Current Range

We can get the user's selection range from the 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;
	}
}
