Keyman Build Summary / Summarize build status checks (push) Waiting to run
Clean up the keyboard refresh process. Keyman COM API will post a `wm_keyman_refresh`, `KR_REQUEST_REFRESH` message when changes have been made to the list of installed keyboards (or some other keyboard-related settings change). Keyman Engine (any arch) will handle this message, in any process, and post a message to the master controller (keyman.exe, TfrmKeyman7Main), `wm_keyman_refresh`, `KR_PRE_REFRESH`. Keyman Engine (keyman32) will handle _this_ message in the master controller thread context, and increment the global refresh tag. It also asks the other architecture host process(es) to update their global refresh counter to the same value (by posting `wm_keyman_refresh`, `KM_PRE_REFRESH` to those process(es).) This refresh tag is then compared on-demand in each thread to the thread's current refresh tag value, when a keyboard activation is received, on set focus, or on a keystroke, and the keyboard list is refreshed at that point. This means that keyboard installation no longer triggers a large amount of activity reloading all the keyboards on all windowed threads, but rather they will gradually reload as the user interacts with them. It also fixes #15333, which related to having threads with only child windows -- that is, that were parented by top-level windows from other threads -- which thus never received the global broadcast in the earlier design. For example, VSCode, Notepad in Win11, Chrome. Fixes: #15333
