The Electron BrowserWindow event triggered when the window is closed

Is it possible to retrieve values when closing a BrowserWindow in electron?

Ideally, I am looking for a method to access the variables from the close event:

win.on('closed', function(variables can be accessed) {
        console.log(variables + ' ' + can + ' ' + be);
        win = null;
    });

Answer №1

Regrettably, there is no direct way to retrieve values within the close event. Nevertheless, you can execute a function before the window closes by utilizing window.onbeforeunload.

Within this function, you can extract the necessary information or data from your BrowserWindow instance and transmit a synchronous IPC message to your main process to acquire the required variables.
By sending it synchronously and then returning undefined, you can obtain the required variables while still allowing the BrowserWindow to close, triggering your desired close event.

According to their documentation:

Typically, the beforeunload handler is used to determine if the window should be closed, which is also triggered when the window is reloaded. In Electron, returning any value other than undefined would prevent the window from closing.

Refer to the close event for additional details.
