William, The error means that the XUL should be opened with a call to window.openDialog() - which takes the arguments:
window.openDialog(filename, windowtitle, windowoptions, ...) where ... is turned into arguments[0], arguments[1], etc. So the XUL probably has an onload handler that calls some javascript that expects to be able to use arguments[0] as a certian type of interface.... If you look at printdailog.js line 366, you should be able to tell what it is trying to QI arguments[0] into, and by that you should know what you need to pass in window.openDialog as argument 0. -Adam William JOYE wrote: > Hello, > > I would like to use my own printdialog box.
