Qt QML change item of a page dynamically
Solution 1:
You can define an alias to the Loader's item property inside BasePage, like that:
property alias contentItem: loader.item
And refer to it instead of contentitem within DerivedPage.
Putting it all together:
// BasePage.qml
Item {
property alias content: loader.sourceComponent
property alias contentItem: loader.item
signal topBarLeftButtonClicked()
Loader { id: loader }
}
// DerivedPage.qml
BasePage {
onTopBarLeftIconClicked: { contentItem.text = "clicked" }
content: Component { TextField { } }
}
