The Ptidej Tool Suite includes a graphic framework to build different types of viewers. The viewers are independent of the underlying graphic frameworks, be there AWT or SWT. In the Ptidej UI project are all the interfaces and classes allowing the viewers to be independent of the graphic framework and to put in one place most of the common code. (There is still duplicated code here and there, it should disappear as time goes by…)
In the Ptidej UI project are :
ptidej.ui.IDrawable that any graphical objects must implement.ptidej.ui.canvas.Canvas that implements a graphic framework-independent canvas.ptidej.ui.kernel.builder.Builder that provides a default implementation of the builder to create a graphic model from a PADL model. This class can be sub-classed by other implementations to fine-tune the graphic model and to handle new constituents. A typical example is the builder defined in Ptidej UI Analyses to colour constituents that have been removed between two models.ptidej.ui.kernel that provides a set of graphic objects that matches the constituents of any PADL models.ptidej.ui.occurrence that provides a default implementation of the graphic objects to display occurrences of motifs (any motifs!).
