ZK Spreadsheet Essentials/Working with ZK Spreadsheet/Configure and Control ZK Spreadsheet/Insert Range

ZK Spreadsheet can use Range.insert to inser row or column.

Scenario

User right click to open a menu and inert row or column.

ZUML Example

<zk>
<div height="100%" width="100%" apply="demo.InsertRangeComposer">
	<div height="3px"></div>
	<menupopup id="cellMenupopup">
		<menuitem id="shiftCellRight" label="Shift cells right"></menuitem>
		<menuitem id="shiftCellDown" label="Shift cells down"/>
		<menuitem id="insertEntireRow" label="Entire row" />
		<menuitem id="insertEntireColumn" label="Entire column" />
	</menupopup>
	<spreadsheet id="spreadsheet" src="/demo_sample.xls"	
			maxrows="200" 
			maxcolumns="40"
			width="100%"
			height="450px"></spreadsheet>
</div>
</zk>

Open menu

We can use onCellRightClick to get the current mouse position and open popup.

int rowIndex;
int colIndex;
Sheet currentSheet;
Spreadsheet spreadsheet;
Menupopup cellMenupopup;
public void onCellRightClick$spreadsheet(CellMouseEvent event) {
	rowIndex = event.getRow();
	colIndex = event.getColumn();
	currentSheet = event.getSheet();
	cellMenupopup.open(event.getPageX(), event.getPageY());
}

Shift cells right

Menuitem shiftCellRight;
public void onClick$shiftCellRight() {
	Range rng = Ranges.range(currentSheet, rowIndex, colIndex);
	rng.insert(Range.SHIFT_RIGHT, Range.FORMAT_RIGHTBELOW);
}

Shift cells down

public void onClick$shiftCellDown() {
	final Range rng = Ranges.range(currentSheet, rowIndex, colIndex);
	rng.insert(Range.SHIFT_DOWN, Range.FORMAT_LEFTABOVE);
}

Insert entire row

public void onClick$insertEntireRow() {
	Row row = currentSheet.getRow(rowIndex);
	int lCol = row.getFirstCellNum();
	int rCol  = row.getLastCellNum();
	for(int colIdx = lCol; colIdx < rCol; colIdx++) {
		final Range rng = Ranges.range(currentSheet, rowIndex,	colIdx);
		rng.insert(Range.SHIFT_DOWN, Range.FORMAT_LEFTABOVE);
	}
}

Insert entire column

public void onClick$insertEntireColumn() {
	int tRow = currentSheet.getFirstRowNum();
	int bRow = currentSheet.getPhysicalNumberOfRows();
	for (int rowIdx = tRow; rowIdx < bRow; rowIdx++) {
		final Range rng = Ranges.range(currentSheet, rowIdx, colIndex);
		rng.insert(Range.SHIFT_RIGHT, Range.FORMAT_RIGHTBELOW);
	}	
}
