我正在编写一个QtQuick桌面应用程序。我在其中使用c ++(用于功能)和QML(用于UI)。 我使用QQuickView来显示用QML编写的界面。
我希望此应用程序在最小化时驻留在系统托盘中。
我的意思是与此示例类似的功能。 http://qt-project.org/doc/qt-4.8/desktop-systray.html。 我正在尝试实现此功能,但无法在我的Qt Quick应用程序中找到一种方法。
这是我的main.cpp代码:
#include <QGuiApplication>
#include <QQmlEngine>
#include <QQmlContext>
#include <QQmlFileSelector>
#include <QQuickView>
#include "myapp.h"
int main(int argc, char* argv[])
{
QGuiApplication app(argc,argv);
app.setApplicationName(QFileInfo(app.applicationFilePath()).baseName());
QDir::setCurrent(qApp->applicationDirPath());
MyApp myappObject;
QQuickView view;
view.connect(view.engine(), SIGNAL(quit()), &app, SLOT(quit()));
view.rootContext()->setContextProperty("myappObject", &myappObject);
new QQmlFileSelector(view.engine(), &view);
view.setSource(QUrl("qrc:///myapp.qml"));
view.setResizeMode(QQuickView::SizeRootObjectToView);
view.show();
return app.exec();
}
请提供任何提示/指示来帮助完成此操作。
感谢。

我今天面临同样的挑战,最终在main()中使用了以下解决方案。使用Qt 5.3时,对我来说很有用。您当然应该实现一种更好的方法来检查第一个根对象是否是您的应用程序窗口对象。
#include <QApplication>
#include <QQmlApplicationEngine>
#include <QMessageBox>
#include <QAction>
#include <QMenu>
#include <QSystemTrayIcon>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
if (!QSystemTrayIcon::isSystemTrayAvailable()) {
QMessageBox::critical(0, QObject::tr("Systray"),
QObject::tr("I couldn't detect any system tray "
"on this system."));
return 1;
}
QApplication::setQuitOnLastWindowClosed(false);
QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:///main.qml")));
QObject *root = 0;
if (engine.rootObjects().size() > 0)
{
root = engine.rootObjects().at(0);
QAction *minimizeAction = new QAction(QObject::tr("Mi&nimize"), root);
root->connect(minimizeAction, SIGNAL(triggered()), root, SLOT(hide()));
QAction *maximizeAction = new QAction(QObject::tr("Ma&ximize"), root);
root->connect(maximizeAction, SIGNAL(triggered()), root, SLOT(showMaximized()));
QAction *restoreAction = new QAction(QObject::tr("&Restore"), root);
root->connect(restoreAction, SIGNAL(triggered()), root, SLOT(showNormal()));
QAction *quitAction = new QAction(QObject::tr("&Quit"), root);
root->connect(quitAction, SIGNAL(triggered()), qApp, SLOT(quit()));
QMenu *trayIconMenu = new QMenu();
trayIconMenu->addAction(minimizeAction);
trayIconMenu->addAction(maximizeAction);
trayIconMenu->addAction(restoreAction);
trayIconMenu->addSeparator();
trayIconMenu->addAction(quitAction);
QSystemTrayIcon *trayIcon = new QSystemTrayIcon(root);
trayIcon->setContextMenu(trayIconMenu);
trayIcon->setIcon(QIcon(":/resources/DatagnanLogoColor.png"));
trayIcon->show();
}
return app.exec();
}

将Windows类(windows.c ++ / window.h)从systray示例复制到项目中,必要时将其移植到Qt5并从主文件中打开:
int main(int argc, char* argv[])
{
// ...
QQuickView view;
// ...
view.show();
Window window;
window.show();
return app.exec();
}
