How is the Win32 API used in C++ to minimize a window to the system tray?


Tag : cpp , By : user186831

To fix this issue All you need is the Shell_NotifyIcon function. You ought to be able to work it out from MSDN, but if you need more help I'm sure there are a million places on the web that give samples. Now that you know the name of the API, web search will fill in the gaps.

I wish did fix the issue. I want to use in my wpf aplication notify icon (with .dll library in project http://www.codeproject.com/Articles/36468/WPF-NotifyIcon). , Try add an event handler for window messages
Command
namespace MyBasicFlyffKeystroke
{
    class ShowWindowCommand : ICommand
    {
        public void Execute(object parameter)
        {
            // Broadcast isn't a good idea but work...
            NativeMethods.PostMessage((IntPtr)NativeMethods.HWND_BROADCAST, NativeMethods.WM_SHOWME, IntPtr.Zero, IntPtr.Zero);
        }

        public bool CanExecute(object parameter)
        {
            return true;
        }

        public event EventHandler CanExecuteChanged;
    }
}
protected override void OnSourceInitialized(EventArgs e) {
    base.OnSourceInitialized(e);
    HwndSource source = PresentationSource.FromVisual(this) as HwndSource;
    source.AddHook(WndProc);
}

private IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled) {
    if (msg == NativeMethods.WM_SHOWME) {
        WindowState = WindowState.Normal;
    }
    return IntPtr.Zero;
}
public static readonly int HWND_BROADCAST = 0xffff;
public static readonly int WM_SHOWME = RegisterWindowMessage("WM_SHOWME");

[DllImport("user32.dll")]
public static extern int RegisterWindowMessage(string message);

[DllImport("user32.dll")]
public static extern bool PostMessage(IntPtr hwnd, int msg, IntPtr wparam, IntPtr lparam);

Electron.js How to minimize/close window to system tray and restore window back from tray?


Tag : javascript , By : CHeMoTaCTiC

Hope this helps I actually figured it out a long time ago but for folks who encounter the same problem here is one way you could achieve minimizing to tray and restoring from tray. The trick is to catch the close and minimize events.
var BrowserWindow = require('browser-window'),

var mainWindow = new BrowserWindow({
    width: 850,
    height: 450,
    title: "TEST",
    icon:'./icon.png'
});

mainWindow.on('minimize',function(event){
    event.preventDefault();
    mainWindow.hide();
});

mainWindow.on('close', function (event) {
    if(!application.isQuiting){
        event.preventDefault();
        mainWindow.hide();
    }

    return false;
});
var contextMenu = Menu.buildFromTemplate([
    { label: 'Show App', click:  function(){
        mainWindow.show();
    } },
    { label: 'Quit', click:  function(){
        application.isQuiting = true;
        application.quit();
    } }
]);

Minimize window to system tray

wish helps you There is no purely SDL2 way to do this, as Cody said, Shell_NotifyIcon is the function needed to create a notification area (system tray) icon.
The code I used to get the icon is
SDL_Window *window = SDL_CreateWindow("Test", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, 200, 200, SDL_WINDOW_HIDDEN);

SDL_SysWMinfo info;
SDL_VERSION(&info.version); 

NOTIFYICONDATA icon;
if (SDL_GetWindowWMInfo(window, &info))
{
    icon.uCallbackMessage = WM_USER + 1;
    icon.uFlags = NIF_ICON | NIF_TIP | NIF_MESSAGE;
    icon.hIcon = LoadIcon(NULL, IDI_INFORMATION);
    icon.cbSize = sizeof(icon);
    icon.hWnd = info.info.win.window;
    strcpy_s(icon.szTip, "Test tip");

    bool success = Shell_NotifyIcon(NIM_ADD, &icon);
}
SDL_Event e;
while (SDL_PollEvent(&e) != 0)
{
    switch (e.type)
    {
    case SDL_SYSWMEVENT:
        if (e.syswm.msg->msg.win.msg == WM_USER + 1)
        {
            if (LOWORD(e.syswm.msg->msg.win.lParam) == WM_LBUTTONDBLCLK)
            {
                SDL_ShowWindow(window);
                SDL_RestoreWindow(window);
            }
        }
        break;
    case SDL_QUIT:
        running = false;
        break;
    case SDL_WINDOWEVENT:
        if (e.window.event == SDL_WINDOWEVENT_MINIMIZED)
            SDL_HideWindow(window);
        break;
    }
}
