Controls overview

After this long introduction to manipulation of controls, let's review all of them step by step. You can refer to the following diagram for a quick overview of the class hierarchy:

Controls overview

As you can see, all ol.control.* classes inherit from ol.control.Control.

So, first let's see this ol.control.Control.

The ol.control.Control class

The ol.control.Control is the parent class of all the available controls. It inherits from ol.Object, an abstract class that also inherits from ol.Observable, a convenient class to provide and manage listeners.

Control options

This object is responsible for the common options that all controls contain. All controls inherit from ol.control.Control, and it's exactly the same for the options. To understand its properties, just review how a control can be described.

"A control is a DOM element related to the map and that can be attached to an existing DOM element."

If you refer to the following table. The DOM element is the element property, the place that contains the look for the control. The target property is the place where you add the element into the DOM.

Name

Type

Description

element

Element | undefined

This element is the control's container element. This only needs to be specified if you're developing a custom control.

target

Element | string | undefined

Specify a target if you want the control to be rendered outside of the map's viewport.

Never forget that it is useful to know ol.control.Control to understand its subclasses, but you never directly use it. You reuse this class only if you need to create your own control but it's not the time for this. First, we need to study controls provided by the Openlayers 3 library, which will be explained in the following sections.

The ol.control.Attribution control

The ol.control.Attribution control is not very new. We are already using it implicitly since we used the ol.layer.OSM class in Chapter 1, Getting Started with OpenLayers.

Attribution options

These are the options concerning the ol.control.Attribution control.

You can see all properties you can set for the control. You should be aware that those properties are considered as experimental in the OpenLayers 3 release.

Name

Type

Description

className

string | undefined

This property sets the CSS class name for the control. The default value is ol-attribution.

target

Element | undefined

This option sets the target to the DOM element where you want to display your control.

collapsible

boolean | undefined

This specifies whether attributions can be collapsed. If you use an OSM source, this should be set to false—see OSM Copyright. The default value is true.

collapsed

boolean | undefined

This specifies whether attributions should be collapsed at startup. The default value is true.

tipLabel

string | undefined

This is the text label to use for the button tip. The default value is Attributions.

label

string | undefined

This is the text label to use for the collapsed attributions button. The default value is i.

collapseLabel

string | undefined

This is the text label to use for the expanded attributions button. The default value is ».

We will discover the way to customize it in the following section.
