I took my time to test several things and I found something that worked :
I used createQmlObject(), to load the content of the file, instead of createComponent(). Here is how it looks like :
Tab1.qml :
Item {
id: tab1
property var compo
Component.onCompleted: init()
function init()
{
var xhr = new XMLHttpRequest;
var response
xhr.open("GET", "tab1_qml.qml");
xhr.onreadystatechange = function() {
if (xhr.readyState == XMLHttpRequest.DONE) {
response = xhr.responseText;
compo = Qt.createQmlObject(response, tab1,"tab1_qml.qml")
}
};
xhr.send(); // begin the request
}
function reload()
{
compo.destroy()
init()
}
}
tab1_qml.qml :
Item {
id: tab1qml
property int value: 0
Button{
id: button1
text: tab1qml.value
onClicked: value++
}
Button{
y: button1.height
text: "reload"
onClicked: tab1.reload()
}
Text{
y: button1.height*2
text: "reset ?"
}
}
When I modify my tab1_qml.qml and clic the reload button, it works.
But bad news, it works well on my software, but it doesn't work on QtCreator. As far as I understand, it's because the file is loaded from the ressource, the solution may be to take an external qml file.
Anyway, my problem is solved.
Thanks everyone who responsed.
