Comment 2 Joel Majano CLA 2021-12-13 11:19:40 EST 
With this patch, ToolTip Balloon functionality is disabled until replacement functions can be found for the sea of them used in ToolTip.configure(). In the meantime, an error will be printed stating that configure() is not working and that ToolTip Balloon functionality is not available.
Comment 4 Joel Majano CLA 2021-12-15 12:19:16 EST 
When ToolTip is selected visible, and "Show in tray" is also selected, a GTK3 only function gets called. Currently investigating but since StatusIcon was removed in GTK4 replacement is technically possible in X11, but not in Wayland without the use of external libraries. See https://discourse.gnome.org/t/what-to-use-instead-of-statusicon-in-gtk4-to-display-the-icon-in-the-system-tray/7175 for more details. 

Also, GtkPopover will be explored as a replacement for ToolTips with SWT.BALLOON style since their visual representation is similar.
