Constructor Details

WrapperContainer

public WrapperContainer(Container c)

Method Details

scrollRectToVisible

public void scrollRectToVisible(Rectangle aRect)

Overridden to not have JViewPort behaviour (that is scroll the view) but delegate to parent scrollRectToVisible just a JComponent does.

Overrides:

scrollRectToVisible in class JViewport

getAlpha

public float getAlpha()

Description copied from interface: AlphaPaintable

Get the current alpha value.

Specified by:

getAlpha in interface AlphaPaintable

Returns:

the alpha translucency level for this component. This will be a value between 0 and 1, inclusive.

setAlpha

public void setAlpha(float alpha)

Description copied from interface: AlphaPaintable

Set the alpha transparency level for this component. This automatically causes a repaint of the component.

Specified by:

setAlpha in interface AlphaPaintable

Parameters:

alpha - must be a value between 0 and 1 inclusive

isInheritAlpha

public boolean isInheritAlpha()

Description copied from interface: AlphaPaintable

Returns the state of the panel with respect to inheriting alpha values.

Specified by:

isInheritAlpha in interface AlphaPaintable

Returns:

true if this panel inherits alpha values; false otherwise

See Also:

• AlphaPaintable.setInheritAlpha(boolean)

setInheritAlpha

public void setInheritAlpha(boolean inheritAlpha)

Description copied from interface: AlphaPaintable

Determines if the effective alpha of this component should include the alpha of ancestors.

Specified by:

setInheritAlpha in interface AlphaPaintable

Parameters:

inheritAlpha - true to include ancestral alpha data; false otherwise

See Also:

• AlphaPaintable.isInheritAlpha()
• AlphaPaintable.getEffectiveAlpha()

getEffectiveAlpha

public float getEffectiveAlpha()

Description copied from interface: AlphaPaintable

Unlike other properties, alpha can be set on a component, or on one of its parents. If the alpha of a parent component is .4, and the alpha on this component is .5, effectively the alpha for this component is .4 because the lowest alpha in the hierarchy "wins."

Specified by:

getEffectiveAlpha in interface AlphaPaintable

Returns:

the lowest alpha value in the hierarchy

isPaintingOrigin

protected boolean isPaintingOrigin()

Overrides:

isPaintingOrigin in class JViewport

paint

public void paint(Graphics g)

Overridden paint method to take into account the alpha setting.

Overrides:

paint in class JViewport

Parameters:

g - the Graphics context in which to paint
