QT自动保存截图带命名模板

Question

我想每 10 秒以不同的名称保存多个屏幕截图，

i want to save like this

here my current code

      QScreen *screen = QGuiApplication::primaryScreen();
      QPixmap pic  = screen->grabWindow(0);
      pic.save("C:/Users/Coding/Desktop/img/desktop_1.png");

Answer 1

将此功能包装到 class 中。将静态计数器添加到您的 class（例如 static long long counter {0};）声明如下：QString m_path_to_image; 将您的代码更改为

pic.save(path_to_image.arg(m_counter));

Answer 2

您可以将 QString 格式化为您的文件名并在末尾附加一个计数器，如下所示：

int counter = 1;
auto fileName = QString("C:/Users/Coding/Desktop/img/desktop_%1.png").arg(counter);
counter++;
pic.save(fileName);
