Introduced a servlist table-attach helper and applied it across servlist UI attachments to keep GTK_FILL/GTK_EXPAND confined to GTK2-only paths while setting GTK3 alignment/margins explicitly.
Added GTK3 icon-name macros and applied them to tab menu/search button icon usage in maingui.c, keeping GTK2 stock fallbacks intact.
Introduced GTK3 icon-name helpers and macro splits for server list buttons/connect controls in servlistgui.c.
Tightened GTK2/GTK3 icon macro separation in sexy-spell-entry.c.
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.
Applied gtk_box_set_homogeneous() in GTK3 branches where the GTK2 code requested homogeneous layout (e.g., dialog hboxes).
Updated remaining helpers and setup/preferences UI box constructors (including the shared mg_box_new helper) to follow the same GTK3/GTK2 branching approach consistently across src/fe-gtk/
Updated setup color selection and styling to use RGBA-aware GTK3 overrides/CSS while preserving GTK2 behavior in guarded paths.
Switched tree view color models/renderers and other palette consumers (user list, notify, DCC, menus, spell entry, input style) to RGBA-aware types/properties with shared RGB16 conversion usage.
Updated main GUI layout construction to use mg_box_new for topic bars, text areas, meters, search/entry bars, dialog buttons, and generic tabs to keep GTK3-friendly box creation consistent while preserving GTK2 behavior.
Switched the GTK frontend build logic to select GTK2/GTK3 dependencies and emit corresponding preprocessor defines.
Added GTK3 GtkGrid/alignment handling and GTK3 GtkBox replacements for the channel list controls while preserving GTK2 table behavior behind guards.
Switched the ban list layout to use GtkGrid under GTK3 with GTK2 table fallback for checkbox placement.
Updated main GTK UI layouts to use GTK3 GtkGrid/GtkBox and alignment/attachment logic (quit dialog, topic bar, search/entry, chanview placement, main window table) while keeping GTK2 behavior via HAVE_GTK3 guards.
- Replaced the dark mode checkbox with an Auto/Dark/Light color mode selector and ensured palette edits use the resolved mode.
- Applied the resolved color mode consistently across palette saving and GTK styling in the user list and channel tree/theme application paths.
- Added a Cairo surface → RGBA pixbuf conversion helper that unpremultiplies ARGB32 data for GTK2 compatibility while keeping window snapshots Cairo-based.
- Updated window snapshotting to use the new Cairo surface conversion instead of gdk_pixbuf_get_from_surface
- Updated xtext palette APIs to accept internal color arrays directly for rendering setup.
- Wired xtext palette creation through UI entry points to use the new palette helper when constructing or refreshing text views.
-Replaced GtkStyle application in the channel tree view with explicit base/text/font modifications to avoid style attach/detach issues on teardown.
-Updated user list styling to apply the font directly instead of setting a shared GtkStyle instance.
-Switched color button updates to use background modifications instead of creating per-button styles, reducing detach warnings on shutdown.
- Updated GtkXText to track the draw window and use a pixmap-to-surface helper for Cairo contexts, avoiding drawable references in the struct and rendering flow.
- Added a Cairo helper for capturing window-backed surfaces and used it when blitting during scrolling, fixing the build break from the removed drawable helper.
Added cairo surface tracking and context creation helpers for xtext rendering, including state initialization for the new draw surface field.
Replaced GdkPixmap-based offscreen text buffering with cairo surfaces and routed rendering/underline/strikethrough operations through the cairo context helper.
Replaced GDK source helpers in the text rendering pipeline with Cairo surface/color helpers for lines, backgrounds, and blits.
Updated render sizing to use window dimensions and switched window copy paths to Cairo surfaces.
winuser.h should never be included directly. windows.h should be included instead.
This fixes a critical build issue added in c5d47fc which makes all MinGW builds fail.
See #2403.
It is an odd binding that conflicts with typical behavior
where shift click selects multiple items and there is
already the middle click shortcut to close tabs quickly.
Closes#918
