# Mixed Reality Toolkit - SDK - UX - Tooltips support As part of the Mixed Reality Toolkit SDK, we provide scripts / controls for managing and implementing tooltips in your Mixed Reality project. Currently we provide components for: ## Tooltips Manages the bulk of the tooltip display, content sizing and anchor behaviors. Also contains the text field for what a tooltip's text field should convey. * Provides a field to show the connected Line Data Provider (see Lines section) ## Lines Mixed Reality Toolkit has a line concept built on top of Unity's LineRenderer concept allowing for more expressive lines. Begin with a LineDataProvider (Such as SimpleLine, Spline, or Parabola). A tooltip will look for a LineDataProvider automatically and then attempt to use it to connect the tooltip to the indicated Anchor. The line appearance and behavior can be styled and controlled in a MixedRealityLineRenderer component. Note: Not all LineDataProviders will work with Tooltips in a predictable manner. * SimpleLine, Spline, ParabolaConstrained are the reasonable examples (and a prefab for each exists) * Ellipse, Rectangle, ParabolaLine and ParabolaPhysicalLine tend to be less reliable or produce non-useful results. ### TooltipSpawner A TooltipSpawner is a mostly standalone script that receives Focus or Input events (assuming it has a collider) that can be used to instantiate a tooltip at a particular location with certain behaviors. You can control the appear and vanish conditions as well as how it responds to input. If you are using a TooltipSpawner, customize the tooltip prefab in the [Tool Tip Prefab] field to change the line/tooltip appearance.
