Question to the GUI modders

[h.sie]

hi there,

for my selfmade GUI, I've added Binoc- and UZO-view icons to the stations-menu. now I want to disable these two icons, when the ship is submerged, the same way as the bridge-icon is disabled when submerged. I tried to make Binoc- and UZO-icons be the childs of bridge icon (parent), but that didn't work. does anybody know how to solve that problem?

best wishes,
h.sie
