* Special thanks to @HexF and @smlu for their contributions towards this feature.
* Add MVP support for Windows Hello as a Quick Unlock solution using the WinRT API. This works by signing a random challenge vector with the Windows Hello protected key store (typically from TPM). The signed challenge is hashed using SHA-256 and then used as the encryption key to encrypt the database credentials. Credentials are encrypted using AES-256/GCM. This ensures the database password can only be decrypted following a successful authentication with Windows Hello in the future.
* Unify Touch ID and Windows Hello behavior under the Quick Unlock branding. Remove all timeout features of Touch ID as they are unnecessary and complicate the feature for no security gain.
* Quick Unlock is automatically reset only when the database key is changed vice whenever database settings are modified.
* Don't set database unlock dialog as always on top. This allows Touch ID and Windows Hello prompts to appear above the dialog properly.
* Prevent quick unlock when using AutoOpen or opening from the command line.
Some widgets such as QTableView do not call QIconEngine::pixmap(), but do
the drawing immediately through QIconEngine::paint(). This breaks alpha
blending for recolouring, since the underlying image canvas is not
necessarily transparent and also not anchored at (0, 0). This results in
a black box of the size of the icon bounding box.
Icon recolouring is now always done on a temporary QImage with
transparent background and only the finished end result is composed onto
the original canvas.
Fixes#6006
- 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.
