Enum PointerKind 

#[non_exhaustive]
pub enum PointerKind {
    Down(PointerButton),

    Enter,
    Leave,

What a pointer did.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Down(PointerButton)

A button was pressed.

Up(PointerButton)

A button was released.

Move

The pointer moved.

Scroll(ScrollDelta)

A wheel or touchpad scrolled.

Enter

The pointer came over the widget. Widgets receive it from the Ui, which ignores it as input.

Leave

The pointer left the widget. Widgets receive it from the Ui, which ignores it as input.

Cancel

The press the widget was holding the pointer for was cancelled (the window lost focus): forget any drag. Widgets receive it from Ui::cancel_pointer.
