ZK Spreadsheet support drag fill, auto fill cell's value.

Drag Fill

The drag fill is base on Range.autofill(Range, Integer)

Copy

1. Select a range


2. Mouse over right bottom border, mouse cursor will change to cross, drag to expend selection range


3. Release mouse to perform auto fill

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;
		
	Worksheet 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;
		
	Worksheet 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;
		
	Worksheet 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;

	Worksheet 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 utoFill;
public void onClick$autoFill() {
	Integer rowNum = rows.getValue();
	Integer colNum = columns.getValue();
	if (currentCell == null || rowNum == null || colNum == null)
		return;
		
	Worksheet 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);
	}
