source: code/trunk/src/orxonox/overlays/OverlayGroup.cc @ 9066

Last change on this file since 9066 was 8309, checked in by dafrick, 14 years ago

Replacing toggleVisibility with show, since the OrxonoxOverlay (& OrxonoxOverlayGroup) doesn't know when the GUI is closed, and toggling doesn't work anyway, since we have no regular keybindings when the GUI is showing.
