Is it possible to change the operating system cursor with Electronjs?
When I use startDrag, for example, the cursor in macOS is the same as html drag; I wish to change that cursor to a custom one.
provide an icon
If you're talking about the event.sender.startDrag method that exists on incoming IPC messages in the main thread, then you can provide an icon property to that method's argument, like so:
event.sender.startDrag({
file: absPathToFileBeingDragged,
icon: DROP_ICON_PATH
})
Note that the Electron docs for startDrag say MacOS requires that you provide an icon. The docs also say icon can be a path to an image or an instance of NativeImage (which I assume means you can generate a bitmap in RAM and pass its handle without writing that bitmap to disk first).
In context, this might look like:
const DROP_ICON_PATH = Path.join(__dirname, 'custom-drag-out-icon.png')
ipcMain.on('drag-file-out-of-app', ( event, ...dataFromCaller ) => {
// ...do some work to locate or create the file the user will be dragging
event.sender.startDrag({
file: absPathOfFileToBeDragged,
icon: DROP_ICON_PATH
})
})
The above code is lightly modified for clarity from the tutorial on this page.

I'm looking for a little guidance and suggestions here. My attempts and theories will be at the bottom.
I have a NextJS project from which I want to export the top level component (essentially the entry file) so that I can use it as a preview in my dashboard.
The nextjs project is very simple. For the sake of simplicity, let's imagine that all it renders is a colored <h1>Hello world</h1>. Then in my dashboard, I want to render a cellphone with my NextJS component embedded and then from the dashboard change the color of the text, as a way to preview how it would look like. I hope this makes sense.
I'm lost at how I could export this component from NextJS and import it into my dashboard. The dashboard is rendered in Ruby on Rails. It would be simple enough to just import the repo from git and access the file directly form node_modules, but I'm looking for a solution that doesn't require installing npm on our Rails project.
Paths I have thought about:
1 - Install npm on Rails and just import the source code from NextJS repo and access the file and render with react (Simple, but we're looking for a non-npm solution)
2 - Bundle the component with webpack and load it directly into rails (does this even work?) - I exported the js and all it did was freeze everything :P Still trying this path for now
3 - Using an iframe and just accessing the page (then I can't pass any callbacks into the iframe to change the color directly from the dashboard)
4 - I cannot separate this component from NextJS to use as a library in both repos. The component we are exporting is the "ENTIRE" NextJS app jsx and it wouldn't make sense to separate in a different repo
Does anyone have a suggestion on how I could achieve this?
I think you could use an iframe with the nextjs app url. Then if you want to change the color, simply add the color in query parameter of the iframe and handle it on nextjs app.
Simple example
Rails view (erb)
<iframe src="#{#nextjs_url}?color=#{#color}" />
NextJS
# do something to get the query param of the page and and set to prop of the component
const YourComponent = ({color}) => {
return <h1 style={{color}}>Lorem</h1>;
}
While trying Hoang's solution, I decided to dive deeper into how to communicate with an iframe and the solution actually feels quite good.
You can set up listeners on either side and post messages in between the projects.
So in my dashboard:
function handleEvent(e) {
const data = JSON.parse(e.data)
if (data.type === "card_click") {
//if type is what we want from this event, handle it
}
}
// Setup a listener with a handler
// This will run every time a message is posted from my app
window.addEventListener("message", handleEvent, false)
const postMessage = (color) => {
const event = JSON.stringify({
type: "color_update",
color,
})
// Find the iframe and post a message to it
// This will be picked up by the listener on the other side
document.getElementById("my-iframe-id").contentWindow.postMessage(event, "*")
}
And on my app:
function handleEvent(e) {
const data = JSON.parse(e.data)
if (data.type === "color_update") {
// Do whatever is necessary with the data
}
}
// Setup listener
// This will fire with every message posted from my dashboard
window.addEventListener("message", handleEvent, false)
const handleCardClick = (cardIndex) => {
const event = JSON.stringify({
type: "card_click",
cardIndex,
})
// post message to parent, that will be picked up by listener
// on the other side
window.parent.postMessage(event, "*")
}
It feels pretty straight forward to communicate with an iframe with this solution.
I have a workflow that adds a button "Open Link" and a field on the record called "URL" that contains a hyperlink to an attachment in NetSuite. I want to add a workflow action script that opens this url in a different page. I have added the script and the workflow action to the workflow. My script:
function openURL() {
var url = nlapiGetFieldValue('custbody_url');
window.open(url);
}
I get this script error after clicking the button: "TypeError: Cannot find function open in object [object Object].
