Method Detail

renderHeader

List<GridRenderer.RendererCommand> renderHeader(List<GridColumn.HeaderMetaData> headerMetaData,
                                                GridHeaderColumnRenderContext context,
                                                BaseGridRendererHelper.RenderingInformation renderingInformation,
                                                BiFunction<Boolean,GridColumn<?>,Boolean> columnRenderingConstraint)

Renders the column's Header..

Parameters:

headerMetaData - MetaData for the header

context - Contextual information to support rendering

renderingInformation - Calculated rendering information supporting rendering.

columnRenderingConstraint - Function to determine whether column should be rendered to the SelectionLayer

Returns:

renderHeaderContent

com.ait.lienzo.client.core.shape.Group renderHeaderContent(List<GridColumn.HeaderMetaData> headerMetaData,
                                                           GridHeaderColumnRenderContext context,
                                                           int headerRowIndex,
                                                           double blockWidth,
                                                           double rowHeight)

Renders the column's Header content.

Parameters:

headerMetaData - MetaData for the header

context - Contextual information to support rendering

headerRowIndex - Index of the header row being rendered. Zero based.

blockWidth - Width of the block of 'equal' header meta data objects.

rowHeight - Height of the header row.

Returns:

renderColumn

List<GridRenderer.RendererCommand> renderColumn(GridColumn<?> column,
                                                GridBodyColumnRenderContext context,
                                                BaseGridRendererHelper rendererHelper,
                                                BaseGridRendererHelper.RenderingInformation renderingInformation,
                                                BiFunction<Boolean,GridColumn<?>,Boolean> columnRenderingConstraint)

Renders the column.textual information to support rendering

Parameters:

column - The column to render

context - Contextual information to support rendering

rendererHelper - Helper for rendering.

renderingInformation - Calculated rendering information supporting rendering.

columnRenderingConstraint - Function to determine whether column should be rendered to the SelectionLayer

Returns:

renderCell

com.ait.lienzo.client.core.shape.Group renderCell(GridCell<T> cell,
                                                  GridBodyCellRenderContext context)

Renders a cell for the column for a row. Normally a column would use its logical index to retrieve the corresponding element from the row to be rendered.

Parameters:

cell - The cell to render

context - Contextual information to support rendering

Returns:
