Re: [ jEdit-devel ] jEdit.openFile?

[Slava P. <sp...@gj...>]

Dan,

First of all, don't call openFile() (or most other jEdit APIs, for that
matter) from any thread except for the event dispatch thread.

Keep in mind that the actual file loading is done in background thread
(or threads, in the case of jEdit 2.6) so stuff like:

buffer = jEdit.openFile(...)
buffer.getText(...)

will fail, because the buffer won't be loaded yet. To wait until the
buffer is loaded, you have three choices:

- call the static VFSManager.waitForRequests() method. Doing this is
  HIGHLY DISCOURAGED because it blocks the AWT thread and as a result
  the user will not be able to abort the I/O request if it hangs (this
  can happen when dealing with slow FTP servers, for example)

- wait for the BufferUpdate.LOADED message on the EditBus.

- call the static VFSManager.runInAWTThread(Runnable r) method. The
  specified runnable will be run in the AWT thread once all pending
  I/O is complete.

I hope this helps,

Slava
