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).
Replaced the GTK3 G_DECLARE_DERIVABLE_TYPE usage with explicit GtkXText typedefs/macros to keep the instance struct visible in GTK3 builds and avoid missing member errors.
Switched GtkXText and CustomList implementations to G_DEFINE_TYPE/G_DEFINE_TYPE_WITH_CODE and preserved parent chaining behavior
Added GTK3/GTK2 conditional type declarations for GtkXText while restoring the legacy macro block for GTK2 builds.
Restored GTK2-friendly typedefs/macros and parent field naming for CustomList alongside GTK3 G_DECLARE_DERIVABLE_TYPE usage.
Restored GTK2-friendly typedefs/macros and parent field naming for SexySpellEntry while keeping GTK3 declarations intact.
Restored legacy RemoteObject typedefs and GType macros in the D-Bus plugin to keep GTK2 builds from seeing incomplete types or missing fields/macros.
Added a shared cleanup helper plus GTK2 destroy/GTK3 dispose handlers with correct parent chaining for cleanup parity across GTK versions.
Updated class initialization to register GTK3 dispose or GTK2 destroy handlers with appropriate object class setup.
- 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.
- Updated the xtext renderer to accept Cairo background surfaces and dropped the GtkStyle attach during realize to keep rendering Cairo/Pango-focused.
- Switched background surface ownership and cleanup to use cairo_surface_t across the shared state and settings update path.
- 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.
Similar to a GtkTextView if you double click you enter word selection mode
and if you triple click you enter line selection mode.
Allowing you to drag and select more than a single character.
Closes#1108
* Rework multiline logic to use a GSList, not an array
* Remove all multibyte booleans; everything is potentially multibyte
- Except for gtk_xtext_get_word(), which needs special attention
* Enhance pango work for bold and italics (attr_list -> attr_lists[4])
* Enhance gtk_xtext_strip_color () to save bold, italics info
* Involve emphasis information in all pixel-width calculations
* Rework find_x () to account for emphasis info in widths
Closes#891Fixes#872
Xtext's transparency barely worked on windows, didn't work on any modern
linux wm and used fake transparency.
This uses gtk's built in window opacity that works on more systems and
is real transparency.
Text area only transparency may return with a transition to cairo, if it
works on Windows.
Text events allow %Cfg,bg as decribed in "Theming" on
https://hexchat.readthedocs.org/en/latest/appearance.html?#theming
That section describes mIRC colors 0-15 and local colors 16-31, but
when selecting background colors, the 9 special internal colors are
extremely useful, like %C20,33 will do bright red on the selected
text background color.
As the documentation is on-line, this patch has no doc-change.
Ideally, the color-codes should show in the colored squares in the
preferences color-dialog just as with colors 0-31
