populate gtk tree view from outside

2012-09-12 Thread Rudra Banerjee 

Dear friends,
I have defined a treeview model as follows:

enum
{
  COL_FIRST_NAME = 0,
  COL_LAST_NAME,
  COL_YEAR_BORN,
  NUM_COLS
} ;

static GtkTreeModel *
create_and_fill_model (void)
{
  GtkTreeStore  *treestore;
  GtkTreeItertoplevel, child;

  treestore = gtk_tree_store_new(NUM_COLS,
 G_TYPE_STRING,
 G_TYPE_STRING,
 G_TYPE_UINT);

int i;
FILE *fauth; 
char alst[10][500], buffer[500];
fauth=fopen(fauth.dat,r);
if(!fauth){
printf(fauth failed\n);
}

while(fgets(buffer,500,fauth)){
strcpy(alst[i],buffer);
i++;
}
fclose(fauth);

for (i = 0; i  10; i++){
  gtk_tree_store_append(treestore, toplevel, NULL);
  gtk_tree_store_set(treestore, toplevel,
 COL_FIRST_NAME, alst[i],
 COL_LAST_NAME, Average,
 COL_YEAR_BORN, (guint) 1962,
 -1);
}

  return GTK_TREE_MODEL(treestore);
}


static GtkWidget *
create_view_and_model (void)
{
  GtkTreeViewColumn   *col;
  GtkCellRenderer *renderer;
  GtkWidget   *view;
  GtkTreeModel*model;
  view = gtk_tree_view_new();
  col = gtk_tree_view_column_new();
  gtk_tree_view_column_set_title(col, First Name);
  gtk_tree_view_append_column(GTK_TREE_VIEW(view), col);
  renderer = gtk_cell_renderer_text_new();
  gtk_tree_view_column_pack_start(col, renderer, TRUE);
  gtk_tree_view_column_add_attribute(col, renderer, text,
COL_FIRST_NAME);
   gtk_tree_view_column_pack_start(col, renderer, TRUE);
  model = create_and_fill_model();
gtk_tree_view_set_model(GTK_TREE_VIEW(view), model);
  g_object_unref(model); 

gtk_tree_selection_set_mode(gtk_tree_view_get_selection(GTK_TREE_VIEW(view)),
  GTK_SELECTION_NONE);
  return view;
}
//For brevity, I have cut out the 2nd and 3rd column



In a different function, I have


  strAuth = gtk_entry_get_text(GTK_ENTRY(e-entryAuth));
strEditor = gtk_entry_get_text(GTK_ENTRY(e-entryEditor));


Is it possible to add these strAuth, strEditor in those treeview's 1st
and 2nd column?

just acquire an iterator at the right position, and set the columns, for
example

gtk_tree_model_get_iter_first(GTK_TREE_MODEL(treestore), iter);
gtk_tree_store_set(treestore, iter,
  COL_FIRST_NAME, strAuth,
  COL_LAST_NAME, strEditor,
  -1);

 Oliver,
 Thanks for your reply.
 The problem basically is to pass on the function argument from one to
 other.

you need to create a header file (main.h) that has the enum, and
extern GtkListStore *treestore;

in main.c define GtkListStore *treestore; somewhere in the top of fthe
file, *not* inside a function.

then include this both in main.c and in otherfile.c like #include main.h

Oliver,
Thanks a lot. Its working properly.
Only change that I have made is using gtk_tree_store_append in place of
gtk_tree_model_get_iter_first.
Thanks a lot again.
