Struct KeyboardService

pub struct KeyboardService {}

Service for registering callbacks on elements to get keystrokes from the user.

Note

Elements which natively support keyboard input (such as <input/> or <textarea/>) can use the onkeypress or oninput attributes from within the html macro. You should use those events instead of locating the element and registering an event listener using this service.

This service is for adding key event listeners to elements which don’t support these attributes, (for example the document and <canvas> elements).
