# Modules.Map.Polyline
Represents a bounded area on the map.
# Overview
The Polyline
object gives you low-level control over polylines that can be added to a
Modules.Map.View. A polyline must have its points
property set to appear on a map.
Use the Modules.Map.createPolyline method to create a polyline.
# Example
var polyline = Map.createPolyline({
points: [{
latitude: -33.891614,
longitude: 151.276417
},
[-33.87365, 151.20689]
],
strokeWidth: 3,
strokeColor: '#f00',
zIndex: 1
});
mapView.addPolyline(polyline);
# Properties
# apiName READONLY
The name of the API that this proxy corresponds to.
The value of this property is the fully qualified name of the API. For example, Titanium.UI.Button
returns Ti.UI.Button
.
# bubbleParent
Indicates if the proxy will bubble an event to its parent.
Some proxies (most commonly views) have a relationship to other proxies, often established by the add() method. For example, for a button added to a window, a click event on the button would bubble up to the window. Other common parents are table sections to their rows, table views to their sections, and scrollable views to their views. Set this property to false to disable the bubbling to the proxy's parent.
Default: true
# jointType CREATION ONLY
Defines the shape of corner points.
Defines the shape of corner points. Can be one of the following shapes: POLYLINE_JOINT_DEFAULT, POLYLINE_JOINT_ROUND or POLYLINE_JOINT_BEVEL
Default: Modules.Map.POLYLINE_JOINT_DEFAULT
# lifecycleContainer
The Window or TabGroup whose Activity lifecycle should be triggered on the proxy.
If this property is set to a Window or TabGroup, then the corresponding Activity lifecycle event callbacks will also be called on the proxy. Proxies that require the activity lifecycle will need this property set to the appropriate containing Window or TabGroup.
# pattern
Pattern used to draw the polylines.
As per default polylines are drawn with a solid line. You can specify to draw them with a dashed line using POLYLINE_PATTERN_DASHED or with a dotted line using POLYLINE_PATTERN_DOTTED.
You can also specify the dimensions to use when you create a dashed or dotted polyline.
For a dashed polyline, you can do something like this:
polyline.setPattern({
type: TiMap.POLYLINE_PATTERN_DASHED,
gapLength: 25,
dashLength: 50
});
or for a dotted polyline, you can do:
polyline.setPattern({
type: TiMap.POLYLINE_PATTERN_DOTTED,
gapLength: 25
});
# points CREATION ONLY
Array of map points making up the polyline. Can also be an array of longitude (index 0), latitude (index 1) touples. On Android platform you can use an encoded polyline as string.
# strokeColor
Color to use for the the polyline, as a color name or hex triplet.
For information about color values, see the "Colors" section of Titanium.UI.
Default: black
# strokeWidth
Line width in pixels to use when drawing the polyline.
Default: 10
# touchEnabled
Determines whether view should receive touch events.
Default: true
# zIndex CREATION ONLY
The order (depth) in which to display the polylines.
For iOS, the polylines are drawn in the order in which they are added.
# Methods
# addEventListener
Adds the specified callback as an event listener for the named event.
Parameters
Name | Type | Description |
---|---|---|
name | String | Name of the event. |
callback | Callback<Titanium.Event> | Callback function to invoke when the event is fired. |
Returns
- Type
- void
# applyProperties
Applies the properties to the proxy.
Properties are supplied as a dictionary. Each key-value pair in the object is applied to the proxy such that myproxy[key] = value.
Parameters
Name | Type | Description |
---|---|---|
props | Dictionary | A dictionary of properties to apply. |
Returns
- Type
- void
# fireEvent
Fires a synthesized event to any registered listeners.
Parameters
Name | Type | Description |
---|---|---|
name | String | Name of the event. |
event | Dictionary | A dictionary of keys and values to add to the Titanium.Event object sent to the listeners. |
Returns
- Type
- void
# removeEventListener
Removes the specified callback as an event listener for the named event.
Multiple listeners can be registered for the same event, so the
callback
parameter is used to determine which listener to remove.
When adding a listener, you must save a reference to the callback function in order to remove the listener later:
var listener = function() { Ti.API.info("Event listener called."); }
window.addEventListener('click', listener);
To remove the listener, pass in a reference to the callback function:
window.removeEventListener('click', listener);
Parameters
Name | Type | Description |
---|---|---|
name | String | Name of the event. |
callback | Callback<Titanium.Event> | Callback function to remove. Must be the same function passed to |
Returns
- Type
- void
