I'm developing my first Windows desktop application and I'm trying to figure out what the best approach would be to create the program's GUI.
I know, I know... I feel stupid for asking considering the amount of data on the subject on SO. However most answers seem outdated and I'm not sure if they fit my specific project. Also tutorials for Windows 8 'metro apps' are clogging my Google search results, which is NOT what I'm looking for.
I use Visual Studio. I've followed tutorials. I have basic knowledge of C and Java and extensive experience with PHP. I'm excited to learn C++, so I'm not looking for GUIs to create a GUI (like WinForms). I also don't care about managed code and portability for now, especially since I'm trying to avoid dependencies (i.e. users having to install .NET). As long as it runs smoothly on Vista and up, I'm happy.
The application
The software will teach basic physics to kids. I'd like to create a main area and a sidebar. The main area will feature a physics animation, say a bouncing ball, along with some Q&A. Users can zoom in to the animation to measure some stuff and answer the question. Users can track their progress in the sidebar. That's pretty much it.
What I've found so far
I'm getting a bit frustrated with MSDN. Most of their examples are given in four different languages (C#, C++, etc). I can't seem to get more than a bit of Hello World code from them.
I found a GDI API on MSDN and it seems like a good start for me. However I've read quite a few answers on SO saying creating layouts in pure C++ is really hard, that we're better of using frameworks like ATL and WTL. Since I'm also going to create (somewhat interactive) animations, I've wondered whether I should use gaming-targeted APIs like Direct2D.
Since all of this is new to me, and there are a lot of options, I don't know where to start for my particular application. Any tips would be greatly appreciated!
Using the raw Win32 API (no additional downloads or third-party helpers):
Here's a good primer (introduces dialog boxes, text boxes, buttons, etc): theForger's Win32 API Tutorial
And here's where you go from there (numeric up-downs, list boxes, combo boxes, tooltips, and more): Common Controls on MSDN. Most of these require you to #include <commctrl.h>.
I also found this to be a good resource that covered what the other two didn't: Win32 Developer - Window Assets
But the Win32 API doesn't seem like it does exactly what you want. A physics app for kids should have a more visual GUI than the API can provide. Good luck, though!
If you're ok with adding additional Frameworks, I'd suggest looking at Qt.
It allows to create the GUI from code only, has a good structure, and has an Interface for 2D drawing, if required.
If you are concerned about dependencies, you only have to include the Qt DLLs to your executables; no installation is required for the user.
To get started, see my (old) tutorial "Lessons in Windows API Programming".
But you really need a good book, such as edition 5 or earlier of Charles Petzold's classic "Programming Windows".
The problem with latest edition is that it's for C# and .NET, with Charles grabbing the tail of the "new way" at just the wrong time…
Disclaimer: I haven't checked the details of edition numbers.
Using the Windows API is the simplest, but producing advanced GUIs can take a very long time. Microsoft Foundation Class is a way to make the Windows API more user friendly and OOP. Does anyone have any experience with MFC?
Why not use some 2D C++ game engine, like HGE: http://hge.relishgames.com/overview.html.

I have recently read MFC Internals (ISBN 9780201407211) and it helped me greatly gain an intimate understanding of how MFC works and increased productivity about 100 fold. I was wondering now that I am into Qt, is there any book or documentation out there like this? I have been having a hard time finding straight-up documentation on Qt, it always seems to be beat-around=the-bush style of documentation (they tell you how to build the house, but not how to cut down the tree) ??
The best way is to try developing your own application. Just start from a basic application like calculator. Add a few widgets to it and code it as you go. For reference use "C++ gui programming with Qt4" mentioned by Zlatomir. I have recently designed a whole GUI using Qt. I drew its screenshots on Inkscape to get a prototype look and afterwards I started working on designer to fulfill each functionality. Then I implemented the code and I repeated the designing and coding steps. Also, the best help will be Qt Assistant - its sufficiently complete, no Internet required so save times and simple to use. Going my way, you will not only learn Qt in short interval after which you can go through the book to know what tips and tricks you might not know, but also it will be interesting so that you may not give up like many others who just fall midway through the reading part. Warning - Doing this way, you will also know about pitfalls/drawbacks of Qt and how to not go that way.
