If your app is not the foreground app, SetForegroundWindow will flash the
taskbar icon.

On a new project, drop a TTimer, paste this, run, and minimize your app.


procedure TForm1.Timer1Timer(Sender: TObject);
begin
  SetForegroundWindow(Form1.Handle);
end;


see msdn:
https://msdn.microsoft.com/en-us/library/windows/desktop/ms633539(v=vs.85).aspx

"An application cannot force a window to the foreground while the user is
working with another window. Instead, Windows flashes the taskbar button of
the window to notify the user."

You'll need the taskbar's handle which you can get from WidgetSet.AppHandle.


uses JwaWindows, InterfaceBase;

procedure TForm1.Button1Click(Sender: TObject);
var
  i: FLASH_INFO;
begin
  i.cbSize := sizeof(i);
  i.hwnd := WidgetSet.AppHandle;
  i.dwFlags := FLASHW_TRAY or FLASHW_TIMERNOFG;
  i.uCount := 0;
  i.dwTimeout := 0;
  FlashWindowEx(i);
end;

I have no clue how they do this - but would suspect that they might cycle 
through a number of images based on a timer

Subject: [Lazarus] Flashing task bat icon orange on Windows 7

​Hi,I am trying to work out how to flash the taskbar icon in Windows 7, like 
Skype does, pragmatically. I have googled, and the closest I found was 
FlashWindowEx, but that doesn't actually flash the icon, just the form window.
Any ideas?
Thanks
Richard​

​Hi,

Skype does, pragmatically. I have googled, and the closest I found was
FlashWindowEx, but that doesn't actually flash the icon, just the form
window.

Any ideas?
