Pinnable ControlBar

Introduction

This article is based on the article CSizingControlBar - a resizable control bar by Cristi Posea. It implements a control bar that can be pinned.

Using the code

1. Include the following files in your project:

   scbarcf.cpp
   scbarcf.h
   sizecbar.h
   sizecbar.cpp
   scbarg.h
   scbarg.cpp
   
   PinDockBar.cpp
   PinDockBar.h
   AutoHideBar.cpp
   AutoHideBar.h
   DrawFrame.cpp
   DrawFrame.h
   

2. Add these lines to your stdafx.h (if the files are in a different directory, include the path - see the stdafx.h file in the samples):

   #define _SCB_REPLACE_MINIFRAME
   #include "sizecbar.h"
   #include "scbarg.h"
   #include "scbarcf.h"
   
   #include "PinDockBar.h"
   #include "DrawFrame.h"
   #include "AutoHideBar.h
   

3. Derive classes from CPinDockBar (you have an example in mybar.* files).
4. In mainfrm.h, include your class' header, i.e.

   #include "mybar.h"
   

   Then add member variables to CMainFrame, i.e.

       CMyBar m_MyBar;
       CMyBar2 m_MyBar2;
       CMyBar2 m_MyBar2_1;
   

5. In mainfrm.h, Add following macro in the CMainFrame class definition

   class CMainFrame : public CFrameWnd
   {
   //....    
       DECLARE_PINDOCK()
   };
   

6. In mainfrm.cpp, add following macro:

   IMPLEMENT_PINDOCK(CMainFrame)
   

7. In mainfrm.cpp, add following macro in the message map of the class:

   BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd)
   //...
       ON_PINDOCK_MESSAGES()
   END_MESSAGE_MAP()
   

8. Create the bar in CMainFrame::OnCreate(). Then set bar styles, enable it to dock... like any control bar. Using EnablePinDocking(..) instead of EnableDocking, i.e.

       EnablePinDocking(CBRS_ALIGN_ANY);
       //EnableDocking(CBRS_ALIGN_ANY);
   

9. Set your imagelist for the AutoHideBar array m_AutoHideBar[0..3]

       m_ImgList.Create(IDB_TAB, 16, 1, RGB(255,0,255));
       for(int i = 0;i < 4; i ++)
           m_AutoHideBar[i].SetImageList(&m_ImgList);
   

10. CPinDockBar is an abstract class, you need to implement two functions for your class:

    public:
        void AddToDrawBar(CAutoHideBar * pDrawBar);
        void RemoveFromDrawBar(CAutoHideBar * pDrawBar);
    

AddToDrawBar is called when a control sizing bar needs to move its child control(s) to side pane. RemoveFromDrawBar is called when a control sizing bar needs to take back its child control(s) from side pane.

The functions could be like this:

void CMyBar2::AddToDrawBar(CAutoHideBar * pDrawBar)
{
    CRect rt;
    GetClientRect(&rt);
    CString szStr;
    GetWindowText(szStr);
    pDrawBar->AddButton(szStr, DRAWBTNSTYLE_BTN, &m_List, 
        this, &rt, this, 0);
    
};

void CMyBar2::RemoveFromDrawBar(CAutoHideBar * pDrawBar)
{
    CRect rect;
    pDrawBar->RemoveButton(&m_List);
    pDrawBar->Shrink();
    pDrawBar->CalcLayout();
    pDrawBar->Invalidate();
    GetParentFrame()->ShowControlBar(this, TRUE, FALSE);

    GetClientRect(&rect);        
    m_List.MoveWindow(9,9, rect.Width() - 18, rect.Height() - 9 - 9);

};

LoadBarState() and SaveState() not implemented
