Placing Geometry Managers/Widgets To add a geometry manager or widget to a window, click on the desired widget in the widgets pallete, and then click inside the manager/widget in which you want the new widget to be placed. For a geometry manager, a popup dialog will prompt you for its size (e.g. number of rows). Chose it and click 'Ok'. You may later edit this size. In each top-level window, set up geometry managers, with widgets and other geometry managers in them. Finally save the project, and possibly also generate source code.
