I'm currently trying to show the parts list tool tip when placed in the editor (VAB or SPH). Managed to display the popup using PartListTooltips::ShowTooltip(). That method, however, raises a null pointer exception after the first time the tool tip is hidden: NullReferenceException: Object reference not set to an instance of an object. Hovering over the part again generates another exception (showing the tooltip): ArgumentException: Getting control 0's position in a group with only 0 controls when doing Repaint Aborting. I'm guessing it has to do with the first argument of PartListTooltips::ShowTooltip(), which takes an EditorPartIcon object. The part information displays correctly - as if the mouse hovered over the part's icon in the parts list. However, I would like to know how to get rid of these exceptions and why/how this tooltip is working If anyone can shed some light on how to work with the parts editor list I would greatly appreciate it.
