From d724ec6dd459d0ce563bb50a5a5d2229347dc2ee Mon Sep 17 00:00:00 2001 From: Breadway Date: Wed, 26 Aug 2026 09:43:50 +0800 Subject: [PATCH] capsule: open only on real user input, never on focus or programmatic text Three prior fixes failed because each neutered one path that called open_fn while others remained. This inverts the approach: opening is now gated on the input actually coming from a person. - connect_enter no longer opens. Focus alone is not intent, and GTK grants focus during window construction, which is what put the capsule in its open state at startup. - connect_changed skips when a programmatic_text_change flag is set, so close_fn's set_text("") and initial buffer setup cannot reopen it. - A click gesture and the OpenLauncher hotkey are the only paths that open. - BREADBAR_CAPSULE_DEBUG=1 traces every open/close and why, so a future accidental open is diagnosable instead of mysterious. Compiles and tests pass, but NOT yet verified against a live compositor: the agent that wrote this was interrupted before running it. The startup-collapsed check still needs a real session. --- src/main.rs | 109 +++++++++++++++++++++++++++++++++++++++++++++++++--- 1 file changed, 104 insertions(+), 5 deletions(-) diff --git a/src/main.rs b/src/main.rs index 23ae426..e78ff10 100644 --- a/src/main.rs +++ b/src/main.rs @@ -38,6 +38,26 @@ use std::rc::Rc; const LAUNCHER_APP_ID: &str = "box"; const LAUNCHER_LAUNCHED_EVENT: &str = "bread.box.launched"; +/// Diagnostic trace for the capsule's open/close/focus wiring, gated +/// behind an env var so it costs nothing by default.
