Re: How to customize GtkCellRendererCombo ?




Hi Stefan,

I was not aware of this sample, and it turns out that this sample works fine. I rewrote the following function from my sample, and the combo works fine now:

void on_tree_cell_combo_editing_start(GtkCellRenderer *renderer, GtkCellEditable *editable, gchar *path, gpointer user_data)
{
    if (GTK_IS_COMBO_BOX(editable))  {
        GtkComboBox *combo = GTK_COMBO_BOX(editable);
GtkCellView *view = (GtkCellView *)gtk_bin_get_child(GTK_BIN(editable));
        GList *list = gtk_cell_view_get_cell_renderers(view);
        while (list){
            GtkCellRenderer *renderer1 = (GtkCellRenderer *)list->data;
            list = list->next;
gtk_cell_layout_set_cell_data_func(GTK_CELL_LAYOUT(combo), renderer1, TaskStatusComboCellData, NULL, NULL);
        }
    }
}

It seems that the renderer parameter being passed to this function is not to be touched.

Thank you very much for your help.

Regards,
  Miroslav

I was not really happy with that fix myself.

Seems to be a related task, but in php, so I can not really understand it well.

Maybe Emmanuele Bassi can help us tomorrow.
