never show taskbar item for the form ???

[abmservice]

I am writing a simple program in windows at Lazarus and I want to hide applications from taskbar.
ShowInTaskbar: = stNever unfortunately does not work

I'm having the same problem with version 0.9.28.2 beta, which I believe is the latest release.
I'm setting the value ShowInTaskBar to StNever at design time but, when I run it, there it is, large as life, just to the right of the quick launch bar.

Argh!

Simon.

This works for me:

Code: [Select]

var
    h, p :thandle;
begin
    h := FindWindow('Window', PChar(Application.Title));
    p := GetParent(h);
    if h = Self.Handle then
    repeat
      h := FindWindowEx(p, h, 'Window', PChar(Application.Title));
    until (h = 0)  or  (h <> Self.Handle);
    ShowWindow(h, 0);
end;

    ShowWindow(h, 0);
end; 

where must i put it?

The form must be visible, for example on an OnPaint event handler.

Thank you, it works!

How can i make it on Linux?

[Blaazen]

ShowInTaskBar:=stNever; works in Linux (both GTK2 & Qt4) but border style must be BorderStyle:=bsNone;
Although form is still visible in list of windows when you are switching by Alt+Tab.

EDIT: It seems I was not right. ShowInTaskBar:=stNever; works regardless on BorderStyle or FormStyle.

  It's really interesting: it works on Linux? but it's doesn't work in Windows
