroustrup.
For the GUI i used FLTK because the book is based on it. I used it with MSVS2017. I got FLTK to run with this tutorial: https://bumpyroadtocode.com/2017/08/05/how-to-install-and-use-fltk-1-3-4-in-visual-studio-2017-complete-guide/
Also Stroustrup provides some basic GUI library which wraps the FLTK functions: http://www.stroustrup.com/Programming/PPP2code/
I modified the headers sligtly by removing the std_lib_facilities.h because it includes many unessary stuff and basically hides which c++ standard headers are included.
Unfortunately the source code is a bit to big to get posted here, espcially the wumpus_window.cpp file. I do some repetive stuff there which i think is the reason i have to much code.
Here is the class declaration for the Window and the Rooms:

What bothers me here the most is the handling of the Buttons. I have 4 Buttons for each Room:
-guess room has a bat (draws a small Rectangle in the room indicate there could be a bat)
-guess room has the wumpus
-guess room has a pit
-move -> pushing trys to move the player into the room.
I tryed to include these Buttons directly into the class Room but i could only manage to put in the coordinates and the sizes.
If i create the Buttons inside the room and assign a callback function from inside the Room class the application crashes because i violate that Wumpus_window and not Room is responsible for draw the widgets (the small rectangles get displayed/ hided in the callbacks).
So currently i have these 80 numbered callback methods in Wumpus_window. Which would be alot less repetive in the Room class. With this initing the buttons is a lot of repetive work which cant be looped (e.g. void init_btns_guess_pit())

Feel free to comment anything else you find suspicious to Wumpus_window.h or Wumpus_window.cpp. The other files are the support files from Stroustrup slightly modified.
