Question

I’m trying to improve an existing implementation of document displaying component. One of the concerns expressed, that when loading a large bulk of text we will get an OOM exception.

From my previous experience with .net I do know that some base component implement paging, hence no all the text is visual loaded into the document hence things not only work faster but we will also, hopefully, avoid an OOM exception.

So I was wondering are there any base swing components, specifically JTextPanel, which support these capabilities?

Thank you for your help it is greatly appreciated

Answer 1

No, The JTextPane does not support memory pages. You can create a Docuemnt instance and read the file content into the Document without installing the Document in the JTextPane.
Then get desired fragment of the Document and insert it into another one showing the desired fragment only.
