How to add a FileChooser and DropDown inside an Eclipse FormToolKit

I want to add a FileChooser and a DropDown inside a formToolKit of eclipse. I did not find any开发者_JS百科 create method with the mentioned components.

How to get the desired output.

When the toolkit does't provide create* methods for the widget, you can always create the widget as usual, and then use toolkit.adapt() methods