How can I change my script so it opens the URL in the field?
(This function works when I try it in the console)
Thanks!
Do you want it to work when the record is being viewed or edited? They have slightly different scripts. I'm going to assume you want the button to work when the record is being viewed, but I'll write it so it works even when the document is being edited as well.
The hard part about the way Netsuite has set it up is that it requires two scripts, a user event script, and a client script. The way #michoel suggests may work too... I've never inserted the script by text before personally though.
I'll try that sometime today perhaps.
Here's a user event you could use (haven't tested it myself though, so you should run it through a test before deploying it to everyone).
function userEvent_beforeLoad(type, form, request)
{
/*
Add the specified client script to the document that is being shown
It looks it up by id, so you'll want to make sure the id is correct
*/
form.setScript("customscript_my_client_script");
/*
Add a button to the page which calls the openURL() method from a client script
*/
form.addButton("custpage_open_url", "Open URL", "openURL()");
}
Use this as the Suitescript file for a User Event script. Set the Before Load function in the Script Page to userEvent_beforeLoad. Make sure to deploy it to the record you want it to run on.
Here's the client script to go with it.
function openURL()
{
/*
nlapiGetFieldValue() gets the url client side in a changeable field, which nlapiLookupField (which looks it up server side) can't do
if your url is hidden/unchanging or you only care about view mode, you can just get rid of the below and use nlapiLookupField() instead
*/
var url = nlapiGetFieldValue('custbody_url');
/*
nlapiGetFieldValue() doesn't work in view mode (it returns null), so we need to use nlapiLookupField() instead
if you only care about edit mode, you don't need to use nlapiLookupField so you can ignore this
*/
if(url == null)
{
var myType = nlapiGetRecordType();
var myId = nlapiGetRecordId();
url = nlapiLookupField(myType, myId,'custbody_url');
}
//opening up the url
window.open(url);
}
Add it as a Client Script, but don't make any deployments (the User Event Script will attach it to the form for you). Make sure this script has the id customscript_my_client_script (or whatever script id you used in the user event script in form.setScript()) or else this won't work.
Another thing to keep in mind is that each record can only have one script appended to it using form.setScript() (I think?) so you may want to title the user event script and client script something related to the form you are deploying it on. Using form.setScript is equivalent to setting the script value when you are in the Customize Form menu.
If you can get #michoel's answer working, that may end up being better because you're keeping the logic all in one script which (from my point of view) makes it easier to manage your Suitescripts.
The problem you are running into is that Workflow Action Scripts execute on the server side, so you are not able to perform client side actions like opening up a new tab. I would suggest using a User Event Script which can "inject" client code into the button onclick function.
function beforeLoad(type, form) {
var script = "window.open(nlapiGetFieldValue('custbody_url'))";
form.addButton('custpage_custom_button', 'Open URL', script);
}
I'm supper new here, either Javascript and JXA, so pardon me if I make some stupid questions. But I'm trying to figure out a way to get the string from the highlighted text using JXA - JavaScript for Automation, for Javascript can be recognized in Automator since Yosemite, I thought I can make something work with these:
window.getSelection in:
function getSelectedText() {
if (window.getSelection) {
txt = window.getSelection();
} else if (window.document.getSelection) {
txt =window.document.getSelection();
} else if (window.document.selection) {
txt = window.document.selection.createRange().text;
}
return txt;
}
This code is not mine, somebody posted this. But I've found out that I can't use window or document here in Automator to make change to Mac OS, so can someone show me how to convert this Javascript code into JXA which Automator can understand?
Thanks a lot!
In general, you can use the System Events app to copy and paste with any app.
