Constructor Details

GridContainerRenderer
Creates a Grid renderer from its corresponding layout object.- Parameters:
modelElement
- theGridContainer
which this object should manage
-
-
Method Details
-
getNextRenderer
Gets a new instance of this class to be used as a next renderer, after this renderer is used, ifIRenderer.layout(LayoutContext)
is called more than once.- Returns:
- new renderer instance
-
layout
This method simulates positioning of the renderer, including all of its children, and returns theLayoutResult
, 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
usesTextLayoutResult
as its result. This method can be called standalone to learn how much area the renderer subtree needs, or can be called beforeIRenderer.draw(DrawContext)
, to prepare the renderer to be flushed to the output stream.- Specified by:
layout
in interfaceIRenderer
- Overrides:
layout
in classBlockRenderer
- Parameters:
layoutContext
- the description of layout area and any other additional information- Returns:
- result of the layout process
-
addChild
Adds a child to the current renderer- Specified by:
addChild
in interfaceIRenderer
- Overrides:
addChild
in classAbstractRenderer
- Parameters:
renderer
- a child to be added
-
determineCollapsingMargins
Calculates collapsing margins value. It's based on browser behavior. Always returning true somehow also almost works. -

processLayoutResult
private static int processLayoutResult(GridContainerRenderer.GridLayoutResult layoutResult, GridCell cell, LayoutResult cellResult) -
