If the layer is lockable this allows the user to toogle the state of the locking for the layer. A lockable layer is a layer that has the ability to disable the scale ranges that are applied to a layers display, allowing a user to view the layer outside of it's normal scale ranges. To create a lockable layer you need to duplicate the layer in the underlying map engine, rename the new layer to include UNLOCKED as a prefix (or :UNLOCKED as a suffix) and remove any scale ranges that are attached to the symbology for the new layer. Then when Weave attempts to display the layer in an unlocked state it will display the unlocked version of the layer rather than the original. Note, you should not include the unlocked version of the layer in the ToC model.

Layer Transparency Slider

The weave.toc.layerTransparency context menu item was added at 2.5.21, this item adds a new slider to the context menu allowing you to directly change the transparency of the underlying map engine. Note that the slider is attached to individual layers in the ToC panel but it changes the transparency for the entire map engine that the layer belongs to and not just the layer associated with the ToC entry.

You can either specify the mapEngine and slider settings within a mapEngines and sliders section, as in the example, or specify them directly under the item.

You can also specify width and interval, either at the action level or the slider level, to specify the width of the slider and the movement interval of the slider.

Note that the tool currently only works on a layer entry in a ToC, and will not be available for a group, even if that group is set as not expandable. This has been resolved and will be available from 2.5.23.
