[Vala] Problems manipulating Gtk Treeview in Genie

["GALLOWAY Stuart J (SVHM)" <Stuart GALLOWAY svhm org au>]

Hi,

 

The problem:

I am converting a list managing program from pyGtk to Genie. 

I want to clear and reconstruct columns dynamically to suit various 2 dimensional tables.

I want to use Gtk.TreeView.get_columns  to clear the columns

I cant get this to compile:  I am using the windows port of valac 7.0

for col in treeview.get_columns()
            treeview.remove_column(col)

I tried assigning the columns to a list.  I could not do that until I installed libGee but it still does not want to assign to that list.

Can’t I use a Glib list?  Is a libGee list compatible with a Glib list?

Because Vala and Genie are statically typed I presume I would have to declare a list of  treecolumns.  How would I do that? Can I have an anonymous list and typecast each element?

Most things are converting nicely but I get stuck every so often.  Fantastic language but we need some more examples and documentation.

I am using Glade3 to develop the GUI and genie reads that without problems with Builder.  When I run the program (with problem areas commented out) I get a whole lot of warnings about about vertical orientation not being recognised. What is that about?
