[−][src]Struct yew::services::keyboard::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).
Implementations
impl KeyboardService
[src]
pub fn register_key_press<T: AsRef<EventTarget>>(
element: &T,

) -> KeyListenerHandle
[src]
element: &T,
callback: Callback<KeyboardEvent>
) -> KeyListenerHandle
Registers a callback which listens to KeyPressEvents on a provided element.

pub fn register_key_down<T: AsRef<EventTarget>>(
element: &T,
callback: Callback<KeyboardEvent>
) -> KeyListenerHandle
[src]
element: &T,
callback: Callback<KeyboardEvent>
) -> KeyListenerHandle
Registers a callback which listens to KeyDownEvents on a provided element.
