public class Stack

extends NodePanel

pop

getState(String)

This method is invoked in order to get the state of Stack for export.

move(EditorObject, int, int)

This is the special move method for Stack and is invoked by AnimImpl in order to handle all the movements one stack movement needs to do.

paint(Graphics)

This method is invoked when this panel is draw into the screen.

pop()

This method is invoked when the pop-button is pushed.

setFont(Font)

This method should be overridden in order to invoke setFont for every subComponent

  protected Button pop

  public final void setFont(Font font)

This method should be overridden in order to invoke setFont for every subComponent

Overrides:

setFont in class EditorObject

  public void pop()

This method is invoked when the pop-button is pushed. A new slot (with stack pile) is created.

  public void move(EditorObject object,
                   int x,
                   int y)

This is the special move method for Stack and is invoked by AnimImpl in order to handle all the movements one stack movement needs to do. There could be several move operations (many items could be moved) in one stack move operation. The pop-method marks the beginning and end of the pop operation and when a backward/forward button in pressed we have to make all the move operations between those states as a one move operation. To make this method compatible with all the other move methods, the animImpl class delivers also parameters which are ignored.

Parameters:

object - move backward if object is null, move forward if not. (this is the way pop-method marks the beginning/end)

x - not needed

y - not needed

Overrides:

move in class EditorObject

  protected String getState(String str)

This method is invoked in order to get the state of Stack for export.

Parameters:

str - is the substitute string for empty slot.

Returns:

the current state (string of items in the slots) of this stack.

Overrides:

getState in class EditorPanel

export

  public boolean paint(Graphics g)

This method is invoked when this panel is draw into the screen.

Overrides:

paint in class NodePanel
