Write and compile an OpenGL program in C++ which implements the ''free-
hand drawing'' tool. A free hand drawing tool allows the user to draw lines as
the user moves the mouse pointer freely in the screen. Your program should
have 2 additional features:

a). The program should only draw when the left mouse button is held down.

b). There should be a menu bound to the right mouse button which allows
the user to clear the screen, change between colors (red green and blue)
or exit the application.

Hint: dene two handler functions, one that deals with mouse clicks and one
that deals with mouse motion. In order to process menu callbacks dene a menu
function as well which manages the menus

推荐答案

我们不为人们做作业.这不是因为我们认为自己在这种普通的编码上胜于其他，而是因为如果我们为您完成工作，您将不会学到任何东西.那天，当我上学时，我的老师给了我完成作业所需的一切.我希望这些条件在现代学校中仍然盛行.即使他没有(或者当他提供上述信息时您根本没有注意)，您仍然拥有大量的互联网资源供您直接使用，您所要做的就是键入"google"到达那里.

We don''t homework for people. It''s not because we feel that we''re superior or above that kind of mundane coding, but because YOU won''t learn anything if WE do the work for you. Back in the day, when I was going to school, my instructor gave me everything I needed to complete homework assignments. I would hope those conditions still prevail in modern schools. Even if he didn''t (or you simply weren''t paying attention when he WAS providing said information), you have overwhelmingly vast resources of the internet at your immediate disposal, and all you have to do is type "google" to get there.
