possiblyUpdateCurrentLineHighlightLocation()
Updates the current line highlight location.
|

processComponentEvent(java.awt.event.ComponentEvent e)
Overridden so we can tell when the text area is resized and update the
current-line highlight, if necessary (i.e., if it is enabled and if
lineWrap is enabled.

void |
setTabsEmulated(boolean areEmulated)
Changes whether or not tabs should be emulated with spaces (i.e., soft
tabs).
|
void |
setTabSize(int size)
Workaround, since in JDK1.4 it appears that
setTabSize()
doesn't work for a JTextArea unless you use the constructor
specifying the number of rows and columns... |
protected void |
updateMarginLineX()
This is here so subclasses such as
RSyntaxTextArea that
have multiple fonts can define exactly what it means, for example, for
the margin line to be "80 characters" over. |

NOTE: the opaque property is set to true when the
background is set to a color (by this method). When an image is used
for the background, opaque is set to false. This is because
we perform better when setOpaque is true, but if we use an
image for the background when opaque is true, we get on-screen
garbage when the user scrolls via the arrow keys. Thus we
need setOpaque to be false in that case.You never have to change the opaque property yourself; it is always done for you.
