I want to grab screen of my QML application. But my root QML object is ApplicationWindow
, so I can't use QQuickView
to show it. Instead I have to use QQmlApplicationEngine
.I know how to take screenshot with QQuickView
(QQuickWindow::grabWindow
), but don't know how to take it with QQmlApplicationEngine
.
我的main
文件:
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
ApplicationData appData;
QQmlApplicationEngine engine;
engine.load(QUrl("qrc:///main.qml"));
return app.exec();
}
main.qml
:
import QtQuick 2.1
import QtQuick.Controls 1.1
import QtQuick.Window 2.1
ApplicationWindow {
id: mainWindow
width: appData.screenWidth
height: appData.screenHeight

Rectangle {
id: mainWindowBackground
color: "red"
anchors.fill: parent
}

推荐答案
您可以使用rootObjects()
并将其结果转换为QQuickWindow
:
You can use rootObjects()
and cast its result to QQuickWindow
:
foreach(QObject* obj, engine.rootObjects()) {
QQuickWindow* window = qobject_cast<QQuickWindow*>(obj);
if (window) {
QImage image = window->grabWindow();
qDebug() << image;
}
}
