Required Methods§

Source

fn get_offset(&self) -> Option<(f64, f64)>

Source

fn get_start_point(&self) -> Option<(f64, f64)>

Source

fn connect_drag_begin<F: Fn(&Self, f64, f64) + 'static>( &self, f: F, ) -> SignalHandlerId

Source

fn connect_drag_end<F: Fn(&Self, f64, f64) + 'static>( &self, f: F, ) -> SignalHandlerId

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
