catch error then perform specific task

[sean_ng]

Hi,

during playback i get this error :

There was an attempt to perform an action at point (X, Y) which is transparent or out of the window bounds.

i know what is causing this error :

because my web page have scroll bar and test complete is trying to click on object with is hidden, if i manually drag the scroll bar to show the object, then the error is gone.

what i want to do :

i would like to catch this error by using an if,else script. If this error happen then i run a script to move the scroll bar

what i did :

i tried using 'try .. catch ..' but it does not work.

try
{
   obj.click();
}
catch (e)
{
  Log.Error(e.description + "Specific Text");
  //execute script here
}

how can i catch the error and then perform a specific script to move the scroll bar ?

This is because the type of error raised is not a code exception but an operation exception with the "click" action.  These are not caught by try/catch.

Suggestion.  In your code for doing the object click, before the click, do a check for VisibleOnScreen. If VisibleOnScreen is false, then call obj.scrollIntoView(true).  This will scroll the web page to the component before the click.

hi tristaanogre,

Thank you for your reply.

your suggestion work well for me

below is the code i use, which is actually from AlexKaras

if (!obj.VisibleOnScreen) {

    obj.scrollIntoView(true);

    if (!obj.VisibleOnScreen) {

        obj.scrollIntoView(false);
    }
}

obj.Click();

I have the same issue but in a Windows app rather thana web page

Aliases.MyApp.HwndSource_MainWindow.MainWindow.m_NodeControl.ExpandItem(("|[2]"));
Aliases.MyApp.HwndSource_MainWindow.MainWindow.m_NodeControl.Refresh();
Aliases.MyApp.HwndSource_MainWindow.MainWindow.m_NodeControl.DblClickItem("|[2]|[0]");

The third line craters if the tree view is scroll off the screen so node 2 is not visible

I can't call is visible on the NodeControl as it always is

How do I ensure node 2 is visible ?

Scratch the above - I just call collapse on each branch and it comes into view

[tristaanogre]

Alternatively, you could check the VisibleOnScreen property.  If it is false, execute a page down or some other scroll event to bring the component to be visible on screen.

Yeah that didn't work cos the tree control is visible but that partcular node might not be so wasn't sure how to call is visible on a node?

Hi,

.VisibleOnScreen is a generic property added by TestComplete to any valid object (i.e. that one with .Exists property been set to true) and thus can be checked regardless of whether or not the object is visible on the screen:

if (<control>.VisibleOnScreen)

  ...

else

  ...

Actually, for standard Windows controls, TestComplete puts them in view automatically if the control is out of view. So, in general, the

<parent>.m_NodeControl.DblClickItem("|[2]|[0]");

line should work without any tweaks.

But custom controls may not implement all required functionality and thus require either manual scrolling (like suggested by Robert) or some other actions to make control visible on screen (like you did).
