类似QQ与360软件,消息提示有两种。上下浮动、渐入渐出。
1、上下浮动提示框实现
机制,定时器响应上下浮动消息。
主要API:MoveWindow。
源码如下UpDownTipDlg.h、UpDownTipDlg.cpp。
UpDownTipDlg.h
- /*

- #pragma once
- // CUpDownTipDlg dialog
- class CUpDownTipDlg : public CDialog
- {
- DECLARE_DYNAMIC(CUpDownTipDlg)
- public:
- CUpDownTipDlg(CWnd* pParent = NULL); // standard constructor
- virtual ~CUpDownTipDlg();
- // Dialog Data
- enum { IDD = IDD_MCMSG_DLG };
- void ShowMsgWindow(CWnd* pParent, const CString& strTipInfo);
- protected:
- virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support
- virtual BOOL OnInitDialog();
- //响应关闭消息,删除对象
- virtual void OnCancel();
- virtual void PostNcDestroy();
- afx_msg void OnTimer(UINT_PTR nIDEvent);
- afx_msg void OnBnClickedOk();
- afx_msg void OnBnClickedCancel();

- private:

- };

- {

- SetTimer(POP_WINDOW, POP_ELAPSE, NULL);
- return TRUE;
- }
- void CUpDownTipDlg::InitDlgPosition()
- {
- CRect rectInit;
- GetWindowRect(&rectInit);
- RECT rect;
- SystemParametersInfo(SPI_GETWORKAREA, 0, &rect, 0);
- int cy = rect.bottom-rect.top;
- int cx = rect.right-rect.left;

