I make an extension that opens certain types of files with Google Docs Viewer.
I use the nsIURIContentListener to listen for specific MIME types, e.g.,
application/pdf.
I want to use a notificationBox to ask the User if they want to open that file
with Google Docs Viewer or not.
The problem is: If the User makes an right click on the file and open that in a
new window/tab, then the notificationBox should open in that window/tab but it
opens in the current Tab.
What code would I need to open the notificationBox in the right window/tab?
Sorry for my bad english!
What I've managed so far:
var gViewer = {
uriloader:
Components.classes["@mozilla.org/uriloader;1"].getService(Components.interfaces.nsIURILoader),
QueryInterface: function(aIID) {
if (aIID.equals(Components.interfaces.nsIURIContentListener) ||
aIID.equals(Components.interfaces.nsISupportsWeakReference) ||
aIID.equals(Components.interfaces.nsISupports))
return this;
throw Components.results.NS_NOINTERFACE;
},
register: function() {
this.uriloader.registerContentListener(this);
},
unregister: function() {
this.uriloader.unRegisterContentListener(this);
},
getPref: function(prefName, defaultValue) {
var prefService = Components.classes["@mozilla.org/preferences-service;1"]
.getService(Components.interfaces.nsIPrefBranch);
var prefValue = defaultValue;
try {
prefValue = prefService.getBoolPref(prefName);
} catch (e) {
}
return prefValue;
},
checkContentType: function(contentType) {
const sPrefPrefix = "extensions.gviewer.contenthandling.files.";
switch (contentType) {
case "application/pdf":
return this.getPref(sPrefPrefix + "pdf", false);
case "application/vnd.ms-powerpoint":
return this.getPref(sPrefPrefix + "ppt", false);
case "application/msword",
"application/vnd.openxmlformats-officedocument.wordprocessingml.document":
return this.getPref(sPrefPrefix + "doc", false);
default:
return false;
}
},
canHandleContent: function(contentType, isContentPreferred,
desiredContentType) {
return this.checkContentType(contentType);
},
isPreferred: function(contentType, desiredContentType) {
return this.checkContentType(contentType);
},
onStartURIOpen: function(uri) {
return false;
},
doContent: function(contentType, isContentPreferred, channel, contentHandler)
{
channel.QueryInterface(Components.interfaces.nsIChannel);
// get information about the request
var url = channel.URI.spec;
var protocol = channel.URI.scheme;
var notificationCallbacks = channel.loadGroup.notificationCallbacks;
var webNavigation =
notificationCallbacks.getInterface(Components.interfaces.nsIWebNavigation);
var website = webNavigation.currentURI.spec;
if (website.indexOf("docs.google.com") != -1) {
contentHandler = null;
return false;
}
if (protocol.toLowerCase().indexOf("http") != 0) {
contentHandler = null;
return false;
}
var stopFlags = Components.interfaces.nsIWebNavigation.STOP_ALL;
webNavigation.stop(stopFlags);
var notificationBox = gBrowser.getNotificationBox();
var notification = notificationBox.getNotificationWithValue("gDocMessage");
var message = "Open this file with Google Docs?"
if (notification) {
notification.label = message;
}
else {
var buttons = [{
label: "Yes",
accessKey: "",
callback: function() {
}
},{
label: "No",
accessKey: "",
callback: function() {
}
},{
label: "Don't ask me again",
accessKey: "",
callback: function() {
}
}];
const iconURL = "chrome://sendtogoogledocs/skin/question-16.png";
const priority = notificationBox.PRIORITY_INFO_LOW;
notificationBox.appendNotification(message, "gDocMessage",
null,
priority, buttons);
}
// handle the download
var viewOnlineURL = "http://docs.google.com/viewer?url="; +
encodeURIComponent(url);
var loadFlags = Components.interfaces.nsIWebNavigation.LOAD_FLAGS_NONE;
webNavigation.loadURI(viewOnlineURL, loadFlags, null, null, null);
return true;
}
};
window.addEventListener("load", function(event) { gViewer.register(event); },
false);
window.addEventListener("unload", function(event) { gViewer.unregister(event);
}, false);
