qml + Qt.createcomponent + visual studio , component is not ready

QtBeginnnnner

I could use Qt.createcomponent("PrinterDialog.qml") with qmlscene main.qml,and a new dialog is showed .
but while I generated a visual studio project , createcomponents always failed with "component not ready", even if I have copied PrinterDialog..qml to all the folders.

here is the code
main.cpp
int main(int argc, char *argv[]) {
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;

engine.load(QUrl(QStringLiteral("qrc:///main.qml")));
if (engine.rootObjects().isEmpty()) return -1;

return app.exec();

}

main.qml

RowLayout {

ToolButton {

console.log("File menu click1");
menu1.open();
}
Menu {

console.log("File menu click2");

@QtBeginnnnner said in qml + Qt.createcomponent + visual studio , component is not ready:

./Printer/PrinterDialog.qml

Clearly it is path issue. Did you add this in resource file ? What is the path in resource file ? Just try to specify the path like this ":/Printer/PrinterDialog.qml".

QtBeginnnnner

Although I don't know the mechanism and logic it is .
I only adjust path of qrc and path of createComponent to be same , and then it works .
as my opinion , once qml is successfully loaded with qrc file , I could use it directly , like"Qt.createComponent("PrinterDialog.qml");"
Why I have to still load qml file with the path Qt.createComponent("./Printer/PrinterDialog.qml");
so weird...................................

worked modification as follows:
in qml file:
var component = Qt.createComponent("./Printer/PrinterDialog.qml");
if( component.status == Component.Ready )
{
win = component.createObject(root);
win.show();
}
else
{
console.log("component not ready2");
}

in qrc file:
<RCC>
<qresource prefix="/">
<file>main.qml</file>
<file>./Printer/PrinterDialog.qml</file>
</qresource>
</RCC>

It is path you are placing in resource. It is like a directory only. So you have to specify the path.

ok thanks very much
