LineNumberList(RTextArea textArea)
Constructs a new
LineNumberList using default values for
line number color (gray) and highlighting the current line. |
LineNumberList(RTextArea textArea,
java.awt.Color numberColor)
Constructs a new
LineNumberList. |
| Modifier and Type | Method and Description |
|---|---|
void |
addNotify()
Overridden to set width of this component correctly when we are first
displayed (as keying off of the RTextArea gives us (0,0) when it isn't
yet displayed.
|
protected static java.awt.Rectangle |
getChildViewBounds(javax.swing.text.View parent,
int line,
java.awt.Rectangle editorRect)
Returns the bounds of a child view as a rectangle, since
Views tend to use Shape. |
protected Gutter |
getGutter()
Returns the parent
Gutter component. |
int |
getLineNumberingStartIndex()
Returns the starting line's line number.
|
java.awt.Dimension |
getPreferredSize() |
protected void |
init()
Called by the constructor before the text area is set.
|
void |
mouseClicked(java.awt.event.MouseEvent e) |
void |
mouseDragged(java.awt.event.MouseEvent e) |
void |
mouseEntered(java.awt.event.MouseEvent e) |
void |
mouseExited(java.awt.event.MouseEvent e) |
void |
mouseMoved(java.awt.event.MouseEvent e) |
void |
mousePressed(java.awt.event.MouseEvent e) |
void |
mouseReleased(java.awt.event.MouseEvent e) |
protected void |
paintComponent(java.awt.Graphics g)
Paints this component.
|
void |
removeNotify()
Called when this component is removed from the view hierarchy.
|
void |
setFont(java.awt.Font font)
Overridden to ensure line number cell sizes are updated with the
font size change.
|
void |
setLineNumberingStartIndex(int index)
Sets the starting line's line number.
|
void |
setTextArea(RTextArea textArea)
Sets the text area being displayed.
