Pops up the passed tip at the global coordinates given by x, y (relative to the screen). If AutoHide is True, then the tip will automatically hide itself; you do not have to call HideTooltip to hide it. The default is True.
Notes
AutoHide is used only on Windows and Linux; on macOS, the ToolTip hides automatically.
