Struct TabMotion

Source 
pub struct TabMotion(/* private fields */);
Expand description

Animation state of a tab strip, kept by the app across frames.

Hand the same value to TabStrip::motion on every view and return Self::is_animating from App::is_animating. A tab that opens grows from nothing and the others narrow to make room; a tab that closes leaves a gap that shrinks away while the others keep their width for a moment, so the close button of the tab that slides in lands under the pointer. Clones share the state.

A reorderable strip or overview is dragged through the app: forward App::on_drag_move to Self::drag_move and answer App::on_drop with what Self::drag_end reports. A strip and its overview, never shown at once, may share one.

Implementations§

Source§

impl TabMotion

Source

pub fn new() -> Self

Source

pub fn is_animating(&self) -> bool

A tab is moving or being dragged, or the others are holding their width after a close.

Source

pub fn drag_move(&self, x: f32, y: f32) -> bool

Follow the pointer, in physical pixels; false when the drag did not start on one of the tabs.

Source

pub fn drag_end(&self) -> Option<(usize, usize)>

End the drag: the index the tab had and the one it has now, when it moved.
