1.先进行menu创建 auto recentMenu = new QMenu(); for(int i=0;i<MaxRecentFiles;i++) { recentFileActs[i] = new QAction(this); recentFileActs[i]->setVisible(false); recentMenu->addAction(recentFileActs[i]); c

1.大体思路是使用qlabel 加载图片，使用qtimer 定时，timeout 时更新图片#include "widget.h"#include "ui_widget.h"#include <QDebug>#include <QTimer>Widget::Widget(QWidget *parent) : QWidget(parent), ui(new Ui::Widget){ ui->setupUi(this); path =

1.Qt之msvc-version.conf loaded but QMAKE_MSC_VER isn't set解决方法 ：在lib 中\mkspecs\common\msvc-version.conf 文件中添加 指定msvc 版本 1900 是20152.Qt编译通过，运行时出现the process was ended forcefully问题的解决方案参考https://blog.youkuaiyun.com/Mr_include/article/details/87933839...

1.头文件加上#include <QTextCodec>2.QString 获取拖拽或file对话框信息3.先转为std::string ，然后由string 转为QString QTextCodec *code = QTextCodec::codecForName("GB2312");// fix Chinese name； std...
