Sandro Martini closed PIVOT-343.
--------------------------------
Resolution: Won't Fix
The current behavior is enough (at least in current tests).
> Handle Control Characters in Input Fields
> -----------------------------------------
>
> Key: PIVOT-343
> URL: https://issues.apache.org/jira/browse/PIVOT-343
> Project: Pivot
> Issue Type: Improvement
> Components: wtk
> Reporter: Sandro Martini
> Priority: Minor
> Fix For: 2.0
>
>
> In TextInput (or at least in TextArea, then possibly in any other component
> that accept input form the user) could be useful to have a property to set
> what to do with Control Chars, like in dot Net components.
> This is important for example with some applications reading data from
> instruments (for example BarCode Scanners), where usually at the end of any
> code read will be appended a CR LF as a marker, and in this case these chars
> have to be accepted in the field but not displayed.
> The default behavior should be to filter them out in all components (but not
> in multi-line components, like TextArea), but if the filtering is disabled
> (maybe with a dedicated style property) we could use another style property
> to set the desired formatting (by default nothing, or maybe a given char like
> space, etc).
> So what do you think on a style like "escapeControlCharacters" to control the
> display part, with some flag values, like "space", "none" or "null", etc ?
> And another style like "filterControlCharacters" by default true (remove any
> non printable char, but in a i18n context could not be so simple to know if a
> char is displayable, right ? or maybe we could have here a regexp but could
> be too heavy ... ideas ?) and if false it keep all chars as given.
