Para usuários da Hwgui, pouca diferença na sintaxe.

It's a framework for Android, a tool designed to write in Harbour applications for Android based devices - just as HwGUI allows you to write in Harbour GUI applications for Windows and Linux. I even thought about it first, as about HwGUI for Android, but along the way decided that it is better to refuse from thoughts to provide compatibility on prg level with applications on other operating systems - too specific is and the Android platform, and it interface, and the nature of the devices that use Android. Take the size of mobile devices, which is unlikely to significantly change as technological advances - just add a normal keyboard, or double the size of the screen - and the device will simply cease to be mobile. Now, imagine how any familiar desktop application with a bunch of widgets will look at this device ... It is clear that the interface of the application will have to be rewritten to suit the standards of mobile devices. And if so, why should we care about full compatibility with GUI libraries for Windows and Linux ? Application code that uses HDroidGUI, in the part which is responsible for the interface will be different from the code of HwGUI applications, although I try to use the most similar syntax.
