QT实现带动态弹出动画的自定义通知提示框
资源内容介绍
Qt中经常会用到提示框，用于交互操作！QMessageBox是被大多数人用到的，用起来是很方便，但是控件类型、大小、布局、样式、往往不是开发者想要的。本实例实现的Notification控件，是一种悬浮在角落的通知提醒框 #include "notification.h"#include <QPainter>#include <QStyleOption>#include <QGraphicsDropShadowEffect>#include <QScrollBar>#include <QPropertyAnimation>#include <QApplication>#include <QScreen>static int nAppearTime = 200;
