System menu fix for floating toolbar

Environment: ****** –>

Default system menu for standard MFC toolbar has maximize/minimize/restore ability. I didn’t like the
way the Maximized toolbar looked. Ben Summers and
Sushil Saxena already submited some ways to fix
MFC bars, however, I found another one:

MFC removes SC_SIZE from toolbar frame each time when it appears.

BOOL CMiniDockFrameWnd::Create(CWnd* pParent, DWORD dwBarStyle)
{
…
	CMenu* pSysMenu = GetSystemMenu(FALSE);
	pSysMenu->DeleteMenu(SC_SIZE, MF_BYCOMMAND);
…
}

The solution is a class derived from CMiniDockFrame with his own Create(…)

BOOL CFixedMiniFrameWnd::Create(CWnd* pParent, DWORD dwBarStyle)
{
	// set m_bInRecalcLayout to avoid flashing during creation
	// RecalcLayout will be called once something is docked
	m_bInRecalcLayout = TRUE;
	DWORD dwStyle = WS_POPUP|WS_CAPTION|WS_SYSMENU|MFS_MOVEFRAME|
		MFS_4THICKFRAME|MFS_SYNCACTIVE|MFS_BLOCKSYSMENU|
		FWS_SNAPTOBARS;
	if (dwBarStyle & CBRS_SIZE_DYNAMIC)
		dwStyle &= ~MFS_MOVEFRAME;
	DWORD dwExStyle = 0;
#ifdef _MAC
	if (dwBarStyle & CBRS_SIZE_DYNAMIC)
		dwExStyle |= WS_EX_FORCESIZEBOX;
	else
		dwStyle &= ~(MFS_MOVEFRAME|MFS_4THICKFRAME);
#endif
	if (!CMiniFrameWnd::CreateEx(dwExStyle,
		NULL, &afxChNil, dwStyle, rectDefault, pParent))
	{
		m_bInRecalcLayout = FALSE;
		return FALSE;
	}
	dwStyle = dwBarStyle & (CBRS_ALIGN_LEFT|CBRS_ALIGN_RIGHT) ?
		CBRS_ALIGN_LEFT : CBRS_ALIGN_TOP;
	dwStyle |= dwBarStyle & CBRS_FLOAT_MULTI;
	CMenu* pSysMenu = GetSystemMenu(FALSE);

	pSysMenu->DeleteMenu(SC_SIZE, MF_BYCOMMAND);
	pSysMenu->DeleteMenu(SC_MAXIMIZE, MF_BYCOMMAND);
	pSysMenu->DeleteMenu(SC_MINIMIZE, MF_BYCOMMAND);

	CString str;
	if (str.LoadString(AFX_IDS_HIDE))
		pSysMenu->ModifyMenu(SC_CLOSE,
			MF_BYCOMMAND|MF_STRING|MF_ENABLED, SC_CLOSE, str);
	// convert SC_RESTORE to ToggleDocking();
	if (str.LoadString(AFX_IDS_DOCK))
		pSysMenu->ModifyMenu(SC_RESTORE,
			MF_BYCOMMAND|MF_STRING|MF_ENABLED, SC_RESTORE, str);

	// must initially create with parent frame as parent
	if (!m_wndDockBar.Create(pParent, WS_CHILD | WS_VISIBLE | dwStyle,
		AFX_IDW_DOCKBAR_FLOAT))
	{
		m_bInRecalcLayout = FALSE;
		return FALSE;
	}
	// set parent to CMiniDockFrameWnd
	m_wndDockBar.SetParent(this);
	m_bInRecalcLayout = FALSE;
	return TRUE;
}

Then I add code to handle SC_RESTORE. This is not
necessary, but why not?

BEGIN_MESSAGE_MAP(CFixedMiniFrameWnd, CMiniDockFrameWnd)
	//{{AFX_MSG_MAP(CFixedMiniFrameWnd)
	ON_WM_SYSCOMMAND()
	//}}AFX_MSG_MAP
END_MESSAGE_MAP()
/////////////////////////////////////////////////////////////////////////////
// CFixedMiniFrameWnd message handlers
void CFixedMiniFrameWnd::OnSysCommand(UINT nID, LPARAM)
{
	switch (nID & 0xFFF0)
	{
		case SC_RESTORE:
			OnNcLButtonDblClk( HTCAPTION, CPoint(0,0));
			return;
	}
	Default();
}

Of course, MainFrame must know our new class

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
…
	m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);
	EnableDocking(CBRS_ALIGN_ANY);
	// Use our own class for miniframes
	m_pFloatingFrameClass = RUNTIME_CLASS(CFixedMiniFrameWnd);

…
}
