comparison os2/dw.c @ 203:e0beea487e8f

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Added the basics for scrollbar thumb size on OS/2, and dw_main_iteration() which runs a message loop until it handles one message and returns. So other languages can run message loops and call this function internally.
