TextBox : remark about Numeric + Angle FilterStyle

When the FilerStyle of a TextBox is set to Numeric or Angle Units Filter, the TextBox does 2 things :
- filtering invalid caracters
- converting values onto the default numeric format (set by _UNITS) when leaving it (OnKillFocus)

So FilterStyle automatically converts the value OnKillFocus, with something like :
(distof .. (getvar "LUNITS")) and (angtof .. (getvar "AUNITS"))

I don't know if there are reason to this 2nd behavior, but I'm not sure it's relevant.
In ACad you can write "1/8" even if your units system is set to Decimal (or you can write "0.12r" even if .. Degree), and I think that if you write "1/8" you don't want to recover "0.125"..
Personnaly I don't use it for this reason. I replace it by a OnKillFocus function that simply erase the string of the TextBox if the value is incorrect according to the general format, indeed if (distof .. (getvar "LUNITS")) = 0 (so on the other hand there is no more "0"...)

So, I was wondering if this remark should be a feature request or not ?

Those filter styles are actually implemented by Autodesk, so it wouldn't be possible to change them without recreating them in OpenDCL.

Quite interesting. Are these own classes of textboxes? Where are these defined?

The ObjectARX API exposes derived versions of the MFC edit control and combo controls that implement these filters via predefined filter styles. Here is a brief description of the four filter styles:
