Line :: type - Get current line type
The function returns the line type of the line currently selected in a list or tree. A line in a tree is either a head line (static line) or a data line. When the control is not a list or tree control, the function returns LT_undefined.
When no line is attached, the function throws an exception.
Notes:
In OSI, the string value (name) from the enumerator will be returned rather than the code value.
Return value: Line type ( odabagui::LineTypes )
The line type describes the type of an item in a list or tree.