This is one of the links I found last night. I went through 2 pages and found it might make your life a bit easier - http://zetcode.com/gui/qt4/
I have not read the MFC book you mentioned, but the Qt framework i learned by reading from "C++ gui programming with Qt4" (the first edition is available as a free download) and "Foundation of Qt development" and also it's worth mentioning this documentation page, that contains links to the basic concepts of Qt framework.
I'm not very familiar with Linux, but have some experience with C and C++. I would like to get in touch with some Visual FX and/or UI development (either C or C++). I was wondering if there is a possibility to access the GUI elements of the Desktop on Ubuntu's Unity UI.
What I especially would like to do, is to render animations on the desktop or windows or all over the screen. (particle effects when clicking with the mouse or so).
Can anyone point me in the right direction? (Libraries, Documents, ...)
I think Desktop Effects have to be designed specific for the corresponding Window Manager.
I think unity uses (some sort of) compiz, so you should look into compiz plugin development.
A lot of "i thinks" so i am not really sure if that'll help you, but good luck.
You want to learn a lot more about GTK. There are lot of documentation on line (and some books also). You might code in C++ using GtkMM (but you could consider Qt also). GTK itself is coded in C, with well designed coding style and convention. Looking inside its source code is worthwhile.
Is Qt an interesting platform for business apps development, outside of Nokia phones ?
Why ? Strong points ?
Thanks
I like Qt because:
Very well-designed framework, e.g. signal-slot, model-view, graphics view/scene/item/proxy, painter/paint device/paint engine..., too many to be listed here!
Excellent documentation!
Cross platform language/API, as well as tools like UI designer, creator, and so on.
Rich features, e.g. graphics framework, network library, database engine, and so on.
Active community, and active development.
There should be more. If you have ever used it, you'll find it's easy to build your framework upon Qt.
I didn't have any complain to Qt. If I have to say at least one disadvantage here, "convention". You must adopt the convention of Qt, e.g. You have to use moc to make the meta object of your objects, and it's easier for developers to use Qt's vector, list, auto_ptr than STL, tr1. But I never found any issue caused by that. On the contrary, it works very well.
In my opinion, Qt is the state-of-the-art C++ framework in this modern world!
P.S. There are a lot of commercial applications built on Qt. You can find it under Qt's official website. But I'd like add one more here: Perforce, one of the top commercial source code management tools, built its client tool on Qt for Windows/Linux/Mac.
yes it is .. just look at kde apps :)
or see more applications made by qt
and it has alot of bindings in many languages
Documentation
cross-Platform IDE
further reading
may be this is not so related to the question ... but my first deal with qt was just great starting from their well organized Documentation to their great widgets
the GraphicsView is just ammazing ! :)
It's about the only current/modern C++ gui library on Windows.
MFC is so old you have to write comments in Latin
WTL would be nice if they had finished it before abandoning it.
Winforms/WPF + managed C++/CLR - all the fun of several incompatible new technologies at once.
Bad points:
To fit on lots of platforms they have invented their own solutions to things that are now in the STL/Boost
The signal/slot mechanism - tricky to debug and silently fails (with no error) with simple typos.
Although everything is possible it's sometimes a lot of effort to do simple things (they do love MVC) compared to Winforms.
Qt is simple
Qt is powerful
Qt is NATIVELY-CROSS-PLATFORM
Qt is REALLY-CROSS-PLATFORM
Qt is comprehensive (but the Media side of it still needs to grow)
Qt doesn't require Garbage Collection, but it embeds a GREAT model of memory management that makes you forget about memory deallocation
Qt is solid
Qt is modern
Qt proposes some new paradigm of programming that are really good (Signals-Slots)
Qt runs a lot of VERY successful software: (Skype, Google Earth...)
Are those points strong enough?
Maybe you have heard about Google Earth which happens to be programmed in Qt too.
That aside, I like Qt for my in-house development because it
is very well supported and documented,
allows me to write simple and decent-looking apps that are
works cross-platform for Windows and Linux with little effort, and
contains nice to have components for database access, regexps, guis, xml, ...
I also use the Qwt widgets for easy real-time plotting on top of Qt.
