I'm very new to PHP-GTK2, so this might be obvious to most people.

One piece of information relating to PHP-GTK2 specifically seems to be missing - the data type of $buffer in

Code:

$buffer = new GtkTextBuffer();

I have an array of (string) that I want to output, but I could easily have an array of array of (integer, string) if that is what $buffer is. It would save having to translate my array into $buffer every time something changes. But I can't find the definition of $buffer anywhere. Similarly using GtkTreeView without any hierarchy,

Code:

$buffer = new GtkTreeBuffer();

if the format of $buffer was made clear, I could use that directly. The sample codes all WANT to output the fields id, parent, data string, but I only want to output the data string. What is strictly necessary to have in $buffer ? Hope that makes sense.
