Checking until a window doesn't exist

Is there any way to check until a window doesn't exist. An inverse .WaitWindow()? Alternatively, is there a version of .Exists() that just returns bool? I've looked around forums and tried implementing this myself, but haven't found anything that works.

I'm using TC with Python. I set exceptions to not panic/exit early in TC, but .Exists() still does for some reason, even when caught.

I would avoid using the Exists method on the window object itself in this case. The issue is you'll take a performance hit of several seconds when the window no longer exists. That's because "Exists" waits for the full amount of time specified in your Auto-wait timeout set in the project properties. You could reset the Auto-wait time per Hassan_Ballan's suggestion.
However, I would suggest using WaitWindow with a loop something like below. As you can see, I included a counter/timer so that it doesn't get stuck in the loop if the window never closes.
Set myWindow = xxx.WaitWindow(wndClass, wndCaption, 1, 500) x = 0 While myWindow.Exists and x < 10 Delay 500 Set myWindow = xxx.WaitWindow(wndClass, wndCaption, 1, 500) x = x +1 Wend If Not myWindow.Exists Then Log.CheckPoint "Yippie! The window closed" Else Log.Message "Sad face. After waiting five seconds the window is still open" End If

You could use a while loop, This one is writen in JavaScript but should be about the same:
I added a check that after a few checks it returns

  WaitProperty method will pause execution until the specified object property achieves the specified value or until the specified timeout elapses. For example, waiting until the property value Visible becomes False.
  
  object.WaitProperty("Visible", "false", 30000);

Yes you can use the property exists described in https://support.smartbear.com/testcomplete/docs/reference/test-objects/members/common-for-all/exists-property.html?sbsearch=exists

Also as it would wait for the system default value when it no longer exist you need to change the value to lower setting, the following example is in JavaScript.

function Test()
{
//Capture default timeout value
var TimeoutValue;
TimeoutValue = Options.Run.Timeout;

//Set new default timeout value
Options.Run.Timeout = 500;
while(Aliases.browser.page.form.panel.Exists == true)
{
Delay(500);
}
Log.Message("Object no longer exists", "");

//Restore default timeout value
Options.Run.Timeout = TimeoutValue;
}
