gtk:tree-view-scroll-to-cell (view path column &optional row-align col-align)

view -- a gtk:tree-view widget
path -- a gtk:tree-path instance of the row to move to, or nil
column -- a gtk:tree-view-column object to move horizontally to, or nil
row-align -- an optional float with the vertical alignment of the row specified by path, the default is 0.5
col-align -- an optional float with the horizontal alignment of the column specified by column, the default is 0.5

Moves the alignments of the tree view to the position specified by column and path. If the column argument is nil, then no horizontal scrolling occurs. Likewise, if the path argument is nil no vertical scrolling occurs. At a minimum, one of column or path need to be non-nil. The row-align argument determines where the row is placed, and the col-align argument determines where column is placed. Both are expected to be between 0.0 and 1.0. The 0.0 value means left/top alignment, the 1.0 value means right/bottom alignment, and the 0.5 value means center.

If the cell is currently visible on the screen, nothing is done.

This function only works if the model is set, and path is a valid row on the model. If the model changes before the tree view is realized, the centered path will be modified to reflect this change.
