我想要做的事情很简单,就是从C++更改一些QML对象的属性(文本:) ,但是我失败了。任何帮助都将不胜感激。
我没有收到任何错误消息,窗口显示出来了,只是文本属性没有像应该一样改变。 我甚至有没有错过什么?!
我尝试的是这个:
main.cpp
#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QQuickView>
#include <QQuickItem>
#include <QQmlEngine>
#include <QQmlComponent>
#include <QString>
int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;
QQmlComponent component(&engine, QUrl::fromLocalFile("main.qml"));
QObject *object = component.create();
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
QString thisString = "Dr. Perry Cox";
object->setProperty("text", thisString); //<--- tried instead of thisString putting "Dr. ..." but nope.
delete object;
return app.exec();
}
main.qml
import QtQuick 2.2
import QtQuick.Window 2.1
Window {
visible: true
width: 360
height: 360
MouseArea {
anchors.fill: parent
onClicked: {
Qt.quit();
}
}
Text {
id: whot
text: ""
anchors.centerIn: parent
font.pixelSize: 20
color: "green"
}
}
