I'm working on a QML application that has a lot of property bindings: hundreds of objects are tracked and displayed in different forms like Qt3D/QCanvas.
When I'm on a separate page of the application those property bindings for x/y locations and relative sizes are still happening. How can I stop them? I know I could bind the properties based on whether they're visual or not but that is a lot of unnecessary code:
x: visible ? tracking.location(index).x : 0
I would have to wrap a ton of bindings like that. Any other solutions?
You can use the Binding
element. You can specify target, property, value and condition to activate the binding.
Binding on x {
value: tracking.location(index).x
when: visible
}
You can also use Loader{} and set active property to false. This will disable the whole item.
