Dev C++ Graphics Tutorial Pdf
Computer Graphics 6 Computer graphics is an art of drawing pictures on computer screens with the help of programming. It involves computations, creation, and manipulation of data. In other words, we can say that computer graphics is a rendering tool for the generation and manipulation of images. Cathode Ray Tube. Graphics in Windows 7 or Vista. Most of the functions are two dimensional except bar3d which draws a 3d bar, you can also implement these functions using already existing algorithms. You can also use these functions in C programs. You can use these functions for developing programs in Windows 7 and Vista using Dev C compiler.
Programming with the Dev C IDE 1 Introduction to the IDE Dev-C is a full-featured Integrated Development Environment (IDE) for the C/C programming language. As similar IDEs, it offers to the programmer a simple and unified tool to edit, compile, link, and debug programs. It also provides support for the management of the. A very clear introduction to programming, and a small C tutorial. GameTutorials.com tutorials for Dev-C: C/C, Win32, OpenGL and DirectX tutorials for Dev-C. Mike Serrano's Dev-C tutorial: This tutorial will help you doing using Dev-C, as well as making graphics in console mode. Intro to C: An introduction to C for newbies. There, in 'Language standard (-std)' select 'ISO C 11': Ok that. You are now ready to compile C11! Compiling console applications To compile and run simple console applications such as those used as examples in these tutorials it is enough with opening the file with Dev-C and hit F11. As an example, try: File - New - Source File (or Ctrl+N).
-->This walkthrough shows how to create a traditional Windows desktop application in Visual Studio. The example application you'll create uses the Windows API to display 'Hello, Windows desktop!' in a window. You can use the code that you develop in this walkthrough as a pattern to create other Windows desktop applications.
The Windows API (also known as the Win32 API, Windows Desktop API, and Windows Classic API) is a C-language-based framework for creating Windows applications. It has been in existence since the 1980s and has been used to create Windows applications for decades. More advanced and easier-to-program frameworks have been built on top of the Windows API. For example, MFC, ATL, the .NET frameworks. Even the most modern Windows Runtime code for UWP and Store apps written in C++/WinRT uses the Windows API underneath. For more information about the Windows API, see Windows API Index. There are many ways to create Windows applications, but the process above was the first.
Important
For the sake of brevity, some code statements are omitted in the text. The Build the code section at the end of this document shows the complete code.
Prerequisites
A computer that runs Microsoft Windows 7 or later versions. We recommend Windows 10 for the best development experience.
A copy of Visual Studio. For information on how to download and install Visual Studio, see Install Visual Studio. When you run the installer, make sure that the Desktop development with C++ workload is checked. Don't worry if you didn't install this workload when you installed Visual Studio. You can run the installer again and install it now.
An understanding of the basics of using the Visual Studio IDE. If you've used Windows desktop apps before, you can probably keep up. For an introduction, see Visual Studio IDE feature tour.
An understanding of enough of the fundamentals of the C++ language to follow along. Don't worry, we don't do anything too complicated.

