UIManager
Last updated at 7:06 am UTC on 28 October 2020
The UIManager class has been part of Squeak since version 3.9.
The framework allows for cross-UI-framework requests to be made from Squeak code. It is accessible as:
UIManager default


Such requests are for example
 chooseDirectory: label from: dir
 chooseFromDictionary: aDictionary title: aString
 confirm: queryString trueChoice: trueChoice falseChoice: falseChoice 
 edit: aText label: labelString
 inform: aMessage title: aTitle
 request: queryString initialAnswer: defaultAnswer 

or a picklist
 chooseFrom: aList lines: linesArray title: aString
	"Choose an item from the given list. Answer the index of the selected item."

Class comment:
UIManager is a dispatcher for various user interface requests, such as menu and dialog interactions. An instance of UIManager is associated with each Project to implement the appropriate functions for Morphic (MorphicUIManager), MVC or other user interfaces.
