View.Hover Property
Gets or sets the identity of the currently hovered feature.
Syntax
public Id Hover { get; set; }Property Value
Default: 0,0
The identity of the currently hovered feature, or [0, 0] if no feature is hovered.
Remarks
Just like the view keeps a list of identities of selected features and plots, it also keeps a single identity of a "hovered" feature and a "hovered" plot, meaning the feature or plot currently under the mouse cursor. The StandardTool and StandardTool3D will automatically track the mouse cursor, and when it passes a selectable feature or plot on the map display, the tools will set this and the HoverPlot property and the on the view to the identity of that feature or plot.
The idea is that you can then change the visualization of the feature or plot when it is hovered, to highlight it in some way. To do this for a hovered feature you should add one or more visualizers to the VisualizationOperator.HoverVisualizers in the layer the feature belongs to. Some of the map configuration samples in the Carmenta Engine SDK use this feature, take a look at the animations.px sample configuration for instance.
To clear this property, set it to a default constructed Id instance.
