How to get screen width and height in cell units?

Hi,

I am writing a plugin which adds Windows onto a given screen.

I am trying to get the dimensions of the screen in cell units (e.g 17 x 8 cells), so I can set the window's size accordingly

Things I tried:
ScreenContents
Root()["ShowData"]["UserProfiles"]["Default"]["ScreenConfigurations"]["Default"]["ScreenContents"]["ScreenContent 1"]

It has these properties:

[Int16 REQUESTEDW] = [<18>]

[Int16 REQUESTEDH] = [<7>]

But these number represent the current content's total size, not the screen size.
(Meaning that if there is a window of size 5x5 starting at (0,0) then we would have:
[Int16 REQUESTEDW] = [<5>]

[Int16 REQUESTEDH] = [<5>]

GraphicsRoot

Looking at GraphicsRoot

Root()["GraphicsRoot"]["PultCollect"]["Pult 1"]["DisplayCollect"]["Display 1"]

It has the MA3 Window size and position, and it has the SCALERATIO,
So I could theoretically calculate from the pixels, how many cells there are.
But this seems an overkill...


Any suggestions?

I solved it like this:
(Code snippet written in TypeScript)
It pretty robust.

/**
 * Get the window area size in cells.
 * More percisly, it return the size in whole-cells that fit in the screen.
 * (Meaning that there could be 0.5 a cell extra)
 * 
 * This takes into consideration wether the cmdBar, viewBar, encoderBar or cmdLineBar are shown or not,
 * and also works for different scaleRatios.
 */
function getWindowAreaSize(displayHandle: DisplayHandle) {
  const rows: any[] = (displayHandle as any)[1].Children()
  const columns: any[] = (displayHandle as any)[2].Children()
  const windowAreaSizePx = {
    // column 0 is the CmdBar, column 2 is the viewBar
    w: columns[1].Get("REALSIZE"), 
    // For some reason the sum of rows 0 and 1 gives us the window area height
    // row 2 is the cmdLineBar, row 4 is the encoderBar
    h: rows[0].Get("REALSIZE") + rows[1].Get("REALSIZE") 
  }
 
  return {
    w: Math.floor(windowAreaSizePx.w / 100),
    h: Math.floor(windowAreaSizePx.h / 100)
  }
}

But your solution is much better (not a hack like mine) , you strike again !
How do you get these insights?
I was looking at the children of the Display Object, and didn't dig deep enough.

So the UiScreen is here:
Root()["GraphicsRoot"]["PultCollect"]["Pult 1"]["DisplayCollect"]["Display 1"]["ScrollIndicatorBox"]["ScreenScroll"]["ScrollBox"]["UiScreen"]

Thanks again.
