glutgetmodifiers(3)
NAME
glutGetModifiers - returns the modifier key state when
certain callbacks were generated.
SYNTAX
int glutGetModifiers(void);
DESCRIPTION
glutGetModifiers returns the modifier key state at the
time the input event for a keyboard, special, or mouse
callback is generated. This routine may only be called
while a keyboard, special, or mouse callback is being han
dled. The window system is permitted to intercept window
system defined modifier key strokes or mouse buttons, in
which case, no GLUT callback will be generated. This
interception will be independent of use of glutGetModi
fiers.
The bitmask components of the returned integer value are:
- GLUT_ACTIVE_SHIFT
- Set if the Shift modifier or Caps Lock is active.
- GLUT_ACTIVE_CTRL
- Set if the Ctrl modifier is active.
- GLUT_ACTIVE_ALT
- Set if the Alt modifier is active.
