Developer Tip
Creating a DRP File

The Droplets .drp file is a small text file generated whenever a Droplet application is downloaded onto a client desktop. It gives the end-user's Client essential information like the name of the application and the location of the server-side application logic.

The DRP file consists of a series of parameter names and values. A set of pre-existing parameters must be included in every DRP file; you can also create your own parameters as necessary.

Parameters:

address: the location of the UI Server to which the Client should speak. Can be an IP address or a URL.

calc: the application name as registered with the UI Server.

height: the height in pixels of the application window.

icondata: a block of binary text formatted as text, defining the appearance of the application's desktop icon.

imagedir: the URL location of the application's skin files.

port: the port through which the client should contact the server (usually 8192).

title: the text that appears in the application's title bar.

width: the width in pixels of the application window.

mainpaneloff: boolean, determining whether or not the client waits until all components are loaded before presenting the application GUI. Looks more professional if you indicate true.

In addition to the DRP settings above, the "vars" parameter allows you to create custom DRP parameters as necessary for your Droplet application. Perhaps, for example, you need to uniquely identify one instance of the Droplet (as you might with our online photo album, Droplets Picture Share). In this event, you can simply create a new parameter name and assign it a value based on your DRP-generating script's logic.
