We used to use .allowNaN = true in previous versions of Actipro PointEditBox to make it so users knew that x or y was different.
In our case, we were using it in a property grid, and if multiple objects were selected, if they had different x or y values, we set that value to NaN. The editor would look like this (object #1 was at (1,1) while object #2 was at (1,2)):
Position [ 1, NaN ]
It made it semi-clear to the user that 1 was a shared value between the two objects, while NaN meant that they had different values.
At some point in 2017, you removed the ability to use allowNaN in PointEditBox. Do you have an alternative for me?
I just want to set a value for either x or y that shows in the editor that is not a number, but still changable to a number. Something like (123, ??) or (123, --).
You allowNull, but only on the entire point, not the individual point .x .y.
