* Play whole file in spectrum analyzer demoGareth Stockwell2010-10-2911-467/+369
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change required a significant refactoring of the application, including: * Re-write WavFile class so that it inherits from QFile rather than taking a QIODevice as an argument to its method calls. * Modified Engine class so that its internal QByteArray buffer (m_buffer) need not correspond to the entire clip. This was done by introducing the m_bufferPosition variable, which indicates the offset from the start of the clip to the start of the region of the clip which is currently held in memory. For tone generation and record/playback modes, the buffer does still map directly to the whole clip, so m_bufferPosition is always zero. For file playback, the WavFile instance is the QIODevice which is passed to QAudioOutput; m_buffer is just the part of the file which is currently in memory for spectrum analysis, level calculation and waveform rendering. * For file playback, introduced a second WavFile instance as a member of the Engine class. This is because QFile::seek() is called in order to read the part of the file currently required for analysis. If the QAudioOutput implementation passes its QIODevice across a thread boundary, this seeking causes playback to jump around within the file rather than progressing smoothly forward. * Modified the audioLength utility function so that its return value is always a multiple of the sample size. In the process of making the above changes, a few other minor modifications were made: * Modify all internal APIs concerned with buffer offsets and lengths to deal in bytes. Previously, some calls passed values in microseconds and others in bytes, which was confusing. * Remove write functionality from WavFile class, since it is not used in this application. Task-number: QTBUG-12936
* Do not unnecessarily reset state of spectrum demoGareth Stockwell2010-10-293-45/+61
| | | | | | | | | | | | | | | | | | | This patch ensures that the state of the application is not reset when: - Any of the 'Play generated tone', 'Play file' or settings dialogs are opened - Any of the 'Play generated tone', 'Play file' or settings dialogs are dismissed by pressing the Cancel button - A new input or output device is selected via the settings dialog, and that new device supports the data format which is currently being used within the application - The window function is changed via the settings dialog Note that the application is still reset if a new input or output device is selected via the settings dialog, and this device does not support the current data format.

* Avoid being killed by graphics out-of-memory monitor.Jason Barron2010-10-291-0/+11
| | | | | | | | | | | | | | | | | When an application requests more graphics memory, the GOOM monitor will start looking for other applications to kill in order to recover the requested graphics memory. The first step in this process is to send a custom event to the application indicating that it is a candidate for termination. If the application does not acknowledge this event, it will be killed immediately. However, since Qt releases its graphics memory when the app is obscured, we should indicate that we handle this event such that Qt has a chance to finish freeing resources. If after a certain time, the app has not freed its resources it will be killed anyway. This essentially buys Qt some time to avoid the case where Qt apps are killed while they are cleaning up.

* Support tactile feeedback from QS60Style for QWidgetsSami Merila2010-10-2910-2/+249
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently tactile feedback is not given for QWidgets running on Symbian even if the native side supports this (Sym^3 and 5th Edition devices). This task adds support for QWidgets having QS60Style. The tactile feedback has been implemented as a plugin that the style loads when instantiating itself for touch devices. NOTE that the feedback is NOT supported by the emulated style, nor is the plugin interface public, so it cannot be used outside of style. The implementation is simplistic, since we only want to provide stop-gap solution until 4.8 when real Qt feedback implementation is ready. The implementation will only give feedback for touch-down events for visible, interactive and enabled widgets. Sliders and scrollbars will use sensitive feedback (slightly less aggressive) and all others will use basic feedback. Note that Sym^3 adds tens of different feedback categories, which this plugin ignores as we want to share the same implementation for Sym^3 and 5th ed. In distributed Qt package there is no tactile feedback for 5th edition, due to package creation limitations. Support can be added manually by re-compiling Qt on top of 5th Edition SDK.
