oven på hvad ?

For formens \"Formstyle\" property kan du angive \"StayOnTop\"

udklip fra Delphi help:

Determines the form’s style.

type TFormStyle = (fsNormal, fsMDIChild, fsMDIForm, fsStayOnTop);
property FormStyle: TFormStyle;

Description

Use FormStyle to get or set the form’s style. FormStyle is one of the following values:

Value    Meaning

fsNormal    The form is neither an MDI parent window nor an MDI child window.
fsMDIChild    The form is an MDI child window.
fsMDIForm    The form is an MDI parent window.
fsStayOnTop    This form remains on top of the desktop and of other forms in the project, except any others that also have FormStyle set to fsStayOnTop. If one fsStayOntop form launches another, neither form will consistently remain on top.

If the form is the main form of an MDI application, its FormStyle property must be set to fsMDIForm.

Note:    It is not advisable to change FormStyle at runtime.

Alternativt:

If AllwaysOnTop Then
  SetWindowPos(handle, HWND_TOPMOST, Left, Top, Width, Height, 0)
Else
  SetWindowPos(handle, HWND_NOTOPMOST, Left, Top, Width, Height, 0);


Delphi

Med den metode jeg angav er der ikke noget problem i at skifte flere gange mens programmet kører.  Som Delphi selv skriver i SJensens klip, så er det ikke smart at skifte FormStyle under runtime (hvorfor mon?).
