Currently i3bar click events provide x and y coordinates relative to all monitors.
I've added coordinates relative to the current output.
+-----------+-----------+
| | i3bar |
| +-----------+
| HDMI-0 | DP-0 |
| 1920x1080 | 2560x1080 |
+-----------+-----------+
When you click in the top right corner of the DP-0,
i3bar will provide something like this:
{
"x": 4480,
"y": 10,
"output_x": 2560,
"output_y": 10,
}
This is useful for creating a rofi menu or something else.
rofi -show run -location 1 -xoffset ${I3_OUTPUT_X} -yoffset ${I3_OUTPUT_Y}
