Create the logon screen

In the last version of the Rialto PHP lib, you can design your screen in a class. In this tutorial you will learn how to create a screen and how to print it.

Create a folder named : screens.

In this folder create a new file named : DefaultScreen.php. 

<?php
 
class DefaultScreen extends RialtoPHPScreen {
 
	public function doPrint($writer){
		return '';
	}
}
?>

Create a window

<?php
 
class DefaultScreen extends RialtoPHPScreen {
 
	public $DIV	= "document.body";
	public $WINDOW 	= "myWindow";
	public $WINDOW_TITLE = "My Title";
	public $ICON = "images/imgFenSimple/picto-gr_recherchepatients.gif";
 
	public function doPrint($writer){
		$out.= $writer->windowTag($this->WINDOW,$this->WINDOW_TITLE, $this->DIV);
		return $out;
	}
}
?>
