Method Detail

getCellRendererComponent

public Object getCellRendererComponent(Object pParentComponent,
                                       IDataPage pDataPage,
                                       int pRowNumber,
                                       IDataRow pDataRow,
                                       String pColumnName,
                                       boolean pIsSelected,
                                       boolean pHasFocus)

Configures a IComponent for rendering. The IComponent can be reused for performance reasons. After a new call of getCellRendererComponent, the previous IComponent can't be used for rendering anymore.

Parameters:

pParentComponent - the Parent Component from which.

pDataPage - the DataPage of the row to be rendered.

pRowNumber - the row number of the row to be rendered.

pDataRow - the row to be rendered (is the same as pDataPage.getRow(pRowNumber)).

pColumnName - the column name to be rendered.

pIsSelected - true, if the cell is selected (shown with selected background).

pHasFocus - true, if the cell has the focus (cell is the current editing cell).

Returns:

the renderer Component. It can only be used until the next call of this function.
