[Solved] Program losing focus action
« on: August 06, 2020, 01:04:20 am »
Is there a function in lazarus that can check if my application/program loses it focus.
A.k.a. when I switch to another program the main form must be set to fsNormal instead of fsStayOnTop

Next time I must search this forum first before asking a question.

This is almost the solution.
But usually I have 2 forms on top.
How can I determine which form has the property fsStayOnTop so that I can reset them to that property

Remove fsStayOnTop:
Code: Pascal  [Select][+][-]
  1. var
  2.   I: Integer;
  3. begin
  4.   for I := Screen.FormCount - 1 downto 0 do
  5.   begin
  6.     if (Screen.Forms[I].FormStyle = fsStayOnTop) then
  7.     begin
  8.       Screen.Forms[I].Tag := -1; //remember which form has fsStayOnTop
  9.       Screen.Forms[I].FormStyle := fsNormal;
  10.     end;
  11.   end;

Restore fsStayOnTop:
Code: Pascal  [Select][+][-]
  1. var
  2.   I: Integer;
  3. begin
  4.   for I := Screen.FormCount - 1 downto 0 do
  5.   begin
  6.     if (Screen.Forms[I].Tag = -1) then
  7.     begin
  8.       Screen.Forms[I].Tag := 0;
  9.       Screen.Forms[I].FormStyle := fsStayOnTop;
  10.     end;
  11.   end;
