Ultimate++ is a C++ cross-platform rapid application development framework focused on programmers productivity. It includes a set of libraries (GUI, SQL, etc.), and an integrated development environment.

Rapid development is achieved by the smart and aggressive use of C++ rather than through fancy code generators. In this respect, U++ competes with popular scripting languages while preserving C/C++ runtime characteristics.

The U++ integrated development environment, TheIDE, introduces modular concepts to C++ programming. It features BLITZ-build technology to speedup C++ rebuilds up to 4 times, Visual designers for U++ libraries, a Topic++ system for documenting code and creating rich text resources for applications (like help and code documentation) and Assist++ - a powerful C++ code analyzer that provides features like code completion, navigation and transformation.

TheIDE can work with GCC, Clang, MinGW and Visual C++ and contains a full featured debugger. TheIDE can also be used to develop non-U++ applications.

U++ supports following platforms on the production level: Windows, macOS, GNU/Linux & FreeBSD.

• A very effective C++ library for cross-platform development in source form.
• A good integrated development environment, designed for developing large C++ applications.

You can use both, or you can use whichever you need.

U++ uses BSD license.

Main downloads:

• Latest stable release - starts download with automatic platform detection

Other downloads:

• Stable releases - all stable releases including historical ones
• Nightly build - latest unstable release of U++ (might be unstable)

More information about the framework, can be found on the official site. Don't forget to check our rich documentation.

Below is the code of trivial GUI application that displays "Hello World" string inside window:

#include <CtrlLib/CtrlLib.h>

class MyApp: public Upp::TopWindow {
public:
    MyApp()
    {
        Title("My application").Zoomable().Sizeable().SetRect(0, 0, 320, 200);
    }

    virtual void Paint(Upp::Draw& w) override
    {
        w.DrawRect(GetSize(), Upp::SWhite);
        w.DrawText(10, 10, "Hello, world!", Upp::Arial(30), Upp::Magenta);
    }
};

GUI_APP_MAIN
{
    MyApp().Run();
}

Standard part of U++ framework is integrated development environment, TheIDE.

The U++ repository is divided into several directories. The most important ones are:

• examples - exemplary codes of complex applications
• references - reference examples demonstrating individual features of U++
• uppsrc - main sources of the framework
