From 2f1fd8072673b1824f37759e14f5388d7a87fb5c Mon Sep 17 00:00:00 2001 From: Ian Fan Date: Fri, 12 Oct 2018 21:14:52 +0100 Subject: [PATCH] swaybar: show hidden bar on key event Since wayland does not currently allow swaybar to create global keybinds, this is handled within sway and sent to the bar using a custom event, so as not to pollute existing events, called bar_state_update. --- include/ipc.h | 3 +++ include/sway/config.h | 1 + include/sway/ipc-server.h | 1 + include/swaybar/config.h | 1 + sway/config/bar.c | 2 ++ sway/input/keyboard.c | 28 ++++++++++++++++++++++------ sway/ipc-server.c | 18 ++++++++++++++++++ swaybar/ipc.c | 19 ++++++++++++++++++- 8 files changed, 66 insertions(+), 7 deletions(-) diff --git a/include/ipc.h b/include/ipc.h index a3f60e19..9063b933 100644 --- a/include/ipc.h +++ b/include/ipc.h @@ -30,6 +30,9 @@ enum ipc_command_type { IPC_EVENT_BINDING = ((1<<31) | 5), IPC_EVENT_SHUTDOWN = ((1<<31) | 6), IPC_EVENT_TICK = ((1<<31) | 7), + + // sway-specific event types + IPC_EVENT_BAR_STATE_UPDATE = ((1<<31) | 20), };
