gtkTreeViewScrollToCell: gtkTreeViewScrollToCell
Description
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.Usage
gtkTreeViewScrollToCell(object, path, column = NULL, use.align = FALSE, row.align = 0, col.align = 0)
Arguments
path
The path of the row to move to, or NULL. [ allow-none ] use.align
whether to use alignment arguments, or FALSE.
row.align
The vertical alignment of the row specified by path.
col.align
The horizontal alignment of the column specified by column.
Details
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.
