Re: [anjuta-list] using gtktreeview and gtkliststore in Anjuta

[Ian Liu Rodrigues <ian liu88 gmail com>]

You must create columns and then you need to pack GtkCellRenderer's in it.
This is a simplified model:

TreeView may contain several TreeViewColumns
TreeViewColumns may contain several CellRenderer's

CellRenderer's show data from TreeModel columns

So, you must create columns and then create cell renderers under the column to show data.

See http://scentric.net/tutorial/treeview-tutorial.html

In glade, you can achieve this by right-clicking your column and selecting the apropriate cell renderer.
After that, you must bind a column from the model with a cell renderer property.

I tried that, and it still doesn't work. I created a test program. It
just has a TreeView, an "Add" button, a "Remove" button and a "Clear"
button, and a spin button to choose an integer value. When I click the
"Add" button, it should read the integer value in the spin button and
put it in the liststore. When I do that, though, I get the following
Gtk warning in the terminal:

Gtk-WARNING **: /build/buildd/gtk+2.0-2.22.0/gtk/gtkliststore.c:797:
Invalid column number -1077906408 added to iter (remember to end your
list of columns with a -1)

Also, when I add rows to the liststore using Glade, they still don't
show up, either.

Here's a link to a tarball of the test project code:
