- Allow switching between themes without restart (except classic)
- Rework icon loading and recolouring logic to react to theme changes
- Automatically react to light/dark theme change
- Remove explicit selection of monochrome tray icon variant (selected
automatically now)
- Update theme background colours for Big Sur
- Update application icon to match Big Sur HIG
The tray icon doesn't respond perfectly to theme changes yet on Big Sur,
since we need different icons for dark and light theme and cannot simply
let the OS recolour the icon for us (we do that, too, but only as an
additional fallback). At the moment, there is no signal to listen to
that would allow this.
This patch adds a few generic methods to OSUtils for detecting and
communicating theme changes, which are only stubs for Windows and Linux at
the moment and need to be implemented in future commits.
Fixes#4933Fixes#5349
The classes used for screen lock detection use QWidget and are only ever used by the GUI,
so moving them there so we can eventually build core/ without Qt5::Widgets.
The light and dark theme don't respond to Windows's high contrast
accessibility mode, so when the theme is set to "auto", we
default to "classic" instead of "light".
Fixes#5044
Transforms application into a UIElement agent app when
minimize to tray is enabled and the window is hidden.
This hides the dock icon and removes the application
from the Cmd+Tab listing. The changes work well together
with macOS's inbuilt hide feature.
Also fixes the buggy tray icon context menu trigger behaviour.
macOS triggers the tray context menu also on normal left
click, which causes the window to toggle at the same time
as the menu. To fix this, window toggling has been disabled
altogether on macOS and users will be shown only the context
menu from now on.
Fixes#1334
Moves MacUtils into a separate sub folder and adds
WinUtils, NixUtils, and OSUtils for platform-native
code on Windows, Unix-like, and generic/all systems.
