Thread: Keyboard Simulation

I was wondering what toolkit or C++ libraries or functions I would use to create a virtual keyboard, just like the default one in Windows. It does not need to be complicated, just very simple.

Thanks!

1) Solution will be Windows specific, so move.
2) Use a GUI toolkit (win32, wxWigdets, MFC, etc), and make all of the keys buttons. When one is clicked, you'll get some sort of message, which you may then handle.

Okay. I know wxWidgets, so that's good, but do you know what code syntax I would use to simulate a keypress? That's all I need, really.

Thanks!

I/O libraries usually implement key mappings that you can alter with some judicious macro editing. For the console the ncurses library is one example. For those keys not defined, you can use getch() to completely reconfigure your kyboard if you so wish.

As for windows... I don't know.

I looked over wxKeyEvent, but it seems that can only be used for reading characters.

I read about some I/O libraries. Would stdio.h be able to be used for a virtual keyboard?

Yes. It could, if I actually understand what you are trying to do.

You could wrap functions like getc and putc to devise your own keyboard events.

Yeah, I probably don't understand too much about what I'm trying to do.

I've found a few Win32 functions (keybd_event(), SendInput()) for keyboard output, but that still doesn't solve my problem of being cross platform. I always like to have a way for my program's source code to be compiled on a different machine and work. It doesn't look like there is going to be a way to do this, though.

There is an easy way to do this. You use #ifdef-s and #ifndefs so it uses different code in different OS.
