Method
Gtk.TreeView.scroll_to_cell
Declaration [src]
void
gtk_tree_view_scroll_to_cell (
GtkTreeView* tree_view,
GtkTreePath* path,
GtkTreeViewColumn* column,
gboolean use_align,
float row_align,
float col_align
)
Description [src]
Moves the alignments of tree_view to the position specified by column and
path. If column is NULL, then no horizontal scrolling occurs. Likewise,
if path is NULL no vertical scrolling occurs. At a minimum, one of column
or path need to be non-NULL. row_align determines where the row is
placed, and col_align determines where column is placed. Both are expected
to be between 0.0 and 1.0. 0.0 means left/top alignment, 1.0 means
right/bottom alignment, 0.5 means center.
If use_align is FALSE, then the alignment arguments are ignored, and the
tree does the minimum amount of work to scroll the cell onto the screen.
This means that the cell will be scrolled to the edge closest to its current
position. 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.
