Delphi form without system menu but with close button

Question

By default, a form having BorderStyle=bsSizeable has a system menu (on the left) and a close button ('X', on the right). I want to get rid of the system menu and keep the close button.

The BorderIcons property lets me remove the system menu (via biSystemmenu), but now the close button is gone too.

Is there a way to do this?

Using Delphi XE

PS: it should be possible as far as Windows is concerned: IE8's "InPrivate Filtering settings" window is sizeable, has a close button and has no system menu.

Answer 1

BorderStyle := bsSizeToolWin does what you want, with a slightly different appearance of the X button.
