Composer

Source cell

We can use onCellFocused event to get the cell as source to copy.

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

Fill cell

Fill down

Intbox rows;
Intbox columns;
Button fillDown;
public void onClick$fillDown() {
	Integer rowNum = rows.getValue();
	if (currentCell == null || rowNum == null)
		return;
		
	Sheet sheet = spreadsheet.getSelectedSheet();
	int top = currentCell.getRowIndex();
	int left = currentCell.getColumnIndex();
	Range downRange = Ranges.range(sheet, top, left, top + rowNum, left);
	downRange.fillDown();
}

Fill right

Button fillRight;
public void onClick$fillRight() {
	Integer colNum = columns.getValue();
	if (currentCell == null || colNum == null)
		return;
		
	Sheet sheet = spreadsheet.getSelectedSheet();
	int top = currentCell.getRowIndex();
	int left = currentCell.getColumnIndex();
	Range rightRange = Ranges.range(sheet, top, left, top, left + colNum);
	rightRange.fillRight();
}

Fill left

Button fillLeft;
public void onClick$fillLeft() {
	Integer colNum = columns.getValue();
	if (currentCell == null || colNum == null)
		return;
		
	Sheet sheet = spreadsheet.getSelectedSheet();
	int top = currentCell.getRowIndex();
	int left = currentCell.getColumnIndex();
	Range leftRange = Ranges.range(sheet, top, left - colNum, top, left);
	leftRange.fillLeft();
}

Fill up

Button fillUp;
public void onClick$fillUp() {
	Integer rowNum = rows.getValue();
	if (currentCell == null || rowNum == null)
		return;

	Sheet sheet = spreadsheet.getSelectedSheet();
	int top = currentCell.getRowIndex();
	int left = currentCell.getColumnIndex();
	Range upRange = Ranges.range(sheet, top - rowNum, left, top, left);
	upRange.fillUp();
}

Auto fill, the auto fill can specify fill type and destination range to fill.

Button autoFill;
public void onClick$autoFill() {
	Integer rowNum = rows.getValue();
	Integer colNum = columns.getValue();
	if (currentCell == null || rowNum == null || colNum == null)
		return;
		
	Sheet sheet = spreadsheet.getSelectedSheet();
	int top = currentCell.getRowIndex();
	int left = currentCell.getColumnIndex();
	Range range = Ranges.range(sheet, top, left);
	Range leftRange = Ranges.range(sheet, top, left, top , left + colNum);
	range.autoFill(leftRange, Range.FILL_COPY);

	Range downRange = Ranges.range(sheet, top, left, top + rowNum, left);
	range.autoFill(downRange, Range.FILL_COPY);
	}
