Expose your component through a property of file's root item.

Because you didn't ask a question. Use the button to "Ask as question" and then you'll have the "Mark as solved" that should appear.

@kshegunov Yap, Thanks, Thanks. :-) Now It's generate all the required files, I also need to add QWidgets in Select Required Models. Best Regards, IL

@kylecorver Can you post the complete program? The original isn't a a valid Qml document, leading to guessing about which errors will or will not occur. The OS and Qt version used might also be relevant.

Maybe //main.qml: import QtQuick 2.5 Loader { id: loader source: "MyComponent.qml" onLoaded: { loader.item.property1 = "secret" loader.item.property2 = 777 } } //MyComponent.qml: import QtQuick 2.0 Rectangle { id: rect property string property1 property int property2 TextEdit { id: text_edit anchors.centerIn: parent text: property1 + property2 } } or //main.qml: import QtQuick 2.5 Item { id: main width: 200; height: 200 property string property1: "secret" property int property2: 777 Loader { id: loader source: "MyComponent.qml" onLoaded: loader.item.text = property1 + property2 } } //MyComponent.qml: import QtQuick 2.0 Rectangle { id: rect property alias text: text_edit.text TextEdit { id: text_edit anchors.centerIn: parent text: property1 + property2 } } or import QtQuick 2.0 Rectangle { id: rect TextEdit { id: text_edit anchors.centerIn: parent // rect.parent -> loader; rect.parent.parent -> Item with id 'main' text: (rect.parent.parent.property1 !== undefined) ? rect.parent.parent.property1 : "" } }

@shav When I call setSource() method the old content removed from memory and all connects to signals is removed? AFAIK, Yes.

I know this is marked as solved, but just as an aside: to do this with a Loader, you could use a Settings object to store the properties that should be reset to restore the state of the user's view - still a Labs feature just now, but it works very nicely.

@Maxim-DC Yes it is possible. You can find an example here. The exact file in it where it is used.

hello, can you tell us how you solve your problem? thank you.
