Pashua ist a tool for creating native Aqua dialog windows for Perl, PHP, Tcl, Python, Ruby, Rexx and shell scripts as well as AppleScript. The GUI elements which can be used for such dialogs include text input fields (single-line and multi-line), checkboxes, radiobuttons, combo boxes, popup menus, open panels or buttons. Moreover, it's possible to embed images or PDFs. Any data submitted from the dialog will be passed on to the calling script, which can (of course) use it for anything.
To describe the dialog window, Pashua uses a very simple syntax. All the tedious details such as positioning the elements, calculating the window size etc. are handled automatically by Pashua, thus you can fully concentrate on your application.
