Required methods

pub fn get_animating(&self) -> bool

get_animating: @spinner: A #Surface widget

Determines whether the spinner is animating.

Returns: %true if the spinner is animating, %false otherwise

pub fn set_animating(&self, animating: bool)

set_animating: @spinner: A #Surface widget @animating: %true to enable animation, %false to disable

Sets whether the spinner is animating. A spinner can be stopped if the task it represents has finished, or to save energy.

pub fn connect_draw<F>(&self, f: F) -> SignalHandlerId where
    F: 'static + Fn(&Self, &dyn CanvasContext<Pattern>, i32, i32) -> bool, 

The Canvas::draw signal is emitted each time a canvas is invalidated.

It is safe to connect multiple handlers to this signal: each handler invocation will be automatically protected by cairo_save and cairo_restore pairs.

cr

the Cairo context used to draw

width

the width of the canvas

height

the height of the canvas

Returns

true if the signal emission should stop, and false otherwise

pub fn connect_looped<F>(&self, f: F) -> SignalHandlerId where
    F: 'static + Fn(&Self), 

pub fn connect_property_animating_notify<F>(&self, f: F) -> SignalHandlerId where
    F: 'static + Fn(&Self),
