Hi Christopher. Christopher escribió:
I have attached a SelectFilePanel class from Kosmo source code. I think you have only to adapt the I18N messages to make it work. If you find any problem with it tell me about.1a. Is there a way to input a filename other than just a TextField? Specifically I want to have a TextField with an icon next to it that when clicked will bring up a file browser similar to the "open file" dialog.
Hope this helps. Regards, -- Sergio Baños Calvo Jefe de desarrollos Sistemas Abiertos de Información Geográfica, S.L. (SAIG S.L.) Tlfno. móvil: 685005960 Tlfno. fijo: (+34) 954788876 E-mail: [EMAIL PROTECTED]
