How to get a Control to only show on the Quickslot scene / fragment?

[static_recharge]

I'm trying to get my toplevel control to only show when the user has the quickslot menu open in the inventory scene. I've looked around these forums and have had lots of success adding my control to other scenes, but the inventory scene is a local scene according to the source code.

I'm pretty sure I'm going to have to use callbacks and monitor the change of scenes myself but I'm not sure where to start or how to use the callback function to correctly achieve this. Basically I just want my control on the screen when the user has the quickslot tab of the inventory menu open and hidden all other times.

Thanks in advance!
