Python for S60 2.0.0 released.

Changes 2.0.0 from 1.9.7:

• Repeat support in 4-way directional pad
• Lot of memory leaks in the interpreter code is fixed.
• appuifw.app.track_allocations can be set if the interpreter should track all memory allocations and then free the memory which was not explicitly released before application exit. To debug memory leaks in 3rd party extension modules set the value to false.
• All the Pyds that have zero UID will be assigned with the applications UID at the time of packaging.
  As a result, Python applications can now be symbian signed. This opens the door for submitting Python applications to OVI Store.
• Pdf documentation is available in the installer/archive.
• API cleanup in the SensorFW module.
• On the below mentioned devices Python runtime and its dependencies will be installed automatically when the Python applications is started. 6220 classic, N86 8 MP, N85, 6720 classic, 6730 classic, N96, 5730 XpressMusic, N78, 5630 XpressMusic, E52, E55, 6710 Navigator, E75, N79, 5800 XpressMusic, 5530 XpressMusic, 5230, X6 and N97 mini

Feature requests:

• 3792 – Python Runtime and application sis can be on different drives. The limitation of both should be installed on the same drive is eliminated.

Corrected defects:

• 4345 – Missing (platform) functionality on ensymble/Application packager: The 2nd point in the bug description is fixed
• 3935 – appuifw.Icon sample code refers to non-existing file [doc error]

The Symbian platform is a free open-source software platform for mobile devices. From Symbian^3 onwards you can get any of the source, modify it, and contribute back the changes.

The source code is organised into a number of discrete packages, as described in the Symbian System Model. It comprises about 25 million lines of code (around 40 million if you include the test and tools code) in 200,000+ source files.

ApiBridge enables developers to extend the features of Web Runtime widgets by using various capabilities of Symbian OS. The capabilities available include:

• Uploading files.
• Capturing video, image, and audio.
• Reading files.
• Resizing images.
• Creating image thumbnail.
• Using the logging service.
• Using the location service.
• Using the media management Service

Supported platforms
ApiBridge can be used to access Symbian OS capabilities from WRT widgets on the following platforms:

• S60 5th Edition.
• S60 3rd Edition, Feature Pack 2.
• S60 3rd Edition, Feature Pack 1.

Python for S60 1.9.7 released.

Changes 1.9.7 from 1.9.6:

• Touch support added for GLCanvas UI Control. Directional pad is displayed by default on touch enabled devices. A sample application – gles_touch_demo.py is added to ScriptShell which demonstrates the functionality.
• Two new APIs are added to canvas – begin_redraw and end_redraw. These can be used to instruct the window server to enable redraw drawing on the canvas UI control. Please refer the documentation (Section 3.1.10) for more details.
• The multi-selection listbox has been modified such that the dialog for the option ‘checkmark’ now has ‘Options’ and ‘Back’ as its left and right softkeys respectively. The ‘Options’ has Mark/Unmark entry that can be used to select and de-select respectively. The ‘Back’ softkey returns the current state of the listbox based on the selected items.
• 4-way directional pad support in landscape mode
• Different flavors of Scriptshell application can coexist on the device.
• Scribble application improvements:
  - Performance improvement by using API’s begin_redraw and end_redraw.
  - The drawing area is retained between landscape and portrait modes as the toolbar shifts to accommodate for this change.
  - Pen width can be selected from a list of predefined values.
• PyS60 document is available online on maemo.garage http://pys60.garage.maemo.org/doc/

Corrected defects:

• 4251 – The compression type for the dll and exe files for Python is shown as Deflate instead of Byte-pair.
• 4313 – Scrollbar visible afterwards, should not be there
• 4338 – Multiple lisbox objects decrease scroll performance
• 4349 – time.mktime() taking too much time to execute

Python for S60 1.9.6 released.

Changes 1.9.6 from 1.9.5:

• Support for a virtual 4-way directional pad is added for Canvas and text widgets. This D-Pad is displayed at the bottom of the screen and this eauture is enabled by default on touch enabled devices. Currently, this is supported only in the portrait mode and landscape support will be available in a future release.
  The ‘full_max’ mode is invalidated by this change and is removed in this release.
• The modules in the base runtime is more refined and hence the size of application SIS, created using PyS60 Application Packager is reduced.
• A new chapter is added in the PyS60 documentation (Extending and Embedding PyS60), that is an end-to-end tutorial for creating 3rd party extention modules and distributing them.

Corrected defects:

• 3223 – Floating point formatting/parsing routines on this platform are imprecise
• 4078 – socket.access_points() returns iapid 0 for lots of entries
• 4106 – Problems exiting standalone apps
• 4185 – Calendar module returns end time with time zone offset added to Unix time
• 4186 – Using rollback in calendar module returns error
• 4198 – Screen orientation remains landscape after exit, while device was portrait all the time
• 4215 – default.py cannot load .pyc files
• 4216 – sys.exit() doesn’t exit Python3228 – time.clock() does not work as expected.
