Fltk app in system tray?

hcker2000 · #1 24-Aug-2005, 02:22

Basicly I need to know if there is any way to hide all fltk windows with out it closing its self.

If so this would be a great help so I can put my app in the tray.

I'm using fltk 2.0 and win2k sp4

Yes, you can. FLTK merely leaves fltk::run() when all windows are closed. It does not call exit() or anything similar. But since you do not have a window anymore, you will not get any message handling either. I am sure that MSWindows has some mechanism for apps in the tray, however that is not built into FLTK.

As far as I can tell when all windows are hidden in fltk 2.0 the program closes and I can not seem to find a way around it.

If any one could post some example code that would be great.

resourcefile.rc

Code:

IDR_TRAYICON ICON "myicon.ico"

somwhere in somefile.c

Code:

  NOTIFYICONDATA icondata;
  int ret;
  
  icondata.cbSize = sizeof(icondata);
  icondata.hWnd = hWnd;
  icondata.uFlags = NIF_MESSAGE | NIF_TIP | NIF_ICON;
  icondata.uID = 0x1001; /* some random id as below */
  icondata.uCallbackMessage = 0x1001;
  icondata.hIcon = LoadIcon(NULL, IDR_TRAYICON);
  icondata.szTip = "This is some tip text";
  
  Shell_NotifyIcon(NIM_ADD, &icondata);

Of course there is no handling of the icon, but you might want to pick yourself up a copy of the win32 api docs. http://www.mingw.org has one.
