public class JEditTextArea extends javax.swing.JComponent
jEdit's text area component. It is more suited for editing program source code than JEditorPane, because it drops the unnecessary features (images, variable-width lines, and so on) and adds a whole bunch of useful goodies such as:
JEditTextArea ta = new JEditTextArea(); ta.setTokenMarker( new JavaTokenMarker() ); ta.setText( "public class Test {\n" + " public static void main(String[] args) {\n" + " System.out.println(\"Hello World\");\n" + " }\n" + "}" );

start
- The start offsetlen
- The length of the substringCopies the specified substring of the document into a segment. If the offsets are invalid, the segment will contain a null string.

- The segment Returns the document's token marker. Equivalent to calling
getDocument().getTokenMarker()
.
Returns the number of lines visible in this text area.
Returns true if the caret is blinking, false otherwise.
Returns true if the caret is visible, false otherwise.
Returns true if this text area is editable, false otherwise.
Returns if this component can be traversed by pressing the Tab key. This returns false.
Returns true if overwrite mode is enabled, false otherwise.
Returns true if the selection is rectangular, false otherwise.
Converts a line index to a y co-ordinate.
line
- The lineConverts an offset in a line into an x co-ordinate. This is a slow version that can be used any time.
line
- The lineoffset
- The offset, from the start of the line Similar to setSelectedText()
, but overstrikes the appropriate
number of characters if overwrite mode is enabled.
str
- The stringInserts the clipboard contents into the text.
Forwards key events directly to the input handler. This is slightly faster than using a KeyListener because some Swing overhead is avoided.
Recalculates the number of visible lines. This should not be called directly.
Removes a caret change listener from this text area.
listener
- The listenerCalled by the AWT when this component is removed from it's parent. This stops clears the currently focused component.
Ensures that the specified line and offset is visible by scrolling the text area if necessary.
line
- The line to scroll tooffset
- The offset in the line to scroll toEnsures that the caret is visible by scrolling the text area if necessary.
Selects from the start offset to the end offset. This is the general selection method used by all other selecting methods. The caret position will be start if start < end, and end if end > start.
start
- The start offsetend
- The end offsetSelects all text in the document.
Moves the mark to the caret position.
Toggles caret blinking.
caretBlinks
- True if the caret should blink, false otherwiseSets the caret position. The new selection will consist of the caret position only (hence no text will be selected)
caret
- The caret positionSets if the caret should be visible.
caretVisible
- True if the caret should be visible, false otherwiseSets the document this text area is editing.
document
- The documentSets if this component is editable.
editable
- True if this text area should be editable, false otherwiseSets the line displayed at the text area's origin without updating the scroll bars.
Sets the input handler.
inputHandler
- The new input handlerSets the `magic' caret position. This can be used to preserve the column position when moving up and down lines.
magicCaret
- The magic caret positionSets if overwrite mode should be enabled.
overwrite
- True if overwrite mode should be enabled, false otherwise.Sets the right click popup menu.
popup
- The popupReplaces the selection with the specified text.
selectedText
- The replacement text for the selectionSets the selection end. The new selection will be the old selection start and the bew selection end.
selectionEnd
- The selection endSets if the selection should be rectangular.
overwrite
- True if the selection should be rectangular, false otherwise.Sets the selection start. The new selection will be the new selection start and the old selection end.
selectionStart
- The selection startSets the entire text of this text area.
Sets the document's token marker. Equivalent to caling
getDocument().setTokenMarker()
.
tokenMarker
- The token markerUpdates the state of the scroll bars. This should be called if the number of lines in the document changes, or when the size of the text area changes.
Converts an x co-ordinate to an offset within a line.
line
- The linex
- The x co-ordinateConverts a point to an offset, from the start of the text.
x
- The x co-ordinate of the pointy
- The y co-ordinate of the pointConverts a y co-ordinate to a line index.
y
- The y co-ordinate