- {
- case POP_WINDOW:
- {

2、渐入渐出提示框实现
机制,定时器响应淡入淡出消息。
主要API:AnimateWindow。
源码如下InOutTipDlg.h、InOutTipDlg.cpp。
InOutTipDlg.h
- /*
- *@brief 淡入淡出提示框
- *@date 2012-8-9
- */
- #pragma once
- // CInOutTipDlg dialog
- class CInOutTipDlg : public CDialog
- {
- DECLARE_DYNAMIC(CInOutTipDlg)
- public:
- CInOutTipDlg(CWnd* pParent = NULL); // standard constructor
- virtual ~CInOutTipDlg();
- // Dialog Data
- enum { IDD = IDD_MCMSG_DLG };
- void ShowMsgWindow(CWnd* pParent, const CString& strTipInfo);
- protected:
- virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support
- virtual BOOL OnInitDialog();
- //响应关闭消息,删除对象
- virtual void OnCancel();
- virtual void PostNcDestroy();
- afx_msg void OnTimer(UINT_PTR nIDEvent);
- afx_msg void OnBnClickedOk();
- afx_msg void OnBnClickedCancel();
- DECLARE_MESSAGE_MAP()
- private:
- void InitDlgPosition();
- private:
- CString m_strTipInfo;
- };
InOutTipDlg.cpp
- // MCMsgTipDlg.cpp : implementation file
- //
- #include "stdafx.h"
- #include "mcmsgtip_demo.h"
- #include "InOutTipDlg.h"
- const UINT_PTR BLAND_IN = 4;
- const UINT_PTR BLAND_OUT = 5;
- const UINT IN_ELAPSE = 1;
- const UINT OUT_ELAPSE = 5000;
- // CInOutTipDlg dialog
- IMPLEMENT_DYNAMIC(CInOutTipDlg, CDialog)
- CInOutTipDlg::CInOutTipDlg(CWnd* pParent /*=NULL*/)
- : CDialog(CInOutTipDlg::IDD, pParent)
- , m_strTipInfo(_T(""))
- {
- }
- CInOutTipDlg::~CInOutTipDlg()
- {
- }
- void CInOutTipDlg::DoDataExchange(CDataExchange* pDX)
- {
- CDialog::DoDataExchange(pDX);
- }
- BEGIN_MESSAGE_MAP(CInOutTipDlg, CDialog)
- ON_WM_TIMER()
- ON_BN_CLICKED(IDOK, &CInOutTipDlg::OnBnClickedOk)
- ON_BN_CLICKED(IDCANCEL, &CInOutTipDlg::OnBnClickedCancel)
- END_MESSAGE_MAP()
- // CInOutTipDlg message handlers
- void CInOutTipDlg::ShowMsgWindow(CWnd* pParent, const CString& strTipInfo)
- {
- m_strTipInfo = strTipInfo;
- Create(IDD, pParent);
- ShowWindow(SW_HIDE);
- }
- BOOL CInOutTipDlg::OnInitDialog()
- {
- CDialog::OnInitDialog();
- // TODO: Add extra initialization here
- SetDlgItemText(IDC_TIP_INFO, m_strTipInfo);
- InitDlgPosition();
- //消息渐入渐出效果
- SetTimer(BLAND_IN, IN_ELAPSE, NULL);
- return TRUE;
- }
- void CInOutTipDlg::InitDlgPosition()
- {
- CRect rectInit;
- GetWindowRect(&rectInit);
- RECT rect;
- SystemParametersInfo(SPI_GETWORKAREA, 0, &rect, 0);
- int cy = rect.bottom-rect.top;
- int cx = rect.right-rect.left;
- int nx = rect.right - rectInit.Width();
- int ny = cy - rectInit.Height();
- rectInit.MoveToXY(nx, ny);
- MoveWindow(rectInit);
- }
- void CInOutTipDlg::OnTimer(UINT_PTR nIDEvent)
- {
- RECT rect;
- SystemParametersInfo(SPI_GETWORKAREA,0,&rect,0);
- int cy = rect.bottom-rect.top;
- int cx = rect.right-rect.left;
- CRect rectTip;
- GetWindowRect(&rectTip);
- switch (nIDEvent)
- {
- case BLAND_IN:
- {
- KillTimer(BLAND_IN);
- AnimateWindow(1000, AW_BLEND);
- SetTimer(BLAND_OUT, OUT_ELAPSE, NULL);
- break;
- }
- case BLAND_OUT:
- {
- KillTimer(BLAND_OUT);
- AnimateWindow(1000, AW_BLEND|AW_HIDE);
- PostMessage(WM_CLOSE);
- break;
- }
- }
- CDialog::OnTimer(nIDEvent);
- }
- void CInOutTipDlg::OnCancel()
- {
- DestroyWindow();
- }
- void CInOutTipDlg::PostNcDestroy()
- {
- CDialog::PostNcDestroy();
- //窗口销毁时,删除该对象
- delete this;
- }
- void CInOutTipDlg::OnBnClickedOk()
- {
- OnOK();
- ::MessageBox(AfxGetMainWnd()->GetSafeHwnd(), _T("提示框的反馈-是"), _T("提示"), MB_OK);
- }
- void CInOutTipDlg::OnBnClickedCancel()
- {
- OnCancel();
- }
3、两种消息框调用
- void ShowTipWindow(const CString& strTipInfo)
- {
- CButton* pCheckBtn = (CButton*)GetDlgItem(IDC_CHECK_IO);
- if (BST_CHECKED == pCheckBtn->GetCheck())
- {
- //渐入渐出效果弹框
- CInOutTipDlg* pMsgWindow=new CInOutTipDlg();
- pMsgWindow->ShowMsgWindow(this, strTipInfo);
- }
- else
- {
- //上下浮动方式弹框
- CUpDownTipDlg* pMsgWindow=new CUpDownTipDlg();
- pMsgWindow->ShowMsgWindow(this, strTipInfo);
- }
- }
两个消息提示框,都封装了ShowMsgWindow接口,传入父窗口和待提示信息就可以了。
^_^这个调用方式有内存泄露现象,具体实现的时候,可以在对话框销毁时(virtual void PostNcDestroy()),提供一个回调删除接口。
