public DefaultPopupFactory.PanelPopup()

Method Detail

processKeyEvent

protected void processKeyEvent(KeyEvent e)

Description copied from class: Component

Processes key events occurring on this component by dispatching them to any registered KeyListener objects.

This method is not called unless key events are enabled for this component. Key events are enabled when one of the following occurs:

• A KeyListener object is registered via addKeyListener.
• Key events are enabled via enableEvents.

Overrides:

processKeyEvent in class Component

Following copied from class: java.awt.Component

Parameters:

e - the key event.

See Also:

KeyEvent, KeyListener, Component.addKeyListener(java.awt.event.KeyListener), Component.enableEvents(long)

getWidth

public int getWidth()

Description copied from class: Component

Return the current width of this component. This method is preferable to writing component.getBounds().width, or component.getSize().width because it doesn't cause any heap allocations.

Specified by:

getWidth in interface Popup

Overrides:

getWidth in class Component

Following copied from class: java.awt.Component

Returns:

the current width of this component.

getHeight

public int getHeight()

Description copied from class: Component

Return the current height of this component. This method is preferable to writing component.getBounds().height, or component.getSize().height because it doesn't cause any heap allocations.

Specified by:

getHeight in interface Popup

Overrides:

getHeight in class Component

Following copied from class: java.awt.Component

Returns:

the current height of this component.

getComponent

public Component getComponent()

addComponent

public void addComponent(Component aComponent,
                         Object constraints)

Specified by:

addComponent in interface Popup

removeComponent

public void removeComponent(Component c)

Specified by:

removeComponent in interface Popup

update

public void update(Graphics g)

Description copied from class: Container

Updates the container. This forwards the update to any lightweight components that are children of this container. If this method is reimplemented, super.update(g) should be called so that lightweight components are properly rendered. If a child component is entirely clipped by the current clipping setting in g, update() will not be forwarded to that child.

Overrides:

update in class Container

Following copied from class: java.awt.Container

Parameters:

g - the specified Graphics window

See Also:

Component.update(java.awt.Graphics)

paint

public void paint(Graphics g)

Description copied from class: Container

Paints the container. This forwards the paint to any lightweight components that are children of this container. If this method is reimplemented, super.paint(g) should be called so that lightweight components are properly rendered. If a child component is entirely clipped by the current clipping setting in g, paint() will not be forwarded to that child.

Overrides:

paint in class Container

Following copied from class: java.awt.Container

Parameters:

g - the specified Graphics window

See Also:

Component.update(java.awt.Graphics)

pack

public void pack()

Specified by:

pack in interface Popup

show

public void show(Component invoker)

Specified by:

show in interface Popup

hide

public void hide()

Specified by:

hide in interface Popup

Overrides:

hide in class Component

getBoundsOnScreen

public Rectangle getBoundsOnScreen()

Specified by:

getBoundsOnScreen in interface Popup

setLocationOnScreen

public void setLocationOnScreen(int x,
                                int y)

Specified by:

setLocationOnScreen in interface Popup
