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！

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！

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"
));

QSystemTrayIcon *system_tray =

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
