C Language Console window graphics interface programming eight mouse events

The last time we talked about keyboard events, this time we introduced mouse events. The following is a brief description of the structure of the mouse event and related information.

typedef struct _MOUSE_EVENT_RECORD/mouse event structure body {COORD dwmouseposition;        The current mouse position in the console window buffer DWORD dwbuttonstate;    The state of the mouse button DWORD dwcontrolkeystate;         Control key state DWORD dweventflags;    
Mouse event Type} Mouse_event_record; /* Where the mouse button status Dwbuttonstate possible values are ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ FROM_LEFT_1ST_BUTTON_PR Essed the leftmost mouse button is generally the left mouse button from_left_2nd_button_pressed The second mouse button is pressed in general is the middle mouse button, is the wheel key from_left            _3rd_button_pressed the third mouse button on the left is pressed from_left_4th_button_pressed the fourth mouse button is pressed rightmost_button_pressed The rightmost mouse button is pressed in general is the right mouse button ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Control key state Dwcontrolkeystate and    The same as the keyboard event ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ enhanced_key extension keys are pressed left_alt_pressed The left ALT key is pressed down left_ctrl_pressed left CTRL key is pressed right_alt_pressed right ALT key is pressed right_ctrl_pressed right CTRL key is pressed

The following is a sample program that displays the coordinates of the current mouse in the buffer at the bottom of the console window buffer, clicks the left arrow to output the letter A in the current mouse position, clicks the right button to output the letter B, and double-clicks any mouse button exit function. The procedure is as follows:

#include <stdio.h> #include <windows.h> #include <conio.h> HANDLE handle_in;    
HANDLE handle_out;        Console_screen_buffer_info Csbi;   Defines the window buffer information structure void Displaymouseposition (COORD pos);  Shows the location of the mouse in void gotoxy (int x, int y);      Move the cursor to the position of coordinates (x,y) int main () {handle_in = GetStdHandle (Std_input_handle);    Get the standard input device handle handle_out = GetStdHandle (Std_output_handle);      Obtain the standard output device handle Input_record Mouserec;      Defines the input event structure DWORD res;      Used to store read records COORD POS;  Used to store the mouse current position COORD size = {80, 25};  Window buffer size Getconsolescreenbufferinfo (handle_out, &AMP;CSBI);   Gets the window buffer information setconsolescreenbuffersize (handle_out, size);    
    Sets the window buffer size for (;;)      {Readconsoleinput (handle_in, &mouserec, 1, &res); Read input Event pos = Mouserec.

            Y); Click the left mouse button to output the character a if (Mouserec).    
            Event.MouseEvent.dwButtonState = = from_left_1st_button_pressed) {putchar (' A '); //Click the right mouse button to output the character B if (Mouserec).    
            Event.MouseEvent.dwButtonState = = rightmost_button_pressed) {putchar (' B '); //Double Repel out if (mouserec.    
            Event.MouseEvent.dwEventFlags = = Double_click) {break;    
    }} CloseHandle (Handle_out);    
    CloseHandle (handle_in);

    } void Gotoxy (int x, int y) {COORD pos = {x, y};    
SetConsoleCursorPosition (Handle_out, POS); }
