Connecting to a View Wrapper
The Investment application is nearly complete, with just a few more connections left to make. Most importantly, you need to connect the MainWindowView part to the secondary BuySecurityView and SellSecurityView parts.

1. Open the Composition Editor for the MainWindowView part.
2. Connect the clicked event of the Buy push button to the openWidget action of the BuySecurityView view wrapper part.
