I tried a lot about searching for getting x and y position of mouse click inside the console of windows in C, but I cant find so I am posting here.
I am creating my own text editor project (for fun) and I have to integrate a feature that whenever I click inside the console, the cursor moves to it (click x, y) I don't want to know how to move the cursor but I want to know how to get the click position.
This code can receive all mouse and keyboard and mouse event even mouse clicked:
#include <windows.h>
#include <stdio.h>
HANDLE hStdin;
DWORD fdwSaveOldMode;
VOID ErrorExit(LPSTR);
VOID KeyEventProc(KEY_EVENT_RECORD);
VOID MouseEventProc(MOUSE_EVENT_RECORD);
VOID ResizeEventProc(WINDOW_BUFFER_SIZE_RECORD);
int main(VOID)
{
DWORD cNumRead, fdwMode, i;
INPUT_RECORD irInBuf[128];
int counter=0;
// Get the standard input handle.
hStdin = GetStdHandle(STD_INPUT_HANDLE);
if (hStdin == INVALID_HANDLE_VALUE)
ErrorExit("GetStdHandle");
// Save the current input mode, to be restored on exit.
if (! GetConsoleMode(hStdin, &fdwSaveOldMode) )
ErrorExit("GetConsoleMode");
// Enable the window and mouse input events.
fdwMode = ENABLE_WINDOW_INPUT | ENABLE_MOUSE_INPUT;
if (! SetConsoleMode(hStdin, fdwMode) )
ErrorExit("SetConsoleMode");
// Loop to read and handle the next 100 input events.
while (counter++ <= 100)
{
// Wait for the events.
if (! ReadConsoleInput(
hStdin, // input buffer handle
irInBuf, // buffer to read into
128, // size of read buffer
&cNumRead) ) // number of records read
ErrorExit("ReadConsoleInput");
// Dispatch the events to the appropriate handler.
for (i = 0; i < cNumRead; i++)
{
switch(irInBuf[i].EventType)
{
case KEY_EVENT: // keyboard input
KeyEventProc(irInBuf[i].Event.KeyEvent);
break;
case MOUSE_EVENT: // mouse input
MouseEventProc(irInBuf[i].Event.MouseEvent);
break;
case WINDOW_BUFFER_SIZE_EVENT: // scrn buf. resizing
ResizeEventProc( irInBuf[i].Event.WindowBufferSizeEvent );
break;
case FOCUS_EVENT: // disregard focus events
case MENU_EVENT: // disregard menu events
break;
default:
ErrorExit("Unknown event type");
break;
}
}
}
// Restore input mode on exit.
SetConsoleMode(hStdin, fdwSaveOldMode);
return 0;
}
VOID ErrorExit (LPSTR lpszMessage)
{
fprintf(stderr, "%s\n", lpszMessage);
// Restore input mode on exit.
SetConsoleMode(hStdin, fdwSaveOldMode);
ExitProcess(0);
}
VOID KeyEventProc(KEY_EVENT_RECORD ker)
{
printf("Key event: ");
if(ker.bKeyDown)
printf("key pressed\n");
else printf("key released\n");
}
VOID MouseEventProc(MOUSE_EVENT_RECORD mer)
{
#ifndef MOUSE_HWHEELED
#define MOUSE_HWHEELED 0x0008
#endif
printf("Mouse event: ");
switch(mer.dwEventFlags)
{
case 0:
if(mer.dwButtonState == FROM_LEFT_1ST_BUTTON_PRESSED)
{
printf("left button press \n");
}
else if(mer.dwButtonState == RIGHTMOST_BUTTON_PRESSED)
{
printf("right button press \n");
}
else
{
printf("button press\n");
}
break;
case DOUBLE_CLICK:
printf("double click\n");
break;
case MOUSE_HWHEELED:
printf("horizontal mouse wheel\n");
break;
case MOUSE_MOVED:
printf("mouse moved\n");
break;
case MOUSE_WHEELED:
printf("vertical mouse wheel\n");
break;
default:
printf("unknown\n");
break;
}
}
VOID ResizeEventProc(WINDOW_BUFFER_SIZE_RECORD wbsr)
{
printf("Resize event\n");
printf("Console screen buffer is %d columns by %d rows.\n", wbsr.dwSize.X, wbsr.dwSize.Y);
}
I have heard that it can't be done in C, but if when we get mouse position when mouse is continuously moving then I am sure we may get the click position. But I don't know how.

For example to get the position the user double-clicked you want to replace:
printf("double click\n");
by:
printf("double clicked at x=%d, y=%d\n", mer.dwMousePosition.X, mer.dwMousePosition.Y);
