GUI Programming

Hello to all,
Sorry for the newbe question but I never experienced in that.

How do i combine my code with a GUI in ,say, visual studio 2005.
I only know how to write "school code" to a console.
How can I make my code more - real like, and move it into user interface
for better functionality.

Thnx alot.

You'll need to work through some tutorial examples on GUI programming.

Combining an existing console application with GUI is a redesign of the application.

The key unique feature of GUI over console programming is that GUI applications are constructed as a set of responses to events, whereas console applications assume a starting point, run through a series of operations, then exit. GUI applications start up, then wait for events to occur, which can occur in any order (keystrokes, mouse moves, button clicks, etc).

The subject is too large to engage in posts here. You'll have to find tutorials for your compiler/framework that walk you through the concepts, and come back here with questions on more specific tasks.

Google or search around here for GUI tutorial, GUI example, Windows tutorial, MFC tutorial (if you have MFC), WTL tutorial (if you get WTL), wxWidgets tutorial (if you'd like to make linux GUI apps) - see where you go from there.

Thank you Jvene,
I tried finding good tutorials pre posting
but could not find any decent ones that I can actually learn from

I will how ever try to find something

Which framework are you favoring, MFC, WTL or others?

Sorry for the late reply, I could not get to my PC for a long time

I have no favorite Framework, what ever is your favorite will also be mine,
just tell how to use either.

thank you very much.

Then you could start with MFC ;)

Tutorial

But I suggest to get an mfc book ... that would be more helpful than a tutorial . ( IMHO )

Good luck.

Thank you very much gili

It's not a professional question but where are you from
I meen world wide?

Well if you read my profile you will find it ;)) :D .

Hey that's great I am also a Romanian in origin.
My father Came from Romania.
and my girlfriend is also Romanian .

very nice to meet you

Hello,
My question is whether making the GIU using only the Win32 API is an overkill, or it is quite normal? Should one definetly use MFC, or some other GUI library?
How do you guys create GUIs?

Hey stormdev:

The question hinges somewhat on the nature of C vs C++. I say that because the Win32 API, and the general approach to design of a GUI application based on only Win32API calls, is generally a C implementation.

If, say, one began immediately to apply C++ concepts to the design of a GUI application that was started out based only on the win32 API, eventually you would end up encapsulating most of the concepts into C++ objects. The result, if taken to logical extension, would be a framework something along the lines of MFC, wxWidgets, QT, WTL - or any of the others.

While for the sake of a single application, the resulting 'framework' you'd create would be small, limited to those features of interest to you in that one application, the purpose of bothering with objects is, among other factors, the ability to reuse code made to solve generic design goals like creating windows, handling files, dealing with resource, painting, etc.

Most engineers agree that C++ provides leverage, and therefore by extension so do the frameworks, depending on their quality and suitability toward your application goals.

In my case, I focus on cross platform application development, which means I want one body of code (as much as possible) to compile and work on Linux, Windows and Mac (sometimes Palm, hand helds, smart phones, whatever).

By abstracting the concepts common to all GUI's (that of the windows, dialogs, buttons, menus, events, etc) - a framework can offer a developer the option of creating cross platform GUI applications that is otherwise impracticable in C.

It may be possible in C, but the amount of work involved in write GUI code in C that's "not win32", not "Linux" and not "MAC" - but generic to all 3 - is tough enough to try it without the leverage of object design.

There are still developers writing in C for these GUI applications. Most will identify the size of the executable, or the sense of speed. There was a time with that imperative was more important, but I think that time was gone by the era of 128Mbyte RAM desktops and laptops, around the time of 400Mhz CPU's.

There are lots of options and considerations that go into an application's engineering, so I can't say that a given framework is an obvious choice for most applications. I use wxWidgets frequently, but I've had little trouble using MFC, WTL, Borland's OWL (back when OS/2 seemed to matter), and others.

You ask, also, in an era of .NET application design, and that's an entirely 'other' area. With respect to win32 applications, and Linux and MAC, the operating system is exposed as a set of functions. The C++ frameworks like MFC offer leverage, to varying degrees of quality, that give leverage to developers writing to those targets. It's the object level exposure presented by the framework that the programmer uses to implement the app.

In .NET, the operating system is exposed to the application programmer as a set of .NET objects. This obviates the need for a framework to some degree, and offers the leverage of objects at a 'native' level. The degree to which this is a 'good' thing is related to the quality of the .NET object design. So far many find it wonderful. Writing for it is not yet recognizably portable outside of Windows, though progress in that direction is moving.

See Dude it's Depend on person to Person .if you are using Win32 you have to Perform a lots of calculation by your Self. But in case of MFC or ATL Everything is there what i mean to say mostly classes supported for GUI development so easily you can Proceed . But before Proceeding to next Step it is always good that atleast you have some basic idea about your first step then only you can understand how your program flow. One more important Thing some programmer also like to take help of OpenGl and DirectX to develop Their GUI application for more detail or to learn OpenGL or DirectX your can browse on GOOgle .

Thanx
