<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">The big problem with textShouldChange (and thus the current implementation) is that it only allows YES or NO insert this string, you can't modify the string. No problem a single character, but if someone drags or paste let's say ATTAATAGATGAF then you would disallow that because it contains the F. What you want however is to allow it, but filter the F. <DIV>A solution in the context of what you had in mind would be to delegate the filtering to the controller in those methods that I override, which is easy to do and elegant.</DIV><DIV>Cheers,</DIV><DIV>Alex</DIV><DIV><BR><DIV><DIV>On 13-apr-2006, at 12:41, Koen van der Drift wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">On Apr 13, 2006, at 6:21 AM, Alexander Griekspoor wrote:</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV> <BLOCKQUOTE type="cite"><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">One exercise for the reader would be to add an "allowed_characterset" property, I've currently hardcoded the DNA characters, hence it doesn't work for filtering aa's.</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">I'm not sure how this fits with the bc classes, but I'll leave it up to koen to decide<SPAN class="Apple-converted-space"> </SPAN>if/how to implement all this.</DIV> </BLOCKQUOTE><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Well, eventually the BCSymbolSet needs to be used as a filter, probably through the controller (maybe using textShouldChange or something like that).</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">I'll have a look at your code later today, now I'm off to work soon.
