Override the LETTERBOX logical presentation while the scroller is
active so it renders into the full physical window. On a 1920x6480
rotated display the scroller now scrolls through all 6480 pixels of
vertical space instead of being confined to the 1920x1080 letterbox
region. Text scale is unchanged (same font size, same pixel
rasterization); more lines are simply visible at once.
- onPush: save current logical presentation, switch to DISABLED with
real window dimensions
- onPop: restore the saved LETTERBOX presentation
- resize handler in main.cpp: skip re-apply while scroller is active
(it owns its own presentation and restores on pop)
- Sub-categories start expanded and cannot be collapsed
- Only root categories toggle open/closed
- LEFT on a sub-category is ignored (navigates to parent for depth-2)
- [+]/[-] indicators only shown on root categories
- Bounding box width computed over all items to prevent
horizontal shifting when groups expand or collapse
SDL_CreateWindow hardcoded a 1920x1080 backbuffer while SDL_WINDOW_FULLSCREEN
let compositors run a different output mode; the mismatched buffer reached
the panel unscaled — quarter-size in the top-left on 4K sets, cropped ("4x
too large") on smaller non-1080p panels under cage/Wayland. Logical
presentation never got to map the fixed design space because its target
(the backbuffer) was pinned to stale dimensions.
Size the fullscreen window from SDL_GetCurrentDisplayMode so the first
commit already matches scanout 1:1, switch logical presentation to LETTERBOX
(aspect-safe bars on non-16:9 panels), and route both through new
kDesignWidth/kDesignHeight constants. Harden getLayoutSize() to always write
its out params and null-check the renderer/render-window before use.
Log requested/window/pixel-buffer/render-output sizes at startup and on
every resize event so field units self-diagnose this bug class into
~/.local/radiantwave/log.txt. SDL_WINDOW_HIGH_PIXEL_DENSITY stays off on
purpose: kiosk panels are not HiDPI, and keeping the pixel buffer equal to
the display mode keeps compositor scanout unscaled.
Pages computed layout from SDL_GetWindowSize() (real window
coordinates) while SDL_SetRenderLogicalPresentation() independently
remapped every draw call into a 1920x1080 space. The two coordinate
systems only agreed when the window happened to be exactly 1920x1080;
at any other size, layout coordinates were transformed a second time,
so content shrank/grew quadratically toward the top-left on resize or
on non-1080p monitors. Commenting the call out masked the bug by
making rendering 1:1 with the window, but then nothing scaled: fonts
and margins stayed fixed-pixel while backgrounds cover-fit, and HiDPI
displays drew at point resolution and relied on blurry compositor
upsampling.
Restore SDL_SetRenderLogicalPresentation(1920x1080, LETTERBOX) as the
single source of scaling, and route all twelve layout sites through a
new radiantwave::getLayoutSize() helper (src/logical_size.h) that
returns the renderer's logical size, so pages always lay out against
the design resolution regardless of window or monitor geometry. Add
SDL_WINDOW_HIGH_PIXEL_DENSITY so HiDPI displays render at native pixel
density instead of being upscaled by the OS. Cached per-page textures
become resolution-independent since layout no longer depends on window
size.
The scroller recycled at most one line per frame while movement was
continuous (velocity * dt), so whenever a frame's displacement exceeded
one line height the text block drifted toward the boundary and the
screen drained with nothing replacing it. This surfaced on slower
hardware / 60Hz panels (|move| > lineHeight) but not on fast machines.
Recycle in a loop until every line that scrolled fully off-screen has a
replacement, for both scroll directions. addLineAt() now returns whether
a line was produced so the loop stops cleanly instead of losing lines.
AllAccessPoints is not exposed by this NetworkManager ('No such property'),
so getAccessPoints() hit the error path and returned an empty scan list
with no log output. AccessPoints is the current scan results and is
universally supported. Also log the property-read failure instead of
failing silently.
parseAccessPoint() is extracted from an anonymous namespace so the pure
property->AccessPointInfo mapping is testable. getAccessPoints() now reads
the Flags/WpaFlags/RsnFlags properties (they were never read, so every
network was reported Open and connections lacked a security section) and
fixes the double container-enter on the SSID 'ay' read that silently
emptied the scan list.
The WiFi page only re-read the access-point list every 3s, so a scan
that was slow, denied, or interrupted left the network list permanently
empty until a manual F5. Re-request the scan on each timer tick (skipped
while a connection attempt is in flight) so results appear automatically
once NetworkManager completes a scan.
The RequestScan result and the underlying sd_bus error were silently
dropped, so a denied or failed scan looked identical to an empty scan
list on the WiFi setup page. Surface both so the deployed-machine
diagnosis (e.g. user not in the networkmanager group) is visible in
~/.local/radiantwave/log.txt.
