Connect to TestCollapseRow signal.

The given row is about to be collapsed (hide its children nodes). Use this signal if you need to control the collapsibility of individual rows.

Parameters

`callback`	signal callback delegate or function to connect `bool callback(gtk.tree_iter.TreeIter iter, gtk.tree_path.TreePath path, gtk.tree_view.TreeView treeView)` `iter` the tree iter of the row to collapse (optional) `path` a tree path that points to the row (optional) `treeView` the instance the signal is connected to (optional) `Returns` false to allow collapsing, true to reject
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)

Returns

Signal ID
