Constructor Detail

FrequencyDragRenderer

public FrequencyDragRenderer(DasCanvasComponent parent,
                             DasAxis axis)

Creates a new instance of HorizontalFrequencyDragRenderer

Method Detail

renderDrag

public java.awt.Rectangle[] renderDrag(java.awt.Graphics g1,
                                       java.awt.Point p1,
                                       java.awt.Point p2)

Description copied from interface: DragRenderer

draws the drag for mousing from p1 to p2, and returns an array of Rectangles covering the rendering. If nothing is drawn, then an array of length zero should be returned, and nulls are allowed in the array. p1 and p2, and g are in the canvas frame of reference.

Specified by:

renderDrag in interface DragRenderer

Overrides:

renderDrag in class LabelDragRenderer

Parameters:

g1 - the graphics context for rendering

p1 - the click point

p2 - the current mouse position during drag and release.

Returns:

isPointSelection

public boolean isPointSelection()

Description copied from class: AbstractDragRenderer

indicates that MM.mousePointSelected() should called as new mouse events come in.

Specified by:

isPointSelection in interface DragRenderer

Overrides:

isPointSelection in class LabelDragRenderer

Returns:

true if the mouse module should receive events during the drag.

clear

public void clear(java.awt.Graphics g)

Description copied from class: AbstractDragRenderer

this is not used, and is left over from an old version of the library.

Specified by:

clear in interface DragRenderer

Overrides:

clear in class LabelDragRenderer

Parameters:

g - the graphics context

isUpdatingDragSelection

public boolean isUpdatingDragSelection()

Description copied from class: AbstractDragRenderer

range selection events should be fired during drag.

Specified by:

isUpdatingDragSelection in interface DragRenderer

Overrides:

isUpdatingDragSelection in class LabelDragRenderer

Returns:

true if selection events should be fired during drag.

getMouseDragEvent

public MouseDragEvent getMouseDragEvent(java.lang.Object source,
                                        java.awt.Point p1,
                                        java.awt.Point p2,
                                        boolean isModified)

Description copied from class: LabelDragRenderer

This method is called by the DMIA on mouse release. We use this to infer the mouse release and hide the Window. Note this assumes isUpdatingDragSelection is false! TODO: DMIA should call clear so this is more explicit.

Specified by:

getMouseDragEvent in interface DragRenderer

Overrides:

getMouseDragEvent in class LabelDragRenderer

p1 - the click point

p2 - the current mouse position during drag and release.

Returns:

the DragEvent

keyPressed

public void keyPressed(java.awt.event.KeyEvent e)

Specified by:

keyPressed in interface java.awt.event.KeyListener

keyReleased

public void keyReleased(java.awt.event.KeyEvent e)

Specified by:

keyReleased in interface java.awt.event.KeyListener

keyTyped

public void keyTyped(java.awt.event.KeyEvent e)

Specified by:

keyTyped in interface java.awt.event.KeyListener

addPropertyChangeListener

public void addPropertyChangeListener(java.lang.String p,
                                      java.beans.PropertyChangeListener l)

removePropertyChangeListener

public void removePropertyChangeListener(java.lang.String p,
                                         java.beans.PropertyChangeListener l)
