public class BTextArea

extends JTextArea

Extends JTextArea and overrides the isManagingFocus() method so that it returns false. This means that Tab key events will result in the focus transferred, instead of inserting a tab into the text area.

Method Detail

isManagingFocus

public boolean isManagingFocus()

Overrides isManagingFocus() in JTextArea, so that it returns true instead of true.

Returns:

false, to indicate that this implementation of a text area does not manage the focus, and therefore, tab events will not be consumed in BTextArea.

Overrides:

isManagingFocus in class JTextArea
