I have a Electron App which, on the press of a button, opens a new Window. Said Window has another button with the id of "closeBtn". Now i try to handle it in the js associated to said element with the following code
const electron = require("electron")
const path = require("path")
const remote = electron.remote
const closeBtn = document.getElementById("closeBtn")
closeBtn.addEventListener("click", function(e) {
var window = remote.getCurrentWindow();
window.close();
})
But somehow that doesn´t work, and the new window is not closing on the Button Press. What am i doing wrong?
Fixed it by adding webPreferences {nodeIntegration: true} to the values of my newly generated Window.
I am new to UI coding and started using react-admin for putting some simple pages. Everything went well and we are able to host pages correctly. But we have noticed random issues where the background image is filling up the entire screen or sometimes the whole page gets reduced to the hamburger menu. I have disabled the registerServiceWorker to stop having my pages in cache. Not sure if this is causing the weird UI behavior.
I don't know why you get those issues, the description is way too generic and it seems you don't have any idea what the problem can be, probably due to being new to the area. Either way the kind of problem you appear to have is probably related to CSS which is a way give style to your page. But React Admin doesn't use CSS directly, you can use it that way, but for more dynamic way to style the page the Material-ui library uses a thing called JSS to apply the styles.
There are many libraries that are being used together in order to produce React Admin, you should have an understanding of the most important ones in order to do something fancy. My advice to you since you are new, and you pretend to use React Admin, first use what React Admin offers and when you feel comfortable using that components and have a general grasp how the framework works, after that start implementing your own components that don't have a direct relation to React Admin but use some of the same libraries of React Admin.
Also check if you are creating a React Admin app using the <Admin> component or are embedding React Admin in another app since the second is more probable to produce bugs.
After some debugging, I think i figured out the cause of this issue. I had a custom button to duplicate a row (basically post a create and route to edit page on the new id). For some reason, the rendering of that button seems to have caused this issue inconsistently. The actual button works fine but causes this inconsistent behavior. Below is the code for that button. Is there any issue with the below?:
export default class DuplicateButton extends Component {
constructor(props) {
super(props);
this.handleClick = this.handleClick.bind(this);
this.state = ({ redirect: false });
var redirectPath = '';
}
handleClick = (props) => {
var
{
push, record, resourceName
} = this.props;
let tempRecord = record;
var result = '';
console.log(this.props);
var p = restDataProvider(CREATE, this.props.resource + "/" + tempRecord.id, { data: tempRecord }).then(resp => {
result = resp.data;
let routePath = '/' + this.props.resource + '/' + result.id;
console.log(routePath);
this.redirectPath = routePath;
this.setState({ redirect: true });
return result;
});
}
render() {
if (this.state.redirect) {
console.log('Redirect to Edit page');
return <Redirect push to={this.redirectPath} />;
}
return <Button variant="flat" color="primary" label="Duplicate Entry" onClick={this.handleClick}><DuplicateIcon /></Button>;
}
}
I have an extension, functional on Chrome, that monitors the active Tab for URL changes.
Specifically, I need to detect when the URL changes, but there is no new page load or navigation. Some sites do this (e.g. when you click to view another video on YouTube).
On Chrome, I accomplished this with:
chrome.tabs.onUpdated.addListener(function(tabId, changeInfo, tab) {
if (changeInfo && changeInfo.status == "complete") {
//do stuff here
}
});
How do I detect such changes in a Firefox add-on?
I've been told to use: Listening to events on all tabs, but I couldn't put it together. One of the problems was that gBrowser was not defined in the extension.
What am I doing wrong?
Is there a simpler way?
Use ProgressListener to be notified about location changes.
To install a listener, convert SDK tab to its raw (old) representation using viewFor.
