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: 

    <?php $xhe_host = "127.0.0.1:7010";
 
//connect the object to control the emulator, if not already connected
if(!isset($path))
   $path = "../../../Templates/xweb_human_emulator.php";
require($path);
 
//Start
echo "<hr> <font color = blue> windowinterface->".basename(__FILE__)."</font> <hr>";
 
//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()."<br>";
 
//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 <br>";
 
//end
echo "<hr> <br>";
 
//Quit
$app->quit();
?>

    Python example: 

    # Additional paths
import sys
sys.path.insert(0, '../../../Templates PY/')
 
xhe_host = "127.0.0.1:7010"
from xweb_human_emulator import *
 
# Start
echo("<hr> <font color = blue> windowinterface.xxxxxxxxx </font> <hr>")
 
# 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(), "<br>")
 
# 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 <br>")
 
# end
echo("<hr> <br>")
 
# Quit
app.quit()
