public class DrawableX_Node

extends DrawableSGMLNode

Author:

(C) P. Murray-Rust, 1996

DrawableX_Node(SGMLTree)

some nodes will not have GIs - they are given a GI of "UNKNOWN"

DrawableX_Node(String, SGMLTree)

action(Event, Object)

pass any button actions to the object

addTitle(String)

replaces current title with title and adds TITLE Attribute

debug()

for debug

display(Graphics)

used by the ScrollableTopLevel to paint the object, or can be used to draw the object to somewhere else.

display(Graphics, Component)

this is the primary mechanism for calling the display and the component can be captured here.

display(Int2Range)

alternative display routine when we know the target screen area for the object

display(IntSet)

display the subaddresses in the node; we might need to alter the hierarchy to cater for this...

drawIcon(Graphics, int, int)

draw a CML icon

generalDisplay(Graphics)

generic display unrelated to object details.

getFont()

get the font for this node

getName()

get the node name (e.g.

getTitle()

get title from TITLE, DICTNAME, BUILTIN if present, else TITLE

highlight(IntSet)

highlight any subAddresses in Node - default is no action unless overridden

mayContain(SGMLNode)

can this node contain others.

mouseDown(Event, int, int)

action when mouse is clicked; if not overridden, no action

mouseDrag(Event, int, int)

action when mouse is dragged; if not overridden, no action

mouseUp(Event, int, int)

action when mouse is unclicked; if not overridden, no action

processMouseBox(Int2Range)

action when mouseBox has been swept out; if not overridden, tries to scale the object.

receiveEvent(Object, int)

act on a register callback (CRUDE); gets a simple message (an item number) from a sending object

repaint()

repaint the component (the best we can do)

setFont(Font)

set the font for this node

showHelp()

a help file for the Node.

  public DrawableX_Node(SGMLTree tree)

some nodes will not have GIs - they are given a GI of "UNKNOWN"

  public DrawableX_Node(String giName,
                        SGMLTree tree)

  public String getTitle()

get title from TITLE, DICTNAME, BUILTIN if present, else TITLE

Overrides:

getTitle in class SGMLNode

  public void addTitle(String title)

replaces current title with title and adds TITLE Attribute

  public boolean mayContain(SGMLNode n)

can this node contain others. (Full DTD parsing is not enabled, so order and count are not used at present. Subclasses should override this where they can prove that something canNOT be conatined by this node

Overrides:

mayContain in class SGMLNode

  public String getName()

get the node name (e.g. required for a FullAddress). If the name is not given, returns a string of form NODE123

  public int drawIcon(Graphics g,
                      int x,
                      int y)

draw a CML icon

Overrides:

drawIcon in class SGMLNode

  public void showHelp()

a help file for the Node. Usually subclassed

Overrides:

showHelp in class DrawableSGMLNode

  public void receiveEvent(Object sender,
                           int item)

act on a register callback (CRUDE); gets a simple message (an item number) from a sending object

  public void display(Int2Range screenLimits)

alternative display routine when we know the target screen area for the object

  public void display(Graphics g,
                      Component comp)

this is the primary mechanism for calling the display and the component can be captured here. It's called from the paint(g) routine, so may be used for double buffering, etc. VERY experimental

Overrides:

display in class DrawableSGMLNode

  public void display(Graphics g)

used by the ScrollableTopLevel to paint the object, or can be used to draw the object to somewhere else. By using the Scaler2D approach it is possible to draw the object to any desired screen location. Normally overriden.

Overrides:

display in class DrawableSGMLNode

  public void generalDisplay(Graphics g)

generic display unrelated to object details. Must be called from the end display(g); EXPERIMENTAL - to test clipboard cut/paste approach

  public void display(IntSet subAddress)

display the subaddresses in the node; we might need to alter the hierarchy to cater for this...

  public void setFont(Font f)

set the font for this node

  public Font getFont()

get the font for this node

  public void highlight(IntSet is)

highlight any subAddresses in Node - default is no action unless overridden

  public boolean mouseUp(Event evt,
                         int x,
                         int y)

action when mouse is unclicked; if not overridden, no action

Overrides:

mouseUp in class DrawableSGMLNode

  public boolean mouseDown(Event evt,
                           int x,
                           int y)

action when mouse is clicked; if not overridden, no action

Overrides:

mouseDown in class DrawableSGMLNode

  public boolean mouseDrag(Event evt,
                           int x,
                           int y)

action when mouse is dragged; if not overridden, no action

Overrides:

mouseDrag in class DrawableSGMLNode

  public boolean processMouseBox(Int2Range box)

action when mouseBox has been swept out; if not overridden, tries to scale the object. To disable this, override this method with 'return true'

Overrides:

processMouseBox in class DrawableSGMLNode

  public boolean action(Event e,
                        Object arg)

pass any button actions to the object

Overrides:

action in class DrawableSGMLNode

  public void repaint()

repaint the component (the best we can do)

  public void debug()

for debug

Overrides:

debug in class DrawableSGMLNode
