jtabbedpane

问题 I'm working in with a JTabbedPane, I need to add a close button in the tabs to close the current one. I have been searching and as I understand I must extend from JPanel and add the close button as they say here But, is there a way to add the close buttons extending JTabbedPane or is there a easier way to do it? Thanks in advance, I really appreciate your time and your help. 回答1: Essentially, you're going to need to supply a "renderer" for the tab. Take a look at JTabbedPane.setTabComponentAt

问题 Is it possible to add a button to a tabbed pane like in firefox. The plus-button is what I want. Thanks 回答1: I think you should be able to manage it by building your own JTabbedPaneUI and setting it on the JTabbedPane using setUI . Your ComponentUI has methods to get a hold of the accessible children. If you specify a JButton and a JLabel then you may be in business. I haven't attempted this myself though. This is "at your own risk" :) 回答2: You can try this: public static void main (String[]

问题 I'm currently using a JFrame to hold a JTabbedPane that contains multiple tables. In my class that extends JFrame and implements TableModelListener , I have an onChanged() method that takes a TableModelEvent as an argument. I can successfully obtain data from the event on the table that the event was fired from, but I can't determine which table it was. From what I understand, this is not the way to do what I intend to do. I believe that I may need to write a custom TableModelListener or

问题 I am working with an application that is experiencing painting issues on some users computers when the mouse passes over the tabs in a JTabbedPane. They also occasionally have similar issues on other interactive components like JButtons. I have only ever seen this error occur on mouse overs.
