如何在C中高亮显示GTKTreeView行，就像用鼠标选中一样

#include <gtk/gtk.h>

// 信号处理函数，用于在选中行时触发
void on_row_selected(GtkTreeView *treeview, GtkTreePath *path, GtkTreeViewColumn *column, gpointer userdata)
{
    GtkTreeModel *model;
    GtkTreeIter iter;
    GdkWindow *window;
    GdkRectangle rect;

    // 获取选中行的模型和迭代器
    model = gtk_tree_view_get_model(treeview);
    if (gtk_tree_model_get_iter(model, &iter, path))
    {
        // 获取选中行的窗口
        window = gtk_tree_view_get_bin_window(treeview);

        // 获取选中行的可见区域
        gtk_tree_view_get_visible_rect(treeview, &rect);

        // 将窗口坐标转换为控件坐标
        gtk_tree_view_convert_bin_window_to_widget_coords(treeview, rect.x, rect.y, &rect.x, &rect.y);

        // 获取选中行的单元格区域
        gtk_tree_view_get_cell_area(treeview, path, column, &rect);

        // 在选中行的区域内进行重绘，实现高亮显示效果
        gtk_widget_queue_draw_area(GTK_WIDGET(treeview), rect.x, rect.y, rect.width, rect.height);
    }
}

int main(int argc, char *argv[])
{
    gtk_init(&argc, &argv);

    // 创建GTK窗口
    GtkWidget *window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_default_size(GTK_WINDOW(window), 400, 300);
    g_signal_connect(window, "destroy", G_CALLBACK(gtk_main_quit), NULL);

    // 创建GTKTreeView
    GtkWidget *treeview = gtk_tree_view_new();
    gtk_container_add(GTK_CONTAINER(window), treeview);

    // 创建数据模型
    GtkListStore *store = gtk_list_store_new(1, G_TYPE_STRING);
    GtkTreeIter iter;
    gtk_list_store_append(store, &iter);
    gtk_list_store_set(store, &iter, 0, "Hello, World!", -1);

    // 设置数据模型
    gtk_tree_view_set_model(GTK_TREE_VIEW(treeview), GTK_TREE_MODEL(store));

    // 创建列和单元格渲染器
    GtkTreeViewColumn *column = gtk_tree_view_column_new();
    gtk_tree_view_append_column(GTK_TREE_VIEW(treeview), column);
    GtkCellRenderer *renderer = gtk_cell_renderer_text_new();
    gtk_tree_view_column_pack_start(column, renderer, TRUE);
    gtk_tree_view_column_set_attributes(column, renderer, "text", 0, NULL);

    // 注册信号处理函数
    g_signal_connect(treeview, "row-activated", G_CALLBACK(on_row_selected), NULL);

    gtk_widget_show_all(window);
    gtk_main();

    return 0;
}
