UML-like architecture tool. QT project heavily using QGraphicsItem.

The user can enter a list of classes, base-classes, class-members, and class-description. This list can be very long, and heavily linked. Classes may be grouped in different collections, whereas each collection has it's own color-style. The ggClassyArchitect does not show ALL of the classes and ALL its connections by default in its view, but the user can select a set of classes for visualisation. The same class can be visualized with multiple class-boxes in the same view. The viewer displays only the shortest connection lines (this allows to draw charts with less tangled connections). Multiple views based on the same set of classes can be created, showing different aspects of an architecture. Class properties can be edited interactively within the view.

• As simple and powerful as Google Drawings
• With fully automatic connection lines between classes and members
• Collections of classes with same color-style

• Docking Tool-Bar (list classes, add/delete classes, add/delete class-boxes)
• Class-Box: edit members, and member-class-names
• Edit base-classes (interactive, with rubber-band-path)
• Hilight class-boxes which display the same class, depending on selection
• Interactive delete Class-Box (just the box and not the class, "x" on top right)
• Docking Tool-Bar (collections, edit colors and fonts, line-styles)
• Multiple views (different sets of class-boxes)
• Frames (rectangular free-hand boxes for visually grouping class-boxes)
• Docking Tool-Bar (frames color properties)
• Menu with default preferences (for new class-boxes, or frames)
• Remember recent window position, file-dialog folder
• Menu with recent file list
• Menu with undo/redo
• etc.
