Pick the W32 API for possible deadkey+<something> combinations and prefer these to other sources of deadkey combos. Specifically, if W32 API supports at least one combo for a particular deadkey, only use that data and do not attempt to do other, unsupported combinations, even if they make sense otherwise. This is needed to, for example, correctly support US-International keyboard layout, which produces a combined character for <' + a> combo, but not for <' + s>, for example. This is achieved by stashing all the deadkeys that we find in an array, then doing extra loop through all virtual key codes and trying to combine them with each of these deadkeys. Any combinations that produce a single character are cached for later use. In GTK Simple IM context, call a new GDK W32 function to do a lookup on that cached combination table early on, among the "special cases" (which are now partially obsolete). A limitation of this code is that combinations with more than one deadkey are not supported, except for combinations that consist entirely of 2 known deadkeys. The upshot is that lookups should be relatively fast, as deadkey array stays small and the combination tree stays shallow. Note that the use of ToUnicodeEx() seems suboptimal, as it should be possible to just load a keyboard library (KBD*.DLL) manually and obtain and use its key table directly. However, that is much more complicated and would result in a significant rewrite of gdkkeys-win32. The code from this commit, though hacky, is a direct addition to existing code and should cover vast majority of the use-cases. https://bugzilla.gnome.org/show_bug.cgi?id=569581 |
