to_string

Serializes a `PangoTabArray` to a string.

In the resulting string, serialized tabs are separated by newlines or commas.

Individual tabs are serialized to a string of the form

[ALIGNMENT:]POSITION[PangoTabArray:DECIMAL_POINT]

Where ALIGNMENT is one of _left_, _right_, _center_ or _decimal_, and POSITION is the position of the tab, optionally followed by the unit _px_. If ALIGNMENT is omitted, it defaults to _left_. If ALIGNMENT is _decimal_, the DECIMAL_POINT character may be specified as a Unicode codepoint.

Note that all tabs in the array must use the same unit.

A typical example:

100px 200px center:300px right:400px

Parameters:

this	a `PangoTabArray`

Returns:

a newly allocated string
