Ultimate++,[3][4][5] also known as U++ and Upp - is a C++ rapid application development framework which aims to reduce the code complexity of typical desktop applications by extensively exploiting C++ features. Programs created with it can work on multiple operating systems and hardware architectures without the need to write platform specific code.

It possesses its own integrated development environment called TheIDE[6] that are designed to handle all library features.


The major Ultimate++ features are:

Hello World[edit]

The following example creates a C++ application with "Hello world!" button:

#include <CtrlLib/CtrlLib.h>

using namespace Upp;

class MyApp : public TopWindow 
        Title("Hello world");
        button.SetLabel("Hello world!");
        button << [=] {
            if (PromptYesNo("Button was clicked. Do you want to quit?"))
        Add(button.HSizePos(100, 100).VSizePos(100, 100));
    Button button;
