Returns the current cascade level of IupMainLoop. When no calls were done, return value is 0.


int IupMainLoopLevel(void); [in C]
iup.MainLoopLevel() -> ret: number [in Lua]

Returns: the cascade level.


You can use this function to check if IupMainLoop was already called and avoid calling it again.

A call to IupPopup will increase one level.
