Subclassing MFC

Author	Message
Scott O'Frie #1 / 7	Subclassing MFC Hi, I want to add a Windows control, say CEdit, to my dialog form. That's the easy part. I want that CEdit control on the dialog form to reference my subclassed CEdit, MyCEdit. How do you make the connection that the control that you placed on the form references your subclassed control? Thanks, Scott

Michael D. Obe #2 / 7	Subclassing MFC Assuming you have created a new class based on CEdit, go to the Class Wizard and add a control variable for your CEdit control. Select MyCEdit as the variable type. Mike Ober. Quote: > Hi, > I want to add a Windows control, say CEdit, to my dialog form. That's the > easy part.

Scott, If you derive a class from CEdit using the Class View, New Class facility - when you come to add a member variable to an edit control on a dialog Class Wizard allows you to choose between a normal CEdit control or your own derived CMyEdit class.

David Wilkinso #4 / 7	Subclassing MFC Scott: Even if your class does not show up in ClassWizard you can add a CEdit control variable and simply change the designation in the dilaog header from CEdit to CMyEdit (and #include the MyEdit header). The DDX_Control mechanism which MFC uses to attach a CEdit control variable is in no way different from the one it uses to attach your derived control. Equivalently you can do it yourself in InitDialog using SubclassDlgItem(). HTH, David Wilkinson ==================== Quote: > >I want to add a Windows control, say CEdit, to my dialog form.

Scott O'Frie #5 / 7	Subclassing MFC To all, Thanks for the insight. It now works as I wanted it to. The time I burned looking through the documentation, I could have spent shootin' the breeze, Dilbert style. I appreciate the time from all.

Paul Quall #6 / 7	Subclassing MFC I have done a lot of this lately.. And what I miss in MFC is what Delphi does naturally.. If you derive a class based on a listbox or anything else, you can publish it on the component pallete and then use that component in ANY project later on just like dropping the component from your pallette on a dlg in Visual studio. I wish the visual studio designers would somehow work this into play so that when I am forced to write in VC++ I don't spend a bunch of time figuring out where to put the SubClassDlgItem() and how to get that to work.. If you have already added the functionality, why should you not automatically be able to use that component in all of you future products.. Paul Quote: > To all, > Thanks for the insight.

Joseph M. Newcome #7 / 7	Subclassing MFC Well, there is a component gallery you can add things to, and if you're calling SubclassDlgItem you're not using MFC optimally. I've not called SubclassDlgItem except in a couple really weird cases. joe Quote: >I have done a lot of this lately.. And what I miss in MFC is what Delphi >does naturally..
