A project never needs to be closed explicitly, it gets closed when another project is opened or when the whole IDE is closed. Well, I think it does need to be closed from time to time. Namely: I want to be sure that all is closed before doing an svn update or git pull. Although many bugs have been fixed, still from time to time when you do an update of files on disk, Lazarus messes up and overwrites incoming changes. These things are unfortunately very hard to reproduce. I have reported several problems to Mattias, who promptly fixed them, but still it occurs under hard-to-reproduce circumstances. So, for safety, now I close the IDE, do the svn/git update, and then open the IDE. In Delphi (which has the same problem with SVN/git/...), I don't close the IDE, I just close all files. Luckily, the startup time of Lazarus is much shorter than Delphi's (the latter easily takes up to a minute to start). I could also temporarily open another project, but that is just as much a kludge as closing the IDE, worse yet, I can inadvertently change that project - and I know this from experience :( So, yes, I would actually prefer that 'Close all' does what it says on the tin, and really closes *all*. That I cannot do anything after this till I have opened the project again, is quite OK with me. It would even be OK if it just automatically started an empty new project after I did 'close all', as during startup. Just as long as all previously opened files are closed.

Well, this seems to make the program window maximized and this is not
what I want.
I want the video port only to be maximized
Meanwhile I found an example inside the PasLibVlc source package where
there is a function that seems to do what I wanted so I tried to put
it into my code.
However, it does not show any video on the resulting form, it is all
black...
And it does not return to the application's previous form either when
I hit a keyboard key. The application's main window in this case is
all black, only the title bar is not black
Here is the code of the button event that is supposed to maximize my
window (copied from the example and adjusted for proper player name):
procedure TfrmMain.SpeedButton1Click(Sender: TObject);
var
//Defined in unit FullScreenFormUnit from the example:
aFullScreenForm : TFullScreenForm;
oldL, oldT, oldW, oldH : Integer;
oldA : TAlign;
begin
MessageDlg('Press any key, to leave full screen mode',
mtInformation, [mbOK], 0);
oldL := vlcPlayer.Left;
oldT := vlcPlayer.Top;
oldW := vlcPlayer.Width;
oldH := vlcPlayer.Height;
oldA := vlcPlayer.Align;
if (oldA <> alNone) then vlcPlayer.Align := alNone;
aFullScreenForm := TFullScreenForm.Create(SELF);
aFullScreenForm.SetBounds(Monitor.Left, Monitor.Top, Monitor.Width,
Monitor.Height);
// PasLibVlcPlayer1.ParentWindow := aFullScreenForm.Handle;
{$IFDEF FPC}
LCLIntf.SetParent(vlcPlayer.Handle, aFullScreenForm.Handle);
{$ELSE}
{$IFDEF MSWINDOWS}
Windows.SetParent(vlcPlayer.Handle, aFullScreenForm.Handle);
{$ENDIF}
{$ENDIF}
vlcPlayer.SetBounds(0, 0, Monitor.Width, Monitor.Height);
aFullScreenForm.ShowModal;
vlcPlayer.SetBounds(oldL, oldT, oldW, oldH);
{$IFDEF FPC}
LCLIntf.SetParent(vlcPlayer.Handle, SELF.Handle);
{$ELSE}
{$IFDEF MSWINDOWS}
Windows.SetParent(vlcPlayer.Handle, SELF.Handle);
{$ENDIF}
{$ENDIF}
aFullScreenForm.Free;
if (oldA <> alNone) then vlcPlayer.Align := oldA;
end;

So far > I know of no one, who wants to rewrite all of this... Yes, the design is that the session (open files, positions, jumps, bookmarks, encoding, line ending, etc) are stored in the project. A package needs the settings of the project, e.g. macros like target OS/CPU. So if you want to edit a package or files without any project, the easiest way would be to implement a dummy/default project. Some functions and menu items must be disabled. And some error messages must be improved. The big questions are: Should the IDE restore the dummy session after a restart? If yes, then it must store the session and reload. And if yes, should a Close All wipe the whole session, e.g. file properties? Mattias -- ___ lazarus mailing list lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus

Maybe gnome API interfaces expose an api for the signals of the session manager. I doubt GTK handles these signals, and I don't think Lazarus uses the Gnome signals or the Gnome API. So I would attempt to connect to the gnome session manager using dbus. FPC has a DBUS client component, so this should not be too hard.
