| |
|
| |
| ==Key development works and fixes related to the Qt on the <span class="caps">QNX</span> platforms==
| |
|
| |
| ===Tentative plan for Qt 5.4===
| |
|
| |
| * A more broad support of Bluetooth (all platforms)
| |
| * An experimental support for DBus
| |
| * Improvements in QtMultimedia
| |
| * Extensions and integration with new <span class="caps">QNX</span> platform releases
| |
|
| |
| ===In Qt 5.3.0===
| |
|
| |
| ====<span class="caps">QPA</span> for <span class="caps">QNX</span>====
| |
|
| |
| * Improved focus handling
| |
| ** Properly honor “libscreen” keyboard focus
| |
| ** Platform windows can now be activated (receive keyboard focus) by the application
| |
| ** Fixed bugs related to libscreen focus handling
| |
| * Fixed timing issues when creating <span class="caps">EGL</span> surfaces
| |
| * Refactoring (screen error handling, remove dead code, etc.)
| |
| * Populate touch event properties
| |
| * Fixed resizing windows (buffers are destroyed and re-created)
| |
| * Creation of parent-less windows
| |
| * Fixed window re-parenting, positioning and opacity
| |
|
| |
| ====QtBase====
| |
|
| |
| * Added support for the <span class="caps">SPDY</span> protocol (version 3.0) (all platforms)
| |
| * Added support for the Next Protocol Negotiation (<span class="caps">NPN</span>) <span class="caps">TLS</span> extension (all platforms)
| |
| * Fixed ComboBoxes and Popup dialogs (<span class="caps">QNX</span> and BlackBerry 10)
| |
| * Fix application font removal when using Fontconfig (all platforms)
| |
| * Fixed evaluation of font width for selected FreeType fonts (all platforms)
| |
| * Fixed dlclose “Shared objects still referenced” error (<span class="caps">QNX</span> and BlackBerry 10)
| |
|
| |
| ====QtMultimedia====
| |
|
| |
| * Performance improvements for video playback (<span class="caps">QNX</span> and BlackBerry 10)
| |
| * Fix re-play of media. mm-renderer buffer status is now roperly evaluated. (<span class="caps">QNX</span> and BlackBerry 10)
| |
|
| |
| ====QtDeclarative====
| |
|
| |
| * Fix stack order and focus when using <span class="caps">QML</span> Window <span class="caps">API</span> (all platforms)
| |
|
| |
| ====QtLocation====
| |
|
| |
| * Switch tile server for <span class="caps">OSM</span> by MapQuest (all platforms)
| |
| * Prepare the <span class="caps">QML</span> Mapping <span class="caps">API</span> for the <span class="caps">API</span> freeze (all platforms)
| |
|
| |
| ==Known issues==
| |
|
| |
| ===Qt 5.3.0===
| |
|
| |
| ====Fixed in Qt 5.3.1====
| |
|
| |
| * QQuickItem size will not follow window size [https://codereview.qt.io/84008]
| |
| * Qt Quick Controls FileDialog crashes [https://codereview.qt.io/83408] and which perceived by the user as not appearing on the screen.
| |
| * QDir might report directories twice [https://codereview.qt.io/83529] on some folders
| |
| * QFileSystemWatcher::addPath doesn’t handle adding a path more than once correctly [https://codereview.qt.io/83215]
| |
| * Instead of slog2info, Qt debugging and logging output can be forced to go to stderr if the QT_LOGGING_TO_CONSOLE environment variable has been set [https://codereview.qt.io/82914]
| |
|
| |
| ====Other issues and aspects affecting the use of Qt on <span class="caps">QNX</span>====
| |
|
| |
| * Qt Quick animations are running slower than expected if the actual frame rate is less than 60fps on a give target. If an application can not maintain a constant frame rate of 60fps the <span class="caps">QSG</span>_FIXED_ANIMATION_STEP environment variable should be set to “no” to improve the animation speed.
| |
| * Fontconfig is not available in the <span class="caps">QNX</span> <span class="caps">SDP</span> 6.6 release. Qt compiled for <span class="caps">QNX</span> <span class="caps">SDP</span> 6.6 falls back to the internal font database. You need to set QT_QPA_FONTDIR pointing to the location of Qt fonts on target (typically in the ./lib/fonts)
| |
| * <span class="caps">QNX</span> <span class="caps">SDK</span> for Apps and Media 1.0 does not provide Fontconfig for the x86 target. Qt compiled for this target falls back to the internal font database. See the previous point for a workaround. A patch from <span class="caps">QNX</span> is in the work to resolve this issue and will be published on http://qnx.com
| |
| * Even though cmake files for Qt are provided in a Qt build for <span class="caps">QNX</span> Neutrino OS by default, their use is not supported, since <span class="caps">QNX</span> <span class="caps">SDP</span> 6.6 does not supply a toolchain file for cmake. It is still possible to provide a custom toolchain file and use cmake with Qt on <span class="caps">QNX</span>. * On-screen virtual keyboard is not provided by <span class="caps">QNX</span> <span class="caps">SDP</span> 6.6, nor by the <span class="caps">QNX</span> <span class="caps">SDK</span> for Apps and Media 1.0. An external hardware keyboard should be used or an own virtual keyboard implementation has to be configured.
| |
| * Qt widgets and Qt Quick controls use the default style when started on a <span class="caps">QNX</span> target. This style is a very basic implementation with a very limited visual appearance. A complete style should be implemented to follow all look-n-feel requirements of a specific project.
| |
| * QClipboard is currently not supported
| |
| * QCursor is currently not not fully supported due to limitations in the <span class="caps">QNX</span> Screen Graphics Subsystem
| |
|
| |
| ===Qt 5.2.x and earlier===
| |
|
| |
| See the [[Qt5 Status on BlackBerry10|list of know issues for BlackBerry 10]] for now. Most of them are applicable. More details will be provided by time of the Qt 5.3.0 final release.

|
| |
| ==Where and how report issues==
| |
|
| |
| Please use the the [https://bugreports.qt.io/browse/QTBUG/component/20920 QtPorts: <span class="caps">QNX</span>] ''[bugreports.qt.io]'' component for <span class="caps">QNX</span> specific issues and other components for Qt generic issues even if you found them on <span class="caps">QNX</span> Neutrino OS.
| |
|
| |
| ==Access the status of the Qt CI system for <span class="caps">QNX</span> Neutrino OS==
| |
|
| |
| BlackBerry and <span class="caps">QNX</span> run a Jenkins based CI system which conducts build and on-device unit tests: http://qtlab.blackberry.com/
