From 32cb631143fe9087d9d14e96f42a38f602369212 Mon Sep 17 00:00:00 2001 From: Ryan Dwyer Date: Thu, 4 Oct 2018 19:23:04 +1000 Subject: Give focus to another swaylock surface when output is disconnected * Have multiple outputs * Launch swaylock * Unplug an output (possibly has to be the last "connected" one) * The swaylock surface on the remaining output would not respond to key events This was happening because when the output destroys, focus was not given to the other swaylock surface. This patch makes focus be transferred to another surface owned by the same Wayland client, but only if input was inhibited by the surface being destroyed, and only if it's in the overlay layer. I figure it's best to be overly specific and relax the requirements later if needed. This patch removes a check in seat_set_focus_surface which was preventing focus from being passed from a layer surface to any other surface. I don't know of a use case for this check, but it's possible that this change could produce issues. --- sway/desktop/layer_shell.c | 36 ++++++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) (limited to 'sway/desktop') diff --git a/sway/desktop/layer_shell.c b/sway/desktop/layer_shell.c index e09282b2..269864d4 100644 --- a/sway/desktop/layer_shell.c +++ b/sway/desktop/layer_shell.c @@ -216,12 +216,48 @@ void arrange_layers(struct sway_output *output) { } } +static struct sway_layer_surface *find_any_layer_by_client( + struct wl_client *client, struct wlr_output *ignore_output) { + for (int i = 0; i < root->outputs->length; ++i) { + struct sway_output *output = root->outputs->items[i]; + if (output->wlr_output == ignore_output) { + continue; + } + // For now we'll only check the overlay layer + struct sway_layer_surface *lsurface; + wl_list_for_each(lsurface, + &output->layers[ZWLR_LAYER_SHELL_V1_LAYER_OVERLAY], link) { + struct wl_resource *resource = lsurface->layer_surface->resource; + if (wl_resource_get_client(resource) == client) { + return lsurface; + } + } + } + return NULL; +} + static void handle_output_destroy(struct wl_listener *listener, void *data) { struct sway_layer_surface *sway_layer = wl_container_of(listener, sway_layer, output_destroy); + // Determine if this layer is being used by an exclusive client.
