module "QtNetwork" is not installed

[zeroalpha]

Hello. I am new to QML and am really loving it.

I am trying to make a TCP client app with Qt 6.4.3 but I am getting an error: QML module not found (QtNetwork)

In QT Creator I did: Create Project>Application (Qt)>Qt Quick Application>qmake

This is my qml code:

import QtQuick 2.15
import QtQuick.Window 2.15
import QtNetwork

Window {
    visible: true
    width: 400
    height: 300
    title: "TCP Client"

    property string host: "localhost"
    property int port: 1234

    TextField {
        id: messageField
        anchors.top: parent.top
        anchors.horizontalCenter: parent.horizontalCenter
        width: parent.width * 0.8
        placeholderText: "Enter message"
        onTextChanged: sendButton.enabled = text.trim().length > 0
    }

    Button {
        id: sendButton
        anchors.top: messageField.bottom
        anchors.horizontalCenter: parent.horizontalCenter
        text: "Send"
        enabled: false
        onClicked: {
            var socket = new QTcpSocket();
            socket.connectToHost(host, port);
            if (socket.state === QTcpSocket.ConnectedState) {
                var message = messageField.text.trim();
                socket.write(message);
                socket.flush();
                socket.disconnectFromHost();
                messageField.text = "";
            } else {
                console.log("Failed to connect to " + host + ":" + port);
            }
        }
    }
}

and this is my .pro file code:

QT += quick network

SOURCES += \
        main.cpp

resources.files = main.qml 
resources.prefix = /$${TARGET}
RESOURCES += resources

# Additional import path used to resolve QML modules in Qt Creator's code model
QML_IMPORT_PATH =

# Additional import path used to resolve QML modules just for Qt Quick Designer
QML_DESIGNER_IMPORT_PATH =

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

Where is Qt Network? In the maintenance tool, I can't see Qt Network. Is it a seperate install like qt multimedia?

Hi,

Use the JavaScript network API. To the best of my knowledge, the Qt Network module is not exposed to QtQuick.

ok figured it out. Here is the working .pro file:

QT += quick quickcontrols2 network

CONFIG += c++11

SOURCES += main.cpp

RESOURCES += qml.qrc

QML_IMPORT_PATH = $$PWD

QML_DESIGNER_IMPORT_PATH = $$QML_IMPORT_PATH

QQmlApplicationEngine {
    qmlProtectModule("Qt.Network", 1);
}

# Additional compiler flags (if any)
QMAKE_CXXFLAGS += -Wall

# Additional linker flags (if any)
QMAKE_LFLAGS +=

# Additional libraries (if any)
LIBS +=

This .pro file specifies that the project requires the QtQuick, QtQuickControls2, and QtNetwork modules, and sets the C++ version to c++11. The main.cpp file is listed as the project source file, and the qml.qrc file is listed as a project resource file.

The QML_IMPORT_PATH and QML_DESIGNER_IMPORT_PATH variables are set to the current working directory, and the QQmlApplicationEngine line adds a module import statement for the Qt.Network module to avoid a QML import error.
