I'm trying to figure out if there's a relatively easy way to edit an array of primitive numeric values (i.e. int/double) in a control similar to your ThicknessEditBox, SizeEditBox, RectEditBox, Int32RectEditBox, CornerRadiusEditBox, etc. i.e. it would have (some number of) numeric values separated by commas, with a spinner that lets you alter the currently-selected value. Ideally the array length wouldn't have to be fixed; i.e. it could be used to edit the 9 values in a length-9 array, etc.
I feel like this is likely possible, and that if so it probably starts with a PartEditBox, but I keep getting lost when looking through the sample code. Any pointers you could give would be appreciated :)
