The extension API consists of a few function. For conveniance and further compatibility you should consider using the dhtml class, it is self documented and that’s the only API that’s not likely to change. Additionnaly it adds a few functionnality that you will need. You can find some examples in the wiki to get you started.

Create a DHTML window. It is initialy hidden.

Get the id of the DHTML window. That’s the id in the object returned by dhtml_get_event.

“Set” a property on a window. For the complete list see the table below

Return an object representing an event. Base of a run loop. If $wait=1 wait (sleep) until an event occurs. If $wait=0 returns false if no pending event since the last call.

Return the HWND1) of the current window.

Return an object containing the destop size (sx & sy members).

<?
$obj= dhtml_get_desktop_size();
var_export($obj);
?>

class stdClass {
  public $sx = 1400;
  public $sy = 1050;
}

Add an icon in the ‘Windows Notification Area’ also called ‘The Tray’.

• $id is the id of the tray (user defined)
• $tip is the ToolTip text
