From 57a5e6be6d581710d7eeaadc91c3b5742fb81b53 Mon Sep 17 00:00:00 2001 From: Christian Kolset Date: Tue, 11 Aug 2026 10:40:12 -0600 Subject: Fix native-style Qt warning; add a few tooltips; trim Namespace hint text MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause of "QFont::setPointSize: Point size <= 0 (-1)" on some dropdowns: the app never sets an explicit widget style, so it defaults to native windowsvista, whose popup code calls setPointSize() on fonts resolved from our QSS's pixel-based font-size (pointSize() is -1 by design for px fonts). Tried app.setStyle("Fusion") first — silences it, but Fusion doesn't render buttons/dropdowns to match the QSS the way the native style does. Kept native style, filtered just that one message via qInstallMessageHandler instead — it's cosmetic Qt console noise (the rejected setPointSize call is a no-op, doesn't affect rendering), not a real bug. Also adds a handful of tooltips (Control Editor's Check Syntax/Cancel/ Create Control, device Configure dialog's Close, main toolbar's View/ Configure/RUN/LOG/Settings, a few Control Panel widgets) from an in-progress app-wide tooltip pass, paused partway through by request — remaining buttons are being done manually.
