    // therefore seems not to respond).
    // This enum is meant to save current state of affairs, i.e., if the event forwarding is ok to do or not. It is only used on Linux
    // and OSX by some #ifdefs. It also stores information whether OnListBoxSelection is supposed to change the checkbox status,
    // or if it changed status on its own already (which happens when the square is clicked). More comments in OnCheckListBox(...)
    // There indeed is a better solution, maybe making a custom event used for the event passing to distinguish the original and passed message
    // and blocking one of them on OSX and Linux. Feel free to refactor, but carefully test on all platforms.
