c++ - Message-only window not receiving messages from tray icon -


I am trying to write a simple reusable class so that the functionality for the basic tray icon can be molded. This is my first "project" with C ++, and I'm having some problems: Message created for tray icon - only window does not receive any message in the icon tray And he has the right tooltip, but when I click on it, no message is sent in my invisible window.

To check that the function WindowProcedure I added a printf statement, and the output is that the build is called 4 times, but now more No, even though I click on the notification icon.

Why does not the tray icon get any message from my window?

This is what I wrote:

TrayIcon.h : 

  Square tray inkon {public: tray iacon (); ~ Trayicon (); Show zero (); /*...*/ fixed zero start (); Private: static LRESULT callback window precirer (HWW, UINT messaging, Varm vaporum, LAPRM LPARM); /*...*/};   
   TrayIcon.cpp  :  
  // static RIIER int tray icon: _ idcounter = 1; Zero TrayIcon :: Initialize () // This method is called only once {// trunction registers the square for window WNDCLASSEX wx = {}; Wx.lpfnWndProc = TrayIcon :: WindowProcedure; Wx.lpszClassName = TRAYICON_WINDOW_CLASSNAME; Wx.cbSize = sizeof (WNDCLASSEX); RegisterClassEx (& amp; wx); } // constructor tray econo :: trichon () {// a hidden message-window only HWND hWnd = CreateWindowEx (0, TRAYICON_WINDOW_CLASSNAME, "TrekonWindo", 0, 0, 0, 0, 0, hwmsmax, faucet, zero, Zero);); Set Window Longprints (HWW, GWLP_USRDATA, (Long) this); // makes the notification icon NOTIFYICONDATA icon; Memc (& amp; icon, 0, size (NOTIFYICONDATA)); Icon.cbSize = sizeof (NOTIFYICONDATA); Icon.hWnd = hWnd; Icon.uID = TrayIcon :: _ idCounter ++; Icon.uCallbackMessage = WM_TRAYICON; // Set up our invented Windows message icon.uFlags = NIF_MESSAGE; This- & gt; _iconData = Icon; } // shows the tray icon zero TrayIcon :: Show () {// ... Shell_NotifyIcon (NIM_ADD, & amp; this-> _iconData); } // Processes of message received from the hidden window for each icon LRESULT callback: Window processing (HWNH HWD, UINT messaging, VARAM use, LAPRM LPARM) {tray icon * icon = (tray icon *) GetWindowLongPtr (HWD, GWLP_USRDATA); Printf ("called the window process. \ N \ r"); Return DefWindowProc (hwnd, message, wParam, lParam); }   
 And in this way I use the class:  
  int main () {// creates a new tray icon TrayIcon :: Initialize ( ); Tray icon * icon = new tray (); Icon-> SettailTip ("Foo Tooltip"); Icon & gt; SetIcon (...); Icon & gt; Show (); // User Wait for input zero * tmp; Cin & gt; & Gt; Tmp; Return 0; }   
 Thank you for your time.   
 
 
 You want something like a message loop, do not block the call to do some input, try the canonical message loop. :  
  MSG msg; While (GetMessage (& msg, nullptr, 0, 0)) {translation message (& amp; msg); DispatchMessage (& amp; msg); }

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
