	displaying things with G++ ? Remove this text

i am using a G++ compiler under cygwin (unix emulation for windows) and Microsoft Visual C++ simply to maintain the code.
im looking for a simple way to simulate some kind of map where you navigate, move cursor/units, etc...
a very simple way will be fine. but i have problems with the fact that everything is shown in the original text window and will scroll out of sight when you type anything.
i have discovered some cursor control functions, so theoretically i could use colored letters to simulate a map. but that is rather limited and unsatisfactory.

does anyone know of a way to create a new window with displays, pixels, possibly mouse controls.
or can someone help to use that Visual C++ (6.0) thing ? i used it years ago, but have forgotten what little i knew.

I guess you could seek out some kind of graphics library...

Whatever you do, be sure to keep the display component seperate from the unerlying engine to make it easy to rewrite using a different graphics system if you want.

VC++6 should have several tutorials with it, which aren't terrible.

hmm. yeah. i was hoping someone would know one. but for the moment, it doesnt even have to be a real graphics library, rather some commands, standard or not, to control cursor, window, pixels, ...
simple things. just to get started.

you mean i should do all the graphics stuff in an independent module or something, so that the main program simply says something like "graphics.drawThings()" or so ?

Something like that, yes. Just avoid having code that relates to I/O in the same class as code that checks or executes game logic - that's the benefit of object-oriented programming.

Gtk+ is for interfaces... for pushing pixels to the screen, SDL is probably a good idea.
