Protect Worksheet
Use Range.protectSheet(String) to set worksheet protection.
public void onClick$toggleSheetProtection(Event event) {
final Worksheet sheet = spreadsheet.getSelectedSheet();
boolean sheetProtection = !sheet.getProtect();
Ranges.range(sheet).protectSheet(sheetProtection ? "password" : null);
}
Lock cells
Use CellStyle.setLocked(Boolean) to lock cell. Use Range.setStyle(CellStyle) to update cell style.
public void onClick$toggleLockCells(Event event) {
final Worksheet sheet = spreadsheet.getSelectedSheet();
boolean lock = !Utils.getOrCreateCell(sheet, topRow, leftCol).getCellStyle().getLocked();
for (int r = topRow; r <= bottomRow; r++) {
for (int c = leftCol; c <= rightCol; c++) {
Cell cell = Utils.getOrCreateCell(sheet, r, c);
CellStyle cellStyle = cell.getCellStyle();
if (cellStyle.getLocked() != lock) {
CellStyle newCellStyle = cloneStyle(cellStyle, sheet.getBook());
newCellStyle.setLocked(lock);
Ranges.range(sheet, r, c).setStyle(newCellStyle);
}
}
}
}
