DropAction

Required methods

pub fn connect_can_drop<F>(&self, f: F) -> SignalHandlerId where
    F: 'static + Fn(&Self, &Actor, f32, f32) -> bool, [src]

The ::can-drop signal is emitted when the dragged actor is dropped on actor. The return value of the ::can-drop signal will determine whether or not the DropAction::drop signal is going to be emitted on action.

The default implementation of DropAction returns true for this signal.

actor

the Actor attached to the action

event_x

the X coordinate (in stage space) of the drop event

event_y

the Y coordinate (in stage space) of the drop event

Returns

true if the drop is accepted, and false otherwise

pub fn connect_drop<F>(&self, f: F) -> SignalHandlerId where
    F: 'static + Fn(&Self, &Actor, f32, f32), [src]

The ::drop signal is emitted when the dragged actor is dropped on actor. This signal is only emitted if at least an handler of DropAction::can-drop returns true.

actor

the Actor attached to the action

event_x

the X coordinate (in stage space) of the drop event

event_y

the Y coordinate (in stage space) of the drop event

pub fn connect_drop_cancel<F>(&self, f: F) -> SignalHandlerId where
    F: 'static + Fn(&Self, &Actor, f32, f32), [src]

The ::drop-cancel signal is emitted when the drop is refused by an emission of the DropAction::can-drop signal.

After the ::drop-cancel signal is fired the active drag is terminated.

actor

the Actor attached to the action

event_x

the X coordinate (in stage space) of the drop event

event_y

the Y coordinate (in stage space) of the drop event

pub fn connect_over_in<F>(&self, f: F) -> SignalHandlerId where
    F: 'static + Fn(&Self, &Actor), [src]

The ::over-in signal is emitted when the dragged actor crosses into actor.

actor

the Actor attached to the action

pub fn connect_over_out<F>(&self, f: F) -> SignalHandlerId where
    F: 'static + Fn(&Self, &Actor), [src]

The ::over-out signal is emitted when the dragged actor crosses outside actor.

actor

the Actor attached to the action
