Could be Text orientation of JTextArea changed by

问题:

A JTextArea has componenent orientation set to LEFT, so text is written from left to right. Sometimes, it happens that while the user is writing, the text orientation suddenly changes to right, so all the text appears aligned to right. I can't explain why this happens (I have no direct feedback by users), but I guess that, while the user is typing, he activates some keyboard shortcut which changes the text orientation. Does someone know how this can happen? Can be there something else which triggers the change of text orientation in a text area?

Swing has predefined keyboard shortcuts which activates within the creation of swing objects. You should edit your key bindings. This article is useful for your situation.
