ZUML Example

<zk>
<div height="100%" width="100%" apply="org.zkoss.zssessentials.config.MoveRangeComposer">
	<div height="3px"></div>
	Row: <intbox id="moveRows" value="0"/>, Col: <intbox id="moveCols" value="0"/> 
	<button id="moveBtn" label="Move Current Selection" mold="trendy"></button>
	<spreadsheet id="spreadsheet"  src="/WEB-INF/excel/config/demo_sample.xls"	
			maxrows="200" 
			maxcolumns="40"
			width="100%"
			height="450px"></spreadsheet>
</div>
</zk>

Current range

We can get user's selection range from onCellSelection event

Spreadsheet spreadsheet;
Range currentRange;
public void onCellSelection$spreadsheet(CellSelectionEvent event) {
	currentRange = Ranges.range(event.getSheet(), event.getTop(), event.getLeft(),
			event.getBottom(), event.getRight());
}

Move range

Intbox moveRows;
Intbox moveCols;
Button moveBtn;
public void onClick$moveBtn() {
	Integer row = moveRows.getValue();
	Integer col = moveCols.getValue();
	if (currentRange != null && row != null && col != null) {
		currentRange.move(row, col);
		currentRange = null;
	}
}
