From 000b305eccb8d732aa2bde5f4b2f126c23e574cf Mon Sep 17 00:00:00 2001 From: Markus Ongyerth Date: Tue, 17 Apr 2018 19:09:42 +0200 Subject: backend/libinput: Manage tablet tool livetimes This adds the management code to manage tablet tools lifetimes from libinput. It follows the suggestion made in the tablet-unstable-v2.xml to destroy tablet_tools once all tablets that it got into contact with were removed from the system. This is implemented via a refcount. If a tool is *not* unique, it will be destroyed on proximity out. This is libinput specific and mentioned in libinput docs that tools will not be found again, so we shouldn't keep a reference to them. Also they can't be on other tablets as well, because they cannot be tracked. The naming in this commit is a bit off (to not break things). The wlr names stay the same, tablet_tool is the libinput_device with capaiblity LIBINPUT_DEVICE_CAP_TABLET_TOOL which is more akin to "tablet" in the tablet-unstable-v2 protocol. The struct that corresponds to the tablet_tool in tablet-unstable-v2 is called tablet_tool_tool, a rename should be done at some point in the future. --- include/backend/libinput.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include/backend') diff --git a/include/backend/libinput.h b/include/backend/libinput.h index f0928133..6ecdf44f 100644 --- a/include/backend/libinput.h +++ b/include/backend/libinput.h @@ -67,6 +67,7 @@ void handle_touch_cancel(struct libinput_event *event, struct wlr_tablet_tool *create_libinput_tablet_tool( struct libinput_device *device); +void wlr_libinput_tablet_tool_destroy(struct wlr_input_device *device); void handle_tablet_tool_axis(struct libinput_event *event, struct libinput_device *device); void handle_tablet_tool_proximity(struct libinput_event *event, -- cgit v1.2.3
