FIX2:Release gripper gap without CMainFrame

[Eric Hu]

Must,You defined one bool flag and dockbar ID in your class.

like this:

class CFlatToolBar : public CToolBar

{

...

protected:

BOOL m_bInRecalcNC;

UINT m_nDockBarID;

...

}

By default,the m_bInRecalcNC is FALSE ,then the m_nDockBarID

you don't need to deine it.


void CFlatToolBar::OnWindowPosChanged(LPWINDOWPOS lpwp)

{

CToolBar::OnWindowPosChanged(lpwp);


if (m_bInRecalcNC) return;


UINT nDockBarID = GetParent()->GetDlgCtrlID();


// Return if dropped at same location

if (nDockBarID == m_nDockBarID // no docking side change

&& (lpwp->flags & SWP_NOSIZE) // no size change

&& ((m_dwStyle & CBRS_BORDER_ANY) != CBRS_BORDER_ANY))

return;


m_nDockBarID = nDockBarID;


// Force recalc the non-client area

m_bInRecalcNC = TRUE; //<---- Lock no coming again...

SetWindowPos(NULL, 0, 0, 0, 0,

SWP_NOSIZE | SWP_NOMOVE | SWP_NOZORDER |

SWP_NOACTIVATE | SWP_FRAMECHANGED);

m_bInRecalcNC = FALSE;

}
