Constructor Details

LayoutEnv

public LayoutEnv()

Instantiates a default layout environment.

LayoutEnv

public LayoutEnv(FontService oFontService,
 Service oImageService,
 HrefService oHrefService,
 LayoutDriver oDriver)

Instantiates a LayoutEnv from the given arguments.

Parameters:

oFontService - a font service.

oImageService - an image service.

oHrefService - an href service.

oDriver - a layout driver.

Method Details

layoutHandler

public void layoutHandler(LayoutHandler pHandler)

Sets the layout handler that processes output from the layout.

Parameters:

pHandler - the object to redirect the draw responsibilities to.

layoutHandler

public LayoutHandler layoutHandler()

Gets the layout handler that processes output from the layout.

Returns:

LayoutHandler, the object to redirect the draw responsibilities to.

getHrefService

public HrefService getHrefService()

Gets the HrefService that will resolve href content for protoable node based on their content. It will load href urls and provide accessors to the required href information.

Returns:

the HrefService to resolve hrefs with.

setFontService

public void setFontService(FontService oFontService)

Sets the font service to be used with this layout env.

getFontService

public FontService getFontService()

Gets the font service to be used with this layout env.

setDriver

public LayoutDriver setDriver(LayoutDriver oDriver)

Sets the driver, returning previous

getTextContext

public TextContext getTextContext()

Gets the text context. The text context is an opaque AXTE object that allows the layout of multiple text to share a number of serially-reusable objects. These objects are expensive to create. layout code uses this common text context object when creating text objects, in order to effect that sharing.

Returns:

The text context object.

setModel

public void setModel(Model oModel)

Sets the model. We will use this for creating new nodes.

Parameters:

oModel - a model.

getModel

public Model getModel()

Gets the model. We will use this for creating new nodes.

Returns:

a model.

setTextResolver

public void setTextResolver(TextResolver pResolver)

Sets the text resolver interface - acts as callback for xfa:embed references

getTextResolver

public TextResolver getTextResolver()

Gets the text resolver interface - acts as callback for xfa:embed references

getLayoutDriver

public LayoutDriver getLayoutDriver()

Gets the LayoutDriver associated with this environment.

Returns:

a LayoutDriver.

getMetaFileData

public int getMetaFileData(byte[] pClipData,
 int size,
 Rect oDrawArea)

Gets meta file data.

setClipRect

public void setClipRect(Rect oRect)

sets the clipping rectangle.

renderText

public boolean renderText(LayoutHandler oLayoutHandler,
 TextDisplay oDisplay,
 CoordPair oOffset,
 boolean bWrap,
 boolean bTruncate,
 Rect oInvalidatedRect)

 boolean bWrap,
 boolean bTruncate,
 Angle oAngle,
 Rect oInvalidatedRect)
