[Closed] Radiobuttons : #offsets parameter rules

whatever solution you find, I bet it will not be correct and unambiguous … which I will confirm with the next snippet

maybe this could explain
the only thing should be concerned is every character has itself‘s length , so ‘L’ and ‘R’ have different length

I forgot to say…

I have no idea how it works in every case. I tried but didn’t find any common logic.

all offset based on the original postion , which based on the sorting of dialog , the one control offsetting , the others below it would be affected
when offset, any one in one line and behind would not offset , the other lines would
when the offset one have other controls in one line , the below lines wouldn’t offset to up , if the offset one is the only one in that line , the below could offset to up but can’t offset out of the dialog , the most x-offset < 0 is set them to the first line ‘s y-pos

i think this is the all rules

Now, when you know the rules, answer:

We have four-buttons group of radio buttons in one row. How much will the third element be offset from its original position if only the fourth element has a specified offset of [100,0]?

	radiobuttons rb1 labels:#("1","2","3","4") columns:4 align:#left offsets:#([0,0],[0,0],[0,0],[0,0])
	radiobuttons rb2 labels:#("1","2","3","4") columns:4 align:#left offsets:#([0,0],[0,0],[0,0],[100,0])

if you mean the 3rd of rb2 offset from the 3rd of rb1 , for radiobutton , offset was limited in it’s own cell ， then x-offset = 100 will expand left of 4th , and other 3 expand ringt , all 100 px , if all items’ original length are 50px , then original postion is [ 0 , 0+50 , 50+50 , 50+50+50 ] , after offset will be [0 , 0+50+100 , 0+50+100+50+100 ，0+50+100+50+100+50+100+100] ，so 3rd from 100 ->300

try(destroydialog rol) catch()
rollout rol "Test Rollout" width:700
(
	local lbs = #("1","2","3","4")
	
	radiobuttons rb1 labels:lbs columns:4 align:#left
	radiobuttons rb2 labels:lbs columns:4 align:#left offsets:#([0,0],[0,0],[0,0],[100,0])

	label info align:#left enabled:off offset:[0,8]

	on rol open do
	(
		pp = for k=1 to 4 collect
		(
			p = windows.getWindowPos rb1.hwnd[k]
		)
		
		ss = stringstream ""
		dd = for k=1 to 4 collect
		(
			p = pp[k]
			d = windows.getWindowPos rb2.hwnd[k]
			
			dx = d.x - p.x 
			format "%(%,%) " dx p.w d.w to:ss

			d
		)
		info.text = ss as string
	)
)
createdialog rol

There’s a RadioControl::compute_layout method in Maxscrpt.dll that is likely related to this.

As far as the few test I’ve done for the example given by @denisT, I came up with this very simple formula:

Control pixel position = (control index * maximum offset) + control offset
Control index is 0 based.

This formula seems to work consistently for this specific example, radio buttons, left align. Didn’t test it with other configurations.

So, for this #([0,0], [0,0], [0,0], [100,0]), the position of the third control should be 200px.

Control index = 2
Maximum offset = 100
Control offset = 0
(2*100)+0 = 200
