POINT Structure
The POINT structure specifies a coordinate in two-dimensional space. This structure is used by many Windows functions, such as those that deal with screen coordinates, cursor positions, and window dimensions.
Syntax
typedef struct _POINT {
LONG x;
LONG y;
} POINT;Members
| Member | Type | Description |
|---|---|---|
x |
LONG |
The x-coordinate of the point. This member can be a signed integer. |
y |
LONG |
The y-coordinate of the point. This member can be a signed integer. |
Requirements
| | | | |
|---|---|
| SDK | Windows.h |
| Header | wingdi.h (for GDI functions), winuser.h (for user interface functions) |
Remarks
The POINT structure is the basis for other structures like POINTEX. The coordinates are typically relative to the device context's origin.
Example
The following C++ code snippet demonstrates how to declare and initialize a POINT structure:
#include <windows.h>
#include <iostream>
int main() {
POINT pt1;
pt1.x = 100;
pt1.y = 200;
POINT pt2 = {50, 75}; // Using aggregate initialization
std::cout << "Point 1: (" << pt1.x << ", " << pt1.y << ")" << std::endl;
std::cout << "Point 2: (" << pt2.x << ", " << pt2.y << ")" << std::endl;
return 0;
}
