Debug窗口的底部显示Ruby解释器在端口1098上广播调试信息,RDT在这个端口上监听调试信息。
The bottom of the debug window shows that the Ruby interpreter broadcasts debugging information on port 1098, and the RDT listens on that port for debugging information.
此监听器可以作为一个 KeyListener 添加到树中,这样,当用户输入一些内容并选中树的一个项目时,输入窗口将会显示如图 7 所示的结果。
This listener can be added to the tree as a KeyListener, so that when a user types something while one of the tree’s items is selected, an input window displays as shown in figure 7.
