WebRunner Sample

WebRunner Sample is a viewer for accessing, reading, and navigating through various online informational sources. Information that users can browse might include such items as catalogs, technical documentation, weather reports, magazines, or dinner menus.

Information displayed in WebRunner Sample takes the form of hypertext that uses Hypertext Markup Language (HTML) document format. Within its text, this program embeds hypertext link components which enable the user to navigate to related information.

WebRunner Sample allows users to drag and drop its text and graphics to other documents that support editable text objects. For example, a user could browse through van Gogh's paintings and then choose to embed "Starry Night" in a newsletter that an art gallery uses to announce showings.

To implement these features, WebRunner Sample uses several frameworks and class libraries provided by the CommonPoint system. These include:

Document framework
Data Translation framework
Drag and Drop framework
Presentation framework
Text Editing framework

This program is specifically designed to show compound document behavior (such as embedding), how to integrate non-CommonPoint data formats such as Graphical Interchange Format (GIF) into CommonPoint documents, and how to provide a smooth interface to the Internet.

WebRunner Sample takes advantage of features provided by the World Wide Web library (LibWWW) developed at CERN (the European Laboratory for Particle Physics). Information about CERN is available through Mosaic` at

Information on HTML can be found through Mosaic at

What can users do? Commands, keys, and controls

Create a browser document that displays the default page (Taligent home page).

Create a browser to display a URL.

Navigate through online informational sources using hypertext links.

Drag and drop text and graphics from WebRunner Sample into documents that accept editable text objects and graphics objects.

Drag and drop hypertext links into documents that accept embedded components. WebRunnerApp

WebRunnerApp <URL>
For example, WebRunnerApp http://www.taligent.com

Click once with the mouse on embedded text that has an associated link symbol (downward pointing arrow).

Select a range of text from this program, then hold down the shift key and click on the selected range while dragging it to a new location. Release the mouse button at the location you want to integrate the information.

Select a range of text that includes an embedded link component and drag the text to another document. Release the mouse button at the location you want to integrate the text and the link component.
