    <p><strong>Update:</strong> As was pointed out, the original answer did not directly answer the OP's question. I've created a <a href="http://clarkonium.net/2013/08/loading-fonts-like-css/" rel="nofollow">blog post</a> about the original technique in case anyone is interested.</p> <p>Here is a short program that does what you want.</p> <pre><code>(ns demo.core (:gen-class :extends javafx.application.Application) (:import [javafx.application Application] [javafx.event EventHandler] [javafx.scene Scene] [javafx.scene.control Button] [javafx.scene.layout StackPane] [javafx.scene.text Font]) (:require [clojure.java.io :as jio])) (defn- get-font-from-resource "Load the named font from a resource." [font-name] (let [prefix "demo/resources/" url (jio/resource (str prefix font-name)) fnt (Font/loadFont (.toExternalForm url) 20.0)] fnt)) (defn -start "Build the application interface and start it up." [this stage] (let [root (StackPane.) scene (Scene. root 600 400) fnt (get-font-from-resource "ITCBLKAD.TTF") btn (Button. "Press Me!")] (.setOnAction btn (reify EventHandler (handle [this event] (doto btn (.setText (str "This is " (.getName fnt))) (.setFont fnt))))) (.add (.getChildren root) btn) (doto stage (.setTitle "Font Loading Demo") (.setScene scene) (.show)))) (defn -main [&amp; args] (Application/launch demo.core args)) </code></pre> <p>In this project, I placed the font file in <code>resources</code>, a sub-directory of <code>demo</code> - where the Clojure source is stored - hence the "prefix" in the function <code>get-font-from-resource</code>.</p> <p>It looks like the problem you might have been having with <code>loadFont</code> was in your conversion from the <code>URL</code> to the <code>String</code> form. The external form is an absolute path starting at the root directory on the drive.</p> <p><strong>Tip</strong>: You probably know this, but one thing that continually screws me up are methods in JavaFX that require <code>double</code> parameters, like <code>Font/loadFont</code>. I'm used to Java just promoting integer arguments to double. In Clojure, if you use an integer where a double is required, the program fails with a less than useful error message.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
