NAME
glutSpecialUpFunc - sets the special keyboard up (key release) callback for the current window. SYNTAX
#include <GLUT/glut.h> void glutSpecialUpFunc(void (*func)(int key, int x, int y)); ARGUMENTS
func The new special callback function. DESCRIPTION
glutSpecialUpFunc sets the special keyboard up (key release) callback for the current window. The special keyboard up callback is triggered when keyboard function or directional keys are released. The key callback parameter is a GLUT_KEY_* constant for the special key pressed. The x and y callback parameters indicate the mouse in window relative coordinates when the key was pressed. When a new window is created, no special up callback is initially registered and special key releases in the window are ignored. Passing NULL to glutSpecialUpFunc dis- ables the generation of special up callbacks. During a special up callback, glutGetModifiers may be called to determine the state of modifier keys when the key release generating the callback occurred. To avoid the reporting of key release/press pairs due to auto repeat, use glutIgnoreKeyRepeat to ignore auto repeated keystrokes. An implementation should do its best to provide ways to generate all the GLUT_KEY_* special keys. The available GLUT_KEY_* values are: GLUT_KEY_F1 F1 function key. GLUT_KEY_F2 F2 function key. GLUT_KEY_F3 F3 function key. GLUT_KEY_F4 F4 function key. GLUT_KEY_F5 F5 function key. GLUT_KEY_F6 F6 function key. GLUT_KEY_F7 F7 function key. GLUT_KEY_F8 F8 function key. GLUT_KEY_F9 F9 function key. GLUT_KEY_F10 F10 function key. GLUT_KEY_F11 F11 function key. GLUT_KEY_F12 F12 function key. GLUT_KEY_LEFT Left directional key. GLUT_KEY_UP Up directional key. GLUT_KEY_RIGHT Right directional key. GLUT_KEY_DOWN Down directional key. GLUT_KEY_PAGE_UP Page up directional key. GLUT_KEY_PAGE_DOWN Page down directional key. GLUT_KEY_HOME Home directional key. GLUT_KEY_END End directional key. GLUT_KEY_INSERT Inset directional key. Note that the escape, backspace, and delete keys are generated as an ASCII character. SEE ALSO

NAME
glutKeyboardUpFunc - sets the keyboard up (key release) callback for the current window. SYNTAX
void glutKeyboardUpFunc(void (*func)(unsigned char key, int x, int y)); ARGUMENTS
func The new keyboard up callback function. DESCRIPTION
glutKeyboardFunc sets the keyboard up (key release) callback for the current window. When a user types into the window, each key release matching an ASCII character will generate a keyboard up callback. The key callback parameter is the generated ASCII character. The state of modifier keys such as Shift cannot be determined directly; their only effect will be on the returned ASCII data. The x and y callback parameters indicate the mouse location in window relative coordinates when the key was pressed. When a new window is created, no keyboard callback is initially registered, and ASCII key strokes in the window are ignored. Passing NULL to glutKeyboardFunc disables the generation of keyboard callbacks. During a keyboard up callback, glutGetModifiers may be called to determine the state of modifier keys when the keystroke generating the callback occurred. To avoid the reporting of key release/press pairs due to auto repeat, use glutIgnoreKeyRepeat to ignore auto repeated keystrokes. There is no guarantee that the keyboard press callback will match the exact ASCII character as the keyboard up callback. For example, the key down may be for a lowercase b, but the key release may report an uppercase B if the shift state has changed. The same applies to sym- bols and control characters. The precise behavior is window system dependent. Use glutSpecialUpFunc for a means to detect non-ASCII key releases. SEE ALSO
