From a82f5750ded81dd1789c868f0e8f233c5b79b85a Mon Sep 17 00:00:00 2001 From: Michael Stapelberg Date: Sun, 18 Sep 2011 17:00:29 +0100 Subject: [PATCH] Bugfix: Avoid out of bounds coordinates when moving floating windows (Thanks eeemsi) This commit makes the coordinates proportional when moving floating windows. That is, if you have a window at the bottom of your 1920 px monitor and move it to your 800 px monitor, it will be at the bottom of the 800 px monitor (and not out of bounds). --- src/con.c | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) diff --git a/src/con.c b/src/con.c index 91970672..148f7822 100644 --- a/src/con.c +++ b/src/con.c @@ -613,10 +613,19 @@ void con_move_to_workspace(Con *con, Con *workspace, bool fix_coordinates, bool * to the coordinate space of the correct output */ if (fix_coordinates && con->type == CT_FLOATING_CON) { DLOG("Floating window, fixing coordinates\n"); + /* First we get the x/y coordinates relative to the x/y coordinates + * of the output on which the window is on */ uint32_t rel_x = (con->rect.x - source_output->rect.x); uint32_t rel_y = (con->rect.y - source_output->rect.y); - con->rect.x = dest_output->rect.x + rel_x; - con->rect.y = dest_output->rect.y + rel_y; + /* Then we calculate a fraction, for example 0.63 for a window + * which is at y = 1212 of a 1920 px high output */ + double fraction_x = ((double)rel_x / source_output->rect.width); + double fraction_y = ((double)rel_y / source_output->rect.height); + DLOG("rel_x = %d, rel_y = %d, fraction_x = %f, fraction_y = %f, output->w = %d, output->h = %d\n", + rel_x, rel_y, fraction_x, fraction_y, source_output->rect.width, source_output->rect.height); + con->rect.x = dest_output->rect.x + (fraction_x * dest_output->rect.width); + con->rect.y = dest_output->rect.y + (fraction_y * dest_output->rect.height); + DLOG("Resulting coordinates: x = %d, y = %d\n", con->rect.x, con->rect.y); } else DLOG("Not fixing coordinates, fix_coordinates flag = %d\n", fix_coordinates); /* If moving to a visible workspace, call show so it can be considered -- 2.39.5