Create the code
Next, you'll learn how to create the code for a Windows desktop application in Visual Studio.
To start a Windows desktop application
Just as every C application and C++ application must have a
main
function as its starting point, every Windows desktop application must have aWinMain
function.WinMain
has the following syntax.For information about the parameters and return value of this function, see WinMain entry point.
Note
What are all those extra words, such as
CALLBACK
, orHINSTANCE
, or_In_
? The traditional Windows API uses typedefs and preprocessor macros extensively to abstract away some of the details of types and platform-specific code, such as calling conventions, __declspec declarations, and compiler pragmas. In Visual Studio, you can use the IntelliSense Quick Info feature to see what these typedefs and macros define. Hover your mouse over the word of interest, or select it and press Ctrl+K, Ctrl+I for a small pop-up window that contains the definition. For more information, see Using IntelliSense. Parameters and return types often use SAL Annotations to help you catch programming errors. For more information, see Using SAL Annotations to Reduce C/C++ Code Defects.Windows desktop programs require <windows.h>. <tchar.h> defines the
TCHAR
macro, which resolves ultimately to wchar_t if the UNICODE symbol is defined in your project, otherwise it resolves to char. If you always build with UNICODE enabled, you don't need TCHAR and can just use wchar_t directly.Along with the
WinMain
function, every Windows desktop application must also have a window-procedure function. This function is typically namedWndProc
, but you can name it whatever you like.WndProc
has the following syntax.In this function, you write code to handle messages that the application receives from Windows when events occur. For example, if a user chooses an OK button in your application, Windows will send a message to you and you can write code inside your
WndProc
function that does whatever work is appropriate. It's called handling an event. You only handle the events that are relevant for your application.For more information, see Window Procedures.
To add functionality to the WinMain function
In the
WinMain
function, you populate a structure of type WNDCLASSEX. The structure contains information about the window: the application icon, the background color of the window, the name to display in the title bar, among other things. Importantly, it contains a function pointer to your window procedure. The following example shows a typicalWNDCLASSEX
structure.For information about the fields of the structure above, see WNDCLASSEX.
Register the
WNDCLASSEX
with Windows so that it knows about your window and how to send messages to it. Use the RegisterClassEx function and pass the window class structure as an argument. The_T
macro is used because we use theTCHAR
type.Now you can create a window. Use the CreateWindow function.
This function returns an
HWND
, which is a handle to a window. A handle is somewhat like a pointer that Windows uses to keep track of open windows. For more information, see Windows Data Types.At this point, the window has been created, but we still need to tell Windows to make it visible. That's what this code does:
The displayed window doesn't have much content because you haven't yet implemented the
WndProc
function. In other words, the application isn't yet handling the messages that Windows is now sending to it.To handle the messages, we first add a message loop to listen for the messages that Windows sends. When the application receives a message, this loop dispatches it to your
WndProc
function to be handled. The message loop resembles the following code.For more information about the structures and functions in the message loop, see MSG, GetMessage, TranslateMessage, and DispatchMessage.
At this point, the
WinMain
function should resemble the following code.
To add functionality to the WndProc function
To enable the
WndProc
function to handle the messages that the application receives, implement a switch statement.One important message to handle is the WM_PAINT message. The application receives the
WM_PAINT
message when part of its displayed window must be updated. The event can occur when a user moves a window in front of your window, then moves it away again. Your application doesn't know when these events occur. Only Windows knows, so it notifies your app with aWM_PAINT
message. When the window is first displayed, all of it must be updated.To handle a
WM_PAINT
message, first call BeginPaint, then handle all the logic to lay out the text, buttons, and other controls in the window, and then call EndPaint. For the application, the logic between the beginning call and the ending call is to display the string 'Hello, Windows desktop!' in the window. In the following code, notice that the TextOut function is used to display the string.HDC
in the code is a handle to a device context, which is a data structure that Windows uses to enable your application to communicate with the graphics subsystem. TheBeginPaint
andEndPaint
functions make your application behave like a good citizen and doesn't use the device context for longer than it needs to. The functions help make the graphics subsystem is available for use by other applications.An application typically handles many other messages. For example, WM_CREATE when a window is first created, and WM_DESTROY when the window is closed. The following code shows a basic but complete
WndProc
function.
Build the code
As promised, here's the complete code for the working application.

Is there any C++ GUI API?
My answer is MANY.
There are many API's for making GUI applications.
Here are some.
1. WinAPI: (C based)(MFC is C++ based)
Its a great API and the best solution if you are windows programmer. First code will look a bit difficult, but later (after making few apps.) you will see its not so rusty. I like it, because you can do almost everything with it (in windows). The only bad thing is, that you cannot make applications for Linux with it.
Tutorial:
'>http://www.winprog.org/tutorial/index.html
2. Qt4 / Qt3 (C++ based)
This is a nice API, for making GUI applications. It works under Linux, Windows and Mac OS X. Its really easy to learn and use. But, until you dont buy licenced version, you will need to add tons of -dll s, to run your application. Qt compiler doesnt work in Vista. And, Qt4 API has a bit complicated way, to get buttons to work, if button holds some more complicated operations(actually you have to make your own SLOT's).
Tutorial:

3.GTK+ (C based)
Sorry, but I never tryed it, so Google might help you.

I also think newbies dont know for C++ IDE's. (Developing Enviroviment).
I will make a short description of some
1. Visual Studio 2005 (Visual C++)
This is a beautiful IDE for making console and win32 GUI applications. You can also compile DirectX10 or 9 projects as well. I didn't test it for compiling Qt or GTK+ applications yet.
Affcourse as a Microsoft product isn't free, but it seems to be really safe and stable IDE for Windows Applications.
I really like it, and I recommend it to everyone.
More info '>HERE
2. Code::Blocks
Great for compiling WinAPI, Qt, GTK+, WXWidgets, Ogre, D, C++ console, C console and other projects. I found some bugs, and sometimes there are problems to compile.
It's one of the best FREE IDE's.
Information and download '>HERE
3. Dev-C++
This IDE, written in Delphi is the right place for beginners. It isn't perfect and it allows you 'holes' and 'bugs' in your program.Thats why its good for beginners. VS2005 wouldnt compile most of the code, which Dev-C++ does.
Information and Download '>HERE
SOME LINUX IDE's:
-Code::Blocks
-Anjuta IDE
-QDevelop

Ah, and dont take care about all off my opinions. I prefer VS2005, but If you dont have a money, than choose Code::Blocks or Dev-C++.
I hope moderators will make this topic sticky (read me)
I hope this helps
BTW: Sorry for my grammatic mistakes.
