Removed GTK2 compatibility shims from headers (fe-gtk.h, gtkutil.h), leaving direct GTK3-facing declarations/includes only (and platform-specific guards unrelated to GTK2 kept as-is).
Cleaned GTK2-specific comments/wording now that behavior is GTK3-native (menu accelerator note and emoji/userlist comment blocks).
Updated multiple GTK UI layout paths (setup, server list, notify, ban list, join dialog, and menu) to use the new helpers for GTK3-safe box/grid creation and attachment behavior.
Added GTK3-safe attach option definitions and updated helper signatures to avoid GTK2-only types/macros in public headers.
Updated gtkutil grid-attachment helpers to use the new attach option type in alignment/expansion logic.
Switched banlist grid attachments to the new helper option flags for GTK3 builds.
Added a GTK3-only helper to translate Pango font fields into font-family, font-size, font-style, font-weight, font-variant, and font-stretch CSS declarations while preserving GTK2 behavior under #if !HAVE_GTK3.
Reused the GTK3 font CSS helper in the main UI font styling path to eliminate remaining Pango font: shorthand usage that triggers GTK3 theme parsing warnings.
Exposed the GTK3 font CSS helper in gtkutil so callers can emit CSS-compliant font properties consistently.
Exposed the new gtkutil stock helper APIs in the header for reuse.
Swapped setup dialog stock button creation to the new gtkutil_button_new_from_stock helper (including the sound play button fallback).
Switched channel tree and theme application logic to use the new palette helper.
Updated entry and user list styling to route palette/font application through the helper.
Updated gtkutil_button() to use icon-name images on GTK3 while preserving stock image usage on GTK2.
Switched menu icon creation to the shared GTK3 mapping helper.
This solves the issue where the parent dialog is closed and then
the child dialog is used.
This is however only a partial fix:
- Many other dialogs throughout the codebase do not currently have
parent windows and need to be refactored.
- Not all window managers respect modal so users can still trigger
bugs. We can be more defensive against this but it requires more
refactoring.
Closes#2686
- Fixes#314
- Adds file extensions to sound and image browsing
- Some options no longer default to our config dir
- Always add a shortcut to our config dir
- Remove broken 'last_dir' functionality, gtk already knows recent
