我试图将JavaFx浏览器组件添加到我的swing应用程序中。我需要在选项卡式窗格中加载浏览器，并在运行时动态地将url设置为这些浏览器。所以我有以下代码将浏览器渲染到JFrame中，但输出不会以帧的大小显示。浏览器组件在选项卡窗格内以小尺寸显示，而不是以全帧大小显示。请指导我在哪里，从下面的代码来纠正：从Main类的JFrame中的另一个类的JPanel的大小问题

loadURL(txtURL.getText());

btnGo.addActionListener(al);
txtURL.addActionListener(al);
progressBar.setPreferredSize(new Dimension(150, 18));
