Fl::add_idle function

[Kubani]

Hello all,

For some reason I need to use of Fl::add_idle function. This site introduces it but doesn't offer an example of how to use it.
http://www.fltk.org/documentation.php/doc-1.1/Fl.html#Fl.add_idle

May you please offer simplest example of it?

simplest example

void callback(void*)
{
    //do something
}
//...
add_idle(callback);

Thanks for the reply but apparently add_idle gets two arguments.

[MiiNiPaa]

Second one is optional. Just like in other fucntions. As documentation states, it is passed to callback function when it is invoked.

OK. Thanks again.
