How to hide toolTips when component is hidden?

[igor_stravinsky]

I've got a view structure that looks like this:

Rectangle A
->Rectangle B
-->Button with tooltip
Text

Either Rectangle A is showing, or Text is showing, but not both. I flip back and forth by changing the opacities.

The problem is that the tooltip for the Button shows up even when Rectangle A has an opacity of 0. I can write code to avoid showing the tooltip in the Rectangle B qml code, but I can't access the opacity of Rectangle A from the Button's code (the two rectangles are in different qml files), and opacity isn't inherited (setting the opacity of Rectangle A has no effect on the opacity of Rectangle B or Button)

What's the best way to avoid showing the Button's tooltip?

I found the solution.

I needed to change the visibility of Rectangle A to be opacity > 0, and then I could test visibility in subviews.
