wxCocoaDialog v0.3

http://code.google.com/p/wxcocoadialog/

wxCocoaDialog is an multi-platform port of the CocoaDialog application 
for OS X, that allows the use of common GUI controls such as file 
selectors, text input, progress bars, yes/no confirmations and more with 
a command-line application. It is ideal for use in shell and Ruby 
scripts (or Perl, or Python, or... etc).

Since the use of the original CocoaDialog is very common in shell 
scripts on Mac OS X, the port makes it possible to to also use such 
scripts on Linux and Windows (with cygwin).

Implemented Controls

As of wxCocoaDialog v0.3, the following controls are implemented:

     * inputbox
     * standard-inputbox
     * secure-inputbox
     * secure-standard-inputbox
     * dropdown
     * progressbar
     * textbox
     * msgbox
     * ok-msgbox
     * yesno-msgbox

The wxWidgets port was originally created for use in the e text editor ( 
http://e-texteditor.com ), which supports TextMate bundles and can be 
extended with shell scripts (through cygwin). Since it could be useful 
in a lot of other contexts than e, it was released to the community as 
open source.
