Hi list, I made some progress but I'm still a bit lost here. I managed to get Pharo to be headless in Win32, by hiding the window via NB as Igor suggested, plus suspending the UI process (UIManager default uiProcess suspend), which was the cause for the window to show up again after a fraction of a second, because of the refresh interval. However, now I can only close Pharo by killing the process manually, which is not very nice for the end user. So I figured I'd try to add an icon to the system tray with a single context menu entry for closing Pharo. This is what I'm doing, taken from MSDN<http://msdn.microsoft.com/en-us/library/windows/desktop/bb762159(v=vs.85).as...> : NBWin32Shell >> shellNotifyIcon: lpdata dwMessage: dwMessage <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^ self nbCall: #(bool Shell_NotifyIcon( DWORD dwMessage, PNOTIFYICONDATA lpdata )) module: #shell32 dwMessage is just a 0 (flag to create a tray icon), but lpdata needs to be a pointer to a struct of this form<http://msdn.microsoft.com/en-us/library/windows/desktop/bb773352(v=vs.85).as...> : typedef struct _NOTIFYICONDATA { DWORD cbSize; HWND hWnd; UINT uID; UINT uFlags; UINT uCallbackMessage; HICON hIcon; TCHAR szTip[64]; DWORD dwState; DWORD dwStateMask; TCHAR szInfo[256]; union { UINT uTimeout; UINT uVersion; }; TCHAR szInfoTitle[64]; DWORD dwInfoFlags; GUID guidItem; HICON hBalloonIcon; } NOTIFYICONDATA, *PNOTIFYICONDATA; So, my question is: how do I translate this into NB code? How does one define a struct and then pass its pointer to a function in NativeBoost? Thanks a lot for your help, I'm getting closer :) Bernat. p.s. Could the Windows API be any more convoluted and dev-unfriendly in any possible sense? 2013/11/4 Bernat Romagosa <tibabenfortlapalanca@gmail.com>
Hi!
Thanks Igor, that kinda worked! Pharo hides, but comes back after half a second or so. I'll keep digging, thanks! :)

Well, this should rather be:
handle :=NativeBoostWin32 squeakWindowHandle. window := NBWin32Window new value: handle; yourself. window hide.
or
window setWindowText: 'im a main window blablabla'.

You can try something like this:

:)
i didn't tested it since its been implemented, but i think it should work.

In this direction, I'm trying to call a function in the shell32.dll lib that apparently should let you minimize an app to the system tray, but I'm not having much luck... I guess I don't really understand what am I exactly doing.
This is what I found in the MSDN<http://msdn.microsoft.com/en-us/library/bb762159%28VS.85%29.aspx> :
BOOL Shell_NotifyIcon( _In_ DWORD dwMessage, _In_ PNOTIFYICONDATA lpdata );
So, I tried to translate this into Pharo as:
MyClass >> minimizeToTray: dwMessage data: lpData
<apicall: bool 'Shell_NotifyIcon' (dword PNOTIFYICONDATA) module: 'shell32.dll'>
But it won't let me save the method, reporting it's expecting an argument before PNOTIFYICONDATA.
I realize PNOTIFYICONDATA is not a primitive type, but I just don't know how to handle it... :(
