<div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="im"> </div>Hi Scott, to me the commit message seems wrong compared to the change. When you talk about sending and clients, and do not prefix the title with window, I assume you are patching the server to not send events to clients. If I understood right, this patch would be better described as window: ignore modifier key events Toytoolkit apps should not even try to track modifier state, it is already tracked in the modifier mask. Am I missing something? Thanks, pq </blockquote></div> Hi, thanks for your comments. I think perhaps this patch might not be the right way to do what it's intended to, which is avoid clients receiving mismatched pairs of modifier events when a grab is used. e.g. if a client receives a <modifier> down event and subsequently a grab is initiated, the client never gets the <modifier> up event when the grab is complete.
