GTK gossip: gtktreeview and gtktreestrore

With Gtktreeview and Gtkliststore In the following example Gtktreeview and Gtkliststore Createmodel () in the example, convert Gtkcombobox And gtktreestore The createmodel () function in does not change, that is Gtkcombobox And gtktreestore Show the external volume of gtktreeview on the model worker in : Gtk_tree_view_with_tree_store.c #include <gtk/gtk.h> enum { PIXBUF_COL, TEXT_COL }; GtkTreeModel* createModel() { const gchar *files[] = {"caterpillar.jpg", "momor.jpg", "hamimi.jpg", "bush.jpg"}; gchar *stocks[] = { GTK_STOCK_DIALOG_WARNING, GTK_STOCK_STOP, GTK_STOCK_NEW, GTK_STOCK_CLEAR, GTK_STOCK_OPEN }; gchar *stockNames[] = { "WARNING", "STOP", "NEW", "GTK_STOCK_CLEAR", "GTK_STOCK_OPEN" }; GtkWidget *cellView; GdkPixbuf *pixbuf; GtkTreeIter iter1, iter2; GtkTreeStore *store; gint i, j, s; store = gtk_tree_store_new(2, GDK_TYPE_PIXBUF, G_TYPE_STRING); cellView = gtk_cell_view_new(); for(i = 0; i < 4; i++) { pixbuf = gdk_pixbuf_new_from_file(files[i], NULL); gtk_tree_store_append(store, &iter1, NULL); gtk_tree_store_set(store, &iter1, PIXBUF_COL, pixbuf, TEXT_COL, files[i], -1); gdk_pixbuf_unref(pixbuf); for(j = 0; j < 3; j++) { s = rand() % 5; pixbuf = gtk_widget_render_icon(cellView, stocks[s], GTK_ICON_SIZE_BUTTON, NULL); gtk_tree_store_append(store, &iter2, &iter1); gtk_tree_store_set(store, &iter2, PIXBUF_COL, pixbuf, TEXT_COL, stockNames[s], -1); gdk_pixbuf_unref(pixbuf); } } return GTK_TREE_MODEL(store); } gboolean selection_changed(GtkTreeSelection *selection, GtkLabel *label) { GtkTreeView *treeView; GtkTreeModel *model; GtkTreeIter iter; gchar *active; treeView = gtk_tree_selection_get_tree_view(selection); model = gtk_tree_view_get_model(treeView); gtk_tree_selection_get_selected(selection, &model, &iter); gtk_tree_model_get(model, &iter, 1, &active, -1); gtk_label_set_text(label, active); } int main(int argc, char *argv[]) { GtkWidget *window; GtkWidget *treeView; GtkCellRenderer *renderer; GtkTreeViewColumn *column; GtkWidget *label; GtkWidget *vbox; GtkTreeSelection *selection; gtk_init(&argc, &argv); window = gtk_window_new(GTK_WINDOW_TOPLEVEL); gtk_window_set_title(GTK_WINDOW(window), "GtkTreeView"); gtk_window_set_default_size(GTK_WINDOW(window), 200, 50); treeView = gtk_tree_view_new_with_model(createModel()); renderer = gtk_cell_renderer_pixbuf_new(); column = gtk_tree_view_column_new_with_attributes( "Icon", renderer, "pixbuf", PIXBUF_COL, NULL); gtk_tree_view_append_column(GTK_TREE_VIEW (treeView), column); renderer = gtk_cell_renderer_text_new(); column = gtk_tree_view_column_new_with_attributes( "Filename", renderer, "text", TEXT_COL, NULL); gtk_tree_view_append_column(GTK_TREE_VIEW (treeView), column); label = gtk_label_new("caterpillar.jpg"); vbox = gtk_vbox_new(FALSE, 5); gtk_box_pack_start(GTK_BOX(vbox), treeView, TRUE, TRUE, 5); gtk_box_pack_start(GTK_BOX(vbox), label, TRUE, TRUE, 5); gtk_container_add(GTK_CONTAINER(window), vbox); selection = gtk_tree_view_get_selection(GTK_TREE_VIEW(treeView)); g_signal_connect(G_OBJECT(selection), "changed", G_CALLBACK(selection_changed), label); g_signal_connect(GTK_OBJECT(window), "destroy", G_CALLBACK(gtk_main_quit), NULL); gtk_widget_show_all(window); gtk_main(); return 0; } The results of a line are as follows:
