AbtListView's #primCreateWidget is defective ... cannot effectively be subclasses

Administrator

Unlike AbtBasicView which uses the part's #cwWidgetClass method to determine what class of CW widget to instantiate, AbtListView ignores #cwWidgetClass.

The work-around to this is tedious, requiring one to override AbtListView>>#primCreateWidget and CwWidget>>#createScrolledList:argBlock:.
(The latter calls CwWidget>>#createList:argBlock: which hard-codes CwList as the CW widget class.)

Hi Richard,

I've opened a case 53437 to investigate how to make it easier to subclass AbtListView.
