Hi all,
-- The text below is from documentation. The only difference is that the method #createText: is replaced by #createScrolledText: . After this change debugger popups saying he does not understand the "leftAttachment". At the same time description of this method states that "This resource is valid only when the receiver's parent is a CwForm." which is OK in my case. Can somebody explain why this doesn`t work and propose the working example for scroled text? And thank you in advance. | shell form drawing text | shell := CwTopLevelShell createApplicationShell: 'shell' argBlock: [:w | w title: 'Form Example']. form := shell createForm: 'form' argBlock: nil. form manageChild. drawing := form createDrawingArea: 'drawing' argBlock: [:w | w borderWidth: 1; width: 200; height: 200; leftAttachment: XmATTACHFORM; leftOffset: 2; rightAttachment: XmATTACHPOSITION; rightPosition: 67; topAttachment: XmATTACHFORM; topOffset: 2; bottomAttachment: XmATTACHFORM; bottomOffset: 2]. drawing manageChild. text := form createScrolledText: 'text' argBlock: [:w | w leftAttachment: XmATTACHWIDGET; leftWidget: drawing; leftOffset: 2; rightAttachment: XmATTACHFORM; rightOffset: 2; topAttachment: XmATTACHFORM; topOffset: 2; bottomAttachment: XmATTACHFORM; bottomOffset: 2]. text manageChild. shell realizeWidget.

Hello,
-- I think this concept comes from the original Motif specification, but a ScrolledText is really a ScrolledWindow composite which manages/decorates a Text. It is the scrolled window that has the attachments to the form...not the text. Therefore in your modified example, the 'w' is a CwText...for attachment manipulation you want it's parent, the CwScrolledWindow, since that is the thing attached to the form. Change '[:w | w leftAttachment.......' to '[:w | w parent leftAttachment........' -- Seth On Wednesday, February 8, 2017 at 5:35:07 PM UTC-5, [hidden email] wrote:
