Namespace
The namespace is really just an object where further objects and their methods and properties are attached bundling up all the functionality using a unique name.
Interface
The Interface is a contract by which the implementing class adheres. It describes a desired behavior and enforces adherence for any class that implements the interface.
Class
Classes define types of objects that will be used by the application.
Method
A function associated with a class or object.
Field
A variable associated with a class or object.
Inherited Method
A function inherited from the parent class. The present documentation scheme differentiates between a direct or indirect inheritance relationship.
Inherited Field
A variable inherited from the parent class. The present documentation scheme differentiates between a direct or indirect inheritance relationship.
Event
Events are actions that occur because of user interaction. They are normally used in combination with functions, and the function will not be executed before the event occurs.
Interface nokia.maps.dom.TouchEventTarget
Interface Summary
This class is a virtual interface that exists only for documentation purposes. Each class implementing this interface delcares that it can act as the target for certain events. Each event in this interface (and therefore also within the classes implementing the interface) represents an event of a specific type.
The following example shows event handling for events of the type "click":
// Note that "obj" can be either a DOM node or any other JavaScript object.
var obj = nokia.maps.dom.EventTarget( {} );
obj.addListener("click", function (evt) {
console.log("This is the '"+evt.type+"' event!");
});
obj.dispatch( new nokia.maps.dom.Event({
type: "click"
});
The example creates an instant of nokia.maps.dom.EventTarget, adds a listener
for "click" events to it, and dispatches a "click" event to all registered listeners (in
this case one) - the listeners receive the object that represents the target of the event.
For more information about dispatching events, please refer to the documentation of the nokia.maps.dom.EventTarget.
Events
dbltap(evt)
This event is fired after a two
tap events have been fired in a certain amount of time.
Parameters:
| {nokia.maps.dom.TouchEvent} | evt | An object representing the event |
gesturechange(evt)
This high-level event is fired whenever either of the two finger making a gesture is moved, changing the
properties of the gesture.
Parameters:
| {nokia.maps.dom.TouchEvent} | evt | An object representing the event |
gestureend(evt)
This high-level event is fired as soon as the gesture ends, for example because one of
the two fingers touching the touch screen are lifted.
Parameters:
| {nokia.maps.dom.TouchEvent} | evt | An object representing the event |
gesturestart(evt)
This high-level event is fired when two or more fingers touch the touch screen and are used to make
a "gesture".
Parameters:
| {nokia.maps.dom.TouchEvent} | evt | An object representing the event |
longpress(evt)
This event is fired after a finger has been pressed against the screen for a certain amount of time
without starting a drag or gesture.
Parameters:
| {nokia.maps.dom.TouchEvent} | evt | An object representing the event |
tap(evt)
This event is fired after a
touchstart and touchend has occurred
at the same target and only if neither of the touchstart nor the touchend
event has been canceled and no gesture was started in between.
Parameters:
| {nokia.maps.dom.TouchEvent} | evt | An object representing the event |
touchend(evt)
This event is fired when a finger is lifted from a touch screen.
Parameters:
| {nokia.maps.dom.TouchEvent} | evt | An object representing the event |
touchmove(evt)
This event is fired when a finger touches and moves on a touch screen. This event
is different from a
mousemove event, because the user can touch the
screen with more than one finger at the same time.
Parameters:
| {nokia.maps.dom.TouchEvent} | evt | An object representing the event |
touchstart(evt)
This event is fired when a finger is touches a touch screen.
Parameters:
| {nokia.maps.dom.TouchEvent} | evt | An object representing the event |
