- [AssignTooltipFields](https://developer.rhino3d.com/api/gh1/type/grasshopper.gui.gh-tooltip/assigntooltipfields.md): (static) Set all fields of the Tooltip. You'll still need to call Show() to display the tooltip.

- [IsOwner](https://developer.rhino3d.com/api/gh1/type/grasshopper.gui.gh-tooltip/isowner.md): (static) Returns true if the test control matches the internal Owner control. Use this method to make sure you actually own this tooltip prior to clearing it.
