Some UI frameworks render everything themselves, and work based on some kind of clipping-window-within-the-host-systems-screen. Non-display aspects (such as input event handling) have to be translated to/from the host systems underlying APIs.

Some UI frameworks translate as much as possible to some underlying framework.

wxWidgets can do both. You can choose a native version (e.g. wxMSW if you're on Windows) and most wxWidgets controls will be implemented using native Windows controls. Equally, you can choose the wxUniversal version, where all controls are implemented by the wxWidgets library itself.

The trouble is that typical GUI frameworks are huge. If you want a more manageable example to imitate, you might look at FLTK. I haven't got around to studying it myself, but it has a reputation for being consise.

There are also some GUI toolkits that are specifically aimed at games programming, such as Crazy Eddies GUI. My guess - these are probably as idependent of the underlying API as possible, so that particular applications can implement the mapping to whichever underlying API they happen to target (OpenGL, DirectX, SDL, whatever) and can be the boss of the GUI rather than visa versa.

blocks|key|3849734|text|GUI框架非常依赖于windows系统，该系统规定了允许的内容以及如何创建和呈现窗口。例如，传递一个特定的选项来创建一个无边框或全屏窗口。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3849735|既然你提到了opengl和ubuntu，我猜你想从linux平台开始。您应该学习xlib，您可以在其中找到参考here。|offset|length|3849736|由于qt库是开源的，您可以下载它并查看其源代码。|3849737|entityMap|0|LINK|mutability|MUTABLE|url|http://h30097.www3.hp.com/docs/base_doc/DOCUMENTATION/V51B_ACRO_SUP/XWINSYS.PDF^0|0|1J|4|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@$D|R|E|S|1|T]]|A|$]]|$1|F|3|G|5|6|7|U|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]]]

The GUI frameworks are very dependant on a windows system, which dictates what is allowed and how windows are created and rendered. For example, pass a specific option to create a borderless or full-screen window.

Since you mentioned opengl and ubuntu, I guess you want to start on a linux platform. You should study xlib, for which you can find reference <a href="http://h30097.www3.hp.com/docs/base_doc/DOCUMENTATION/V51B_ACRO_SUP/XWINSYS.PDF" rel="nofollow">here</a>.

Since the qt library is open source, you can download it and peek into it's sources.

blocks|key|3849751|text|UI库不是从头开始开发的。它依赖于操作系统的窗口系统，该系统依赖于来自图形适配器的驱动程序，而图形适配器依赖于操作系统内核，而操作系统内核依赖于...诸若此类。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3849752|要“从头开始”开发任何软件，您可以从编写自己的BIOS开始。完成后，继续编写操作系统，然后就可以编写您想要的软件了。祝好运。|3849753|当然，这是假设你愿意作弊，并使用你不是从头开始编写的编译器。|3849754|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

A UI library isn't developed from scratch. It relies on the OS' windowing system, which relies on the driver from your graphics adapter, which relies on the OS kernel, which relies on... and so on.

To develop any software "from scratch", you can start by writing your own BIOS. Once you're done with that, move on to writing an OS, and then you should be just about ready to write the software you wanted. Good luck.

And this is assuming you're willing to cheat, of course, and use a compiler you didn't write from scratch.

Before you do that, it's worth that you spend one week on thinking: 
1, Do you really know how to do it? I doubt that. 
2, Do you really need to do it? I doubt that too.

I want to create a C++ UI framework (something like QT or like ubuntu unity Desktop)

How is programmed , is it using OpenGL or lets take plasma ui of QT (how is this programmed )?

Direct answers , reference links anything will be helpful.
