CompositePiece
public CompositePiece(CompositeEntry[] entries)
Constructs a CompositePiece with the given entries.- Parameters:
entries
- an array of entries that make up this PrintPiece.
-
CompositePiece
public CompositePiece(CompositeEntry[] entries, org.eclipse.swt.graphics.Point size)
Constructs a CompositePrintPiece with the given entries and explicit size. This constructor will increase the explicit size to completely contain any child entries which extend outside the given size.- Parameters:
entries
- an array of entries that make up this PrintPiece.size

CompositePiece
public CompositePiece(java.util.List entries)
Constructs a composite PrintPiece with the given entries.- Parameters:
entries
- an array of entries that make up this PrintPiece.
-
CompositePiece
public CompositePiece(java.util.List entries, org.eclipse.swt.graphics.Point size)
Constructs a composite PrintPiece with the given entries and minimum size.- Parameters:
entries
- a list of CompositeEntry objects describing the child PrintPieces.size
- a hint indicating the minimum size that should be reported from getSize(). This constructor increase this size to fit any entries that extend outside the given size.

getSize
public org.eclipse.swt.graphics.Point getSize()
Description copied from interface:PrintPiece
Returns the dimensions of this PrintPiece, in pixels.- Specified by:
getSize
in interfacePrintPiece
- Returns:
- the dimensions of this PrintPiece, in pixels.
-
paint
public void paint(org.eclipse.swt.graphics.GC gc, int x, int y)
Description copied from interface:PrintPiece
Draws this PrintPiece on the given graphics device, at the given coordinates.- Specified by:
paint
in interfacePrintPiece
- Parameters:
gc
- a graphics context for the graphics device.x
- the x coordinate where this PrintPiece will be drawn.y
- the x coordinate where this PrintPiece will be drawn.
-
dispose
public void dispose()
Description copied from interface:PrintPiece
Disposes the system resources allocated by this PrintPiece. The dispose method is not a permanent disposal of a PrintPiece. It is intended to reclaim system resources, however future calls to paint(GC,int,int) may require that the resources be allocated again.- Specified by:
dispose
in interfacePrintPiece
