System Tray Icons - Adding to your dialog application

Easy to implement system tray icon!

Sample Image - systray.jpg

Introduction

I write applications for my site Settlers.net and also to make things easier for myself at home. In one of my apps, I have wanted to include a system tray icon. Only problem being, the sys tray icon samples people wrote were confusing and didn't do what I want. I'm young and not exactly pro at programming yet. This tray icon code is different simply because upon starting the program, the icon is placed into the system tray. When you click hide, the whole program is minimized to tray.

Right, now down the code.

Let's do this!

Okay, on the main dialog you must make a button for the hiding command. Name this button IDC_HIDEAPP.

Add files traynot.cpp and traynot.h to your project.

Paste this into yourDlg.cpp:

void CYourDlg::OnHide()
{
  // Load icon onto taskbar tray
  m_pTray = new CTrayNot (this,WM_TRAY_NOTIFY,
  NULL,theApp.m_pIconList);
  m_pTray->SetState(IDR_MAINFRAME);
  m_bHidden = TRUE;
}

void CYourDlg::OnUnHide()
{
  ShowWindow (SW_RESTORE) ;
  m_bHidden = FALSE ;
  /////////////////////////////////////
  // Remove icon from taskbar tray
  if (m_pTray)
  {
     delete m_pTray ;
     m_pTray = NULL ;
  }
}

LONG CYourDlg::OnTrayNotify ( WPARAM wParam, LPARAM lParam )
{
  switch (lParam)
  {
    case WM_RBUTTONDOWN:
    {
       CMenu menu ;
       // Load and Verify Menu
       VERIFY(menu.LoadMenu(IDR_TRAY));
       CMenu* pPopup = menu.GetSubMenu (0) ;
       ASSERT(pPopup != NULL);

       // Get the cursor position
       POINT pt ;
       GetCursorPos (&pt) ;

       // Fix Microsofts' BUG!!!!
       SetForegroundWindow();

       ///////////////////////////////////
       // Display The Menu
       pPopup->TrackPopupMenu(TPM_LEFTALIGN |
       TPM_RIGHTBUTTON,pt.x, pt.y, AfxGetMainWnd());
       break ;
    }
    case WM_LBUTTONDBLCLK:
       //////////////////////////////////
       // Unhide our Window
       if (m_bHidden)
          ShowWindow (SW_RESTORE);
       //OnUnHide() ;
       break ;
  }
  return (0) ;
}

void CYourDlg::OnDestroy() 
{
  CDialog::OnDestroy();

  // Remove Icon from Tray
  if (m_pTray)
  {
    delete m_pTray ;
    m_pTray = NULL ;
  } 
}

void CYourDlg::OnTrayRestore() 
{
  // UnHide Application
  if (m_bHidden)
    ShowWindow (SW_RESTORE) ;
  m_bHidden = FALSE ;
}

void CYourDlg::OnHideapp() 
{
  //This will be the onclick for the hide button
  //in order to call that the app is minimised.
  theApp.HideApplication();
}

Add these to yourDlgs message map:

ON_MESSAGE(WM_TRAY_NOTIFY, OnTrayNotify)
ON_COMMAND(ID_TRAY_RESTORE, OnTrayRestore)
ON_BN_CLICKED(IDC_HIDEAPP, OnHideapp)

Add #include "TrayNot.h" to yourDlg.h. Add:

CTrayNot* m_pTray;
BOOL m_bHidden;

to your public call in yourDlg.h before yourDlgs standard constructor.

Add the following to your dialog's afx message maps.

afx_msg LONG OnTrayNotify ( WPARAM wParam, LPARAM lParam ) ;
afx_msg void OnTrayRestore();
afx_msg void OnHideapp();
afx_msg void OnHide();
afx_msg void OnUnHide();
afx_msg void OnDestroy();

In yourapp.cpp (Not yourdlg.cpp) add this just after #endif:

// Load Icons for Tray 
m_pIconList[0] = LoadIcon (MAKEINTRESOURCE(IDR_MAINFRAME));
m_pIconList[1] = LoadIcon (MAKEINTRESOURCE(IDR_MAINFRAME));
m_pIconList[2] = LoadIcon (MAKEINTRESOURCE(IDR_MAINFRAME));

In the yourapp.h (not yourdlg.h) add this to the public callback:

HICON m_pIconList[3];

After the last } down the bottom of this file, add this:

extern CYourApp theApp;

Open stdafx.h and add #define WM_TRAY_NOTIFY WM_APP+1000 after AfxCmn.h's include.

Now just add a menu using the resource add and name it IDR_TRAY. Add a restore command (ID_TRAY_RESTORE) and then you're done....

You may find that when you quit, the icon doesn't disappear. Use the destroy function and add delete m_pTray ; to it... Or you could just download my demo project and rip all the code from that?

Anyways, I hope this helped some of you. Vote for this, so I get a T-Shirt haha!

Tutorials I have written in the past, I have done so in a fashion that would enable even the newest of programmers to get a grasp on what is actually happening with the code I submit. I am looking at writing even more in the near future to further assist others as well as gain a better understanding myself of the code I end up with.

GeneralAfxGetApp()->HideApplication(); when initialising main wnd PinmemberIndrekSnt22-Dec-03 1:59 
I have windows XP and I want my program to automatically slip into tray without showing itself before.
 
HideApplication() works when I click on a button which triggers HideApplication() but not when I use it in BOOL CMyDlg::OnInitDialog(){
...
AfxGetApp()->HideApplication();
...
}
or in
LRESULT CMyDlg::WindowProc(UINT message, WPARAM wParam, LPARAM lParam){
...
if(message==WM_SHOWWINDOW){
AfxGetApp()->HideApplication();
}
...
}

 
How could I get the window closing when program initialised?
Confused | :confused:
