Getting jTextPane from selected tab of jTabbbedPane

Question

I am new to java Swing. I am trying to develop a tool, in which I used a Jtextpane as an editor. Jtextpane is enclosed in a Jtabbedpane to meet my requirement. But I have inserted the JTextpane in a Jscrollpane and then to the Jtabbedpane. Now, when I select a particular tab, I should get the corresponding Jtextpane. I have used the

jTabbedPane.getSelectedComponent();

But it returns the Jscrollpane. So, I am unable to save the contents in corresponding Jtextpane...

Can anybody plz help me to resolve this....

Thanks in Advance...

How about first getting the selected component of the tab (which is the scroll panel):

SQL

JScrollPane jscrollpane =(JScrollPane)jTabbedPane.getSelectedComponent();

And then get the selected component of that (which would be the text panel):

SQL

JTextPane jtextpanel=(JTextPane)jscrollpane.getSelectedComponent();

You should do some type checking though to be safe. Also, you could create a recursive method using getComponents to find the desired text panel on the tab or scroll panel.

Good luck!

Can you use the JScrollPane's getComponent(int) method to get the JTextPane? I'd presume that if the JTextPane is the only component in the scroll pane, passing 0 to getComponent(int) would give you the JTextPane.

Dear Marc A. Brown,

I had 3 components in my ScrollPane. As you mentioned, I have used jScrollPane.getComponent(0);, it returns a JViewPort, since I have used setViewPortView(JtextPane);

I used this code snippet and my problem get solved:

JScrollPane jscrollpane =(JScrollPane)jTabbedPane1.getSelectedComponent();
JViewport viewPort = (JViewport) jscrollpane.getComponent(0);
JTextPane jTextPane = (JTextPane)viewPort.getComponent(0);

Thanks a lot.....
