My JPanel contains a JEditorPane. I use the JEditorPane as output.
The text of JEditorPane is changed very frequently and sometimes the text is large (more than 5000 lines).
To show text I am using SwingUtilities.invokeLater(Runnable run)
If the contentType of JEditorPane is "text/plain" the text loads faster than "text/html".
Can I insert first the text into the JEditorPane as plain text and then change the contentType?
You have got the wrong sort of thing in the run() method. You only need to create the GUI in that method; then don’t start any new threads which affect Swing objects.This assumes that all code required to display the GUI can be accessed (albeit indirectly) from the MyGui() constructor.
I had to edit this post twice because I noticed mistakes in it.
The event dispatch thread, where all event-handling code is executed. Most code that interacts with the Swing framework must also execute on this thread.
Worker threads, also known as background threads, where time-consuming background tasks are executed.
I am novice and I want you to correct my thinking. So all GUIs update must be done from EDT. That's why I use SwingUtilities.
I dont use SwingWorker because SwingWorker must be used for background long-running tasks.
Here is a SSCCE example. I read a large text file and I show it in a JEditorPane.
How can I increase the speed of insertion in a JEditorPane?