Backward conversion is possible with modelFor and getTabForContentWindow.
const tabs = require("sdk/tabs");
const {viewFor} = require('sdk/view/core');
const {modelFor} = require('sdk/model/core');
const {getBrowserForTab, getTabForContentWindow} = require("sdk/tabs/utils");
const {Ci, Cu} = require("chrome");
Cu.import("resource://gre/modules/XPCOMUtils.jsm", this);
var progressListener = {
QueryInterface: XPCOMUtils.generateQI([Ci.nsIWebProgressListener, Ci.nsISupportsWeakReference]),
onLocationChange: function(aProgress, aRequest, aURI) {
var highLevel= modelFor(getTabForContentWindow(aProgress.DOMWindow));
console.log("onLocationChange ", highLevel.url);
}
};
tabs.on('open', function(newTab) {
var lowLevel = viewFor(newTab);
var browser = getBrowserForTab(lowLevel);
browser.addProgressListener(progressListener);
});
Don't forget to remove listeners on extension unload. Tab listeners are removed automagically, but ProgressListeners won't be.

Converting to chrome windows
If you're using the add-on SDK, you're looking at the wrong docs. Here are the tab docs.
As stated there, you create a listener like so:
var tabs = require("sdk/tabs");
// Listen for tab openings.
tabs.on('open', function onOpen(tab) {
myOpenTabs.push(tab);
});
// Listen for tab content loads.
tabs.on('ready', function(tab) {
console.log('tab is loaded', tab.title, tab.url);
});
All the docs you look at should be a subset of developer.mozilla.org/en-US/Add-ons/SDK.
I find that the activate and pageshow events, between the two of them, cover all changes in URL that I can conjure up between switching tabs, opening pages in a new tab, closing tabs, refreshing pages, and typing in new URL's.
var updateURL = function (tab) {
var oldURL = url;
var url = tab.url;
console.log(url);
};
tabs.on("activate", updateURL);
tabs.on("pageshow", updateURL);
I have done a firefox addon using the Addon Builder. This addon display a panel containing a web page.
The problem I have is that I would like to keep this panel displayed and probably had a close button to hide it. Actually the panel disappear when we click out of the panel.
This is the code I use to make my panel:
var HauteurPopup = 400;
var LargeurPopup = 650;
function getPanel(contentURL){
var popupPanel = require("panel").Panel({
width:LargeurPopup,
height:HauteurPopup,
contentURL: contentURL
});
return popupPanel;
}
var btn = require("toolbarbutton").ToolbarButton({
id: 'propelink-button',
label: 'Propulesez ce lien!',
image: 'https://www.users.prplk.com/img/mini-logo-propel-bar.jpg',
onCommand: function() {
if (typeof(tabs.activeTab._worker) == 'undefined') {
let worker = tabs.activeTab.attach({
contentScript: btnContentScript
});
tabs.activeTab._worker = worker;
}
tabs.activeTab._worker.port.emit("btnContentScript");
var panelPopup = myPanel.getPanel("http://example.com");
panelPopup.show();
}
});
Someone know how to keep this panel displayed and close it adding a button?
Thanks in advance
In xul based extensions there is an option in the creation of the panel to accomplish that (panel.noautohide). In firefox-addon-sdk it seems that it doesn't exist. See 595040 – Add a "isPersistent" attribute for panels
Although it is mentioned that you can do a workaround by editing panel.js, but i never tried to do that, but you may want to give it a try.
I am developing an iOS app in Appcelerator and I want to switch between windows with the use of a swipe event listener. How can I do this? The below code does not work. The current window that I "start" from contains a table.
var window = Ti.UI.currentWindow;
window.addEventListener('swipe', function() {
// Create the new window
var win = Titanium.UI.createWindow({
title: 'Contacts',
url:'contacts_simple.js'
});
// Animate the page turn
Titanium.UI.currentTab.open(win, {animated:false});
});
I think the problem is with the Ti.UI.currentWindow. Depending on the context you're working in it may not be valid.
Google 'appcelerator currentWindow', but here's a related link:
http://developer.appcelerator.com/question/5391/currentwindow
This will not be optimal and dynamic, but to start with, try referencing the window implicitly. Meaning if you did something like
var window_x = Ti.UI.createWindow({});
try
window_x.addEventListener('swipe', function() {...});
