In Example: Creating the configuration map Chooser Map, you grouped the Develop applications into the configuration map Chooser Map. Suppose, for the sake of this example, you were to place the prerequisite DevelopmentWidget in a required map. To do this, you would create a separate configuration map for DevelopmentWidget and then add it to Chooser Map as a required map.
To create a configuration map for DevelopmentWidget, do the following:
In the displayed dialoge, select DevelopmentWidget, its edition, >>, and then OK.
To release, and thus add, Chooser Required Map to the configuration map Chooser Map, do the following:
For configuration maps that contain platform-specific components, you would, at this point, enter a Smalltalk Boolean expression that tests for the appropriate platform. Specifying Boolean expressions for the lineups provides sample expressions that test for different platforms. You can also find samples by examining the expressions used for other configuration map lineups.
Chooser Required Map is released to Chooser Map lineup. Also, a prompter is displayed, asking if you want to add another configuration map to the lineup.
Complete the lineup by deleting DevelopmentWidget from Chooser Map:
At this point, a Configuration Maps Browser resembles the following when
you select Chooser Map and its edition:
You might want to add the application DevelopScreenCapture to Chooser Map or enter a description of the map in the description pane (lower right). However, after you complete the Chooser Map lineup, test it by loading Chooser Map again. To do this, select Chooser Map and its edition; then select Load Edition With Required Maps from the Editions menu. The applications in Chooser Map should load successfully.
