Auto Fill - Drag Fill

You can drag the Fill Handle(the small black square at the bottom right) to copy cells in a simple dragging. The drag fill is base on Range's fill functions.

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

Fill in range

Scenario

User can input how many rows or how many columns to fill from a selected cell.

ZUML Example

<zk>
<div height="100%" width="100%" apply="demo.AutofillComposer">
	<div height="3px"></div>
	<div>
	Fill rows <intbox id="rows"/>, columns <intbox id="columns"/>
	</div>
	<div>	
		<button id="fillDown" label="Fill down" mold="trendy"></button>
		<button id="fillRight" label="Fill right" mold="trendy"></button>
		<button id="fillLeft" label="Fill left" mold="trendy"></button>
		<button id="fillUp" label="Fill up" mold="trendy"></button>
		<button id="autofill" label="Auto fill" mold="trendy"></button>
	</div>
	<spreadsheet id="spreadsheet" src="/Untitled"	
			maxrows="200" 
			maxcolumns="40"
			width="100%"
			height="450px"></spreadsheet>
</div>
</zk>

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();
}
