setProperty (X emulator applet)

Syntax

Skip past command syntax or program codevoid setProperty(window, property, value)

Description

The setProperty method sets the value of a particular X property associated with an X window on the application server. If the X property doesn't already exist, this method creates it.

window is the name of the X window whose properties you're interested in. (This name is contained in the X window's WM_NAME X property.) Use an empty string ("") to specify the root window.

property is the name of the X property whose value this method sets.

value is the value you want to give to the specified X property.

This method can only set the values of X properties of type STRING. If you use the method to specify a value for an X property of another type, its type is changed to STRING.

Note Unlike the getProperty method, you don't need to register a property in order to change its value with setProperty.

Examples

Skip past command syntax or program code<SCRIPT LANGUAGE="JavaScript">

function setProperty() {
   var XEmulatorApplet = document.applets["Tarantella X Emulator"];

   // Get the value of the X Property text box

   XPropertyName = document.userInput.xproperty.value;

   // Get the value of the Value text box

   XPropertyValue = document.userInput.val.value;

   // Set the specified X property to the specified value

   XEmulatorApplet.setProperty("xterm", XPropertyName, XPropertyValue);
}

function getProperty() {
   var XEmulatorApplet = document.applets["Tarantella X Emulator"];
   var value = null;


   // Get the value of the X Property text box

   XPropertyName = document.userInput.xproperty.value;

   // Register an interest in the specified X property 

   XEmulatorApplet.registerProperty("xterm", XPropertyName);

   // Keep trying to retrieve the X property value.
   // It takes a finite amount of time to register the property. Until
   // the property is registered, getProperty() returns NULL.

   var loop=0;

   while (value == null) {
      value = XEmulatorApplet.getProperty("xterm", XPropertyName);
      loop++;
      if ( loop > 10000 ) break;
   }

   // Display the X property's value in the Value text box

   document.userInput.val.value = value;
}

</SCRIPT>

<FORM name="userInput">
 <p>X Property:
 <INPUT TYPE=text name=xproperty value=WM_COMMAND>

 <p>Value:
 <INPUT TYPE=text name=val value=null>

 <p><INPUT TYPE=button VALUE="Set X Property" onclick="setProperty()">
 <INPUT TYPE=button VALUE="Get X Property" onclick="getProperty()">
</FORM>

This example adds two text boxes and two buttons beneath the X emulator applet:

Note This example assumes the window name is xterm. You will need to change the code if you're using a different window name.

Add the code to the HTML document containing the X emulator applet (xde.html, in the sco/tta/standard webtop theme), after the TTAAPPLET declaration.
