From 51b9883ea0201195ed7c151175725c926c94bd47 Mon Sep 17 00:00:00 2001 From: Dominique Martinet Date: Mon, 4 Jun 2018 08:31:27 +0900 Subject: seat: allow clients to bind to seat multiple times This lets clients bind to a seat multiple times by re-using the existing wlr_seat_client whenever a duplicate request happens. Previously, an independant wlr_seat_client would be created and only events from one would be processed. Fixes #1023. --- include/wlr/types/wlr_seat.h | 2 +- types/data_device/wlr_drag.c | 2 +- types/seat/wlr_seat.c | 74 +++++++++++++++++++++++++++++--------------- 3 files changed, 51 insertions(+), 27 deletions(-) diff --git a/include/wlr/types/wlr_seat.h b/include/wlr/types/wlr_seat.h index f4840c89..5e04003d 100644 --- a/include/wlr/types/wlr_seat.h +++ b/include/wlr/types/wlr_seat.h @@ -13,11 +13,11 @@ * managed by wlr_seat;
