| Hello, people!
I have been using freeglut for a while, and there are three functions I really miss in FLTK's glut "emulation":
glutKeyboardUpFunc, glutSpecialUpFunc and glutLeaveMainLoop
The "up" functions are very nice for keeping an array of what keys are pressed when the mouse is moved. I.e.:
void keyup( unsigned char key, int x, int y)
{
if (key < NUM_KEYS)
w.keydown[key] = 0;
}
and then at mousemove one can do a check, and if the user is pressing "m" the object would be moved, etc.
I suppose this can be done in other ways with FLTK, but I think the freeglut team came up with a couple of good ideas I'd be happy to see in FLTK.
I tried to make my own key-up callback function, and calling it from the handle:
int UI::handle() {
switch (Fl::event()) {
case FL_KEYUP:
//printf("You released: %c\n", Fl::event_key());
callMyKeyboardUpFunc(Fl::event_key(), 0, 0); //TODO: FIX, TEST!!
break;
But for some reason, the handle function is not receiving any events since I added my glut code.
I'm using version 1.1.10 but I checked glut.h in ver 1.3-current as well, and the functions I am longing for are absent there too.
Thanks for a great library! | |

| The devs will chime in here on the addition of the three glut functions.
Meanwhile, let's take your separate question regarding the use of
handle() over to the fltk.general newsgroup/forum, to prevent noise
in our bug report system.
I've opened a thread on fltk.general for you entitled
"glut + handle() (Re: STR#2482)" with a possible answer. | |
