The previous implementation for signals mouse_entered and mouse_exited
had shortcomings that relate to focused windows and pressed mouse buttons.
For example a Control can be hovered by mouse, even if it is occluded by
an embedded window.
This patch changes the behavior, so that Control and Viewport send
their mouse-enter/exit-notifications based solely on mouse position,
visible area, and input restrictions and not on which window has
focus or which mouse buttons are pressed. This implicitly also
changes when the mouse_entered and mouse_exited signals are sent.
This functionality can not be implemented as a part of
Viewport::_gui_input_event, because of its interplay with Windows and
because Viewport::_gui_input_event is based on input and not on
visibility.
At the moment it is impossible to distinguish between focused and
unfocused embedded Windows.
Add a new `theme_item` that is used for coloring the border of
unfocused Windows.
We don't use that info for anything, and it generates unnecessary diffs
every time we bump the minor version (and CI failures if we forget to
sync some files from opt-in modules (mono, text_server_fb).
Adds a check to make_rst to look for matches
between the text inside of the [code][/code] tag
and known param identifiers.
Fixes most of what was revealed.
This makes it easier to spot syntax errors when editing the
class reference. The schema is referenced locally so validation
can still work offline.
Each class XML's schema conformance is also checked on GitHub Actions.
The new default project theme uses StyleBoxFlat extensively for
a more modern design and better scalability to multiple resolutions.
SVG icons are now used in place of PNG icons. While this does not
allow for true vector-based icon drawing (icons are still rasterized
at load-time), this makes the design work easier for contributors
and opens the door to vector drawing in the future (e.g. with polygons
or SDFs).
Like for editor icons, the SVG header file is now built automatically
when a SVG file is changed. This removing the need for running
`make_header.py` manually (TODO).
The "Use Hidpi" project setting has been removed in favor of a
"Default Theme Scale" project setting, which allows creating the
default theme at a higher/lower scale than the default.
This can be used when designing GUIs with a high base resolution
to ensure crisp visuals.