I really dont understand whats the point in underestimating tools/frameworks which makes things easy for programmers. Qt is too good for GUI development, I would say its much better than any current existing crossplatform app development suite.
So many advantages, I have been using it for more than three years now for a product to be deployed in Linux/Win environments. The app is thread intensive and initially we had a tough time using pthreads and its conterpart for windows. Then we switched to Qt(and QThreads eventually) and things were a breeze...
Backed by active development, a highly helpful and supportive community along with excellent documentation, training, certification programs, videos, forums... its easy, fast and effective to develop in Qt. You should see the video which they create a web browser in just five mins!
Its really 'cross platform', and it doesnt have a software wrapper(like Java does) to enable this which makes it faster. Cmon, we all know java apps have buttons which takes a second to respond to even a simple 'click'.
I hope Qt will someday do a take on Java. :D
after all, 350000 developers cant be wrong when they chose Qt.
Pixar uses Qt (or at least, used, as of 2005) internally for certain parts of their tool suite (called "Marionette" in the marketing) collectively called Menv, ("men-vee" for Modelling ENVironment)---at least for their lighting sub-tool Lumos.
I'm learning programing windows applications with C++. Now I'm reading about messages and I'm playing with the spy++.
What function spy++ use in order to mark/highlight the window under mouse cursor?
Also, can you give me some tips about using MSDN? I'm my opinion is not user friendly at all.
I'm learning programming by myself and i can't get some real life experience tips as those which are learning at college or in teams.

Not sure exactly what your problem with MSDN is ... I tend to go to e.g. Win32 and COM development and look around for a suitable category in the listing to the left, then click down from there. Or just enter function names and search if I already know what I'm looking for but want the reference documentation. On the other hand, I'm not much of a Win32 developer.
I think spy++ is just inverting the colors directly on the window/screen DC (You could use InvertRect() for example) On Windows 2000 and later, it is probably better to use a translucent layered window if you actually wanted to implement this window highlight since some graphic corruption can occur when messing with other windows behind their back.
Writing a Windows application with just the windows API is possible, but you'll end up writing huge amounts of boilerplate code just to create simple things. This is why people normally use libraries built on top of it to make things easier - MFC for example.
The MSDN article Creating Win32 Applications provides a good explanation of the ins-and-outs of a Windows application using the Win32 API. Bare in mind though that you could build the same application in minutes using MFC.
I agree that MSDN is not the most user friendly source of information for a beginner. In my opinion it works much better as a reference.
My advice would be to focus on building some test applications using MFC (assuming you are tied to C++ as a language). Try looking at the codeproject MFC sections for example, and perhaps even buy a book to help get you started. This does of course require Visual Studio, but you can download the free express edition here
I am new to c# and VS, but I am getting it. The application is this: A program in which the end result will draw a spider from options in which the user will define. Lets say there are 100s of options: size and number of body parts, color, connections points to the body, etc.
First question: Should I try to use the library included with VS 2005? Or, is there another environment in which I could "tap into" to get good results (flash, java, etc.)?
Second Question: Could you direct me to information corresponding to your answer from the first question?
Thanks so much, the kids I teach will love it!

Hmm.
This is truly a rough question, not because I don't know how to do it, but because it can often be so ridiculously daunting for beginners. If you use the "standard" Windows Forms C# method of doing it, you'll end up asking yourself, "What the #*(&! is WM_PAINT?" or "Why does my program totally get messed up when I move a window over my picture?!"
There are basically two main technologies that you can use to do drawing in .NET : Windows Forms (what MusiGenesis suggested) and WPF, or Windows Presentation Foundation, which ships with the 3.0 version of Visual Studio. That means that if you download the .NET 3.5 SDK or use Visual Studio 2008, WPF comes with it.
I'd recommend using WPF instead of Windows forms if you're just starting off, because the dirty details of drawing and repainting are largely abstracted. You can also define a lot of your picture as markup, just like a web page, and then manipulate it in code. Good luck and have fun!
Here is a link to some examples of how to draw things with C#:
http://www.geekpedia.com/tutorial50_Drawing-with-Csharp.html
This example uses just the built-in graphics methods of .NET, so you won't need any other libraries.
