Field Details

renderer

AbstractRenderer renderer

A renderer to wrap.

heightSet

private boolean heightSet

Flag saying that we updated height of the renderer we wrap. It allows to remove that property on split.

Constructor Details

GridItemRenderer

GridItemRenderer()

Method Details

addChild

public void addChild(IRenderer renderer)

Adds a child to the current renderer

Specified by:

addChild in interface IRenderer

Overrides:

addChild in class AbstractRenderer

Parameters:

renderer - a child to be added

getNextRenderer

public 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.

Returns:

new renderer instance

getProperty

public <T1> T1 getProperty(int key)

Gets the property from this entity. Compared to IPropertyContainer.getOwnProperty(int), this method can check parent's properties, styles, etc, depending on the origin of the instance

Specified by:

getProperty in interface IPropertyContainer

Overrides:

getProperty in class AbstractRenderer

Type Parameters:

T1 - the return type associated with the property

Parameters:

key - the property to be retrieved

Returns:

the value of the given property. null will be returned if the property value was not found

setProperty

public void setProperty(int property,
 Object value)

Sets a property for this entity.

Specified by:

setProperty in interface IPropertyContainer

Overrides:

setProperty in class AbstractRenderer

Parameters:

property - the property to be set

value - the value of the property

updateHeightsOnSplit

void updateHeightsOnSplit(float usedHeight,
 boolean wasHeightClipped,
 AbstractRenderer splitRenderer,
 AbstractRenderer overflowRenderer,
 boolean enlargeOccupiedAreaOnHeightWasClipped)

Overrides:

updateHeightsOnSplit in class AbstractRenderer

addChildRenderer

void addChildRenderer(IRenderer child)

Add the specified renderer to the end of children list and update its parent link to this.

Overrides:

addChildRenderer in class AbstractRenderer

Parameters:

child - the child renderer to be add

calculateHeight

float calculateHeight(float initialHeight)
