From 0553e75b53137e6d509b6e336c21586f2b75d527 Mon Sep 17 00:00:00 2001 From: Dmitri Kourennyi Date: Fri, 22 Mar 2019 17:18:21 -0400 Subject: [PATCH] Implement handling of short_text field of i3 input protocol. Matches i3bar behavior of setting all blocks to use the short_text if the full text width does not fit. --- swaybar/render.c | 174 +++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 170 insertions(+), 4 deletions(-) diff --git a/swaybar/render.c b/swaybar/render.c index 116cc595b..faf175096 100644 --- a/swaybar/render.c +++ b/swaybar/render.c @@ -144,16 +144,21 @@ static void i3bar_block_unref_callback(void *data) { static uint32_t render_status_block(cairo_t *cairo, struct swaybar_output *output, struct i3bar_block *block, double *x, - bool edge) { + bool edge, bool use_short_text) { if (!block->full_text || !*block->full_text) { return 0;
