IWidgetCreator is an interface that was introduced in 1996 for integrating TextFrameWidgets into LayoutWidgets. For more details see build notes from 6/6/1996 and 6/12/1996:
Integration of TextFrameWidgets into LayoutWidgets
1) The LayoutWidget is now derived from PanelView and PanelEH to be able to contain children. The TextFrameWidget (TextEditor) is hooked to the LayoutControlView as a child.
2) To solve the synchronization problems with different transforms (i.e. when the user scrolls) the TextFrameWidget uses now Panoramas.
3) IWidgetCreator There is a new interface IWidgetCreator which has to be added to PageItem bosses (like FramePageItem) to support the creation of widgets for paritular pageitems. For example the FrameWidgetCreator creates TextFrameWidgets (= TextEditors as widgets).
4) TextSelectTracker creates TextFrameWidgets The TextSelectTracker has been modified to be able to create a TextFrameWidget. In the EndTracking() it asks the pageitem (TextFrame) for an IWidgetCreator. The WidgetCreator will only create a new TextFrameWidget if it does not found another at the child level of the parent widget (here: LayoutControlView). This ensures that the TextFrameWidgets are shared at each LayoutCV.
5) Creation of TextFrameWidgets as an option Now the creation of the new TextEditor as a widget is available as an option. If you want to create a widget you have to out comment or remove the IID_ITEXTEDITOR from the LayoutWidget in Layout.r (LayoutWidget). There is also a debugging mode that you can activate/deactivate with MacControlKey + OptionKey + CmdKey + Click. In the debugging mode the Draw() method of the widget is enabled so you can see the widget.
