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

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
