user interface - How does Qt only use C++ to make custom GUIs for some many platforms? -


I do not think how low level graphics works, to see / feel for its own custom GUI Does each platform use every platform API or something? I will ask because I am really thinking how to create a custom GUI application with a custom graphic form, how can I go about creating my own structure?

"How QT uses C ++ only to create custom GUI for several platforms ? "

"Does this use every platform API ...?"

You answered your question and created a general library to write your applications with the developers. Application developers write their applications only once, do not pay attention to the platform specific. After this, the library author shows different versions of the library for each platform, which handles all the specific UI calls. It is called Encapsulation:

If you want to write your own such library, then you have to find out what is common or what is known in all the platforms you have targeted High-level concepts will require your application, and will create that intuition. After this, apply that abstract to support each platform.

Edit:

Also note Juliano's comment It seems that rather than what you have asked, what you want to do, It can be close to it.

If I can possibly escape from it, then I will not work for trolltech or wxdwdgates team or people of GTK or mono people.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
