Hi all,
I am trying to create a TreeView, of which a column should display a
combo box.
So I have listmodel ListModelA with a GTK_TYPE_TREE_MODEL in it and then
this model is filled with data. I add listmodels (ListModelB) with 2
columns to the listmodel ListModelA, previously created or possibly a
NULL pointer.
Then for the TreeView of ListModelA I create a GtkCellRendererCombo and
I use gtk_tree_view_column_set_cell_data_func so I can set the model
property of the cell renderer if the model retrieved from ListModelA is
not NULL. (LancetSectionSymbolCellRendererSetModel)
Then I set
g_object_set(renderer,"has-entry",FALSE, "text-column",
SYMBOL_NAME_COLUMN, "editable", FALSE, NULL);
When I look at the result, I get no warnings at run-time or
compile-time, but I don't see any Combo in the resulting TreeViewColumn.
What am I doing wrong?
I've included the (relevant part of the) source below.
Thanks for any help.
Ludo
