JamSelectionList_TJamSelectionListJamSelectionList_TJamSelectionList
Syntax
Pascal
TJamSelectionList = class(TJamBaseSelectionList);

This class is used as a property of the JamShellLink component for managing the list of selected paths that the user selects with shell controls that have the CheckBoxes property set to True. You can modify the list using the AddPathToSelection and RemovePathFromSelection method. You can save or load the list using the SaveToIniFile and LoadFromIniFile methods. You can access the list of selected paths using the Paths property, which is of type TStrings and so inherits the typical methods like GetText, SaveToFile, Clear etc. With FindNext you can enumerate the files of the current selection.
