Example: Changing prerequisites for the application DevelopChooser
This example uses the application you created in Example: Creating the application DevelopChooser. This section describes what to do if an application needs different prerequisites than the ones initially set.
The purpose of DevelopChooser is to display a list of sample application. To that end, a graphical user interface is needed. Graphical user interface components are found in CommonWidgets. This means you need to change the prerequisites of DevelopChooser, to include CommonWidgets:
1. In an Application Manager, select DevelopChooser.
2. From a Prerequisites menu, select Change. A dialog window opens, with the available applications listed on the left, and the selected immediate prerequisites listed on the right. The two buttons in the center will cause selected applications to move between the two lists. Kernel is the only immediate prerequisite. Note that you cannot remove Kernel as a prerequisite.
3. Click on the new prerequisite application CommonWidgets and then >> to select it. Note that Kernel disappears, because this dialog lists only immediate prerequisites.
4. Select OK. In the Application Manager, the prerequisites pane should now list the new prerequisite.
