GacUI: GPU Accelerated C++ User Interface


GPU Accelerated C++ User Interface, with WYSIWYG developing tools, XML supports, built-in data binding and MVVM features.

Read the LICENSE first.

  • The release of the GacUI project is put in vczh-libraries/Release.

Content of This Project

  • The Tutorial shows how to start using this marvelous GUI library.
  • The Demos section show you all demos using this GUI library.


Using this library requires you to use C++ source files directly in

All other files are for library development only.


This GUI library provides the following features:

  • Develop your GUI using pure C++, Workflow script, XML or even JavaScript (under construction).
  • Cross-platform abilities.
  • Rich control library. Container controls supports MVC and virtual list mode.
  • Control template system. You can write your own.
  • GPU acceleration.
  • XML resource supports.
    • You can use the provided GacGen.exe to generate multiple XML files with binary resources (images) into a compressed binary format.
    • This program will also generate C++ code behind for you. You can fill event handlers (but we suggest you use MVVM and Data Binding instead) in generated C++ files.
    • If you update your UI, GacGen.exe will merge your modification in C++ code and modification in XML together to generate new C++ code behind. Your update will still exist.
      • NOTE: You will see a very obvious mark USERIMPL(/* ... */) in the generated code. Here is where you want to add your code. All your modification outside of these places will be discarded on the next GacGen.exe run.
  • MVVM and Data Binding.
    • You can define interfaces that required to build your own MVVM pattern in XML and GacGen.exe will generate the C++ interface declaration for you.
    • You can also use Workflow expressions in Data Binding and statements in event handlers (instead of writing C++ code in code behind).

How to Run C/C++ in Sublime Text?

C and C++ are the most powerful programming language in the world. Most of the super fast and complex libraries and algorithms are written in C or C++. Most powerful Kernel programs are also written in C. So, there is no way to skip it.

In programming competitions, most programmers prefer to write code in C or C++. Tourist is considered the worlds top programming contestant of all ages who write code in C++.

During programming competitions, programmers prefer to use a lightweight editor to focus on coding and algorithm designing. VimSublime Text, and Notepad++ are the most common editors for us. Apart from the competition, many software developers and professionals love to use Sublime Text just because of its flexibility.

I have discussed the steps we need to complete in this blog post before running a C/C++ code in Sublime Text. We will take the inputs from an input file and print outputs to an output file without using freopen file related functions in C/C++.

Dicey Issues in C/C++

If you are familiar with C/C++then you must have come across some unusual things and if you haven’t, then you are about to. The below codes are checked twice before adding, so feel free to share this article with your friends. The following displays some of the issues:

  1. Using multiple variables in the print function
  2. Comparing Signed integer with unsigned integer
  3. Putting a semicolon at the end of the loop statement
  4. C preprocessor doesn’t need a semicolon
  5. Size of the string matters
  6. Macros and equations aren’t good friends
  7. Never compare Floating data type with double data type
  8. Arrays have a boundary
  9. Character constants are different from string literals
  10. Difference between single(=) and double(==) equal signs.

The below code generates no error since a print function can take any number of inputs but creates a mismatch with the variables. The print function is used to display characters, strings, integers, float, octal, and hexadecimal values onto the output screen. The format specifier is used to display the value of a variable.

  1. %d indicates Integer Format Specifier
  2. %f indicates Float Format Specifier
  3. %c indicates Character Format Specifier
  4. %s indicates String Format Specifier
  5. %u indicates Unsigned Integer Format Specifier
  6. %ld indicates Long Int Format Specifier

A signed integer is a 32-bit datum that encodes an integer in the range [-2147483648 to 2147483647]. An unsigned integer is a 32-bit datum that encodes a non-negative integer in the range [0 to 4294967295]. The signed integer is represented in twos-complement notation. In the below code the signed integer will be converted to the maximum unsigned integer then compared with the unsigned integer.

Using isdigit() in C/C++

In this article, we’ll take a look at using the isdigit() function in C/C++. This is a very simple way to check if any value is a digit or not. Let’s look at how to use this function, using some simple examples.

Object Oriented Programming in C++ | C++ OOPs Concepts | Learn Object Oriented C++

C++ is general purpose, compiled, object-oriented programming language and its concepts served as the basis for several other languages such as Java, Python, Ruby, Perl etc.

The goal of this course is to provide you with a working knowledge of C++. We’ll start with the basics, including syntax, operators, loops, and functions. This Course will explain you how to use data structures and create your own Functions. This Course will show you the details of the powerful object and template systems so you can create useful classes and objects.
