Constructor Detail

IlvScrollManagerView

public IlvScrollManagerView()

Creates a new IlvScrollManagerView. This method creates an IlvManager and a view of the manager by calling the createManagerView method.

IlvScrollManagerView

public IlvScrollManagerView(IlvManager manager,
                            IlvTransformer t)

Creates a new IlvScrollManagerView. This method creates an IlvManagerView that is added to the manager by calling the createManagerView method.

Parameters:

manager - the manager to scroll.

t - the initial transformer to draw the content of the manager. This is the initial transformer of the IlvManagerView that is created.

IlvScrollManagerView

public IlvScrollManagerView(IlvManager manager,
                            IlvTransformer t,
                            Adjustable verticalScrollbar,
                            Adjustable horizontalScrollbar)

Creates a new IlvScrollManagerView. This method creates an IlvManagerView that is added to the manager by calling the createManagerView method. This constructor also allows you to specify the scrollbars that you want.

Parameters:

manager - the manager to scroll.

t - the initial transformer to draw the content of the manager. This is the initial transformer of the IlvManagerView that is created.

verticalScrollbar - the vertical scrollbar. Note this must be a Component.

horizontalScrollbar - the horizontal scrollbar. Note this must be a Component.

See Also:

createManagerView(ilog.views.IlvManager, ilog.views.IlvTransformer)

IlvScrollManagerView

public IlvScrollManagerView(IlvManagerView view)

Creates a new IlvScrollManagerView.

Parameters:

view - the manager view that is scrolled.

IlvScrollManagerView

public IlvScrollManagerView(IlvManagerView view,
                            Adjustable verticalScrollbar,
                            Adjustable horizontalScrollbar)

Creates a new IlvScrollManagerView. This constructor also allows you to specify the scrollbars that you want. It may be, for example, instances of JFC's JScrollbar.

Parameters:

view - the manager view that is scrolled.

verticalScrollbar - the vertical scrollbar. Note this must be a Component.

horizontalScrollbar - the horizontal scrollbar. Note this must be a Component.

Method Detail

getBorderThickness

public final int getBorderThickness()

Returns the thickness of the border around the manager view. The default value is 2.

See Also:

setBorderThickness(int)

setBorderThickness

public final void setBorderThickness(int thickness)

Changes the thickness of the border around the manager view. The default value is 2.

See Also:

getBorderThickness()

getVerticalAdjustable

public final Adjustable getVerticalAdjustable()

Returns the vertical scrollbar. The default implementation for scrollbars in this class is the java.awt.Scrollbar class, but you can use any type of component that implements the Adjustable interface for the implementation of scrollbars. That is the reason why this method returns a Adjustable that you can cast in Scrollbar.

getHorizontalAdjustable

public final Adjustable getHorizontalAdjustable()

Returns the horizontal scrollbar. The default implementation for scrollbars in this class is the java.awt.Scrollbar class, but you can use any type of component that implements the Adjustable interface for the implementation of scrollbars. That is the reason why this method returns a Adjustable that you can cast in Scrollbar.

createManagerView

protected IlvManagerView createManagerView(IlvManager manager,
                                           IlvTransformer t)

Creates an IlvManagerView for the IlvScrollManagerView. This method is called by the constructor to create the IlvManagerView.
