一、右键菜单
右键菜单实现：通过重写contextMenuEvent(QContextMenuEvent *event)事件，QMenu+QAction即可完美实现！
重写voidcontextMenuEvent(QContextMenuEvent*event)事件
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | void Form::contextMenuEvent(QContextMenuEvent * event ) { //创建菜单、菜单项 QMenu *pop_menu = new QMenu(); QAction *add_images_action = new QAction( this ); QAction *add_folder_action = new QAction( this ); QAction *remove_selected_action = new QAction( this ); QAction *remove_all_action = new QAction( this ); add_images_action->setText(tr( "add images" )); add_folder_action->setText(tr( "add folder" )); remove_selected_action->setText(tr( "remove selected images" )); remove_all_action->setText(tr( "remove all images" )); //清除原有菜单 pop_menu->addAction(add_images_action); pop_menu->addAction(add_folder_action); pop_menu->addAction(remove_selected_action); pop_menu->addAction(remove_all_action); //菜单出现的位置为当前鼠标的位置 pop_menu->exec(QCursor::pos()); } |
二、按钮菜单
使用QPushButton(QToolButton)+QMenu+QAction即可完美实现！
界面拖入一个pushButton按钮；代码实现
| 1 2 3 4 5 6 7 8 9 | QMenu *remove_menu = new QMenu(); QAction *remove_selected_action = new QAction(remove_menu); QAction *remove_all_action = new QAction(remove_menu); remove_menu->addAction(remove_selected_action); remove_menu->addAction(remove_all_action); ui->pushButton->setMenu(remove_menu); ui->pushButton->setText(tr( "remove" )); remove_selected_action->setText(tr( "remove selected watermarks" )); remove_all_action->setText(tr( "remove all watermarks" )); |
三、托盘菜单
托盘菜单实现：通过QSystemTrayIcon+QMenu+QAction实现；
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | QSystemTrayIcon *system_tray = new QSystemTrayIcon(); //放在托盘提示信息、托盘图标 system_tray ->setToolTip(QString( "我就是托盘" )); system_tray ->setIcon(QIcon( ":/sx1.png" )); //TrayMenu *tray_menu = new TrayMenu(); QMenu *remove_menu = new QMenu(); QAction *remove_selected_action = new QAction(remove_menu); QAction *remove_all_action = new QAction(remove_menu); remove_menu->addAction(remove_selected_action); remove_menu->addAction(remove_all_action); remove_selected_action->setText(tr( "remove selected watermarks" )); remove_all_action->setText(tr( "remove all watermarks" )); system_tray->setContextMenu(remove_menu); //点击托盘执行的事件 connect(system_tray , SIGNAL(activated(QSystemTrayIcon::ActivationReason)), this , SLOT(iconIsActived(QSystemTrayIcon::ActivationReason))); connect(remove_menu, SIGNAL(showWidget()), this , SLOT(showNormal())); //显示托盘 system_tray->show(); //托盘显示提示信息 system_tray->showMessage(QString( "托盘标题" ), QString( "托盘显示内容" )); |
注：关闭和最小化进入到托盘代码
| 1 2 3 4 5 6 7 8 9 10 11 12 13 | void Form::closeEvent(QCloseEvent *e) { this ->hide(); e->ignore(); } void Form::changeEvent(QEvent *e) { if ((e->type()==QEvent::WindowStateChange)&& this ->isMinimized()) { this ->hide(); e->ignore(); } } |
