|
Class to wrap QSettings.
|
||||||
|
|
||||||
|
* Exposes all the methods of QSettings.
|
||||||
|
* Adds functionality for OpenLP Portable. If the ``defaultFormat`` is set to
|
||||||
|
``IniFormat``, and the path to the Ini file is set using ``set_filename``,
|
||||||
|
then the Settings constructor (without any arguments) will create a Settings
|
||||||
|
object for accessing settings stored in that Ini file.
|
||||||
|
|
||||||
|
``__default_settings__``
|
||||||
|
This dict contains all core settings with their default values.
|
||||||
|
|
||||||
|
``__obsolete_settings__``
|
||||||
|
Each entry is structured in the following way::
|
||||||
|
|
||||||
|
(u'general/enable slide loop', u'advanced/slide limits',
|
||||||
|
[(SlideLimits.Wrap, True), (SlideLimits.End, False)])
|
||||||
|
|
||||||
|
The first entry is the *old key*; it will be removed.
|
||||||
|
|
||||||
|
The second entry is the *new key*; we will add it to the config. If this is just an empty string, we just remove
|
||||||
|
the old key.
|
||||||
|
|
||||||
|
The last entry is a list containing two-pair tuples. If the list is empty, no conversion is made. Otherwise each
|
||||||
|
pair describes how to convert the old setting's value::
|
||||||
|
|
||||||
|
(SlideLimits.Wrap, True)
|
||||||
|
|
||||||
|
This means, that if the value of ``general/enable slide loop`` is equal (``==``) ``True`` then we set
|
||||||
|
``advanced/slide limits`` to ``SlideLimits.Wrap``. **NOTE**, this means that the rules have to cover all cases!
|
||||||
|
So, if the type of the old value is bool, then there must be two rules.
