Re: printdialog error

OK. Now, I would like to call xull with the openDialog function and the 2
parameters but and I cannot create them correctly.
How can I create the 2 arguments (nsIPrintSettings object and the container
for return value)? Here is the parameters and a few code
...
// param[0]: nsIPrintSettings object
// param[1]: container for return value (1 = print, 0 = cancel)
var ps = window.arguments[0].QueryInterface(gPrintSetInterface);
if (ps != null) {
gPrintSettings = ps;
paramBlock =
window.arguments[1].QueryInterface(Components.interfaces.nsIDialogParamBlock
);
} else {
var suppsArray =
window.arguments[0].QueryInterface(Components.interfaces.nsISupportsArray);
if (suppsArray) {
var supps = suppsArray.ElementAt(0);
gPrintSettings = supps.QueryInterface(gPrintSetInterface);
if(!gPrintSettings) {
return;
}
supps = suppsArray.ElementAt(1);
paramBlock =
supps.QueryInterface(Components.interfaces.nsIDialogParamBlock);
if(!paramBlock) {
return;
}
} else {
return;
}
}
// default return value is "cancel"
paramBlock.SetInt(0, 0);
....
