is_exist

is_exist(); - this function is used to check the existence of the interface to the window.

After testing, the function returns the result of its work to the script :

true – the interface to the window was received

false – it was not possible to find such a window

PHP example:

  windowinterface->".basename(__FILE__)." ";

//1
echo "1.Check the existence of the main visible window containing the name XWeb(human):";
$xweb = $window->get_by_text("XWeb");
echo $xweb->is_exist()."
";

//2
echo "2.Check the existence of the main visible window containing the name Ptych:";
$xweb = $window->get_by_text("Ptych");
if(!$xweb->is_exist())
echo "no such window 
";

//end
echo "
 
";

//Quit
$app->quit();
?>

xhe_host = "127.0.0.1:7010"
from xweb_human_emulator import *

# Start
echo("

# 1
echo("1.Check the existence of the main visible window containing the name XWeb(human):")
xweb = window.get_by_text("XWeb")
echo(xweb.is_exist(), "

# 2
echo("2.Check the existence of the main visible window containing the name Ptych:")
xweb = window.get_by_text("Ptych")
if not xweb.is_exist():
echo("no such window 
")

# end
echo("

app.quit()
