No problem. Since there are legitimate uses for it, I went ahead and made setDirty() public, but modified its doc comment to explain that most applications won't have to call it directly.

And thanks

That was excactly why I needed it. I'm getting the source code I will be editing in a list of a custom object type. It's actually pretty inefficient in my case to get each piece of code separately.

I didn't quite understand FileLocation so I was creating the TextEditorPane empty and using setText() to set the editor text.

I have since then realized that using FileLocation was the only way to get it to work so I monkeyed around with that and have mostly figured it out. I have a separate forum thread for an issue that I'm running in to when a save fails.

This functionality would have let me do it without FileLocation.

The method will be public in SVN later today, and in the next release. I'm including information in the doc comment stating that the programmer usually doesn't need to call the method directly. The only time I can imagine you'd need to do so is if you needed to initialize a TextEditorPane with content that did not come from a file or URL.

How do I open an enhancement request to have isDirty(boolean) created so that I can do isDirty(false) the way you describe above? I would love that functionality.

Oops, didn't realize that was a private method. I guess my thinking was that the editor should always know when it was dirty and when it wasn't.

That was the reason. I solved it by using load(), thanks for the help :)

[quote="robert"]...just call setDirty(false) after your initialization...[/quote]
The visibility of the setDirty() method in TextEditorPane is set to private... Maybe, this is a bug? Am i misunderstanding you?

So, i have another question: When i check with isDirty() i get true, even if hadn't done any changes. Why that?

It shouldn't be. How did you load the initial text? If you used TextEditorPane.load(), the dirty flag should not be set. Obviously, calling something like setText() to put the initial text in will set the dirty flag to true. So will calling setEncoding() - TextEditorPane considers an encoding change to be an important change. My guess is you're doing one of those two things. If you are, and you have to do them, just call setDirty(false) after your initialization and you should be fine.

Hi,

i am using TextEditorPane inside RTextScrollPane. So how can i access the TextEditorPane inside the RTextScrollpane, which is stored in a tab of JTabbedPane?

[b]Update:[/b]
Found it, just:
[code]
RTextScrollPane sp = (RTextScrollPane)jTabbedPane.getComponentAt(i);
JOptionPane.showConfirmDialog(null, sp.getTextArea().getClass().getName());
[/code]
Example:
[code]((TextEditorPane)sp.getTextArea()).isDirty()[/code]

So, i have another question: When i check with isDirty() i get true, even if hadn't done any changes. Why that?

Hi Golana,

The easiest way to do this is to add a javax.swing.event.DocumentListener to the editor's Document, and add the "*" to the displayed file name when the document is modified. Remove it whenever it is saved.

You can also use the org.fife.ui.rsyntaxtextarea.[url=http://javadoc.fifesoft.com/rsyntaxtextarea/org/fife/ui/rsyntaxtextarea/TextEditorPane.html]TextEditorPane[/url] class, that comes standard in the library. It has a "dirty" flag that is set/cleared properly when you edit/save/reload the file. You can also query it directly via the isDirty() method. Note that you'll still have to add the DocumentListener though to know when it's first made dirty.

From its documentation:

[quote]
An extension of RSyntaxTextArea that adds information about the file being edited, such as:

Its name and location.
Is it dirty?
Is it read-only?
The last time it was loaded or saved to disk (local files only).
The file's encoding on disk.
Easy access to the line separator.

Loading and saving is also built into the editor.

Both local and remote files (e.g. ftp) are supported. See the FileLocation class for more information.