'use strict';
//--- GET A REF TO CURRENT APP WITH STD ADDITONS ---
var app = Application.currentApplication()
app.includeStandardAdditions = true
var seApp = Application('System Events')
//--- Set the Clipboard so we can test for no selection ---
app.setTheClipboardTo("[NONE]")
//--- Activate the App to COPY the Selection ---
var safariApp = Application("Safari")
safariApp.activate()
delay(0.2) // adjust the delay as needed
//--- Issue the COPY Command ---
seApp.keystroke('c', { using: 'command down' }) // Press ⌘C
delay(0.2) // adjust the delay as needed
//--- Get the Text on the Clipboard ---
var clipStr = app.theClipboard()
console.log(clipStr)
//--- Display Alert if NO Selection was Made ---
if (clipStr === "[NONE]") {
var msgStr = "NO Selection was made"
console.log(msgStr)
app.activate()
app.displayAlert(msgStr)
}
For more info see:
Sending Keystrokes in JXA
JXA Resources
You need to mix JXA and Safari’s javaScript…
var Safari = Application("Safari") // get Safari
selection = Safari.doJavaScript("document.getSelection().toString()",{
in: Safari.windows[0].tabs[0] // assume frontmost window and tab
})
The script is in JXA, but the document.getSelection().toString() is Safari’s javaScript.
Of course you will need to enable apple events in Safari… http://osxdaily.com/2011/11/03/enable-the-develop-menu-in-safari/
If you want the selected text from another application, the code might be very different.
Don't do that, it's only applicable to JavaScript embedded inside a web browser. JXA is a standalone JS interpreter that has absolutely no understanding of web pages or DOM (and frankly doesn't have much clue about Mac application scripting either, btw).
Instead, use Automator to create an OS X Service as services can manipulate selected text in almost any OS X app; no application scripting required.
I use this code to intercept a dialog from a webview but I can not see the content or interact with it:
Element webview= querySelector("#webview");
Map<String,String> map=new Map();
map["src"]=urlWebView+user;
webview.attributes.addAll(map);
querySelector("#webview_cont").style.visibility="visible";
window.addEventListener("dialog",(Event e){ //Use window or webview returns the same result
e.preventDefault();
... //What should I do here ??
} );
Any solution?
Thanks

The problem definitely lies with your usage of Dart's Event class.
It simply does not support the extra properties that Chrome is adding to the event: e.dialog, e.messageText, e.messageType.
It does not seem like there is a ready solution for that, at least not in chrome.dart.
Sadly, I don't know Dart well enough to give you a solution. You need to somehow extend that event class, possibly dropping to JS level.
This library, even if abandoned, should give you ideas on how to do that (by catching the JS-level event and stuffing the extra properties in CustomEvent's detail property), though implementing DialogController (which is not JSON-serializable) would be a bit trickier, I guess.
Does anyone know what might have changed since v3.0.5 that would enable extensions to work? Or, maybe I'm missing a setting somewhere? I wrote this add-on that works fine with newer versions, but I can't get it to launch in older ones. Specifically, I can't even get this part to work (this is in my browser overlay.xul):
<html:script>
<![CDATA[
var Cc = Components.classes;
var Ci = Components.interfaces;
var obSvc = Cc["#mozilla.org/observer-service;1"].getService(Ci.nsIObserverService);
gBrowser.consoleService = Cc["#mozilla.org/consoleservice;1"].getService(Ci.nsIConsoleService);
gBrowser.log = function(msg){
this.consoleService.logStringMessage(msg);
}
gBrowser.newObj= new MyAddOn();
gBrowser.log("initializing...");
function regListener()
{
obSvc.addObserver(gBrowser.newObj, "http-on-modify-request", false);
}
function unregListener()
{
obSvc.removeObserver(gBrowser.newObj, "http-on-modify-request");
}
window.addEventListener("load", regListener, false);
window.addEventListener("unload", unregListener, false);
]]>
This should attach listeners to the new obj (defined by a linked .js) However, I'm not even getting the "initializing..." message in the console. Any ideas?
Don't use <html:script>, use <script> (assuming you have xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul" on your root <overlay> element).
Don't register an application-global listener (http-on-modify-request) from a window overlay. Doing so will make your code run one time in each window the user may have open. Use an XPCOM component instead - https://developer.mozilla.org/en/Setting_HTTP_request_headers
Don't pollute common objects (like gBrowser or the global object (with var Cc)) with your own properties. If everyone did that, no two extensions would work together. Put all your code properties on your own object with a unique name.
accessing gBrowser before the load event is probably what's causing your specific problem.
Set up your environment and check the Error Console to debug problems.
Don't waste time trying to support Firefox 3. It's not supported by Mozilla itself for over a year and shouldn't be used to access the web.
It looks like gBrowser.log is not defined, or at least is not a function, as the error console will probably tell you. I've never heard of it either. Maybe it was added in Fx 3.5?
