UIa is a cross-platform and cross-library framework for Java. It is designed to make it easy to create the graphical aspects of an application.
UIa is built on top of a native graphics library or a third-party graphical framework.
To achieve the cross-platform goal, the UIa core has been designed to be highly adaptive.
Currently, its core is structured as follows:
Two interfaces are the fundamentals of UIa:
- Context: is the framework basement and has the responsibility to manage the window frame and handle a single View;
- View: is the basement for every widget created with UIa.
Migrating a project between two platforms is easy, all you need to do is implement the right Context for the target platform and use it as application basement. A desktop Context implementation, based on the Java AWT, has been already provided. If you have other needs, try experimenting with creating your own custom Context implementation.
The following part shows a 'hello world' application made with UIa. It displays a view on the left and, when the user clicks on it, a popup appears or disappears on the right.
