Control and Keyboard Input

Hello, C++ novice back again, and I now have a new question which I can't seem to find a clear answer to on the Internet.

First of all, I'm trying to write a functional text editor, and I'm wondering how to get my program to recognize a key combination (<ctrl>+O for opening files, for example) and using that information to preform whatever function. However, the problem is, I don't know how C++ handles key combinations.

Could somebody help me by informing me of a function that can preform key combinations? Thank you for taking your time.

The answer depends on your platform. What OS/compiler are you using?

I'm currently developing for Windows, and I'm using Dev C++ as my compiler.

How are you storing each line whilst you're editing the file?

I'm mostly in the conceptual stage of development (I haven't written any actual source code yet), so I haven't worked that out. What I was wondering was whether or not there was a way to get the computer to recognize keyboard combinations.

If you are using command line, then you probably will need a "read keyboard without waiting for enter", which there is a sample of in the FAQ section. It would then return CTRL-O as the value 15 (O being the 15th letter in the alphabet, and can be expressed as 'O'-64 or 'O'-('A'-1)).

There are OTHER ways you can determine which key was pressed and what modifier keys (CTRL, SHIFT, ALT, etc) are currently active.

Will this be a console application or a windows application?

If it's console, look at http://www.adrianxw.dk/SoftwareSite/index.html.

If it's windows, then you have a lot more to learn than just keyboard handling. You should start with windows programming tutorials and/or books or consider learning a library like wxWidgets.
