How to select a GtkCTree branch?

[learfox furry ao net]

How do I select a GtkCTree branch by code?  I tried gtk_ctree_select()
but it seems that I need one additional step to ensure that the selected
node branch is expanded.

How do I select and ensure that the branch is expanded (visible to the
user)?   This is for a find function where I have already found the
branch node pointer and want to select and ensure the user sees it.
