get_background_area
Description:
Fills the bounding rectangle in bin_window coordinates for the cell at the row specified by path and the column specified by
column.
Use [class@Gtk.ListView] or [class@Gtk.ColumnView] instead
If path is null, or points to a node not found in the tree, the y and height
fields of the rectangle will be filled with 0. If column is null, the x and
width fields will be filled with 0. The returned rectangle is equivalent to the background_area passed to
gtk_cell_renderer_render. These background areas tile to cover the entire bin window. Contrast with the cell_area,
returned by get_cell_area, which returns only the cell itself, excluding
surrounding borders and the tree expander area.
