// call "RepositionControls()" if you have added one or more controls
// and want to add more buttons/controls.
// This function will automatically be called for controls when calling
// CtrlReplace() and CtrlInsert().
void    RepositionControls();

// Recalculate the size of the toolbar and recalculate the
// layout of its parent.
// There should be no need to call this method from outside
// the toolbar.
void&nbsp;&nbsp;&nbsp; RecalcLayout();</FONT></TT></PRE>
There is no must to add controls with either CtrlInsert() or CtrlReplace().
You can do it in a more traditional fashion too and the toolbar still works
(i.e. it takes care of all its children, regardless of the way of insertion).
So there is no need to change your existing code. You should call RepositionControls()
by yourself, if you add more controls in another way than the prefered
one.

<P>You might add a combo-box in the following way (assuming your toolbar
resource includes a button with the id IDC_COMBOBOX, that is to be replaced
by the control):
<PRE><TT><FONT COLOR="#990000">// ...
// replace a button by a CComboBox-control on the toolbar
DWORD dwComboStyle = WS_VSCROLL|CBS_AUTOHSCROLL|CBS_DROPDOWN|CBS_HASSTRINGS;
CComboBox * pBox = (CComboBox*) m_wndToolBar.CtrlReplace(
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; RUNTIME_CLASS(CComboBox),&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // insert control of type CComboBox
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; IDC_COMBOBOX,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // id of the button that is to replace with the control
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; dwComboStyle&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // style bits
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; );
if( pBox ) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; pBox->AddString(TEXT("Line 1"));
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; pBox->AddString(TEXT("Line 2"));
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; pBox->AddString(TEXT("Line 3"));
}
// ...</FONT></TT></PRE>
As you can see, adding a control is an easy task.

<P>If you plan to use other types of controls (other than CComboBox or
CEdit), you have to derive a class from this type and to implement the
DECLARE_DYNCREATE macro and to overload the following methods:
<BR><FONT COLOR="#990000">virtual BOOL Create( LPCTSTR lpszClassName, LPCTSTR
lpszWindowName, DWORD dwStyle, const RECT&amp; rect, CWnd* pParentWnd,
UINT nID, CCreateContext* pContext = NULL);</FONT>
<BR>and
<BR><FONT COLOR="#990000">virtual void PostNcDestroy();</FONT>

<P>Lets say you plan to insert a static text into the toolbar:
<BR>Create a new class using class-wizard to create a class derived from
CStatic.
<BR>Use class-wizard or class-view to overload the 2 virtual methods described
above.
<BR>The result should look like this (assuming you have named the class
"CText"):
<PRE><TT><FONT COLOR="#990000">/////////////////////////////////////////////////////////////////////////////
// CText window

class CText : public CStatic
{
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; DECLARE_DYNCREATE(CText);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // &lt;&lt;== YOU HAVE TO INSERT THIS

// Construction
public:
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; CText();

// Attributes
public:

// Operations
public:

// Overrides
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // ClassWizard generated virtual function overrides
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //{{AFX_VIRTUAL(CText)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; public:
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; virtual BOOL Create(LPCTSTR lpszClassName, LPCTSTR lpszWindowName, DWORD dwStyle, const RECT&amp; rect, CWnd* pParentWnd, UINT nID, CCreateContext* pContext = NULL);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; protected:
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; virtual void PostNcDestroy();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //}}AFX_VIRTUAL

// Implementation
public:
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; virtual ~CText();

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Generated message map functions
protected:
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //{{AFX_MSG(CText)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // NOTE - the ClassWizard will add and remove member functions here.
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //}}AFX_MSG

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; DECLARE_MESSAGE_MAP()
};</FONT></TT></PRE>
In the implementation file you have to fill out the 2 overloaded methods:
<PRE><TT><FONT COLOR="#990000">IMPLEMENT_DYNCREATE(CText, CStatic); // &lt;&lt;== DO NOT FORGET THIS

BOOL CText::Create(LPCTSTR lpszClassName, LPCTSTR lpszWindowName, DWORD dwStyle, const RECT&amp; rect, CWnd* pParentWnd, UINT nID, CCrea

{
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return CWnd::Create(TEXT("STATIC"), TEXT("text control"), dwStyle|SS_LEFT, rect, pParentWnd, nID);
}

void CText::PostNcDestroy()&nbsp;
{
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; delete this;
}</FONT></TT></PRE>
That's all you have to do.
<BR>The proceeding with other types of controls is similar.

<P>Now you can insert such a control like follows:
<PRE><TT><FONT COLOR="#990000">int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // ...
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; m_wndToolBar.CtrlInsert(
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; RUNTIME_CLASS(CText),&nbsp;&nbsp; // the control's runtime class
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; CRect(-100, -22, 0, 0), // width is 100, height is 22
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; IDC_TEXT,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // control's ID
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 2&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // insert before button with index 2
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; );
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // ...
}</FONT></TT></PRE>

buttons that are checked <B>and</B> disabled are now looking ok</LI>

<LI>
don't draw a gripper if the bar is not dockable</LI>

<LI>
do not adjust space for gripper in "classic" mode</LI>

<LI>
give the bar itself a real 3D look (as in Office or DevStudio) (see images

<LI>
some minor code improvements</LI>

<BR>Old style 3D look of a toolbar.

<P><IMG SRC="NewStyleBorderLook.jpg" NOSAVE HEIGHT=186 WIDTH=472>
<BR>New style (as in Office or DevStudio).

<P>To enable the new 3D style you have to exchange the call to EnableDocking()
in your CMainFrame's OnCreate() method with a call to FrameEnableDocking():

Since my commercial projects have a higher priority than my hobby projects,
I don't have enough time to complete the persistence and customization
of the toolbar in a reasonable time. I'm looking for someone, who wants
to help me completing this. I have a somewhat more advanced version of
the class, that implements some aspects of these issues (send me mail to
get the source and see the images below). Both these problems got more
complex than I expected ...

<P><IMG SRC="ContextMenu.jpg" ALT="Context Menu" NOSAVE HEIGHT=146 WIDTH=212>
