ScrollIndicator.vertical: ScrollIndicator { }
}
}Place a list view in the middle , The view has a vertical indicator .
When you press an item in the view , The corresponding page enters the stack view .
Click the button on the left of the toolbar , Current page out of stack ：
Action
{
id: navigateBackAction
icon.name: stackView.depth > 1 ? "back" : "drawer"
onTriggered:
{
if (stackView.depth > 1)
{
stackView.pop()
listView.currentIndex = -1
} else {
drawer.open()
}
}
}Switch theme function
In the loading main interface qml Give initialization attribute to file .
