Constructor Detail

BScrollPane.BViewport

public BScrollPane.BViewport(BComponent target,
                             boolean vert,
                             boolean horiz,
                             int snap)

Method Detail

getTarget

public BComponent getTarget()

Returns a reference to the target of this viewport.

getVModel

public BoundedRangeModel getVModel()

Returns the range model defined by this viewport's size and the preferred size of its target component.

getHModel

public BoundedRangeModel getHModel()

Returns the range model defined by this viewport's size and the preferred size of its target component.

invalidate

public void invalidate()

Description copied from class: BComponent

Marks this component as invalid and needing a relayout. If the component is valid, its parent will also be marked as invalid.

Overrides:

invalidate in class BComponent

layout

public void layout()

Description copied from class: BComponent

Instructs this component to lay itself out. This is called as a result of the component changing size.

Overrides:

layout in class BContainer

getAbsoluteX

public int getAbsoluteX()

Description copied from class: BComponent

Returns the x position of this component in absolute screen coordinates.

Overrides:

getAbsoluteX in class BComponent

getAbsoluteY

public int getAbsoluteY()

Description copied from class: BComponent

Returns the y position of this component in absolute screen coordinates.

Overrides:

getAbsoluteY in class BComponent

getHitComponent

public BComponent getHitComponent(int mx,
                                  int my)

Description copied from class: BComponent

Returns the component "hit" by the specified mouse coordinates which might be this component or any of its children. This method should return null if the supplied mouse coordinates are outside the bounds of this component.

Overrides:

getHitComponent in class BContainer

wasAdded

protected void wasAdded()

Description copied from class: BComponent

This method is called when we are added to a hierarchy that is connected to a top-level window (at which point we can rely on having a look and feel and can set ourselves up).

Overrides:

wasAdded in class BContainer

wasRemoved

protected void wasRemoved()

Description copied from class: BComponent

This method is called when we are removed from a hierarchy that is connected to a top-level window. If we wish to clean up after things done in BComponent.wasAdded(), this is a fine place to do so.

Overrides:

wasRemoved in class BContainer

computePreferredSize

protected Dimension computePreferredSize(int whint,
                                         int hhint)

Description copied from class: BComponent

Computes and returns a preferred size for this component. This method is called if no overriding preferred size has been supplied.

Overrides:

computePreferredSize in class BContainer

Returns:

the computed preferred size of this component in a newly created Dimension instance which will be adopted (and modified) by the caller.

renderComponent

protected void renderComponent(Renderer renderer)

Description copied from class: BComponent

Renders any custom bits for this component. This is called with the graphics context translated to (0, 0) relative to this component.

Overrides:

renderComponent in class BContainer

getYOffset

protected final int getYOffset()

getXOffset

protected final int getXOffset()
