This should complete what was started in the HiFi days but didn't quite succeed.
Setting::Manager is now thread safe, and delegates all settings writes to a thread
that nothing waits on, which should ensure that settings don't degrade performance
even on slow storage devices.
Functions that weren't thread safe were removed from Setting::Manager, and it was
reduced to a key/value store.
Functions that modify state like beginGroup were implemented in the Settings class
instead, which should be created only in the context where it's needed. It will
forward all changes to the manager.
A few QSettings functions were left unimplemented because they're not used in
the code. They may be implemented later if there's a need.
Added a gestural way to dismiss the notifications in HMD.
The notifications vanishes after 10 sec.
But if for any reason we want to accelerate the process (mostly because it hide the view or it is going to appears in photo capture)
In Desktop we can simply click on the notification to get rid of them.
But in HMD, clicking was kinda a pain (assuming the if you want to dismiss the notification is often because they are already annoying you)
have to aim and click is like pressing a button using a fishing pole, it's certainly adding more annoyance to this.
To addressed that, I introduced the "Whoosh!": An easy gesture to dismiss any 3d UI, by simply move one of you controller over you eyes height. (a bit like making flee an annoying fly.)
This is a an almost complete re-coding of the notifications script.
The previous version had too useless complexities and was computing each element position independently causing the notifications to be unstably displayed in HMD if the user moved.
There was also too many array used to achieved this. It was a bit painful.
This new version use an invisible entity parented to the avatar as a "container" where the notification elements are parented to it, making the positioning easier and more stable if the avatar moves.
I used only one array of objects to contain the the notification stack.
There is also a better management of some signal to avoid useless computing when it wasn't necessary.
I think the code is also more clear.
I got rid of the little x buttons to close the notification, it was on each element, you had to target a very small square surface with the mouse if you wanted to absolutely close a notification within the 10 second of their existence. Now you can close a notification simply by clicking on it (on all its surface)
But as before, the close function works only on desktop mode. (Apparently it's relatively complex to get the id of the entity that you click on in HMD. Maybe one day.)
It's also easier now to adjust the scale of the notifications in HMD if we want too, (only one value to change in the script)
The parenting using a container entity has also made all the notification UI in HMD scaling correctly according the avatar scale (it was free by parenting all those together).
Upgrade to local Entities and Misc
- All the deprecated use of 3d overly has been changes to Local Entities (Only the addEntity)
- All the preview are now unlit (it was a pain in a dark place)
- The HMD has been repositionned to be visible. (This is a try, I think it is better)
- Many bug fix in HMD
- Added a setting to switch on/off the snapshot related notification (because they are often a nuisance during capture sessions. constantly present and appearing in the capture)
(The setting still need to be plugged in the admin.)
