本文介绍如何在对话框中创建包含组合框的自定义工具栏，并设置按钮图标及大小，同时实现了对工具栏上按钮点击事件及组合框选择改变事件的响应。

一、Create the Toolbar with ComboBox on dialog

bool CPrjToolBarTestDlg::CreateToolBar() { CString str; CImageList img; //------------------------------------------------------------------------------------ //if(!m_tb.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC)) if(!m_tb.CreateEx(this)) { TRACE0("Failed to create toolbar/n"); return false; // fail to create; } m_tb.GetToolBarCtrl().SetButtonWidth(50, 50); m_tb.GetToolBarCtrl().SetExtendedStyle(TBSTYLE_EX_DRAWDDARROWS); m_tb.ModifyStyle(0, TBSTYLE_FLAT | TBSTYLE_TRANSPARENT); //-------------------------------------------------------------- //Set Buttons Count m_tb.SetButtons(NULL, 3); // set up toolbar button sizes m_tb.SetSizes(CSize(50,50), CSize(40,40)); //Set Button's Icon img.Create(IDB_bmpCOLDTOOLBAR, 22, 0, RGB(255, 0, 255)); m_tb.GetToolBarCtrl().SetImageList(&img); img.Detach(); img.Create(IDB_bmpHOTTOOLBAR, 22, 0, RGB(255, 0, 255)); m_tb.GetToolBarCtrl().SetHotImageList(&img); img.Detach(); //-------------------------------------------------------------- //Set each Button m_tb.SetButtonInfo(0, 0, TBBS_SEPARATOR, 150); m_tb.SetButtonInfo(1, ID_Back, TBSTYLE_BUTTON, 0); //str = "Back"; //m_tb.SetButtonText(1, str); m_tb.SetButtonInfo(2, ID_Refresh, TBSTYLE_BUTTON, 3); //str = "Refresh"; //m_tb.SetButtonText(2, str); m_tb.SetBarStyle(m_tb.GetBarStyle() | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_FIXED); //m_tb.GetToolBarCtrl().AddStrings("ssssssssssss/0"); //-------------------------------------------------------- //Add the ComboBox Control in the ToolBar RECT rectComboBox; rectComboBox.left = 0; rectComboBox.top = 0; rectComboBox.right = 150; rectComboBox.bottom = 350; m_cmb.Create(WS_CHILD | WS_BORDER | WS_VISIBLE | WS_VSCROLL | CBS_DROPDOWNLIST | CBS_AUTOHSCROLL, rectComboBox,&m_tb,ID_cmbFont); m_cmb.AddString("1111111/0"); m_cmb.AddString("2222222/0"); m_cmb.AddString("3333333/0"); //-------------------------------------------------------- RepositionBars(AFX_IDW_CONTROLBAR_FIRST,AFX_IDW_CONTROLBAR_LAST,0); //------------------------------------------------------------------------------------ return true; }

二、Response the message
1、Add the message map

BEGIN_MESSAGE_MAP(CPrjToolBarTestDlg, CDialog) //{{AFX_MSG_MAP(CPrjToolBarTestDlg) ON_WM_PAINT() ON_WM_QUERYDRAGICON() ON_COMMAND(ID_Back,OnBack) ON_COMMAND(ID_Refresh,OnRefresh) ON_CBN_SELCHANGE(ID_cmbFont,OncmbFontSelChange) //}}AFX_MSG_MAP END_MESSAGE_MAP()

2、Reponse the message

void CPrjToolBarTestDlg::OnBack() { MessageBox("CPrjToolBarTestDlg::OnBack: Back"); } void CPrjToolBarTestDlg::OnRefresh() { MessageBox("CPrjToolBarTestDlg::OnRefresh: Refresh"); } void CPrjToolBarTestDlg::OncmbFontSelChange() { int iIndex; CString str; //----------------------------------------- iIndex = m_cmb.GetCurSel(); if (-1 != iIndex) { m_cmb.GetLBText(iIndex,str); MessageBox(str); } }
