Disable Functions

Spreadsheet provides API to disable its functions. The API can be very useful when you implement your user permission features. In the example application below, since we disable all sheet related functions except one, you can see the corresponding menu items are disabled (in grey color).

To achieve this, simply call io.keikai.ui.Spreadsheet

    @Wire
    private Spreadsheet ss;
    
    @Listen("onCheck = #add")
    public void disableAdd(CheckEvent event) {
        ss.disableUserAction(AuxAction.ADD_SHEET, !event.isChecked());
    }
...
}

Except sheet operations, you can also disable functions on the toolbar and the context menu. Take a look at io.keikai.ui.AuxAction for a complete list of functions you can disable.
