Qtopia - 4.0.0-EAR Release Notes


The Qtopia 4.0.0 Early Access release provides a preview of the Qtopia Platform 4.0. The API is considered relatively stable, however, some changes will be made prior to the final release. Foreseen changes to the API are listed in these release notes. The Early Access Release is not indicative of the performance or quality of the final release.


  1. Addressbook:
  2. SpeedDial (settings program): now uses a unified interface for both touch-screen and keypad modes.
  3. QThumbnail: A new class QThumbnail has been added to the Qtopia library to replace and make public, the internal Image class in Qtopia 2.x. It allows generation of thumbnails of large images with added efficiency for JPEG images. That is, for JPEG images there is no need to load/decode/scale and entire image to produce a thumbnail.
  4. QSound:

    Previously once a Sound is played it will continue to play through after destruction. QSound however will stop playing at destruction. To ensure the whole sound is played make sure the life of the object is longer than the sound.

  5. The APIs of QDocumentSelector and QImageDocumentSelector (previously FileSelector and ImageSelector) have been updated to improve symmetry of the two classes.
  6. Content Database

    Two SQL tables - schema in contentlnk.sql* containing an authoritative list of current content . For removable media a temporary (in memory) table is created and is kept up to date with src/server/contentserver.*

        QMenu *menu = new QMenu();
        QSoftMenuBar::addMenuTo(widget, menu)
