Known Problems and Future Plans

---

General Issues

• Toolkits can be characterized as having a "ceiling" (what can be done [easily] with them) and a "threshold" (how hard it is to get started with simple things). Work on subArctic thus far has concentrated on creating highly extensible infrastructure -- a very high ceiling. Work will now turn to lowering the threshold of the toolkit.
• There are currently too many interactor classes and not enough class organization. Interactors need to be merged into larger (parameterized) objects, organized better, and/or split into new packages.

Specific Known problems (in no particular order)

• Additional constructors with fewer arguments are needed in some places (i.e., without an initial size and/or position for interactors that will be constrained).
• Need async_image class.
• Enable/disable of interactors doesn't provide proper feedback (but does enable/disable input).
• A number of platform difference problems (and platform specific bugs) need to be resolved

Specific Plans (in no particular order)

• Fix problems above.
• Build SLEDDOG (the Sophisticated Layout Editor and Dialog Object Generator, AKA a constraint-based interface builder). This will allow the layout of many (most?) interfaces to be "drawn" rather than coded.
• Add more example code for tutorial purposes.
• Add a new agent for "multi-click" interactions (including one for interactors that need to get both click and double-click).
• Add new infrastructure to provide automated socket support inside subArctic.
• Finish the multi-line, multi-font text edit interactor.
