Christian Campo ESE 2010 – Nov

SWT/Qt

Copyright © 2010 compeople AG, Made available under the Eclipse Public License v 1.0

SWT/Qt – What happened until now ?

  Start Implementation by compeople in May 2009

  Talk ESE 2009

  Talk ECon 2010

  Talks with Platform Team to make it part of SWT

  SWT/Qt code checked into eclipse.org (CQ 4301)

  dependencies QtJambi + Qt cannot be at eclipse.org

  Move to Eclipselabs.org (Bugzilla 318484)

SWT/Qt – Our 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

Building a SWT Platform

  All SWT Platforms are more less RE-implementations (no interfaces, some common classes)

  SWT is Java Code using JNI to call the respective toolkit

  SWT Java implementations contain low level properties (handles, pointers etc.) which are public

  SWT/Qt (similar to Cocoa) is build on of an OO-API

  SWT/Qt has no public properties of internal properties

  Building your own implementation is an adventure

  You learn a lot about SWT

6


CSS styling

  SWT/Qt uses the CSS styling of Qt   CSS styling directly on any widget or globally for an application   CSS styling can be changed any time at runtime   CSS styling can be reset

  CSS styling if set at runtime might overwrite program settings (i.e. background etc.)

  CSS styling in SWT/Qt is the same concept as e4/CSS. (e4‘s CSS implementation is currently limited)

SWT/Qt – the implementation

  Another interesting aspect is having a „native“ Eclipse IDE on Qt based systems (KDE)

  The current implementation can run the Eclipse IDE but is not optimized for speed yet.

  Discussion on Bug 318484 about SWT/Qt should rather by based on Qt directly (using a handwritten replacement for QtJambi)

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

  SWT/Qt is not feature complete i.e. no Drag and Drop support
