check if the collapsing node has its child selected, if so take a row
2004-01-20 JP Rosevear <jpr@ximian.com> * e-source-selector.c (test_collapse_row_callback): check if the collapsing node has its child selected, if so take a row reference to remember the selection (row_expanded_callback): check if the expanding node has the saved primary selection under it and re-select if so (init): listen for signals (impl_dispose): free the primary selection svn path=/trunk/; revision=24329
