java.lang.Object java.awt.Component java.awt.Container javax.swing.JComponent org.fife.ui.rsyntaxtextarea.ErrorStrip
public class ErrorStrip
A component to sit alongside an RSyntaxTextArea
that displays
colored markers for locations of interest (parser errors, marked
occurrences, etc.).
ErrorStrip
s display ParserNotice
s from
Parser
s. Currently, the only way to get lines flagged in this
component is to register a Parser
on an RSyntaxTextArea and
return ParserNotice
s for each line to display an icon for.
The severity of each notice must be at least the threshold set by
setLevelThreshold(int)
to be displayed in this error strip. The
default threshold is ParserNotice.WARNING
.
An ErrorStrip
can be added to a UI like so:
textArea = createTextArea(); textArea.addParser(new MyParser(textArea)); // Identifies lines to display scrollPane = new RTextScrollPane(textArea, true); ErrorStrip es = new ErrorStrip(textArea); JPanel temp = new JPanel(new BorderLayout()); temp.add(scrollPane); temp.add(es, BorderLayout.LINE_END);

ErrorStrip(RSyntaxTextArea textArea)
Constructor. |
Method Summary | |
---|---|
void |
addNotify()
Overridden so we only start listening for parser notices when this component (and presumably the text area) are visible. |
void |
doLayout()
Manually manages layout since this component uses no layout manager. |
java.awt.Color |
getCaretMarkerColor()
returns the color to use when painting the caret marker. |
boolean |
getFollowCaret()
Returns whether the caret's position should be drawn. |
int |
getLevelThreshold()
Returns the minimum severity a parser notice must be for it to be displayed in this error strip. |
java.awt.Dimension |
getPreferredSize()
|
boolean |
getShowMarkAll()
Returns whether "mark all" highlights are shown in this error strip. |
boolean |
getShowMarkedOccurrences()
Returns whether marked occurrences are shown in this error strip. |
java.lang.String |
getToolTipText(java.awt.event.MouseEvent e)
|
protected void |
paintComponent(java.awt.Graphics g)
Overridden to (possibly) draw the caret's position. |
void |
removeNotify()
|
void |
setCaretMarkerColor(java.awt.Color color)
Sets the color to use when painting the caret marker. |
void |
setFollowCaret(boolean follow)
Toggles whether the caret's current location should be drawn. |
void |
setLevelThreshold(int level)
Sets the minimum severity a parser notice must be for it to be displayed in this error strip. |
void |
setShowMarkAll(boolean show)
Sets whether "mark all" highlights are shown in this error strip. |
void |
setShowMarkedOccurrences(boolean show)
Sets whether marked occurrences are shown in this error strip. |
