From 9b8249c350a499bb65e50741e8a45e5575ac7d18 Mon Sep 17 00:00:00 2001 From: Brian Ashworth Date: Wed, 13 Feb 2019 14:32:47 -0500 Subject: seatop_move_tiling: use tab/stack parent not self When moving a descendant of a tabbed or stacked container, it is possible for the target node to be the node being moved. This causes a segfault in `handle_finish` since the node will be detached and then attempted to be attached to it own parent, which is NULL due to the detach. In this case, the target node should not be set to the node being moved, but the parent of the node. This also allows for a descendant of a tabbed or stacked container to be dragged out of the tabs/stacks and to be a sibling of the tabbbed/stacked container, which was not previously possible. --- sway/input/seatop_move_tiling.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'sway/input') diff --git a/sway/input/seatop_move_tiling.c b/sway/input/seatop_move_tiling.c index 8b541f80..422a4aa2 100644 --- a/sway/input/seatop_move_tiling.c +++ b/sway/input/seatop_move_tiling.c @@ -150,6 +150,9 @@ static void handle_motion_postthreshold(struct sway_seat *seat) { } if (edge) { e->target_node = node_get_parent(&con->node); + if (e->target_node == &e->con->node) { + e->target_node = node_get_parent(e->target_node); + } e->target_edge = edge; node_get_box(e->target_node, &e->drop_box); resize_box(&e->drop_box, edge, DROP_LAYOUT_BORDER); -- cgit v1.2.3
