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;
}
}
