Hello, I'm trying to use a GtkCellRenderer of type
gtk_cell_renderer_pixbuf_new to render stock images (GTK_STOCK_...).
The code I have so far only segfaults, I've copied code off google
codesearch from gnomescan and they set the pixbuf's attribute to
"stock-id" then when storing elements in a ListStore they simply add
(GTK_STOCK_...) instead of using a GdkPixbuf.
Here is my code, I've kept it short so it could fit into the body of
an email nicely.
I think everything else works fine, remove line "COL_ICON,
GTK_STOCK_HOME," to see that the treeview works properly
Thank you
#include <gtk/gtk.h>
enum {
COL_ICON = 0, COL_TEXT, NUM_COLS
};
GtkListStore *create_liststore(void) {
GtkListStore *store;
GtkTreeIter iter;
store = gtk_list_store_new(2, GDK_TYPE_PIXBUF, G_TYPE_STRING);
gtk_list_store_append(store, &iter);
gtk_list_store_set(store, &iter,
COL_ICON, GTK_STOCK_HOME,
COL_TEXT, "Home",
-1);
return store;
}
GtkWidget *create_treeview(void) {
GtkTreeModel *model;
GtkTreeViewColumn *col;
GtkCellRenderer *renderer;
GtkWidget *view;
model = GTK_TREE_MODEL(create_liststore());
view = gtk_tree_view_new_with_model(model);
col = gtk_tree_view_column_new();
gtk_tree_view_column_set_title(col, "Column #1");
renderer = gtk_cell_renderer_pixbuf_new();
gtk_tree_view_column_pack_start(col, renderer, FALSE);
gtk_tree_view_column_add_attribute(col, renderer, "stock-id", COL_ICON);
gtk_cell_renderer_set_fixed_size (GTK_CELL_RENDERER (renderer), 16, 16);
renderer = gtk_cell_renderer_text_new();
gtk_tree_view_column_pack_start(col, renderer, TRUE);
gtk_tree_view_column_set_attributes(col, renderer,
"text", COL_TEXT,
NULL);
gtk_tree_view_append_column(GTK_TREE_VIEW(view), col);
return view;
}
gint main (gint argc, gchar **argv) {
GtkWidget *mainwindow, *vbox;
gtk_init(&argc, &argv);
mainwindow = gtk_window_new(GTK_WINDOW_TOPLEVEL);
g_signal_connect(mainwindow, "delete_event", gtk_main_quit, NULL);
gtk_container_add(GTK_CONTAINER(mainwindow), create_treeview());
gtk_widget_show_all(mainwindow);
gtk_main();
return 0;
