jtabbedpane

I have JTabbedPane with many generated dynamically JPanels, that contains JTable. How can i get/set JTable from the selected JTabbedPane tab? Already tried to use JTabbedPane.getComponents(), but it doesn't contain any JTable components. myPane.getSelectedComponent().getComponents(); will give you all components of the selected tab's component. You can search with a loop for the class JTable, if there is more than 1 component in your JPanel. 来源： https://stackoverflow.com/questions/20145916/get-jtable-from-selected-tab-at-jtabbedpane

When one of the panels present in a JTabbedPane is clicked, I need to perform a few actions at the start. Say, for example, I need to check the username and password. Only if those match, the particular panel operations need to be performed. Can you suggest any methods? Adamski Not sure I fully understand your question, but I would do something like: Add a ChangeListener to the JTabbedPane to listen for the first tab click. When a ChangeEvent occurs perform the login on a background thread using a SwingWorker. If the login is successful perform the required UI operations on the Event dispatch

I want to customize the look of the tabs in JTabbedPane. I want to start from the simplest and plainest behavior: no borders, solid color. The problem is that a non-plainess still remains: the tabs slight margin overlap. You see that since the second tab is selected, it is "brought to the fore". This is achieved by a slight margin overlap. Is there a (non tricky) way to disable this behavior? simple, testable (just fix imports) code: public class TabbedPane_LookStudy extends JFrame{ public static void main(String [] args) throws UnsupportedLookAndFeelException { UIManager.setLookAndFeel(new

I want to make my tab labels share the JTabbedPane width. If there's one tab, fit whole width, if two tabs, share width, if three, 1/3 for each and so on... i don't even know if it's possible to do it without putting a component there and resizing it, maybe JTabbedPane has a way of resizing it's tab label via method and i don't know... Anyone got any idea how to make it by the easiest way possible? As @trashgod already noted, the tab layout is handled by the LAF-specific SomeLAFTabbedPaneUI, more specifically the TabbedPaneLayout. So the way to go is implement a custom subclass

I am preparing a window with some horizontal tabs using JTabbedPane, Tabs And window are prepared properly. Now I need to setup these tabs in level basis, based on my requirement (My logic returns integer value based on that I need to setup levels ). Levels look like : Can you please advise? Just the sight of screenshot: import java.awt.*; import java.awt.event.*; import javax.swing.*; public class TabHeightTest { public JComponent makeUI() { JTabbedPane tabbedPane = new JTabbedPane( JTabbedPane.TOP, JTabbedPane.SCROLL_TAB_LAYOUT); tabbedPane.setUI(new javax.swing.plaf.basic.BasicTabbedPaneUI(

I am missing the blue horizontal divider between the tabs and the content in a Nimbus L&F TabbedPane set to SCROLL (other L&Fs (default & windows) provide those). As you can see the problem is limited to new JTabbedPane(JTabbedPane.TOP, JTabbedPane.SCROLL_TAB_LAYOUT) (top of the picture) while the default with WRAP does not show this behaviour (bottom of the picture). It should be possible to change something like this by overriding parts of the NimbusDefaults.class . Here is an excerpt: //Initialize TabbedPane d.put("TabbedPane.contentMargins", new InsetsUIResource(0, 0, 0, 0)); d.put(

I'm trying to prevent the user from changing a tab when the current tab is not valid. So when he clicks on a tab, I want to check if the current one is "valid", and if not, stay on the current tab. I tried to use a VetoableChangeListener which didn't work, the code never goes inside the vetoableChange method: jTabbedPane.addVetoableChangeListener(new VetoableChangeListener() { @Override public void vetoableChange(PropertyChangeEvent evt) throws PropertyVetoException { if (!isCurrentTabValid()) { throw new PropertyVetoException("test", evt); } } }); How can I do this properly? Thanks! A

Is it possible to add a button to a tabbed pane like in firefox. The plus-button is what I want. Thanks 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" :) user2287966 You can try this: public static void main (String[] args) { JFrame parent = new JFrame (); final JTabbedPane pane = new JTabbedPane (); pane.addTab (

I have two JTabbedPanes, JTabbedPane1 & 2 How can I press button in JTabbedPane2 to show JTabbedPane1 ? Here is the code for JTabbedPane: public class TabbedPane extends JFrame { public TabbedPane() { setTitle("Tabbed Pane"); setSize(300,300); JTabbedPane jtp = new JTabbedPane(); getContentPane().add(jtp); JPanel1 jp1 = new JPanel1();//This will create the first tab JPanel jp2 = new JPanel2();//This will create the second tab //add panel ......... //example usage public static void main (String []args){ TabbedPane tab = new TabbedPane(); } } here is class JPane1: ... JLabel label1 = new JLabel
