Would also like to know the answer to this one...
I think this is either an oversight or a bad decision. For desktop or browser (I get that it doesn't apply to iOS), users have learned that a hover state reinforces the ability to click on the object to take action. When some "buttons" (even a text object has a hover state) don't have the option to "change cursor to hand over button", it's inconsistent and a bit frustrating.
We have had to go to lengths to achieve this behavior by using a normal button that simple goes to an object that is or is on the popover.
Sure would be nice to add the ability to do this. Did I mention Tabs??? Same issue.
Simply don't use it:
Do those steps:
Create your popover button. Hide it (put 1 in the "Hide Object When" in the Inspector)
Double click on the popover button in layout mode, click on the popover window and give your popover window a name in the Inspector (exp, "Test" )
Use a normal button that does the following: Go to Object "Test" (don't even need to create a script for this).
Here you can choose to show you hand or not.
Hope this helps
I really appreciate the suggestion. This is EXACTLY what I do (complete with a dedicated modular script where I pass other parameters including which field to focus, etc.)
I should have mentioned it, but I'm glad to know others use the technique.
