c++ - How to get QIODevice-like signals for console input (stdin)?

Question

I'm writing console app, based QCoreApplication, and I want to get signals, when user input something into stdin (whole line at once or by characters, it is not important for my app).

QFile not emit signals according to documentation, so any ideas how to get signal if user put in something to stdin?

At now I'm working with qt 4.8.7/linux/amd64, but I want port this code to macosx and windows in the future.

Update

I found solution that should work on *nix based OS, like linux and mac os x:

But what about windows, would it also with with QSocketNotfier?

Answer 1

For Unix (Linux, OS X), this answer has a solution.

For Windows, you cannot use QSocketNotifier: instead, use a QWinEventNotifier on the console handle you obtain from GetStdHandle (see this answer). The code will be almost identical to the Unix variant from the answer above.
