Hello all.
I have the following very simplified situation where all my screens should
belong
to a hierarchy of partial screens, so that there is no duplication and I can
easily
change behaviour and design at one place (amonst other things). For example:
[BaseScreen] <----- [SomePartScreen] <----- [MainScreen]
<----- [AboutScreen]
<----- [OtherPartScreen] <----- [...Screen]
And so forth. Now the problem is this:
SomePartScreen.qml:
BaseScreen {
Rectangle {
id: rectOne
anchor.left: parent.anchors.left
}
Rectangle {
id: rectTwo
anchor.right: parent.anchors.right
}
}
If I want to put a rectangle between rectOne and rectTwo in a further "derived"
screen (e.g. AboutScreen), I need access to at least one of their anchor
properties.
Unfortunately due to the way QML is designed, I cannot access the childs of my
parent
class. I have also not managed to successfully alias the anchor property of
either
rectangles in the BaseScreen root because it always resulted in an error when I
accessed it in e.g. AboutScreen ("Cannot anchor to a null item.").
Is there any way, trick or solution I don't know about to solve this problem or
do
I really need to duplicate common layout / behaviour through all screens?
I know I could break down everything to separate elements and reuse those, which
is unfortunately not feasible for my current project for various reasons. :(
Thanks for any input and help...
So long,
Matthias Dahl
