Getting text from inside a jeditorpane inside a jtabbedpane

[captain alge]

greetings,

I have a small program that contains a jTabbedPane. Then, when the user does an action (like click a button) a new jScrollPane is created, and a new jEditorPane is placed inside it. The jScrollPane is then added to the jTabbedPane.

The jEditorPane then fills itself with information from a different file, depending on which button was clicked.

All that works fine, but the problem arrises when I want to save the information to the file later. I can't get the text from inside the jEditorPane.

Here is the method which adds a new tab:

public void addTab()
{
    currentFile = "The File";
    //create new editor pane
    DefaultSyntaxKit.initKit(); //I'm using a custom kit
    JEditorPane editPane = new JEditorPane();
    JScrollPane editScroll = new JScrollPane(editPane);
    editPane.setContentType("text/java");
    editPane.setText("");
    editScroll.setViewportView(editPane);
    editPane.setName("the editor");
    editScroll.setName("the scroll");
    try
    {
        FileReader input = new FileReader(new File("The directory" + currentFile));
        myTabbedPane.addTab(currentFile, editScroll);
        editPane.read(input, null);
        input.close();
    }
    catch (IOException e)
    {
        e.printStackTrace();
    }
}

I can't show you the save code because I really haven't got any. I know I can get the current selected component/tab from the jTabbedPane:

myTabbedPane.getSelectedComponent();

But that has two problems:
1) It actually returns the scrollPane, not the editor
2) It returns a component , component has no getText() method

Any one got any ideas? I'm all out

cheers!

really? no one?

I'm amazed by your monk-like patience. 1 Hour and 11 Minutes is almost a lifetime to wait.

No, no its alright. I'll take time out of my busy schedule to help you. Its the least I can do for you your majesty.

[captain alge]

and that was helpful how?

Sorry if I do seem impatient, but after three days straight of working on the same problem I think It's probably forgiveable

And if your schedule is so busy, I fail to understand how you manage to have time to post comments like that

But that has two problems:
1) It actually returns the scrollPane, not the editor
2) It returns a component , component has no getText() method

1) True, because that was the component that was added to your JTabbedPane; note that your editor is a child component of that JScrollPane.

2) casts? A JTabbedPane is only interested in JComponents being added to its tabs, it doesn't care what component it actually is.

kind regards,

Jos

Rudeness is hardly forgiveable, if you had the same problem for three straight days why didn't you ask for help sooner?

Either way JosAH is a much nicer individual than I, so you lucked out.

[captain alge]

Because I was trying to sort it out myself, normally that's easier than coming on here

Fortunately you're right, so cheers JosAH :)

lesson(hopefully) learned: Don't bump your thread so hastily. People that are currently on may not have a good enough answer for you. Bumping the thread in such a short amount of time only makes people less likely to respond. Wait a few hours, see if anyone posts anything, then perhaps you can bump.

Who knows when someone with the answer will check the forums? I understand how frustrating it is to be stuck on something and desperate for some help, unfortunately you have to be patient.

Right, got it!

Cheers JosAH for working this one out, here is the full code:

Code which adds editor to tabbedpane

String currentFile = new File("the directory" + "the file");
//create new syntax pane
DefaultSyntaxKit.initKit(); //I'm using a custom kit
JEditorPane editPane = new JEditorPane();
JScrollPane editScroll = new JScrollPane(editPane);
editPane.setContentType("text/java");
editScroll.setViewportView(editPane);
editPane.setName(currentFile);
try
{    
    FileReader input = new FileReader(currentFile);
    myTabbedPane.addTab(currentFile, editScroll);
    editPane.read(input, this);
    input.close();
}
catch (IOException e)
{
    e.printStackTrace();
}

Code which saves to file:

JScrollPane scroll= (JScrollPane)myTabbedPane.getComponentAt(index);
JViewport view = (JViewport)scroll.getViewport();
JEditorPane editor = (JEditorPane)view.getComponent(0);
try
{
    FileWriter fw = new FileWriter(currentFile);
    editor.write(fw);
    fw.close();
}
catch (IOException e)
{
    e.printStackTrace;
}

Hope this can help someone else

Hope this can help someone else

Glad you've solved it; I like it when someone comes back here to show the solution to the problem; and, as always, monetary tokens of gratitude should be sent directly to me; ignore that Darryl Burke phisher ;-)

kind regards,

Jos
