Switching a panel wthin a JTabbedPane

Thread view:

I am having a hard time replacing the content of a JPanel by another
one. Can't seem to see the JPanel that replaces the older JPanel within
a JTabbedPane. I am dynamically building a JPanel based on different
data requirements. Not sure what I am doing wrong. .updateUI() does not
show the new JPanel.

Simplified here is the main idea:

*Class_A*
protected static JPanel dummyPanel_A;

detailTabbedPane.addTab("Tab Title", null, new
JScrollPane(dummyPanel_A),"Tab Tip");

*Class_B*
protected static JPanel dummyPanel_B;

Make changes to dummyPanel_B then want to replace the Class_A panel
dummyPanel_A with dummyPanel_B (using Goodies Forms)

Class_A.dummyPanel = builder.getPanel();
Class_A.detailTabbedPane.updateUI();

Thanks in Advance...

Method updateUI() is supposed to be used when the look&feel of a
component has changed. Instead try Class_A.detailTabbedPane.revalidate();

The .revalidate() is not working. Can not understand it. I tried again
(below). Why can't I do say in Class_B:
*SelectedtabbedPane.dummyPanel_A = dummyPanel_B*

----------------------

*Class_A*
protected static JPanel dummyPanel_A;

detailTabbedPane.addTab("Tab Title", null, new
JScrollPane(dummyPanel_A),"Tab Tip");

... upon user tab Selection in Class_A
Class_B.retrieveIPInformation(someString,SelectedtabbedPane,dummyPanel_A)

*Class_B*
Make changes to dummyPanel_B then want to replace the Class_A panel
dummyPanel_A with dummyPanel_B in SelectedtabbedPane (using Goodies Forms)

protected static JPanel dummyPanel_B;

static void retrieveIPInformation(String insomeString,JTabbedPane
SelectedtabbedPane,dummyPanel_A )

..... Build the dummyPanel_B

dummyPanel_B = builder.getPanel();

..... Switch the dummyPanel_A

dummyPanel_A = dummyPanel_B;
..... or
Class_A.dummyPanel_A = dummyPanel_B;

SelectedtabbedPane.revalidate();

I guess my question is:

How can you update a JPanel that is embedded within a JScrollPane within
a JTabbedPane object from a different Class? Reflection? I am at a lost
to resolve with out a redesign.

Can't you keep a reference to the tabbedPane somewhere that your code can get
at. Then you just do:

myTabbedPane.setComponentAt( index, newComponent);

Bill...

Thank you so much! This does work.

I thought I tried this before. Apparently I did not have the correct
object reference. It does replace the component but I had it inside a
JScrollPane. After issuing the setComponentAt() it replaces the
JScrollPane(target_panel) with the new target_panel.

I am way a head of where I have been, with your help. To replace the
JScrollPane(target_panel), not just the panel I tried:

JScrollPane dummyJScrollPane = new JScrollPane(dummypanel_B);
SelectedtabbedPane.setComponentAt( 3, dummyJScrollPane);

Works like a charm....

Thanks again Bill...
