onRowsReordered
open fun onRowsReordered(connectFlags: <Error class: unknown class> = ConnectFlags(0u), handler: (path: TreePath, iter: TreeIter, <Error class: unknown class>?) -> Unit): <Error class: unknown class>(source)
This signal is emitted when the children of a node in the GtkTreeModel have been reordered.
Note that this signal is not emitted when rows are reordered by DND, since this is implemented by removing and then reinserting the row.
Parameters
connectFlags
a combination of ConnectFlags
handler
the Callback to connect. Params: path a GtkTreePath identifying the tree node whose children have been reordered; iter a valid GtkTreeIter pointing to the node whose children have been reordered, or null if the depth of @path is 0; newOrder an array of integers mapping the current position of each child to its old position before the re-ordering, i.e. @new_order[newpos] = oldpos
