OpenGL GLUT Registration callback function [GO]

The registration callback function of OpenGL

void Glutdisplayfunc (void (*func) (void));

Displays the callback function for the current window setting

void Glutoverlaydisplayfunc (void (*func) (void));

Registers the display callback function of the overlapping layer of the current window

void Glutreshapefunc (void (*func) (int width, int height));

Specifies the function that is called when the size of the window changes

void Glutkeyboardfunc (void (*func) (unsigned char key, int x, int y));

Registers the keyboard callback function for the current window

void Glutmousefunc (void (*func) (int button, int state, int x, int y));

Registers the mouse callback function for the current window

Func is a registered mouse callback function that completes the handling of mouse events

button is the button for the mouse, the constant defined for the following

Glut_left_button	Left mouse button
Glut_middle_button	Middle mouse button
Glut_right_button	right mouse button

State is the action of the mouse button, the constants defined below

Glut_up	Mouse Release
Glut_down	mouse button down

X, y is the mouse down, and the cursor is positioned relative to the upper-left corner of the window

void Glutmotionfunc (void (*func) (int x, int y));
void Glutpassivemotionfunc (void (*func) (int x, int y));

Set the move callback function, set the current mouse movement function

Func is a registered mouse move function

X, y is the mouse down, and the cursor is positioned relative to the upper-left corner of the window
Call the Glutmotionfunc registered callback function when the mouse is pressed and moved in the window
Call the Glutpassivemotionfunc registered callback function when the mouse moves through the window

void Glutvisibilityfunc (void (*func) (int state));

Sets the visual callback function for the current window

Func for the specified visual callback function

State represents the visibility of the window for the following constants:

Glut_not_visible	Window is completely invisible
Glut_visible	window visible or partially visible

This function sets the visual callback function of the current window, and when the window's visibility changes, the window's visual callback function is called. As long as any one of the pixels in the window is visible, or any one of his child windows is visible, glut thinks the window is visible.

void Glutentryfunc (void (*func) (int state));

Set a callback function for the mouse to enter and exit the window

Func is a registered mouse in and out of the callback function

State is in and out of the mouse, and is one of the following constants:

Glut_left	Mouse Out of window
Glut_right	Mouse into the window

This function is called when the window gets focus or loses focus, when the mouse enters the window area and clicks, the state is Glut_right, and the state is glut_left when the mouse leaves the window area and clicks another window.

void Glutspecialfunc (void (*func) (int key, int x, int y))

Sets the callback function for the specific key of the current window

Func is a callback function that registers a specific key

Key is a specific key that is pressed, as defined by the following constants:

Key constant	Describe
Glut_key_f1	F1 function keys
Glut_key_f2	F2 function keys
Glut_key_f3	F3 function keys
Glut_key_f4	F4 function keys
Glut_key_f5	F5 function keys
Glut_key_f6	F6 function keys
Glut_key_f7	F7 function keys
Glut_key_f8	F8 function keys
Glut_key_f9	F9 function keys
Glut_key_f10	F10 function keys
Glut_key_f11	F11 function keys
Glut_key_f12	F12 function keys
Glut_key_left	Left ARROW key
Glut_key_up	Up ARROW key
Glut_key_right	Right ARROW key
Glut_key_down	Down ARROW key
Glut_key_page_up	PageUp Key
Glut_key_page_down	PageDown key
Glut_key_home	Home key
Glut_key_end	End key
Glut_key_insert	Insert key

X, y is the coordinates of the mouse when the key is pressed, relative to the upper-left corner of the window, in pixels
Note: The ESC, enter, and delete keys are generated by the ASCII code.

void Glutmenustatusfunc (void (*func) (int status, int x, int y));

Set menu State callback function

Func is a registered menu-state callback function

Status is whether the menu is currently used, the constants defined for the following

Glut_menu_in_use	menu is in use
Glut_menu_not_in_use	Menu not being used

X, y is the mouse-down style, where the cursor is relative to the upper-left corner of the window

This function when the GLUT program determines whether the menu is being used, when the popup menu, call the Registered menu state callback function, while the status is set to constant Glut_menu_in_use, when the menu is finished, also call the menu state callback function, the status variable becomes glut _menu_not_in_use. Menus that pop up from the popup menu do not produce a menu-state callback procedure. Each GLUT program has only one menu-state callback function.

Glutspaceballrotatefunc

Glutspaceballbuttonfunc

Glutbuttonboxfunc

Glutdialsfunc

Gluttabletmotionfunc

Gluttabletbuttonfunc

void Glutmenustatusfunc (void (*func) (int status, int x, int y));

Set menu State callback function

Func is a registered menu-state callback function

Status indicates whether menus are currently used, constants defined for the following

Glut_menu_in_use	menu is in use
Glut_menu_not_in_use	Menu not being used

X, y indicates the mouse is pressed and the cursor is positioned relative to the upper-left corner of the window

This function when the GLUT program determines whether the menu is being used, when the popup menu, call the Registered menu state callback function, while the status is set to constant Glut_menu_in_use, when the menu is finished, also call the menu state callback function, the status variable becomes glut _menu_not_in_use. Menus that pop up from the popup menu do not produce a menu-state callback procedure. Each GLUT program has only one menu-state callback function.

void Glutidlefunc (void (*func) (void));

Set the idle callback function

Func represents a function that is called when the system is idle, in the form of void func (void)

void Gluttimerfunc (unsigned int msecs, void (*func) (int value), int value);

Registers a callback function that is called by glut once the specified time value arrives

Msecs is the time to wait

Func is a registered function

Value is a specified numeric value that is used to pass into the callback function func

This function registers a callback function that invokes the registered function when the specified number of milliseconds arrives, and the value parameter is used to pass parameters to the registered function.
