layout element. Will terminate the current content area and initialize a new one.
Constructor and Description |
---|
AreaBreakRenderer(AreaBreak areaBreak)
Creates an AreaBreakRenderer.
|
Modifier and Type | Method and Description |
---|---|
void |
addChild(IRenderer renderer)
Adds a child to the current renderer
|
void |
deleteOwnProperty(int property)
Deletes the own property of this entity.
|
void |
draw(DrawContext drawContext)
Flushes the renderer subtree contents, i.e.
|
List<IRenderer> |
getChildRenderers()
Gets the child IRenderer s.
|
|
getDefaultProperty(int property)
Gets the default property from this entity.
|
IPropertyContainer |
getModelElement()
Gets the model element associated with this renderer.
|
IRenderer |
getNextRenderer()
Gets a new instance of this class to be used as a next renderer, after this renderer is used, if IRenderer.layout(LayoutContext) is called more than once.
|
LayoutArea |
getOccupiedArea()
Gets the resultant occupied area after the last call to the IRenderer.layout(LayoutContext) method.
|
|
getOwnProperty(int property)
Gets own property from this entity.
|
|
getProperty(int key)
Gets the property from this entity.
|
|
getProperty(int property, T1 defaultValue)
Gets a property from this entity or one of its hierarchical parents.
|
boolean |
hasOwnProperty(int property)
Checks if this entity has the specified property, i.e.
|
boolean |
hasProperty(int property)
Checks if this entity has the specified property.
|
boolean |
isFlushed()
Indicates whether this renderer is flushed or not, i.e.
|
LayoutResult |
layout(LayoutContext layoutContext)
This method simulates positioning of the renderer, including all of its children, and returns the LayoutResult , representing the layout result, including occupied area, status, i.e.
|
void |
move(float dx, float dy)
Moves the renderer subtree by the specified offset.
|
IRenderer |
setParent(IRenderer parent)
Explicitly sets this object as the child of another IRenderer in the renderer hierarchy.
|
void |
setProperty(int property, Object value)
Sets a property for this entity.

IRenderer
public LayoutResult layout(LayoutContext layoutContext)
IRenderer
LayoutResult
, representing the layout result, including occupied area, status, i.e. if there was enough place to fit the renderer subtree, etc. LayoutResult
can be extended to return custom layout results for custom elements, e.g. TextRenderer
uses TextLayoutResult
as its result. This method can be called standalone to learn how much area the renderer subtree needs, or can be called before IRenderer.draw(DrawContext)
, to prepare the renderer to be flushed to the output stream.
