The '''CSSU Features Configuration Editor''' is a user interface to the configuration of several parameters enabled by the [[Community SSU]] updates.

It has been built using the PyQt libraries and the Python language.

It provides the ability to change a number of parameters in the transitions.ini configuration file as well as the relevant GConf entries' values. The options are described in the [[Community SSU/Features]] wiki page.
Additional information on the usage, settings and implications could be found below.

==Installation==

The application is hosted in the [[Extras]] repositories. Its status can be seen at the [http://maemo.org/packages/view/cssufeatures/ packages page]

The latest stable version can be found also in the [http://maemo.org/downloads/product/Maemo5/cssufeatures/ Downloads page]

The project is also hosted in [https://garage.maemo.org/projects/cssufeatures/ Maemo Garage]

===Dependencies===

The application depends to the following packages:
 * python2.5
 * python2.5-qt4-gui
 * python2.5-qt4-core 
 * python2.5-qt4-maemo5

==Usage info==

===Start-Up===

On the application start-up the <code>transition.ini</code> file and the relevant GConf key entries are read.

Their values are shown in the corresponding UI elements.

Depending on the orientation of the device one gets a different view.

The application uses the accelerometer to provide landscape or portrait modes.

Both modes are fully usable without the need of a keyboard.

===Errors===

When the application starts it checks first if the [[Community SSU]] is installed.
In the case it does not finds it an error message is displayed.

'''Note''': In the latest versions the application does not exit but continues allowing custom/partial installations of the CSSU to have the ability to edit their options using this application.

[[Image:CSSUfeaturesConfiguration_error1.png|350px]]

Subsequently, a check is made if the options in the <code>transition.ini</code> file are available for editing.

In the case of their unavailability, a new window opens which provides information and two ways to resolve this.

The options are to either try to fix by adding the missing variables in the configuration file or restore the complete file by replacing it with a default.

The messages given in either case are similar to those:

[[Image:CSSUfeaturesConfiguration_fixWindow_optionFix.png|350px]]
[[Image:CSSUfeaturesConfiguration_fixWindow_optionDefault.png|350px]]

''NOTE:'' After the completion of either operation the application exits.
 
In the case the file is corrupted and cannot still be read an error banner is displayed for user information. In this case, the application exits.

===Changing Options===

The operation of the application is simple: 
* Choose the options you would like to have (for info on the options look in the [[Community SSU/Features]] page).
* Press the "Update" button to register in the system your choice.

[[Image:CSSUfeaturesConfiguration_edit2.jpg|250px]]

'''''Note''''': Options like the "tactile feedback" will be '''disabled''' if the relevant package is not installed.

===Button functions===

* The "Current" button sets the current options the system is using in the options (which are shown also in the startup of the application)
* The "Default" button sets the values in UI equal to those shipped with the Community SSU.
* The "Update" button registers the choices seen in the UI to the system.

[[Image:CSSUfeaturesConfiguration_current.png|350px]]
[[Image:CSSUfeaturesConfiguration_default.png|350px]]

'''''Note''''': Neither of those buttons propagate any changes to the system. They will only set the UI elements. The options visible in the UI will be applied only after pressing the "Update" button.

===Restoring to Default Options===

'''''Note''''': This will restore to the shipped version of the transitions.ini and will not have any effect on the similar file in <code>/etc/hildon/theme/</code> that might be used by theming.

If for some reason the transitions.ini file becomes messed up it is possible to restore the default:

* Open the application menu. 
 * Choose the "Restore Defaults" option.

[[Image:CSSUfeaturesConfiguration_restore.png|350px]]

If the application exits immediately when started the same operation can be done from the command line:

* Open the xterm (shortcut: shift [arrow up] + ctrl + x)
 * type the following:

<code>sudo /opt/CSSUfeatures/updateTransitions copyDefault</code>

===Applying changes to the system===

* Some of the options get immediately active as soon as you press the "Update" button. 
 * Others need the hildon-desktop to be restarted. For those a menu option is available "Restart hildon-destop".

[[Image:CSSUfeaturesConfiguration_update.png|350px]]

===Power Key Menu entry===

By default an entry is added in the Power Key Menu.

[[Image:CSSUfeaturesConfiguration_powerkeyentry.png|350px]]

This entry can be removed or added any time from the application's menu.
 * Open the application menu. 
 * Choose the "Remove PowerKey Entry" option.
 '''''Note''''': If the entry has already been removed the option will be "Add PowerKey Entry"

===About window===

In the About window, apart from the application version and description, one can find a button pointing to this page.

==Issues & ToDo==

'''Feel free to add requests below''' (optionally adding also your username for reference):

* <strike>It only edits transitions.ini located under /usr/share/hildon-desktop/. Thus, will fail if you have more transitions.ini files (e.g. using the theme-customizer).</strike> fixed in version [[#0.3-1]]
* <strike>Current button is not yet implemented.</strike> fixed in version [[#1.0-1]]
* <strike>The application when it opens shows the default options - in a future update will show the system's current options.</strike> fixed in version [[#1.0-1]]
* <strike>'''BLOCKER''': In the "parallax" field the values need to be float, i.e. "2.0" and not "2", otherwise the GUI fails to open.</strike> fixed in version [[#1.1-1]]
* <strike>MINOR: if "tactile" package is installed and disable option if it's not.</strike> fixed in version [[#1.2-1]]
* <strike>MINOR: Add rotation support.</strike> fixed in version [[#2.1-1]]
* Enhancement: The application should reside in the Settings under Personalisation. At the moment it is in the applications.
