Introduction

The CToolbarEx class supports basic customization (As in IE) with controls on it. Additionally it can hide the controls when the toolbar is docked vertically. This class uses the framework provided by ToolBarCtrl to do the customization of the Toolbar. It also supports Large Icons and Text on Buttons.

It uses a modified CCustomizeDialog class by Nikolay Denisov to provide extra options in the Toolbar customize Dialog.

I have hardcoded a few things in CCustomizeDialog to avoid resource dependences It also overrides CDockBar with CDockBarEx to provide 3D looks and overcome some docking bugs.

To use these in your project, do the following steps:

1. Add ToolBarEx.cpp and ToolBarEx.h in your Project.
2. Include ToolbarEx.h in MainFrame.h and Replace CToolBar with CToolBarEx in CMainFrame

   #include "ToolBarEx.h"
   . .
   
   // CToolBar      m_wndToolBar;
   CToolBarEx    m_wndToolBar;

3. In your OnCreate override in your CMainFrame class, when the creation of the Toolbar is done (including controls), call SetToolBarInfoForCustomization to set the Customization Data in the Toolbar. This function should be called after the creation of the toolbar, controls and dropdown is done.

   CRect rt(0,0,200,120);
   
   //Insert Control
   m_pComboBox =(CComboBox *) m_wndToolBar.InsertControl(
       RUNTIME_CLASS(CComboBox),_T(""),
       rt,ID_FIND,WS_VSCROLL|CBS_DROPDOWNLIST);
   m_pComboBox->AddString(_T("One"));
   m_pComboBox->AddString(_T("Two"));
   m_pComboBox->AddString(_T("Three"));
   
   //Add DropDown
   m_wndToolBar.AddDropDownButton(ID_OP,IDR_OP,TRUE);
   
   //Enable Customization
   m_wndToolBar.SetToolBarInfoForCustomization();

4. Restore the last saved data of the Toolbar

   //Restore State
   m_wndToolBar.RestoreState();

   Similarly you can also add SaveState in OnClose of the CMainFrame.

5. Then delete the buttons you do not want to show as default and call MarkDefaultState to set the default state of the toolbar. The default state is set when Reset button on the Customize Dialog Box is pressed.

   //Delete the button which do not need to shown initially.
   m_wndToolBar.GetToolBarCtrl().DeleteButton(
       m_wndToolBar.CommandToIndex(ID_CUSTOMIZE));
   
   
   // Mark the default state for reset
   m_wndToolBar.MarkDefaultState();

6. Call FrameEnableDocking instead of EnableDocking to use CDockBarEx instead of CDockBar.

   //     EnableDocking(CBRS_ALIGN_ANY);
   FrameEnableDocking(this,CBRS_ALIGN_ANY);

Member Functions & Data Members

CWnd* InsertControl(CRuntimeClass* pClass,LPCTSTR lpszWindowName,
    CRect& rect,UINT nID,DWORD dwStyle );

This function creates and inserts the control into the Toolbar and returns the window inserted. In rect parameter, pass only the width and height.

CWnd* InsertControl(CWnd* pCtrl,CRect& rect,UINT nID);

This function inserts the already created control into the Toolbar. In rect parameter, pass only the width and height.

BOOL AddDropDownButton(UINT nIDButton,UINT nIDMenu,BOOL bArrow=TRUE);

This function a button to a Dropdown with a menu attached to it. Set bArrow to TRUE if you want to show arrow next to it.

void SetToolBarInfoForCustomization();

This function sets the Customization information for the Toolbar. The Names used for the buttons in Customize dialog box are taken from the Tooltip of the Button. (String after Last '\n' of Prompt in Button Properties in Toolbar resource editing.) Call this function after the creation of the Toolbar is done. i.e. Controls, Dropdown have been added.

BOOL HasButtonText( int nID)

This function is used to determine whether the button has Text in "Selective Text on Right". At present it returns TRUE for all. Override this to provide new logic. nID is the command Identifier.

Minimum Requirements

It requires 5.80 version of the Commctl32.dll. It uses few features of 5.81 version, but they seem to work fine on 5.80 also. Please look at the Demo for full details.
