The visibility of the `ScrollBar` was used as a condition for judging whether it should scroll.
**Visible** and **scrollable** are currently not the same in some cases (`SCROLL_MODE_SHOW_NEVER`).
This makes `SCROLL_MODE_SHOW_NEVER` not working properly.
This patch will make `SCROLL_MODE_SHOW_NEVER` available, so that the external `SrollBar` can
share the internal `ScrollBar`'s data, we can achieve the purpose of replacing the internal
`ScrollBar` with a custom external one.
Camera2D has follow smoothing to interpolate towards a target position, but no rotation smoothing to align with the target rotation.
This adds rotation smoothing directly into the Camera2D API by having two new properties:
- `rotation_smoothing_enabled`
- `rotation_smoothing_speed`
Connects AtlasTexture to its `atlas`'s "changed" signal, allowing it to detect property changes to `atlas` and update accordingly, when the project is running and in the editor, as well.
Instead of exporting the "create_debug_tangents" function via
METHOD_FLAG_EDITOR it gets executed by an editor plugin.
This moves it from the "Manage object properties" menu into a mesh menu. It also adds undo/redo functionality to the create debug tangents option.
- `LIBC_FILEIO_ENABLED` wasn't defined anywhere, even in _other platforms_.
- `NO_NETWORK` is also never defined. It probably isn't enough anyway to
disable network APIs in the current codebase.
- `UNIX_SOCKET_UNAVAILABLE` is never defined in this code but used by some
other platforms, clarify that.
- `NO_STATVFS` can be removed as Android supports it since API level 19,
which is our current min SDK level. It's also only used for
`DirAccessUnix::get_space_left()` which is anyway overridden by
`DirAccessJAndroid::get_space_left()` so it shouldn't make a difference.
* Fixed documentation for `DirAccess.get_space_left()`.
- `NO_FCNTL` is likely also a remnant of early Android days, in current NDK
r23 it seems to be available. Also cleaned up unused `fcntl.h` includes.
- `NO_ALLOCA` is never defined, and we use alloca in many places now.
* MenuButton + OptionButton: Add method `show_popup()` which performs required popup setup before showing (prefer use of this over `get_popup()->popup()`, otherwise GH #66308 occurs)
* MenuButton: Ensure that the menu can be opened with a shortcut, if one is set for the button. (GH #66403). Ensure that popupmenu item shortcuts are checked first before the MenuButton shortcut.
* Focus into the LineEdit, then perform input to search the list of events by the events assigned.
* New specialised editor-only control for this: EventListenerLineEdit. Line edit is a good candidate for such a control because you can focus it, override it's input handling, and show the event all in one control.
Update InputEventConfigurationDialog to use event listener line edit rather than the separate tabs.
* Cleaner look - no need for tabs.
* Simpler code.
