VC++ Example: ToolBar with ComboBox, add CComboBox to CToolBar

 
 By Zahirul Haque. 

Introduction

This article demonstrates an easy way to add a Combo box to a docking tool bar. I was needed to add a edit control to the toolbar for my dBase Explorer project. Although, I found some of the articles on it in the site, most of them are difficult to implement, and you need to add a lot of code or even a new class. This article shows how you can add a combo box to a toolbar only by adding a few lines of code.

In order to add a combo box to a toolbar, you need to declare a member variable type CComboBox to the CMainFrame class as shown below:

//
// Any source code blocks look like this
class CMainFrame : public CFrameWnd
{
	
protected: // create from serialization only
	CMainFrame();
	DECLARE_DYNCREATE(CMainFrame)

protected: // control bar embedded members
CStatusBar m_wndStatusBar;
CToolBar m_wndToolBar;
CComboBox m_comboBox;

...
};

You also need to create a place holder icon in the toolbar for the combo box. An Id should be assigned to the place holder icon by double clicking on it, for example, in my case ID_COMBO was assigned to the place holder. Then by calling the Create function, you create the combo box in the toolbar as shown below:

//
if(!m_comboBox.Create(CBS_DROPDOWNLIST | CBS_SORT | WS_VISIBLE |
		WS_TABSTOP | WS_VSCROLL, rect, &m_wndToolBar, ID_COMBO))
	{
		TRACE(_T("Failed to create combo-box\n"));
		return FALSE;
	}

The complete listing of the OnCreate function is given below:

Collapse
//
//
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
	if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
		return -1;
	
	if (!m_wndToolBar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP
		| CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) ||
		!m_wndToolBar.LoadToolBar(IDR_MAINFRAME))
	{
		TRACE0("Failed to create toolbar\n");
		return -1;      // fail to create
	}

	if (!m_wndStatusBar.Create(this) ||
		!m_wndStatusBar.SetIndicators(indicators,
		  sizeof(indicators)/sizeof(UINT)))
	{
		TRACE0("Failed to create status bar\n");
		return -1;      // fail to create
	}

	// TODO: Delete these three lines if you don't want the toolbar to
	//  be dockable
	CRect rect;
	int nIndex = m_wndToolBar.GetToolBarCtrl().CommandToIndex(ID_COMBO);
	m_wndToolBar.SetButtonInfo(nIndex, ID_COMBO, TBBS_SEPARATOR, 205);
	m_wndToolBar.GetToolBarCtrl().GetItemRect(nIndex, &rect);
	rect.top = 1;
	rect.bottom = rect.top + 250 /*drop height*/;
	if(!m_comboBox.Create(CBS_DROPDOWNLIST | CBS_SORT | WS_VISIBLE |
		WS_TABSTOP | WS_VSCROLL, rect, &m_wndToolBar, ID_COMBO))
	{
		TRACE(_T("Failed to create combo-box\n"));
		return FALSE;
	}
	m_comboBox.AddString("Toolbar Combobox item one");
	m_comboBox.AddString("Toolbar Combobox item two");
	m_comboBox.AddString("Toolbar Combobox item three");
	m_comboBox.AddString("Toolbar Combobox item four");
	m_comboBox.AddString("Toolbar Combobox item five");
	m_comboBox.AddString("Toolbar Combobox item six");

	m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);
	EnableDocking(CBRS_ALIGN_ANY);
	DockControlBar(&m_wndToolBar);
	return 0;
}
