Qt Get Mouse Position

In Qt, you can use the QCursor class to retrieve the current position of the mouse. The specific steps are as follows:

1. 导入QCursor类：
2. import QCursor
3. Use the QCursor::pos() method to obtain the current global position of the mouse.
4. Get the current position of the cursor and store it in a variable called cursorPos.

The QPoint class represents the coordinates of a point, with the x() method returning the x-coordinate of the point and the y() method returning the y-coordinate of the point.

For example, the following code demonstrates how to retrieve and display the position of the mouse:

#include <QApplication>
#include <QCursor>
#include <QDebug>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    // 获取鼠标当前位置
    QPoint cursorPos = QCursor::pos();

    // 输出鼠标位置的x和y坐标
    qDebug() << "Mouse Position: (" << cursorPos.x() << ", " << cursorPos.y() << ")";

    return a.exec();
}
