Wait for Element until its exists

Hi,    Is there any specific method which I can use to wait until a certain element exists or loads up only then it goes to next step. As currently I am using .Delay() method which can fail if elem...

    If you do this

     

    (WBtn_ABC.Exists &&WBtn_ABC.VisibleOnScreen)

     

    WBtn_ABC.Exists can throw an error and stop the script if the object does not exist.

     

    I would do it this way:

     

    IF Aliases.Product.TransitionBox.PriceTicker.WaitAliasChild("WBtn_ABC", 10000).Exists THEN

        IF Aliases.Product.TransitionBox.PriceTicker.WBtn_ABC.VisibleOnScreen THEN

              'Do something because it is visible on screen

        END IF

ELSE

        Log.Error("The WBtn_ABC object does not exist")

END IF

    NOTE: The number 10000 means I would like to wait 10 seconds to check if the object exists. You can change it as required.

      I have now plenty of functions that waits for an enabled state, or disabled, or exists, or not, etc etc

      I use a delay (ms) and a an passes (integer)

      at every passes, I wait for the delay time. and they I check the property. when the test returns true, stop, exit.

       

      function WaitForExists(Alias: AliasObj; Time, Passes: integer): boolean;
      var
      i: integer;
      begin
      result:= false;
      for i:= 0 to Passes do
      begin
      Delay(Time);

      // note : put wathever you want in this test :

      if (Alias.Exists) then
      begin
      result:= true;
      exit;
      end;
      end;
      end;

      So, does it mean that it will always wait for 10 secs even the element is visible before that? Then whats the difference between using this method and delay ?

        The WaitAliasChild or the WaitChild methods wait only till the element is visible. The time we specify is the maximum amount of time we want it to wait.

         

        Which means if the element becomes visible in 1 second, it method will return the child object instantly, but if it becomes visible after 12 seconds, it'll fail because we gave 10 seconds as maximum wait time and the method would already have returned an object which will return false for the exists method.
