28 What's about......a Change of Paradigm? Take the RISC!

29 What are the basic elements that any user interface can be built with?

30 1. Rectangles - with/without text - with/without background styling 2. Textinput - single line - multi line (3. Graphics) What are the basic elements which of even complex user interfaces?...and the possibility to A. position them absolutely (x,y,width,height(,z)) B. compose them

37 RISC Browser Architecture ADVANTAGES UI Element Library Based On Nucleus Elements Browser Incompatibility is no issue. Nucleus Library #... Browser compatibiliy by design! And not: browser compatibility by test... Performance on current browsers (JavaScript Compilers ) is excellent. Layouting is not bound to HTML limits.

42 JavaFX - Summary Gut zu programmieren (Ausreichend) Stabil Performance: befriedigend bis ausreichend ;-) Deployment: setup.exe

43 JavaFX passt - Szenarien Viel Client-seitige Logik Java > JavaScript Client-seitiger Zugriff auf Resourcen File System, serielle Schnittstelle, TCP/IP Explizite Unabhängigkeit vom Browser Interaktion auf Pixel-Ebene

44

45 JavaFX für Unternehmensanwendungen Schwierig zu positionieren Kein Mainstream Keine Zero Installation Keine Pixel-Interaktion Einfach so einsetzen ist nicht möglich, Sie brauchen einen echten Grund! ;-) Java ist für bestimmte Szenarien ein guter Grund

46 JavaFX für Unternehmensanwendungen CaptainCasa Sicht RISC HTML Ansatz löst die Probleme, die wir mit JavaFX hatten JavaFX Positionierung ist/wird deutlich geringer

47 Im Jahr 2016, mit RISC based HTML

48 Im Jahre 2016 JAVA FX JAVA Swing RISC HTML ;-)

49 JavaFX Swing HTML V. CaptainCasa Enterprise Client

50 Take the RISC! reduced instruction set client A substantially different architecture for industry-stable HTML Web UIs. browser-compatible by design fast by design robust by design zero installation zero maintenance
