Since its launch in 2008, the Fermi Large Area Telescope (LAT) allowed us to peek into extremely energetic side of Universe with unprecedented sensitivity and resolution. The tools available for analyzing Fermi-LAT data are Fermitools Fermipy, both which can be scripted Python run via command lines a terminal or web-based interactive computing platforms. In this work, we providing community eas...

Graphical user interfaces have become very popular for database systems since they increase the usability of these applications. The functionality and ease-of-use of the graphical user interface, however, depend on the expressiveness and complexity of the underlying data model. With the advent of new database technology based on powerful data models like the object-oriented data model new chall...

Object-oriented frameworks can be complex and diicult to use. Tool support can greatly aid developers in using these frameworks. However, existing tools, such as graphical user interface builders, only support one framework and are not easily customized. Hooks, which describe the intended use of a framework, can form the basis of a general, exible tool that supports many diierent frameworks. Th...

Layout managers are used to control the placement of widgets in graphical user interfaces (GUIs). Constraint-based layout managers are more powerful than other ones. However, they are also more complex and their layouts are prone to problems that usually require direct editing of constraints. Today, designers commonly use GUI builders to specify GUIs. The complexities of traditional approaches ...
