Clicking on other monitor is like clicking on stackline of main monitor

[kiryph]

I have two screens:

+--------++----------------+
|w1      ||Indic.1 stacked |
|single  ||Indic.2 w1 & w2 |
|window  ||                |
|        |+----------------+
|        |
+--------+

When I click on the left screen in the upper left corner, it is like I would click on the right screen on the indicator icons of stackline.

I have added another log command to a relevant section of the code:

    end

    return table.unpack(

The output is

2022-03-31 18:22:13: 18:22:13     window: absoluteToLocal hs.geometry.point(23.1962890625,76.979263305664)

The click coordinates are modified and become coordinates of the main screen. IMHO this should not happen.

The change clickedScreen:absoluteToLocal(p) has been added in commit b02ffe763b2cdf3a8b73255937bea49f071e6bbd, an attempt to fix another issue #62

FYI for anyone else with this issue:

To get around this for now I've commented out the logic in function Stack:getWindowByPoint(p) that handles negative coordinates.

Two aspects

1. Determine current screen, skip indicator windows which are not on the current screen:

   return table.unpack(
         u.filter(self.windows, function(w)
          local indicatorFrame = w.indicator and w.indicator:canvasElements()[1].frame
   -          if not indicatorFrame then return false end
   +          if not indicatorFrame or w.screen:id() ~= clickedScreen:id() then return false end
          return p:inside(indicatorFrame) -- NOTE: frame *must* be a hs.geometry.rect instance
      end)
   )

2. If you have three displays the criteria that only negative coordinates have to be transformed with absoluteToLocal(p) is not true.

   Also positive coordinates can be outside of the primary display. Here my geometry according to yabai -m query --displays:

Please review a typo (clickedScren) !!.. Its work to me!! thanks

if not indicatorFrame or w.screen:id() ~= clickedScren:id() then return false end
