One approach I tried is using a multi-part response. But the browser doesn't fire a 'load' event in the iframe. I return a ' Content-Disposition: attachment' header with the file, which causes the browser to show the 'Save' dialog. I listen for a 'load' event on the iframe, hoping that it will fire when the download is complete.

This is, so I don't replace the entire browser window with the result. I'm requesting a hidden form, which POSTs to the server, and targets a hidden iframe for its results. The problem is, I can't figure out how to detect when the browser has received the file so that I can hide the indicator. It takes a long time to generate, so I'd like to show a 'waiting' indicator. Generated when a window within this application requires credentials from the user.I have a page that allows the user to download a dynamically-generated file. Generated when an alert is fired and suppressed due to the customWindowAlert flag being true. const app = await () Īpp.addListener('closed', function(event), // see the monitor-info-changed payload in the system module for details addListener(event, listener)Īdds a listener to the end of the listeners array for the specified event. It is possible to use ES6 Arrow Functions as listeners, however, when doing so, the this keyword will no longer reference the EventEmitter instance. It is important to keep in mind that when an ordinary listener function is called, the standard this keyword is intentionally set to reference the EventEmitter instance to which the listener is attached. If the execution context of the window is destroyed by page navigation or reload, any events that have been setup in that context will be destroyed. Any values returned by the called listeners are ignored and will be discarded. When the EventEmitter receives an event from the browser process and emits on the renderer, all of the functions attached to that specific event are called synchronously. The below methods are asynchronous as they must cross process boundaries and setup the listener in the browser process. When an instance of fin.Application is created, it inherits an EventEmitter with the below methods so that it is possible to listen to OpenFin events.
