In Delphi, the easiest way to make the form "Stayontop" is set to "FormStyle" attributes "fsStayont", but use this method, if the "FormStyle" property is set to other modes, window beat is flashing. In order to avoid this problem, here you can use the power of API to achieve the same functionality.
4.1 Setting the form as "Stayontop" style.
SetWindowPos (Form1.Handle
HWND_TOPMOST
Form1.Left
Form1.top
Form1.width
Form1.height
0);
The Form1 here is the name of your form
4.2, set the form to normal, non-TopMost style
SetWindowPos (Form1.Handle
HWND_NOTOPMOST
Form1.Left
Form1.top
Form1.width
Form1.height
0);
