GUI-Toolkit für Hollywood: erste Demo-Version des plattformunabhängigen HGui
HGui ist ein mit Hollywood entwickeltes GUI-System, das im Gegensatz zum Amiga-spezifischen MUI Royale für alle von Hollywood unterstützten Plattformen verfügbar wäre. Die Entwicklung sei weitgehend abgeschlossen, ein erstes Demo steht jetzt zur Verfügung (Download-Seite).
Der Autor Fabio "Allanon" Falcucci denkt nach eigenen Angaben über eine kommerzielle Veröffentlichung nach. Sinn der Demo-Veröffentlichung ist es, zu dieser Frage etwas Feedback einzuholen. Bei entsprechender finanzieller Unterstützung stellt Falcucci Tutorials und "umfassenden Entwickler-Dokumentation" in Aussicht.
Geplant sind zwei verschiedene Veröffentlichungen: Zum einen als fertig kompiliertes Applet, zum anderen als Quelltext. Beide Varianten würden mit Tutorials und Entwicklerdokumentation ausgeliefert. Den aktuellen Entwicklungsstand beschreibt der Autor als "stabil und benutzbar". Es seien noch einige kleinere Fehler zu beseitigen, außerdem fehlten noch einige der geplanten Eigenschaften.
Die Eigenschaften seines GUI-Toolkits beschreibt Falcucci wie folgt:
General features
- Object Oriented Programming
- Flexible and multi-layered skin system
- Easy of use
- Fast
- Scalable (tuning the cache system and the theme)
- Since HGui does not depend on any system specific command/library all developed projects can be compiled for any system supported by Hollywood, your GUIs will be the same on every platform, exactly the same.

Layout system
- Gadgets can be arranged using the MUI concept, you define some gadgets that will be grouped inside another gadget, this way your GUI is represented by a tree where the tree root is a special gadget called 'rootGadget' already created for you when a window is created.
- Supported layout are:
- When you define child gadgets you can define the following properties:
- Gadget weights (percentual variable, percentual fixed, pixel variable, pixel fixed)
- Borders (top, bottom, left, right) from the father gadget
- Gap between childs in pixel
What's missing/needs more love
