[−][src]Struct dragula::Drake
Interface provided by Dragula to interact with active drag-and-drop system
Example:
use dragula::*; let doc = web_sys::window().unwrap().document().unwrap(); let element_1 = doc.get_element_by_id("drag-container-1").unwrap(); let element_2 = doc.get_element_by_id("drag-container-2").unwrap(); let mut drake = dragula(&[element_1]); drake.add_container(element_2);
Implementations
impl Drake
[src]
impl Drake
[src]
pub fn end(&self)
[src]
Gracefully end the drag event as if using the last position marked by
the preview shadow as the drop target. The proper cancel
or drop
event will be fired, depending on whether the item was dropped back
where it was originally lifted from (which is essentially a no-op
that's treated as a cancel
event).
impl Drake
[src]
pub fn remove(&self)
[src]
If an element managed by Drake
is currently being dragged, this method
will gracefully remove it from the DOM.
impl Drake
[src]
pub fn destroy(&self)
[src]
Removes all drag and drop events used by dragula
to manage drag and
drop between the containers
. If destroy
is called while an element
is being dragged, the drag will be effectively cancelled.
impl Drake
[src]
pub fn cancel(&self)
[src]
If an element managed by Drake
is currently being dragged, this method
will gracefully cancel the drag action.
Note that a "cancellation" will result in a cancel
event only in
the following scenarios.
revert_on_spill
istrue
- Drop target (as previewed by the feedback shadow) is the source container and the item is dropped in the same position where it was originally dragged from
impl Drake
[src]
pub fn cancel_with_revert(&self, revert: bool)
[src]
If an element managed by Drake
is currently being dragged, this method
will gracefully cancel the drag action. If true
is passed to this
function, it will effectively produce the same result as if
revert_on_spill
is true.
revert_on_spill
istrue
- Drop target (as previewed by the feedback shadow) is the source container and the item is dropped in the same position where it was originally dragged from
impl Drake
[src]
pub fn containers(&self) -> Vec<JsValue>
[src]
Gets the active containers currently allowing dragging
Requires that feature js-sys
be turned on (it is on by default)
pub fn set_containers<T>(&mut self, objs: &[T]) where
T: JsCast + Clone,
[src]
T: JsCast + Clone,
Sets the list of active containers for dragging. This overrides the list that is currently there.
pub fn add_container<T>(&mut self, obj: T) where
T: JsCast,
[src]
T: JsCast,
Adds to the list of active containers for dragging
Requires that feature js-sys
be turned on (it is on by default)
pub fn start<T>(&mut self, item: &T) where
T: JsCast,
[src]
T: JsCast,
Enter drag mode without a shadow. This function is most useful when
providing complementary keyboard shortcuts to an existing drag and drop
solution. Even though a shadow won't be created at first, the user will
get one as soon as they click on item
and start dragging it around.
Note that if they click and drag something else, end
will be called
before picking up the new item.
pub fn can_move<T>(&self, item: &T) -> bool where
T: JsCast,
[src]
T: JsCast,
Returns whether the Drake
instance can accept drags for a DOM element
item
. This function returns true
when all the conditions outlined
below are met, and false
otherwise.

pub fn on_drag<F: 'static>(&mut self, listener: F) where
F: FnMut(JsValue, JsValue),
[src]
F: FnMut(JsValue, JsValue),
Sets callback for drag
event.
Callback will be passed arguments (el, source)
The drag
event implies that
el
was lifted from source
.
pub fn on_dragend<F: 'static>(&mut self, listener: F) where
F: FnMut(JsValue),
[src]
F: FnMut(JsValue),
Sets callback for dragend
event.
Callback will be passed argument (el)
The dragend
event implies that
dragging event for el
ended with either cancel
, remove
, or drop
.
pub fn on_drop<F: 'static>(&mut self, listener: F) where
F: FnMut(JsValue, JsValue, JsValue, JsValue),
[src]
F: FnMut(JsValue, JsValue, JsValue, JsValue),
Sets callback for drop
event.
Callback will be passed arguments (el, target, source, sibling)
The drop
event implies that
el
was dropped into target
before a sibling
element, and
originally came from source
.
pub fn on_cancel<F: 'static>(&mut self, listener: F) where
F: FnMut(JsValue, JsValue, JsValue),
[src]
F: FnMut(JsValue, JsValue, JsValue),
Sets callback for cancel
event.
