# Class: Projection

[layers](/solutions/geotoolkit/geotoolkit_js/apis/modules/geotoolkit.map#layers).[Projection](/solutions/geotoolkit/geotoolkit_js/apis/modules/geotoolkit.map#projection).Projection

Projection layer is used to transform and display rectangular nodes on the map projection.

#### enableEventPropagation

▸ **enableEventPropagation**(`enable`): [`Projection`](/solutions/geotoolkit/geotoolkit_js/apis/classes/geotoolkit.map.layers.projection.projection)

Enable event propagation from the node hierarchy from bottom to top
<p>
This option is similar to DOM Event bubbling, which allows
to get any event from child node. By default it is disabled
for better performance.
</p>

**`Example`**

```ts
import {Group} from '@int/geotoolkit/scene/Group';
import {Events as SceneEvents} from '@int/geotoolkit/scene/Node';
const parentGroup = new Group()
.setName('ParentGroup')
.enableEventPropagation(true);
const childGroup = new Group()
.setName('ChildGroup');

parentGroup.addChild(childGroup);
parentGroup.on(SceneEvents.Invalidate, (eventName, sender, args) =&gt; {
// Got notifications from all children of parent group
});
childGroup.invalidate();
```

#### Parameters

| Name  | Type  | Description  |
|  --- | --- | --- |
| `enable` | `boolean` | enable |


#### Returns

#### execute

▸ **execute**(`delegate`): [`Projection`](/solutions/geotoolkit/geotoolkit_js/apis/classes/geotoolkit.map.layers.projection.projection)

Executes delegate and return the result. It allows us to keep all initialization calls in one place, <br>
and we do not need to scroll up or down in IDE to find how and where it was initialized.

**`Example`**

```ts
// All setters (.setName() for example) returns reference to the this.
// In order to modify inner object like LineStyle or Pattern, to get this object (property) we should call getter to get object reference.
// Then modify it as shown below in Option 1 or you can use execute methods shown in Option 2.
import {Group} from '@int/geotoolkit/scene/Group';
import {Rect} from '@int/geotoolkit/util/Rect';
// Option 1
const group = new Group()
.setName('MyGroup')
.setBounds(new Rect(0, 0, 42, 16))
.enableClipping(true)
.setTag({'type': 'sometype'});

group.getLineStyle().setPattern('pattern');
return group;

// Options 2 ( using execute method )
return group
.execute(function () {
this.getLineStyle()
.setPattern("pattern");
});
```
