Hi, I've stumbled across something which looks like a bug to me in the library_glut.js input code, but it could also be a misunderstanding on my side resulting from the many GLUT versions floating around (GLUT, FreeGlut, OpenGlut, ...):
In this commit the backspace and delete keys had been added as special keys: https://github.com/prenaux/emscripten/commit/c4b07c9d429603e492657992f77ad982577d72d9 The delete key returns the special key code 111 (0x6F) and 120 (0x78). But there are missing GLUT_KEY_xxx definitions for these in GL/freeglut_std.h , now the "official" GLUT doc states that these keys are not returned as special keys, but as ASCII code in the normal keyboard callback function: http://www.opengl.org/documentation/specs/glut/spec3/node54.html at the end it states: "Note that the escape, backspace, and delete keys are generated as an ASCII character." The latest freeglut_ext.h (downloaded from here: http://sourceforge.net/projects/freeglut/) has one definition for the delete key at 0x6F, but none for 0x78 (which would be backspace): #define GLUT_KEY_DELETE 0x006F So long story short: 1) it looks like GLUT and FreeGLUT don't agree on how to handle the Delete key :/ 2) the Delete key in FreeGLUT is only defined in the freeglut_ext.h header which we don't ship with 3) FreeGLUT doesn't define a special key code for Backspace anywhere, but library_glut.js returns it as a special key code I see 2 possible solutions: 1) go with the GLUT standard, remove Delete and Backspace as special keys, and return them as ASCII code (I would prefer this solution, but it breaks prenaux' change) 2) add the 2 more GLUT_KEY definitions to freeglut_std.h, GLUT_KEY_DELETE (normally defined in freeglut_ext.h, but we can't include this because 99% of the stuff in there isn't implemented in library_glut.js), and GLUT_KEY_BACKSPACE, which would be totally non-standard (neither GLUT nor FreeGLUT). Advice? :) -Floh -- You received this message because you are subscribed to the Google Groups "emscripten-discuss" group.
