Method Detail

getCellRendererComponent

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

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.
