The way I did it was :
focus = get_focus();
for ( cc=0; cc<Screen.size(); cc++ )
{
test = Screen[cc];
if ( focus->is_ancestor ( *test ) )
{
Screen[cc]->RemoveSelected();
}
}
Where Screen is a std::vector of pointers to tree views, owned by the
main window. You need to use the is_ancestor method because the focus
is on a row of the tree view.
Hope that helps,
Rob
