| This bug is present in version 1.1.2 and is also present in 2.0cvs.
Essentially boils down to:
glutGetModifiers() must return a bitwise OR of
GLUT_ACTIVE_SHIFT,
GLUT_ACTIVE_CTRL, and
GLUT_ACTIVE_ALT -- see the GLUT spec for more info.
The current implementation is:[see fltk/glut.h]
inline int glutGetModifiers() {return fltk::event_state();}
which returns a host of other flags in addition to the three
mentioned above.
The right implementation would be
------------8<--------------------------
// WARNING: these values are different than Glut uses:
enum {
GLUT_ACTIVE_SHIFT = fltk::SHIFT,
GLUT_ACTIVE_CTRL = fltk::CTRL,
GLUT_ACTIVE_ALT = fltk::ALT
};
inline int glutGetModifiers() { return fltk::event_state() & (GLUT_ACTIVE_SHIFT | GLUT_ACTIVE_CTRL | GLUT_ACTIVE_ALT) ;}
------------8<--------------------------
With this change, I'm happily using glut + Fltk in my
projects . Fltk rocks!
Not sure if assigned high priority is OK - it is a simple bug fix -
but took me some time to find! | |
