MFC adds a tray for the application (right-click the tray and the pop-up menu)

Source code: http://download.csdn.net/detail/nuptboyzhb/4137784

1. Import the resource (. ico) format of a tray icon; resource ID is idi_icon1

2. In the initialization function of the Framework Program, initialize a struct of a tray icon

Notifyicondata
Yyicondata; // notifyicondata Structure

Notifyicondata. cbsize = sizeof (notifyicondata); // allocate space for the notifyicondata struct

// Assign values to parameters of policyicondata struct

Policyicondata. hwnd = m_hwnd; // window handle

Policyicondata. uid = idi_policyicon; // ID

Yyicondata. uflags = nif_message | nif_icon | nif_tip;

Yyicondata. ucallbackmessage = wm_addtrayicon; // the ID of the callback message. We need to add a user message ing for the ID of the callback message.

Notifyicondata. hicon = afxgetapp ()-> loadicon (idi_icon1); // load the tray icon

Wcscpy (policyicondata. sztip,
_ T ("Create a tray icon for the program "));

Shell_policyicon (nim_add, & policyicondata); // Load Tray Icon

Note: There are several variables worth attention in this step:

A. m_hwnd is the handle of the entire application window.

B. idi_policyicon is a constant defined by us. Add the following code to the header file:

# Define idi_policyicon 100 // Tray Icon ID

C. wm_addtrayicon is the identifier of the custom message and a constant;

# Define wm_addtrayicon wm_user + 101 // custom message

3. Add User message ing and message processing functions

1. Add a member function:

Afx_msg lresult onaddtrayicon (wparam, lparam );

2. Add message ing

On_message (wm_addtrayicon, onaddtrayicon) // Add message ing

Note: The first parameter is the user-defined message identifier, and the second parameter is the message response processing function.

3. onaddtrayicon

Lresult Class Name: onaddtrayicon (wparam, lparam)

{

If (wparam = idi_policyicon)// Create a tray icon

{

Switch (lparam) // Message Type

{

Case wm_lbuttondblclk: // double-click the left button

// Hide or display the internship window

// Afxgetapp ()-> m_pmainwnd-> showwindow (sw_hide); // hide the window

Break;

Case wm_rbuttondblclk: // right-click

{

Afxgetapp ()-> m_pmainwnd-> destroywindow (); // close the window

Break;

}

Case wm_rbuttondown: // right-click the tray and display the menu

{

Cmenu menu, * psubmenu; // The cmenu object to be used later

Cpoint point;

Menu. loadmenu (idr_popup_menu); // load the custom right-click menu

Psubmenu = menu. getsubmenu (0); // obtain the first pop-up menu

Getcursorpos (& Point); // obtain the current cursor position psubmenu-> trackpopupmenu (tpm_leftalign, point. X, point. Y, this );

Break;

}

}

}

Return 1;

}

4. Unload the tray.

When the application exits, uninstall

Notifyicondata
Notifyicondata;

Policyicondata. cbsize = sizeof (policyicondata );

Policyicondata. uflags = 0;

Policyicondata. hwnd = m_hwnd;

Notifyicondata. uid
= Idi_policyicon;

Shell_policyicon (nim_delete, & policyicondata); // unload the tray icon

 

 

The ucallbackmessage variable of the notifyicondata struct, which associates the user message response with the click and other messages of the tray. the ID of the trayIdi_policyiconIt is exactly the basis for the user message response to determine whether the message is delivered by the tray;

 

 

In multi-document or single-document-based applications, When you click the Minimize button, we can hide the interface;

Specifically, add an onsize () Message

Void cmainframe: onsize (uint ntype, int CX, int CY)

{

Cframewnd: onsize (ntype,

CX,
Cy );

If (ntype = size_minimized)

{

Showwindow (sw_hide); // hide the main window when minimized

}

// Todo: add the message processing program code here

}

The minimal tray of the dialog box is similar here, you can refer to: http://justtotry.blog.163.com/blog/static/446308122011622101427208/
