## What's new * Extends @varphone's excellent `raw_input_hook` idea from #4008 to `web/app_runner`. ## Details Debugging this locally after my app's `raw_input_hook` wasn't being called, I realized it's not in the code path of eframe's web runner, only the native integration. Below is a toy example running on the web. https://github.com/emilk/egui/assets/8173478/d470b7e6-d393-4ead-9745-3aafc72ae6bc

…ltering of raw input events (emilk#4008) # What's New * eframe: Added `App::raw_input_hook` allows for the manipulation or filtering of raw input events A filter applied to raw input before [`Self::update`] This allows for the manipulation or filtering of input events before they are processed by egui. This can be used to exclude specific keyboard shortcuts, mouse events, etc. Additionally, it can be used to add custom keyboard or mouse events generated by a virtual keyboard. * examples: Added an example to demonstrates how to implement a custom virtual keyboard.
