Question

我正在制作一个程序，我需要用户填写一些信息。我有我的main.qml菜单和我的页面SubPage.qml，用户可以访问该表单来填充它。

现在表单已填满，我想将信息发送到main.cpp来处理它。我所有的尝试都没有成功......

这里是我的main.cpp

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QQmlComponent>
#include <QQuickView>
#include <QtQml>
#include <QDebug>
#include "generalsettings.h"

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

    QQmlApplicationEngine engine2;

    GeneralSettings generalSettings1;
    QQmlComponent component(&engine2, QUrl((QStringLiteral("qrc:/SubPage.qml"))));

    QObject *element = engine.rootObjects().value(0);
    //QQuickWindow *window = qobject_cast<QQuickWindow *>(element);

    QObject::connect(component, SIGNAL(saveGeneralSettings(QString)),
                       &generalSettings1, SLOT(registerGeneralSettings(QString)));

    return app.exec();
}

我的SubPage.qml 我只把按钮带有信号

 Button{
     id:buttonRight
     text:"Right"
     anchors.margins: 10
     x:visualConditionsContainer.x + maxCardWidth/2 - buttonRight.width + visualConditionsContainer.width/2
     y:maxCardHeight +visualConditionsContainer.y +40
     onClicked:{
        if(datePickerContainer.x != pageGeneralSettings.width){
            selectedCard = datePickerContainer
            if(currentTimeDate.checked){
                timePickerContainer.x = pageGeneralSettings.width
            }
            animateGoRight.start()
        }else if(timePickerContainer.x != pageGeneralSettings.width){
            selectedCard = timePickerContainer
            animateGoRight.start()
        }else if(globalConfigContainer.x != pageGeneralSettings.width){
            selectedCard = globalConfigContainer
            animateGoRight.start()
        }else if(visualConditionsContainer.x != pageGeneralSettings.width){
            pageStack.push(Qt.resolvedUrl("PageModifications.qml"))
            DataManager.registerGeneralSettings(currentTimeDate.checked,Qt.formatDate(datePicker.selectedDate, "d MMMM yyyy"),Qt.formatTime(timePicker.getCurrentTime(), "hh:mm:ss"), dayDurationTextField.text,isFarCulling.checked, isEnableLensFlare.checked,radioButton(rateReflection.current.text), sliderVisibility.value, sliderLight.value, sliderTurbidity.value )
            pageGeneralSettings.saveGeneralSettings("coucou c'est QML")
        }

     }
     backgroundColor: Theme.accentColor
 }

谢谢你的帮助

QML中的插槽/信号，其他页面不是main.qml
