Layer Settings Panel

The layer settings panel is used to configure properties of a layer that do not directly affect its representation on the map. The data section allows you to choose a Feature Source resource to use as the source of data for this layer. All other properties of a layer are dependent on the feature source selected. You must select a feature source in order to configure and style a layer. If you choose to change the feature source associated with a layer, all properties and styling information will be lost, so only change the feature source for new layers or if you are really, really sure you want to.

Feature Data Setup

Feature Class

A feature source may provide one or more feature classes. Changing feature classes will remove any selected properties and styling information.

Geometry

A feature class may provide one or more geometries. Changing geometries will remove any existing styling information.

Properties

You can choose which attributes of the selected feature class will be visible to the user when a feature on this layer is selected. To make an attribute available, check the checkbox next to the property and supply a display name if desired.

Filter

You can select a layer-wide filter to apply to the feature source. This filter is used by the FDO provider to limit the features used to draw the layer. Use the [...] button to the right of the filter to open the expression builder and create a filter expression.

URL

Does anyone know what this does?

Tool tip

You can specify an expression used to display a tooltip when the user hovers the mouse over a feature on this layer. Use the [...] button to the right of the tool tip to open the expression builder and create a text expression.
