ImageViewSkin

public ImageViewSkin()
Method Detail

install

public void install(Component component)
Description copied from interface: Skin
Associates a skin with a component.

Specified by:
install in interface Skin
Overrides:
install in class ComponentSkin
Parameters:
component - The component to which the skin is being attached.

uninstall

public void uninstall()
Description copied from interface: Skin
Dissociates a skin from a component.

Specified by:
uninstall in interface Skin
Overrides:
uninstall in class ComponentSkin

getPreferredWidth

public int getPreferredWidth(int height)
Description copied from interface: ConstrainedVisual
Returns the visual's preferred width given the provided height constraint.

Specified by:
getPreferredWidth in interface ConstrainedVisual
Parameters:
height - The height by which to constrain the preferred width, or -1 for no constraint.

getPreferredHeight

public int getPreferredHeight(int width)
Description copied from interface: ConstrainedVisual
Returns the visual's preferred height given the provided width constraint.

Specified by:
getPreferredHeight in interface ConstrainedVisual
Parameters:
width - The width by which to constrain the preferred height, or -1 for no constraint.

getPreferredSize

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

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.

Specified by:
layout in interface Skin

paint

public void paint(Graphics2D graphics)
Description copied from interface: Visual
Paints the visual.

Specified by:
paint in interface Visual
Parameters:

isFocusable

public boolean isFocusable()
Description copied from class: ComponentSkin
By default, components are focusable.

Specified by:

isOpaque

public boolean isOpaque()
An image view's background color dictates whether or not it's opaque. We can't rely on the opacity style because even if the skin's opacity is 1, the actual image itself may contain transparent or translucent pixels.

Overrides:
isOpaque in class ComponentSkin
Returns:
true if opacity is 1; false otherwise.
