You could use JxBrowser. It features a Swing/JavaFX component that wraps the Chromium engine while providing a rich API and out-of-the-box hardware-acceleration through the GPU. Unfortunately, they’ve dropped support for other engines (like Gecko and WebKit) since 4.0 version. Note that it’s not free, except for open-source projects.

Here’s an alternate approach to modifying the TableCellRenderer of a table’s JTableHeader. It’s not strictly necessary for this usage, but it minimizes the impact on the UI delegate’s appearance. Typical usage: JTable table = new JTable(…); JTableHeader header = table.getTableHeader(); header.setDefaultRenderer(new HeaderRenderer(table)); Custom header renderer: private static class HeaderRenderer implements TableCellRenderer { DefaultTableCellRenderer renderer; public … Read more
I would get the JTextArea’s Document via getDocument() (a PlainDocument actually) and use a DocumentListener to listen for changes. This way you’d capture changes from key strokes and also from copy/paste/cut events.
Problems with your code and suggestions: Again you need to change the preferredSize of the component (here the Graph JPanel), not the size Don’t set the JFrame’s bounds. Call pack() on your JFrame after adding components to it and before calling setVisible(true) Your foreach loop won’t work since the size of your ArrayList is 0 … Read more

Using JDK8, you can set the apple.awt.application.name property to affect the Application menu name. However, Martijn Courteaux’s warning still applies: you must do this before any AWT classes are loaded. And AWT classes will be loaded before your main() method runs if it lives in a subclass of JFrame.
