Forum: Ruby-Gnome 2 Gtk::TreeViewColumn

I'm still  stuck with getting a undefined sort_column_id. For a
GtkTreeViewColumn
--------

irb(main):001:0> require 'gtk2'
=> true
irb(main):002:0> column = Gtk::TreeViewColumn.new
=> #<Gtk::TreeViewColumn:0x29dbde8 ptr=0x2c32840>
irb(main):003:0> column.sort_column_id = 1
NoMethodError: undefined method `sort_column_id=' for
#<Gtk::TreeViewColumn:0x29dbde8 ptr=0x2c32840>
       from (irb):3
       from /myscratch/ruby/bin/irb:12:in `<main>'

------------

This works on older Ruby, and "the latest greatest" Ruby + Ruby/GTK

Just on this one machine I have built the interpreter on that is back
to GTK 2.10

For reference, I am using this for my own "file selector" box, as I
need to apply my own sort.  This Gtk::TreeViewColumn is my file
listing. I may not be using the best way to do it. But it seems odd it
just fails on this one build. My build base was the latest(as of
yesterday) snapshot of Ruby/GTK from Github.

Short answer: I've commited Gtk::TreeViewColumn#sort_column_id=
support code on GTK+ 2.10 into master.

Long answer:

Ruby/GTK+ generates accessors from GObject's property
information automatically. For example, GtkTreeViewColumn
(it's a C level GObject) has the "sort-column-id" property:
  http://developer.gnome.org/gtk/stable/GtkTreeViewC...

Ruby/GTK+ generates

  * Gtk::TreeViewColumn#sort_column_id
  * Gtk::TreeViewColumn#sort_column_id=
  * Gtk::TreeViewColumn#set_sort_column_id

from the property.

The above page says the "sort-column-id" property is defined
"Since 2.18". So you don't have
Gtk::TreeViewColumn#sort_column_id= with GTK+ 2.10.

I've added codes that accesse sort-column-id value by the
following functions:

  * gtk_tree_view_column_set_sort_column_id()
    http://developer.gnome.org/gtk/stable/GtkTreeViewC...
  * gtk_tree_view_column_get_sort_column_id()
    http://developer.gnome.org/gtk/stable/GtkTreeViewC...

Now you can use Gtk::TreeViewColumn#sort_column_id= with
GTK+ 2.10.


Thanks,

Sorry for the long delay on reply. I just back to this. Thanks for the 
long
answer. Explains a lot. I see you did two different commits.

The first one allowed  me to do

 thing.set_sort_column_id(1)

But the next commit, that added the

RG_DEF_ALIAS(sort_column_id, set_sort_column_id);

Gives me the compile error:
rbgtktreeviewcolumn.c: In function 'Init_gtk_treeviewcolumn':
rbgtktreeviewcolumn.c:294: error: 'sort_column_id' undeclared (first use 
in
this function)
rbgtktreeviewcolumn.c:294: error: (Each undeclared identifier is 
reported
only once
rbgtktreeviewcolumn.c:294: error: for each function it appears in.)
rbgtktreeviewcolumn.c:294: error: 'set_sort_column_id' undeclared (first
use in this function)

Hello Kouhei, Grant

I believe it was easy to fix so I did it. Could you please check ?
