Hello, searching in Google, I found this:

How do I disable the [ X ] close button on forms?  http://www.tek-tips.com/faqs.cfm?fid=7515

I tested on Lazarus 1.14-W7, and it works. But I affraid is only form windows.

i found answer:

Code: [Select]

procedure Tf_name.FormClose(Sender: TObject; var CloseAction: TCloseAction);
begin
  if b_close = false then begin
    CloseAction := caNone;
  end;
end;

You went around the problem by leaving the 'X' there, just not doing anything when clicking it. So it may be solved for you, but as a topic it is not, if someone in the future is looking for it.

Set Form's BorderStyle property to bsNone.

This way the Maximize and Minize buttons are gone too.
And, the form cannot be dragged.

bsNone is not necessary, at least not in LAZARUS 1.6.4 FPC 3.0.2...   
Yeah... I don't know if this works under Linux the same way and I don't know if this was always the case in any LAZARUS version...

At least on WINDOWS it works now...

I tried on my Ubuntu Mate, the close button cannot be hidden unless we set the form style to bsNone as suggested by Zoran, but bsNone will hide all the title bar so the form cannot be dragged. I think User137's suggestion is the best, but if the close button really needed to be hidden, you can try to set the form style to bsNone and use the trick as discussed in this thread:

My issue is that I want to hide tha Close button only and keep the minimize and maximize ones

The problem is that not every underlying widget set supports that E.g. GTK won't allow it. But in Windows it works. There's little Lazarus can do about GTK(+)(2)(3).
