Kept out of app_runtime on purpose: that module imports PySide6 at the
|
|
top, and the test suite runs without Qt installed (CI installs only
|
|
httpx, Pillow, pytest). Anything a test needs to read lives here.

# Base popout overlay style — always loaded *before* the user QSS so the

|
# floating top toolbar (`#_slideshow_toolbar`) and bottom video controls
|
|
# (`#_slideshow_controls`) get a sane translucent-black-with-white-text
|
|
# look on themes that don't define their own overlay rules. Bundled themes
|
|
# in `themes/` redefine the same selectors with their @palette colors and
|
|
# win on tie (last rule of equal specificity wins in QSS), so anyone using
|
|
# a packaged theme keeps the themed overlay; anyone with a stripped-down
|
|
# custom.qss still gets a usable overlay instead of bare letterbox.

/* 24x24 glyph buttons (preview + popout toolbars) opt in via the
|
|
iconBtn dynamic property. Theme QPushButton padding (2px 6px + 1px
|
|
border) would leave a 10px content box and clip the glyph. An
|
|
attribute selector outranks a bare type selector on QSS specificity,
|
|
so this holds no matter what a custom.qss sets on QPushButton. The
|
|
overlay containers get their own variant because themes style
|
|
`QWidget#_slideshow_toolbar QPushButton` (ID + type, 1-0-1), which
|
|
would beat the bare attribute rule (0-1-1); ID + attribute + type
|
|
(1-1-1) wins. One font size for both toolbars so the glyphs match.
|
|
Geometry is pinned here rather than left to setFixedSize: QSS
|
|
min-width, min-height, max-width and max-height are written straight
|
|
onto the widget's own minimum and maximum size (content-box relative),
|
|
so a theme's `min-height: 17px` on QPushButton, or a `min-width: 0`
|
|
here, silently replaces the 24px minimum and the layout shrinks each
|
|
button to its glyph width.
|
|
Never write the sequence star-slash inside this comment: it closes the
|
|
CSS comment early, Qt then rejects the whole application stylesheet,
|
|
and every custom.qss user silently loses their theme (2026_08_28). */
