SWT/Qt – Overview

  Motivation

 Demo  Questions

2


SWT/Qt - Motivation

  Building SWT based Applications with Riena

  Riena has Look and Feel (Colors, Fonts, Rendering)

  Riena LnF is limited by SWT‘s options

  SWT is a very thin layer on top of OS widgets

  We wanted more control over the styling of widgets

  Predecessor of Riena is Swing based

  Extremly good feedback from customers

SWT/Qt – Investigations on the way…

  Styling is important   Look of widgets (gradients, scrollbars)

  Central styling for all UI components

  Investigated   SWT on Swing

  SWT and Flex ?

  E4 CSS Styling   platform independant styling   limited to the abilities of the current SWT API

7


SWT/Qt – the implementation

  SWT on Qt

  Qt native versus QtJambi

  CSS is toolkit dependant and not independant

  CSS is applied to toolkit and not interpreted by SWT

  Qt is available on all major platforms but not a „native“ implementation as Win32, GTK or Cocoa
