gtk-flow-box-insert (flowbox child position)

flowbox -- a gtk-flow-box widget
child -- a gtk-widget child widget to add
position -- an integer with the position to insert the child widget in

Inserts the child widget into the flow box at a given position.

If a sort function is set, the widget will actually be inserted at the calculated position and this function has the same effect as the gtk-container-add function.

If the position argument is -1, or larger than the total number of children in the flow box, then the child widget will be appended to the end.
