Method Detail

setTreePane

void setTreePane(TreePane treePane)

Called when the painter is installed in a TreePane. Gives the painter a handle on the TreePane so that it get additional information.

Parameters:

treePane -

isVisible

boolean isVisible()

If this is false then the painter should not be displayed.

Returns:

is visible?

calibrate

Rectangle2D calibrate(Graphics2D g2,
                      T item)

Called to calibrate the painters for a given graphics context. This should work out the preferred width and height (perhaps for the current font).

Parameters:

g2 -

item -

paint

void paint(Graphics2D g2,
           T item,
           Painter.Justification justification,
           Rectangle2D bounds)

Called to actually paint into the current graphics context. The painter should respect the bounds.

Parameters:

g2 -

item -

justification -

bounds -

getPreferredWidth

double getPreferredWidth()

getPreferredHeight

double getPreferredHeight()

getHeightBound

double getHeightBound()

addPainterListener

void addPainterListener(PainterListener listener)

removePainterListener

void removePainterListener(PainterListener listener)
