Constructor Detail

DirectPaintingSWTScrollContainer

public DirectPaintingSWTScrollContainer(ScrollingTICComponent ticComponent,
                                        org.eclipse.swt.widgets.Composite parent,
                                        int style,
                                        TICComponent outputComponent)

Creates a new instance of this class that forwards key and mouse events to outputComponent. The mouse events will have transformed coordinates according to the current scroll position.

Parameters:

ticComponent - the TIC component associated with the returned instance (the scroll container)

parent - the SWT parent composite

style - the SWT style attributes

outputComponent - the TIC component to be scrolled by the returned instance

Method Detail
