Appendix B: Custom Property Sheet API Reference

Although you can use the default property sheet to get visual components working quickly in Xclesius,

to provide the best user experience, you can create a customer property sheet for your add-on. Custom

connections cannot use the default property sheet, so you must create a custom property sheet for

connection add-ons.

When you build a custom property sheet, you have full control over the layout and the properties available

for users to view, edit, and bind to the spreadsheet.

Note:

Only simple data types are supported including Object, Number and Array.

12.1 High-level steps for creating custom property sheets

This section provides a high-level description for each step required to create a custom property sheet.

For a walkthrough on creating a custom property sheet tht includes more details for each steps, see

the

SAP BusinessObjects Dashboards SDK Tutorial 4

available with your Dashboards SDK

documentation.

To see an example custom property sheet for a visual component, refer to the CustomPropSheetHo

rizontalSlider sample add-on component.

Create an Adobe Flex project for your custom property sheet. You can use the top-level application

MXML to create your property sheet..

Drag and drop Adobe Flex MXML visual components to create your custom property sheet user

interface.

Create an instance of the custom property sheet proxy (xcelsius.propertySheets.impl.Prop

ertySheetExternalProxy) that allows communication between the custom property sheet and

Dashboards.

For example:

import xcelsius.propertySheets.impl.PropertySheetExternalProxy;

import xcelsius.propertySheets.interfaces.IPropertySheetProxy;

// Create an instance of the proxy between the custom property sheet and Dashboards.

protected var proxy:IPropertySheetProxy = new PropertySheetExternalProxy();

The custom property sheet loads every time the user selects the component or the connection to

view its properties in Dashboards. Add in initialization ActionScript code to initialize the custom

property sheet when it is loaded and to notify Dashboards (via the proxy) when the custom property

sheet has finished loading.
