If your installer built with Setup Factory uses dialogs with custom sizes, you may notice that the dialogs won't show centered when you jump from a small dialog to a larger dialog or vice-versa. With this script, the new dialogs will always remain centered relative to the position of the former dialog.

How it works

• Place this into the Global functions:

   
  function getScreenCenter()
    local tScreenCenter = {};
    local tProps = Screen.GetProperties();
    local hWnd = tProps.WindowHandle;
    local tPos = Window.GetPos(hWnd);
    local tSize = Window.GetSize(hWnd);
   
    tScreenCenter.X = tPos.X + tSize.Width/2;
    tScreenCenter.Y = tPos.Y + tSize.Height/2;
    return tScreenCenter;
  end
   
  function setScreenCenter(tScreenCenter)
    local tProps = Screen.GetProperties();
    local hWnd = tProps.WindowHandle;
    local tPos = Window.GetPos(hWnd);
    local tSize = Window.GetSize(hWnd);
    local CurrentDialog = {};
   
    CurrentDialog.X = tPos.X + tSize.Width/2;
    CurrentDialog.Y = tPos.Y + tSize.Height/2;
    local x = tPos.X + (tScreenCenter.X - CurrentDialog.X);
    local y = tPos.Y + (tScreenCenter.Y - CurrentDialog.Y);
    Window.SetPos(hWnd, x, y);
  end
   

• Place this into each On Preload script of your dialogs:

   
  if (tScreenCenter ~= nil) then
    setScreenCenter(tScreenCenter);
  end
   

• Place this into each On Back and On Next scripts of your dialogs:

   
  tScreenCenter = getScreenCenter();
   

With this code, the center of each dialog will not move when you navigate in the screens of your installer.
