gtk-tree-view-set-tooltip-cell (view tooltip path column renderer)

view -- a gtk-tree-view widget
tooltip -- a gtk-tooltip object
path -- a gtk-tree-path instance or nil
column -- a gtk-tree-view-column object or nil
renderer -- a gtk-cell-renderer or nil

Sets the tip area of tooltip to the area path, column and renderer have in common. For example if path is nil and column is set, the tip area will be set to the full area covered by column. See also the function gtk-tooltip-set-tip-area.

Note that if path is not specified and renderer is set and part of a column containing the expander, the tooltip might not show and hide at the correct position. In such cases path must be set to the current node under the mouse cursor for this function to operate correctly.

See also the function gtk-tree-view-tooltip-column for a simpler alternative.
