// This global variable contains the number of currently opened modal dialogs.
// When it is non null, the global menu used in Ubuntu Unity needs to be
// explicitly disabled as this doesn't currently happen on its own due to a bug
// in Unity, see https://bugs.launchpad.net/indicator-appmenu/+bug/674605
//
// For this to work, all modal dialogs must use wxOpenModalDialogLocker class
// below to increment this variable while they are indeed being modally shown.

// This variable is defined in src/gtk/toplevel.cpp
