很遗憾，这招在qml2中是行不通的
我的试验
screenCapture.hpp
#include <QObject>
class QString;
class QQuickView;
class screenCapture : public QObject
{
Q_OBJECT
public:
explicit screenCapture(QQuickView *parent = 0);
public slots:
void capture(QString const &path) const;
private:
QQuickView *currentView_;
};
screenCapture.cpp
#include <QPixmap>
#include <QQuickView>
#include <QString>
#include "screenCapture.hpp"
screenCapture::screenCapture(QQuickView *currentView) :
QObject(0), currentView_(currentView)
{
}
void screenCapture::capture(QString const &path) const
{
QPixmap::grabWidget(currentView_).save(path);
}
main.cpp
#include <QGuiApplication>
#include <QQuickPaintedItem>
#include <QQuickView>
#include <QQmlContext>
#include "screenCapture.hpp"
int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);
qmlRegisterType<screenCapture>("Image", 1, 0, "ScreenCapture");
qmlRegisterType<saveAbleImage>("Image", 1, 0, "SaveAbleImage");
QQuickView view;
view.setResizeMode(QQuickView::SizeRootObjectToView);
view.setSource(QStringLiteral("/Users/Qt/program/experiment_apps_and_libs/funnyCamera/qml/funnyCamera/main.qml"));
view.show();
screenCapture screenClass(&view);
view.rootContext()->setContextProperty("screenObject", &screenClass);
return app.exec();
}
main.qml
import QtQuick 2.0
import "logic.js" as Logic
import "style.js" as Style
Rectangle{
id : root
width : 1024
height : 768
MouseArea{
anchors.fill: root
onClicked: {
console.log("save image")
screenObject.capture("Pictures/saveTest.jpg")
}
}
}
error messages
QPixmap::grabWidget is deprecated, use QWidget::grab() instead
QMetaObject::invokeMethod: No such method QQuickView::grab(QRect)
