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.
Updated GTK3-specific palette color storage handling in DCC, notify, and user list views to align with HAVE_GTK3 guards.
Standardized setup color application and dialog logic to use HAVE_GTK3 branches for GTK3/GTK2 separation.
Updated GTK helper usages to reference the new ICON_* (and label) macros so GTK3 builds no longer pass stock IDs to button/icon helpers or dialogs, including banlist buttons, DCC windows, rawlog actions, notify dialog/buttons, pevent dialog buttons, tray menu items, and join dialog image helper usage.
Reused the palette foreground property macro for user list and DCC text renderers to match RGBA usage in GTK3 while keeping GTK2 behavior intact.
Aligned GTK2 setup color callbacks with PaletteColor and ensured RGBA parsing initialization in the palette helper.
Adjusted setup RGBA conversion fallback to explicit channel conversion when parsing fails.
Updated GtkCellRendererText foreground property handling for GTK2/GTK3 in user list, DCC list, and notify list rendering.
Switched user list and DCC tree view text columns to select the GTK3 foreground-rgba property (with GTK2 fallbacks) for cell renderer text colors.
Reused RGBA parsing for palette-backed color chooser defaults and clarified palette change tracking comments.
Parsed palette colors before initializing the GTK3 color chooser dialog to ensure RGBA normalization.
Switched GTK3 GtkCellRendererText foreground bindings to foreground-rgba with GTK2 fallbacks in user list, notify, and DCC views.
Generated GTK3 caret-color CSS using GdkRGBA string conversion instead of manual RGB math for input styling.
Simplified palette RGB16 parsing by building a GdkRGBA-compatible color string before parsing.
Updated GTK3 list-model color storage and GtkCellRendererText foreground properties to use RGBA values in the user list, notify list, and DCC views while retaining GTK2 behavior.
Copied palette RGBA values before initializing the GTK3 color chooser dialog to ensure RGBA usage on the GTK3 path.
Copy RGBA values from the GTK color chooser into palette entries for the setup dialog path.
Added RGBA-aware list-store color helpers and usage for userlist, notify, and DCC views to keep color handling consistent across GTK versions.
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.
This is the first step to build with GSEAL_ENABLE
setup.c uses a deprecated fontchooser,
chanview-tabs.c didn't like the conversion, and
I am waiting to do some work on xtext.c before
converting it.
