Unsolved Problem of updating map data in qml(myclient send qml get)
-
main.cpp:
MyClient receiver;
QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:/map/MapComponent.qml")));
QQmlContext* ctx = engine.rootContext();
ctx->setContextProperty("receiver", &receiver);
receiver.sendToQml("mainsenddata");myclient.h:
class MyClient : public QObject
{
Q_OBJECT
public:
explicit MyClient(QObject *parent = 0);
void SetSocket(int Descriptor);signals:
void sendToQml(QString count);public slots:
void connected();
void disconnected();
void readyRead();
void TaskResult(int Number);private:
QTcpSocket *socket;
};myclient.cpp
QQmlApplicationEngine engine;
MyClient receiver;QQmlContext* ctx = engine.rootContext(); ctx->setContextProperty("receiver", &receiver); engine.load(QUrl(QStringLiteral("qrc:/map/MapComponent.qml"))); receiver.sendToQml("myclientsenddata");
MapComponent.qml
Map {id: map property var imei:1453
imei value to which the value sent from myclient.cpp and main.cpp will be synchronized
Connections{
target:receiver
property variant gelen: 10onSendToQml: { // propertyBinding.valueToQML=count; console.log("Received in QML from C++: " + count); map.imei=count;
up imei value to which the value sent from myclient.cpp and main.cpp will be synchronized
While the first value sent from the maine in Connections is assigned to the popup1 imei value in the mapcomponent, the value from myclient cannot be imported into imei and cannot be shown on the map.
