cliptext | Built with Electron.js

The name of the listview item is not the column name. It is there in case you want to differentiate what you present to the user (text) and the actual value you will work it behind the scene.

To get the column name, you need to make your own solution. Here is something that would work.

To be declared somewhere before the Add_SelectedIndexChangedMethod so it doesn't get called every time for nothing.

I'm guessing you are testing it in Firefox, in that case:

Firefox only supports reading the clipboard in browser extensions, using the "clipboardRead" extension permission.

As of Android 10 and later, your app needs to have input focus to read clipboard successfully. Otherwise getPrimaryClip() returns null.

onCreate() is too early for your activity to have input focus. You can override onWindowFocusChanged() to attempt to read the clipboard as soon as there is focus.

Looks like fabric.js relies heavily on caching when Image object has a clipPath.

During the render call, it checks this.needsItsOwnCache() which returns true because this.clipPath is present. Then it calls this.renderCache(), which only updates the cached canvas if this.isCacheDirty() returns true.

For it to return true, you can utilize the object's statefullCache and cacheProperties setting a custom videoTime property with a value of video element's currentTime. Then you just make sure to update videoTime on each animation frame.
