Switched the plugin GUI action buttons to GTK3 icon-name images with GTK2 stock fallbacks.
Added GTK3 icon-name mappings for menu entries, updated menu popups to gtk_menu_popup_at_pointer, and set GTK3 dialog button icons while preserving GTK2 stock 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.
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
- Removes need to check for malloc failure
- Removes need for NULL checks on free
- Adds checks for integer overflows
- Removes some extra memset calls
- Removes chance of mixing libc and glib malloc/free
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.
