This method does not replace all rows in the display; it replaces the row values starting at the specified start index through the length of the the specified values. You must call setRowCount(int) to set the total number of rows in the display. You should also use setRowCount(int) to remove rows when the total number of rows decreases.

Parameters
start the start index of the data
values the values within the range

public abstract void setSelectionModel (SelectionModel<? super T> selectionModel)

Parameters
selectionModel the SelectionModel

public abstract void setVisibleRangeAndClearData (Range range, boolean forceRangeChangeEvent)

Set the visible range and clear the current visible data.

If the second argument forceRangeChangeEvent is true, a RangeChangeEvent will be fired even if the range does not change. If false, a RangeChangeEvent will only be fired if the range changes.

Parameters
range the new Range
forceRangeChangeEvent true to fire a RangeChangeEvent even if the Range doesn't change
