OpenWindow | unified API to talk to native windowing libraries | Video Utils library

I try to verify that window.open() is called within a then block. Here is a minimal example.

I started creating a shooter game with ursina, and I tried to get exe from this using pyinstaller. after I got the exe, when I run the app, it show me an error(o I have coded a new game with ursina, but I got this:

For my electron app, I would like to open another Svelte-window (or load different windows/components depending on the startup variables).

So let's say I used this tutorial to set up a basic structure, with my App.svelte looking like this:

I'm trying to hide certain ReorderableList items based on the state of a boolean toggle. What I'm currently getting is a blank item instead of no item at all. No items hidden:

Hiding Item 1 (toggle clicked):

Here's the code:

Items.cs

In the main window of my program, I have a button that, if clicked, creates a new, additional window. When this new window finishes loading, I want to send a message to ipcRenderer; however, I have not been able so far to make ipcRenderer able to receive the message, even though the window is created successfully.

Here's a snippet of the code in main.js:

I need to implement the tabulate function (using MenuItem TabulateFunction), which is located in a file with the extension .class in the form of byte-code. Since the function can have one of the three classes that implement my interface, then, according to the task, you need to implement a separate class that will be responsible for reading the byte-code from the file and create an object based on this byte-code.

I made a class ClassLoaderForFunctions and use return defineClass in it And here is the problem. When I select Tabulate Function in my menu, it calls the method from ClassLoaderForFunctions which implements the above for the function from the file.

And when it comes to return defineClass, I get an error: Exception in thread JavaFX Application Thread" java.lang.ClassFormatError: Incompatible magic value 11 in class file tlog/class

In the Main class I call the controller and write the byte code of the tlog object in a file with the extension .class

*I deleted the import lines for the sake of Stack Trace

What could be the problem?

ClassLoaderForFunctions:

I have implemented push notifications for my PWA and my service worker (SW) is currently handling clicks on a notifications like this:

1. If the app is running it will put it in the foreground and send it some data using the Client.postMessage API
2. If the app is not running it will launch it via Client.openWindow using URL parameters that contain some minimal information about the push notification

Point 1 works just as I want. But for 2, I would like to be able to send to my app the same data as for 1, and I cannot add it to the URL (the payload is too large). The issue is that I can only use Client.postMessage when my app is ready to receive such messages...

What is the simplest way to do that?

Note: my use case is a chat app for which a push notification is displayed when a message is received and a click on the notification triggers the app and shows the corresponding chat and message. I want to pass the content of the message itself (which is in the push notification received by the service worker) to the app so it can show directly, instead of having to pull it from the backend.

Im currently practicing how to use WPF on C#, ive gotten the basics of it but im facing an issue, ive set up my code to open a new window when a button is clicked however the view does not update to how window 2 is supposed to look it just shiws the same view as window1 but the changing from window to window is working just the content is not changing.
