Implementation behavior

The problem with GUI programming using C + + is that the level of most libraries is too low to put too much burden on programmers. These libraries rely on structures similar to the C language, or their wrapper classes cannot hide enough complexity. Also, they don't make event programming simple enough, forcing you to understand the basics of WM_ messages.

In this article, I'll introduce you to egui++, a C + + library I wrote to provide you (client programmers) with a high-level interface for handling GUI applications. It can hide complexity, making event programming fairly straightforward by completely hiding the knowledge of WM_ messages. You don't have to deal with any original structure like C, and you always just need to work with classes. In summary, egui++ client code is easy to read and easy to write.

egui++ only runs in Windows®. I really don't trust cross-platform GUI applications unless they are not important (just simpler test frameworks, prototypes) or just for teaching purposes. More importantly, I really think we should make good use of all the features provided by the underlying operating system. Windows XP and Windows vista® do offer a number of features.

Both native and portable

For those who expect to use CLR code, you have mastered C + +. That's a good platform, so there's no need to improve it. The rest of you are eager to use a good library for Windows 2000 and the updated operating system to raw machine Windows code, please continue reading. You will be satisfied with the results; The library leverages your target operating system and is intuitive to use. And you don't need to use the Microsoft®.net Framework at all. The code you write is used like C + + code. In addition, you will write code that is not specific to the Visual C + + compiler. If you prefer, you can use g++ (GNU C + + compiler) 4.1 to compile your own code. Basically, if you encapsulate Win32®api, there's nothing to prevent you from writing portable code.

That is, for important GUIs, you need a good IDE, such as visual studio®2005 or Visual Studio 2008 Express Edition. I've tuned my library to integrate with the Visual Studio Express and newer versions to provide you with a better GUI experience. What I really value is code completion to ensure that the IDE tries to help when you create a new GUI class or extend an existing GUI class.

I want to enjoy the process of writing GUI applications. Therefore, I created the egui++ to make GUI code easy to read and write. For example, I have implemented code completion in all possible places. This way, GUI programming is safe (if there is an error, I will catch it at compile time whenever possible; otherwise, a Run-time exception will be thrown). egui++ is appropriate for the resource editor (which is integrated with the updated version of Visual Studio 2005 and the Resource Editor).
