Re: [Pharo-users] Phobos: Using open and save dialogs

      It's Ok I think I've got it.

You can add a method like this to your main.js:

function doFileOpen() {
  /* See:
http://developer.mozilla.org/en/docs/XUL_Tutorial:Open_and_Save_Dialogs */

  var nsIFilePicker = Components.interfaces.nsIFilePicker;
  var fp =
Components.classes["@mozilla.org/filepicker;1"].createInstance(nsIFilePicker);

  fp.init(window, "Open File", nsIFilePicker.modeOpen);
  fp.appendFilters(nsIFilePicker.filterText | nsIFilePicker.filterAll);

  var res = fp.show();
  if (res == nsIFilePicker.returnOK) {
    var thefile = fp.file;
    return(thefile.leafName);
    // --- do something with the file here ---
  }  
}

Then call it from pharo with an evaluateJS method - if you return the
filename from the javascript method pharo can pick it up:

MyPhobosComponent>>getFilename
|res|

	res:= self evaluateJS:'doFileOpen();'.

Of course, you could build the entire javascript method as a string in pharo
and call it using evaluteJS but it's simpler to put it into main.js as
deaing with embedded quotes is fiddly.
