dim

If not 0, then this is the minimum dimension.

height

mapped

True when the object is mapped.

marginHeight

marginWidth

name

The symbolic name of the object.

parent

The parent of the object, this may be 0 for windows.

tidy

True when the object is tidy (layed out).

width

x

The dimensions of the object.

y

getChild(String)

Returns child by name, only valid for containers.

getPreferredSize()

Returns the natural size of the object.

handleEvent(Event)

Handle Events

layout()

Calls layout() on the component (most commonly used by container objects).

map()

Maps the object (called automatically when the parent is mapped).

minDimension()

Returns the minimum size of the object.

move(int, int)

Moves the component to a new location.

postEvent(Event)

Posting Events

reshape(int, int, int, int)

Reshapes the component.

resize(int, int)

Changes the size of the component.

setDimension(Dimension)

Sets the dimension of the component.

setDimension(int, int)

Sets the dimension of the component.

setForeground(Color)

Sets the foreground color of this component (if applicable).

unMap()

UnMaps the object (called automatically when the parent is unmapped).

  public Container parent

The parent of the object, this may be 0 for windows.

  public String name

The symbolic name of the object. Often used for layout.

  public int x

The dimensions of the object.

  public int y

  public int width

  public int height

  public int marginHeight

  public int marginWidth

  public boolean mapped

True when the object is mapped.

  protected boolean tidy

True when the object is tidy (layed out).

  protected Dimension dim

If not 0, then this is the minimum dimension.

  public void map()

Maps the object (called automatically when the parent is mapped). This has no effect if the parent is not mapped.

unMap

  public void unMap()

UnMaps the object (called automatically when the parent is unmapped).

reshape

  public void reshape(int pX,
                      int pY,
                      int pW,
                      int pH)

Reshapes the component. Leaves the object untidy. This means that Layout must be called to tidy it up.

move

  public void move(int pX,
                   int pY)

Moves the component to a new location.

resize

  public void resize(int pW,
                     int pH)

Changes the size of the component.

layout

  public void layout()

Calls layout() on the component (most commonly used by container objects).

getPreferredSize

  public Dimension getPreferredSize()

Returns the natural size of the object.

getChild

  public Layoutable getChild(String name)

Returns child by name, only valid for containers. Override if needed.

minDimension

  public Dimension minDimension()

Returns the minimum size of the object.

setDimension

  public void setDimension(Dimension d)

Sets the dimension of the component.

setForeground

  public void setForeground(Color c)

Sets the foreground color of this component (if applicable).

setDimension

  public void setDimension(int pW,
                           int pH)

Sets the dimension of the component.

postEvent

  public boolean postEvent(Event e)

Posting Events

handleEvent

  public boolean handleEvent(Event e)

Handle Events
