Re: Inheritance and MFC

Hi Nobody,

To create a control, like a grid control, you'll likely want to start with
something similar that is already derived from a CWnd and has some of the
properties you want to use. Perhaps something like this:

Hi Tom,


I posted what was relevant.


It does not.


Yes.

I guess that is what I am doing.
I am trying to create a control.
It is a control, but does not contain any controls.
I am trying to add controls to my control. i.e. Scrollbars

I noticed that the more I use the grid object, the more I have to keep
adding scroll bars for pan, zoom, etc.
So, my idea was to make a CWnd GridSB Class that implements Scrollbars.
That class inherits from the Grid CObject class.
Then, I can leave the scroll bars inside of the CGrid Object, instead of
Creating scroll bars each time.

This is basically what I have.

CGrid : public CObject
{
   //Bunch of stuff
}

CGridSB: public CGrid, public CWnd
{
    CScrollbar sb;
    CreateScrollbars();
    SetScreenRect(){ PositionScrollbars(); }
}

CView::OnDraw()
{
    CGridSB sb;
    sb.SetScreenRect(Rect);
    sb.OnDraw(pDC);
}
