Ultimate++

From Seo Wiki - Search Engine Optimization and Programming Languages

Ultimate++^{[1][2][3][4][5][6][7]} is a C++ cross-platform development framework which aims to reduce the code complexity of typical desktop applications by extensively exploiting C++ features.

[edit] Features

• currently supports Microsoft Windows, Linux/X11 and BSD/X11.
• includes an IDE and a GUI designer.
• uses the free BSD license.
• uses heavily RAII and auto pointers-like mechanisms to avoid manual memory management and even to limit the use of pointers in the code ^[8]
• can emulate^[9] native widgets look and feel. On X11 systems, Ultimate++ supports gtk widgets look and feel.
• numerous reference examples are provided.
• standard distribution comes with ultimate++ sources included, even the IDE ones.
• uses NTL^[10] as template system instead of STL

[edit] Hello World

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

#include <CtrlLib/CtrlLib.h>
 
using namespace Upp;
 
class MyApp : public TopWindow {
	Button button;
 
	void Click() {
		if(PromptYesNo("Button was clicked. Do you want to quit?"))
			Break();
	}
 
	typedef MyApp CLASSNAME;
 
public:
	MyApp() {
		Title("Hello world");
		button.SetLabel("Hello world!");
		button <<= THISBACK(Click);
		Add(button.HSizePos(100, 100).VSizePos(100, 100));
	}
};
 
GUI_APP_MAIN
{
	MyApp().Run();
}

[edit] Criticism

• it doesn't use the Standard Template Library (STL)
• NTL template system semantics are difficult to understand at first since assignment operator in reality gets overloaded to perform a move ^[11]operation and not a copy. This is done for performance reasons and to overcome some STL limitations, but new C++0x standard should enable even STL users to perform move operations with classes by introducing the operator &&.
• since many C++ operators are overloaded to perform common tasks such as assigning callbacks, understanding the code can be a difficult at first
• there are no layouts handlers for widgets, although Ultimate++ has a system of logic coordinates to maintain relative coordinates of objects when resizing windows. Having three buttons properly aligned and resized on a row without layout managers still remains difficult, though.
• Ultimate++ IDE support for languages other than C++ is very limited. It provides some syntax coloring for SQL and little else.

[edit] Software built on Ultimate++

• AWS Truewind openWind - an open-source wind farm design software
• Gastronomie Kontroll System, a point of sale system for restaurants
• WebMap, GIS application
