问题 I want to change tabs location from left to center. How can I do this? I think I must change Look&Feel, but I don't know how. From this: To this: 回答1: As you already pointed out, you have to use an LookAndFeel which supports this design (centered Tab-Button). When your selected LaF does not support this, you have to write your own TabbedPaneUI. (But this may not be very easy.) If you do not want to create your own TabbedPaneUI, you have to look for an existing custom TabbedPaneUI or

问题 i am trying to create GUI using java swings.I am just a beginner in java swings. My primary idea was to create two tabs and add a button in one of the tabs. I wanted to write a separate class for each tab so i created 3 classes out of which one has the main method.and the other two represent the tabs. In one of the tabs i wanted to add a button in middle and add an action listener to that button. below is the class which has the main method. public class abc { JFrame frame; JTabbedPane

Get the in-focus tab after closing a tab

In a JTabbedPane, I associated a custom-made Data object to each added tab. I also have a corresponding Metadata object that shows up in another panel when the tab is selected. The problem I have now is when a tab is closed, the metadata panel shows the metadata of the Data object in the tab that just gets closed. Ideally, I want the panel to show the metadata for the in-focus tab that the user sees. However, the act of closing a tab means the “selected tab” is the tab being closed, so tabpane.getSelectedIndex() would not work. How can I get the tab that is in focus after closing a tab? Thank

问题 I have an application with several components. One of them is a JTabbedPane with other stuff in it (obviously).

Tab in JTabbedPane does not reflect changes on button press

问题 Within a tab of my GUI, the user is allowed to edit an employee's name. The name also serves as the tab's label, so when the change is confirmed the tab should be updated to reflect this change and the new data is written to a data file. The employees are stored in a HashMap in the class Employees . The tabs are populated by iterating through an ArrayList<String> of employees' names, which is gotten from calling the method Employees.getNames() . From the GUI, the user can type in a new name
