Method Detail

isFocusable

public boolean isFocusable()

Description copied from class: ComponentSkin

By default, skins are focusable.

Specified by:

isFocusable in interface Skin

Overrides:

isFocusable in class ComponentSkin

Returns:

true if this skin is focusable; false, otherwise.

getPreferredWidth

@UnsupportedOperation
public int getPreferredWidth(int height)

Description copied from interface: ConstrainedVisual

Returns the visual's preferred width given the provided height constraint.

Parameters:

height - The height by which to constrain the preferred width, or -1 for no constraint.

Returns:

The preferred width given the height constraint.

getPreferredHeight

@UnsupportedOperation
public int getPreferredHeight(int width)

Description copied from interface: ConstrainedVisual

Returns the visual's preferred height given the provided width constraint.

Parameters:

width - The width by which to constrain the preferred height, or -1 for no constraint.

Returns:

The preferred height given the width constraint.

getPreferredSize

@UnsupportedOperation
public Dimensions getPreferredSize()

Description copied from interface: ConstrainedVisual

Returns the visual's unconstrained preferred size.

Specified by:

getPreferredSize in interface ConstrainedVisual

Overrides:

getPreferredSize in class ComponentSkin

Returns:

The preferred size (width and height) of this component.

Depending on the component this can be a static value or derived (as for a container) from its subcomponents, etc.

The default implementation simply calls ConstrainedVisual.getPreferredWidth(int) and ConstrainedVisual.getPreferredHeight(int).

layout

public void layout()

Description copied from interface: Skin

If the component on which the skin is installed is a container, lays out the container's children.

paint

public void paint(java.awt.Graphics2D graphics)

Description copied from interface: Visual

Paints the visual.

Parameters:

graphics - The graphics context in which to paint the visual.

mouseOver

public void mouseOver(Component component)

Description copied from interface: ComponentMouseListener

Called when the mouse enters a component.

Default is to do nothing.

Specified by:

mouseOver in interface ComponentMouseListener

Overrides:

mouseOver in class ComponentSkin

Parameters:

component - Component that is now under the mouse pointer.

mouseOut

public void mouseOut(Component component)

Description copied from interface: ComponentMouseListener

Called when the mouse exits a component.

Default is to do nothing.

Specified by:

mouseOut in interface ComponentMouseListener

Overrides:

mouseOut in class ComponentSkin

Parameters:

component - Component that has now lost the mouse pointer.

mouseMove

public boolean mouseMove(Component component,
                         int x,
                         int y)

Description copied from interface: ComponentMouseListener

Called when the mouse is moved over a component.

Specified by:

mouseMove in interface ComponentMouseListener

Overrides:

mouseMove in class ComponentSkin

Parameters:

component - Component that is under the mouse.

x - X position of the mouse.

y - Y position of the mouse.

Returns:

true to consume the event; false to allow it to propagate (default return).

mouseDown

public boolean mouseDown(Component component,
                         Mouse.Button button,
                         int x,
                         int y)

Description copied from interface: ComponentMouseButtonListener

Called when a mouse button is pressed over a component.

Specified by:

mouseDown in interface ComponentMouseButtonListener

Overrides:

mouseDown in class ComponentSkin

Parameters:

component - Component that is under the mouse pointer.

button - Which mouse button was pressed.

x - X position of the mouse.

y - Y position of the mouse.

Returns:

true to consume the event; false to allow it to propagate (default).

mouseUp

public boolean mouseUp(Component component,
                       Mouse.Button button,
                       int x,
                       int y)

Description copied from interface: ComponentMouseButtonListener

Called when a mouse button is released over a component.

Specified by:

mouseUp in interface ComponentMouseButtonListener

Overrides:

mouseUp in class ComponentSkin

Parameters:

component - Component user the mouse pointer.

button - Which mouse button that was released.

x - X position of the mouse.

y - Y position of the mouse.

Returns:

true to consume the event; false to allow it to propagate (default).
