App is responsive to the OS theme change event.
Now we're following system set theme when the app is started.
Corresponding part on the side on nimqml is added.
Corresponding part on the side on dotherside is added.
On the side of dother side we had kind of a memory leak, cause objects added to
the filter were not deleted ever. When the app is closing, it just removes
filters, but doesn't delete them.
I faced a logical issue, that we were sending qmlengine pointer to the
installEventFilter method, instead object which may or may not rely on the
qqmlengine instance, that is fixed also.
Fixes: #1725
As discussed in https://github.com/status-im/status-desktop/issues/2144#issuecomment-817791172 and https://github.com/status-im/status-desktop/discussions/2145, it's no longer desired
to have different appearance settings across multiple accounts.
Instead, the appearance setting should apply globally to all accounts,
essentially bypassing the individual setting stored in status-go.
This commit introduces a new global setting called `theme` which,
at the time of introducing this commit, can be either:
0 => Light
1 => Dark
2 => System
Because those enum values matches the `AppearanceContainer.Theme` enum,
this commit removes it completely and simply relies on QML's built-in
`Universal.[Light|Dark|System] variants respectively.
Closes#2144
Supports system dark mode. Changes the user appearance setting to a 3-way setting of System, Light, Dark.
New accounts will have their appearance setting set to "System", which uses the system setting to determine if dark mode should be applied.
Breaking change: Users who had their settings on Light Theme, will now get the system theme (light or dark). Users who had their theme set to Dark, will now get the Light theme.
At startup, the onboarding screens will have the system-level setting of dark mode applied or not. Once, logged in, the user settings will be applied.
## Note
An appearance setting of "System" is not dynamic to the system-level setting. This means that if a user has "System" set for their appearance (and ie, the user has light mode set), and then user then changes their system setting from light to dark, the app will not respond until it is restarted. This is due to a limitation of Qt not having a reliable way to propagate these changes to QML.
