Subject: move.c: Fix move_to_output_directed problems
X-Git-Tag: 4.16~13^2~1
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=9380a75186f8d2adcf572a3741168f12351faa9b;p=i3%2Fi3

move.c: Fix move_to_output_directed problems

- Use workspace_show that correctly updates _NET_CURRENT_DESKTOP, warps
mouse.
- Use TAILQ_INSERT_TAIL only for focus_head. Focus order is not related
to direction.
- Call con_focus only if con was focused before. See testcase for
directional move with command criteria.
- Correct first call of move_to_output_directed in tree_move which
didn't call ipc_send_window_event("move", con) and
ewmh_update_wm_desktop().
- Don't produce events when the move doesn't happen. Correct
276-ipc-window-move.t as well.