Callback will be passed argument (el, container, source)
The cancel
event implies that
el
was being dragged but it got nowhere and went back into
container
, its last stable parent; el
originally came from source
.
pub fn on_remove<F: 'static>(&mut self, listener: F) where
F: FnMut(JsValue, JsValue, JsValue),
[src]
F: FnMut(JsValue, JsValue, JsValue),
Sets callback for remove
event.
Callback will be passed argument (el, container, source)
The remove
event implies that
el
was being dragged but it got nowhere and it was removed from the
DOM. Its last stable parent was container
, and originally came from
source
.
pub fn on_shadow<F: 'static>(&mut self, listener: F) where
F: FnMut(JsValue, JsValue, JsValue),
[src]
F: FnMut(JsValue, JsValue, JsValue),
Sets callback for shadow
event.
Callback will be passed argument (el, container, source)
The shadow
event implies that
el
, the visual aid shadow, was moved into container
. May trigger
many times as the position of el
changes, even within the same
container
; el
originally came from source
.
pub fn on_over<F: 'static>(&mut self, listener: F) where
F: FnMut(JsValue, JsValue, JsValue),
[src]
F: FnMut(JsValue, JsValue, JsValue),
Sets callback for over
event.
Callback will be passed argument (el, container, source)
The over
event implies that
el
is over container
, and originally came from source
.
pub fn on_out<F: 'static>(&mut self, listener: F) where
F: FnMut(JsValue, JsValue, JsValue),
[src]
F: FnMut(JsValue, JsValue, JsValue),
Sets callback for out
event.
Callback will be passed argument (el, container, source)
The out
event implies that
el
was dragged out of container
or dropped, and originally came from
source
.
pub fn on_cloned<F: 'static>(&mut self, listener: F) where
F: FnMut(JsValue, JsValue, JsValue),
[src]
F: FnMut(JsValue, JsValue, JsValue),
Sets callback for cloned
event.
Callback will be passed argument (clone, original, type)
The cloned
event implies that
DOM element original
was cloned as clone
, of type
('mirror'
or
'copy'
). Fired for mirror images and when copy: true
.
Methods from Deref<Target = JsValue>

pub const UNDEFINED: JsValue
[src]
pub const TRUE: JsValue
[src]
pub const FALSE: JsValue
[src]
pub fn as_f64(&self) -> Option<f64>
[src]
Returns the f64
value of this JS value if it's an instance of a
number.
If this JS value is not an instance of a number then this returns
None
.
pub fn is_string(&self) -> bool
[src]
Tests whether this JS value is a JS string.
pub fn as_string(&self) -> Option<String>
[src]
If this JS value is a string value, this function copies the JS string
value into wasm linear memory, encoded as UTF-8, and returns it as a
Rust String
.
To avoid the copying and re-encoding, consider the
JsString::try_from()
function from js-sys
instead.
If this JS value is not an instance of a string or if it's not valid
utf-8 then this returns None
.
UTF-16 vs UTF-8
JavaScript strings in general are encoded as UTF-16, but Rust strings
are encoded as UTF-8. This can cause the Rust string to look a bit
different than the JS string sometimes. For more details see the
documentation about the str
type which contains a few
caveats about the encodings.
pub fn as_bool(&self) -> Option<bool>
[src]
Returns the bool
value of this JS value if it's an instance of a
boolean.
If this JS value is not an instance of a boolean then this returns
None
.
pub fn is_null(&self) -> bool
[src]
Tests whether this JS value is null
pub fn is_undefined(&self) -> bool
[src]
Tests whether this JS value is undefined
pub fn is_symbol(&self) -> bool
[src]
Tests whether the type of this JS value is symbol
pub fn is_object(&self) -> bool
[src]
Tests whether typeof self == "object" && self !== null
.
pub fn is_function(&self) -> bool
[src]
Tests whether the type of this JS value is function
.
pub fn is_truthy(&self) -> bool
[src]
Tests whether the value is "truthy".
pub fn is_falsy(&self) -> bool
[src]
Tests whether the value is "falsy".
