From a1d8ce6165e33927fb3cc9f0e69e5d8c320cbadf Mon Sep 17 00:00:00 2001 From: BruebachL <44814898+BruebachL@users.noreply.github.com> Date: Wed, 23 Sep 2026 21:03:34 +0200 Subject: [PATCH] [Accessibility] Bind card size sliders to Ctrl + Scroll (#7338) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Ctrl+scroll over a card display now resizes the cards everywhere a card size slider is shown, matching the standard way of resizing content. CardSizeWidget learns to forward Ctrl+wheel events onto its slider via an event filter that is installed on the display container and, when present, on the scroll area's content widget so the resize intercepts the wheel event before the view scrolls. The existing slider valueChanged wiring then rescales the displayed cards. Applied to the visual deck editor (per card group, covering flat and overlapped layouts), visual database display, printing selector, sample hand, visual and public deck storage, Archidekt previews and EDHRec card displays.
