Automatic poll from SceneTree is enabled by default.
This allows for polling (and thus RPCs/RSETs) manually in other loops
(e.g. physics, thread, specific step) and for proper mutex protecion
when accessing the multiplayer API from threads (e.g. for sending larger
files in chunks).
Now generating mouse events from touch is optional (on by default) and it's performed by `InputDefault` instead of having each OS abstraction doing it. (*)
The translation algorithm waits for a touch index to be pressed and tracks it translating its events to mouse events until it is raised, while ignoring other pointers.
Furthermore, to avoid an stuck "touch mouse", since not all platforms may report touches raised when the window is unfocused, it checks if touches are still down by the time it's focused again and if so it resets the state of the emulated mouse.
*: In the case of Windows, since it already provides touch-to-mouse translation by itself, "echo" mouse events are filtered out to have it working like the rest.
On X11 a little hack has been needed to avoid a case of a spurious mouse motion event that is generated during touch interaction.
Plus: Improve/fix tracking of current mouse position.
** Summary of changes to settings: **
- `display/window/handheld/emulate_touchscreen` becomes `input/pointing_devices/emulate_touch_from_mouse`
- New setting: `input/pointing_devices/emulate_mouse_from_touch`
Allows shortening the two line method of Timer.set_wait_time
followed by Timer.start set wait_time as a parameter to
Timer.start. Also modifies the class documentation.
Fixes: #18107
It seems that popups were intended to "grab" the mouse click that triggered them, but their intent was being lost. This commit does the necessary changes to let it happen and updates items that were trying to get advantage of it, because the semantics of `Control::grab_click_focus()` have changed a bit. Namely, it must be called **before** showing the modal.
This allows to popup a menu and activate an item in it in a single click-point-release cycle, instead of having to click once to open the menu and once more to pick an item.
This ability is extended even to context menus activated with the RMB (or any other mouse button, for that matter). The editor benefits from this in the context menu of the tree dock, which has been patched to opt-in for this feature.
This improves UX a bit by saving unnecessary clicks.
From now on, `PopupMenu` always grabs the click and also invalidates the first button release unless the mouse has moved (that's what `set_invalidate_click_until_motion()` was doing and now it's removed), so there is no longer the need of doing both things at every point a pop-up menu is shown.
Font update after resize relies on the viewport size which was updated
after the font was already refreshed, which resulted in artifacts when
it was rendered into the actual/new viewport size.
Fixes#15173.
Previously this option seemed to be the sole responsible for enabling
physics processing in Viewport, while several other features like
tooltips and debugging collision hints rely on it.
All this logic is moved to internal processing (it's incorrect to let
it be affected by users disabling physics/idle processing), and disabling
physics object picking no longer affects the internal physics processing.
Fixes#17001.
