IndexOfTab is an overloaded method in TCustomTabControl used to get the position for a tab located at the client client coordinates. The overloaded variants allow the client position to be specified as separate Integer values, or as a TPoint instance where the X and Y members contain the client-relative coordinates.
IndexOfTabAt calls the GetTabIndexAtPos method in the widgetset class to get the ordinal tab position in the return value. The return value is -1 if a tab is not visible at the specified coordinates, or when the handle has not been allocated for the widget instance.
Example Usage:
APos := TabControl1.IndexOfTabAt(TabControl1.ScreenToClient(Mouse.CursorPos));
