Source Cell

Use onCellFocused event to get the current cell. Use onCellSelection event to get the current selection range.

Spreadsheet spreadsheet;
Cell currentCell;
Rect selection;
public void onCellFocused$spreadsheet(CellEvent event) {
	currentCell = Utils.getCell(event.getSheet(), event.getRow(), event.getColumn());
}
public void onCellSelection$spreadsheet() {
	selection = spreadsheet.getSelection();
}

Fill cells

Intbox fillCells;
Combobox fillOrientation;
public void onClick$fill() {
	String orientation = (String)fillOrientation.getSelectedItem().getValue();
	if ("down".equals(orientation)) {
		int leftCol = currentCell.getColumnIndex();
		int topRow = currentCell.getRowIndex();
		int rightCol = leftCol;
		int btmRow = topRow + fillCells.getValue();
		Ranges.range(spreadsheet.getSelectedSheet(), topRow, leftCol, btmRow, rightCol).fillDown();
	} else if ("right".equals(orientation)) {
		int leftCol = currentCell.getColumnIndex();
		int topRow = currentCell.getRowIndex();
		int rightCol = leftCol + fillCells.getValue();
		int btmRow = topRow;
		Ranges.range(spreadsheet.getSelectedSheet(), topRow, leftCol, btmRow, rightCol).fillRight();
	} else if ("left".equals(orientation)) {
		int rightCol = currentCell.getColumnIndex();
		int leftCol = rightCol - fillCells.getValue();
		int topRow = currentCell.getRowIndex();
		int btmRow = topRow;
		Ranges.range(spreadsheet.getSelectedSheet(), topRow, leftCol, btmRow, rightCol).fillLeft();
	} else if ("up".equals(orientation)) {
		int btmRow = currentCell.getRowIndex();
		int topRow = btmRow - fillCells.getValue();
		int leftCol = currentCell.getColumnIndex();
		int rightCol = leftCol;
		Ranges.range(spreadsheet.getSelectedSheet(), topRow, leftCol, btmRow, rightCol).fillUp();
	}
}

AutoFill

AutoFill can specify the fill type and destination range to fill.

public void onClick$autofill() {
	if (selection == null) {
		alert("Selection can not be empty");
		return;
	}
		
	final Worksheet worksheet = spreadsheet.getSelectedSheet();
	final int topRow = selection.getTop();
	final int leftCol = selection.getLeft();
	final int btmRow = selection.getBottom();
	final int rightCol = selection.getRight();
		
	final int fillCells = autoFillCells.getValue();
		
	//fill down
	Range autofillRange = 
		Ranges.range(worksheet, topRow, leftCol, btmRow + fillCells, leftCol);
	int type = Range.FILL_DEFAULT;
	String fillType = (String) autofillType.getSelectedItem().getValue();
	if ("copy".equals(fillType)) {
		type = Range.FILL_COPY;
	}
	
	final Range srcRange = 
		Ranges.range(worksheet, topRow, leftCol, btmRow, rightCol);
		
	srcRange.autoFill(autofillRange, type);
}
