[SOLVED] Multiple CellRenderers in one column

Hi there!

Can someone give me an idea how to make TreeView where one of the columns will be rendered by CellRendererText OR CellRendererToggle (but not both!)
Maybe there is a signal or some callbact where I can plug-in and choose proper CellRenderer?

My code is actually in GTK# but any input will be appreciated!

Hello and welcome to the GTK+ forums!

This can be done by simply packing both cell renderers to the column and then selectively hiding one of them. There are different approaches to this selective hiding and the best one will depend on type of application being written. I wrote a simple implementation below that uses separate columns to hold visibility flags.

Code:

#include <gtk/gtk.h>

enum
{
  C_TEXT,
  C_TEXT_VIS,
  C_CHECK,
  C_CHECK_VIS,
  NO_COLS
};

static void
fill_treeview (GtkTreeView *view)
{
  GtkListStore *store;
  GtkCellRenderer *cell;
  GtkTreeViewColumn *col;

  char string[] = "Line 0";
  int i;


  store = gtk_list_store_new (NO_COLS, G_TYPE_STRING, G_TYPE_BOOLEAN,
                              G_TYPE_BOOLEAN, G_TYPE_BOOLEAN);
  for (i = 0; i < 10; i++)
    {
      GtkTreeIter iter;

      gtk_list_store_append (store, &iter);

      if (i % 2)
        {
          g_print ("%s\n", string);
          string[5] = i + '0';
          gtk_list_store_set (store, &iter,
                              C_TEXT, string,
                              C_TEXT_VIS, TRUE,
                              C_CHECK_VIS, FALSE,
                              -1);
        }
      else
        {
          gtk_list_store_set (store, &iter,
                              C_CHECK, !(i % 4),
                              C_CHECK_VIS, TRUE,
                              C_TEXT_VIS, FALSE,
                              -1);
        }
    }

  col = gtk_tree_view_column_new ();

  cell = gtk_cell_renderer_text_new ();
  gtk_tree_view_column_pack_start (col, cell, TRUE);
  gtk_tree_view_column_set_attributes (col, cell,
                                       "text", C_TEXT,
                                       "visible", C_TEXT_VIS,
                                       NULL);

  cell = gtk_cell_renderer_toggle_new ();
  gtk_tree_view_column_pack_start (col, cell, TRUE);
  gtk_tree_view_column_set_attributes (col, cell,
                                       "active", C_CHECK,
                                       "visible", C_CHECK_VIS,
                                       NULL);

  gtk_tree_view_append_column (view, col);
  gtk_tree_view_set_model (view, GTK_TREE_MODEL (store));
  g_object_unref (store);
}

int
main (int    argc,
      char **argv)
{
  GtkWidget *window,
            *treeview;

  gtk_init (&argc, &argv);

  window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  g_signal_connect (window, "destroy", gtk_main_quit, NULL);

  treeview = gtk_tree_view_new();
  gtk_container_add (GTK_CONTAINER (window), treeview);

  fill_treeview (GTK_TREE_VIEW (treeview));

  gtk_widget_show_all (window);

  gtk_main ();

  return 0;
}

Cheers,
Tadej

Thank You very much for Your effort, I wasn't expecting whole code:)
I get a principle now, just have port it to gtk#, shouldn't be too hard.

Cheers.

EDIT
Port'd!
