Stretch a docked CDialogBar.

I'm feeling pretty dumb right now, but I can't seem to get my docked CDialogBar to stretch the length of a window. I want my dialog bar to be docked to the top (the user can't change this). In the dialog bar, I want certain controls to be anchored to the right side of the dialog. So when the window stretches, I want the dialog bar to stretch as well. However my CDialogBar derivative isn't receiving the WM_SIZE message when the frame window is resized.

In my frame's OnCreate method (it's a frame not using doc/view architecture), I have the following code:

Code:

---

    m_bar.Create( this, IDD_DIALOG1, WS_CHILD | WS_VISIBLE | CBRS_TOP | CBRS_SIZE_FIXED, IDD_DIALOG1 );
    m_bar.EnableDocking( CBRS_ALIGN_TOP );
    EnableDocking( CBRS_ALIGN_TOP );
    DockControlBar( &m_bar );

---

Then in my frame's OnSize message handler, I call:

Code:

---

    RepositionBars( IDD_DIALOG1, IDD_DIALOG1, 0 );

---

I have a CDialogBar derivative that just handles the WM_SIZE message to move child controls, but it's never hit.

What am I doing wrong?

Well then, send WM_SIZE to dialog bar from the frame's WM_SIZE hander.

That's what I'm doing now, but that seems like a hack to me.

Every attempt to change of default behavior is a "hack". ;)

To avoid sending WM_SIZE which indeed is not elegant, override CDialogBar::CalcFixedLayout and force bStretch to TRUE.

Code:

---

CSize CMyDialogBar::CalcFixedLayout(BOOL bStretch, BOOL bHorz)
{
  if(!IsFloating())
  {
      bStretch = TRUE;
  }
  return CDialogBar::CalcFixedLayout(bStretch, bHorz);
}
