TreeView.getBackgroundArea

void getBackgroundArea(gtk.tree_path.TreePath path,  gtk.tree_view_column.TreeViewColumn column,  out  gdk.rectangle.Rectangle rect)

Fills the bounding rectangle in bin_window coordinates for the cell at the row specified by path and the column specified by column. 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.CellRenderer.render]. These background areas tile to cover the entire bin window. Contrast with the cell_area, returned by [gtk.tree_view.TreeView.getCellArea], which returns only the cell itself, excluding surrounding borders and the tree expander area.

Parameters

`path`	a #GtkTreePath for the row, or null to get only horizontal coordinates
`column`	a #GtkTreeViewColumn for the column, or null to get only vertical coordiantes
`rect`	rectangle to fill with cell background rect
