Set Web Viewer
Controls the specified web viewer.
Set Web Viewer [Object Name: “<object name>”; Action: <action>]
Click Specify to display the Set Web Viewer Options dialog box, where you can set the following options:
Object Name is the name of the web viewer to act upon. To assign an object name, select the web viewer, choose View menu > Inspector in Layout mode. Click Position, then enter a name for the object.
For Action, choose one of the following:
Reset resets the named web viewer to its originally specified web address. This action also clears this web viewer’s Back and Forward history.
Reload reloads the web page that the web viewer is displaying.
Go Forward goes forward one page, the same way a web browser does.
Go Back goes back one page, the same way a web browser does.
Go to URL lets you specify a new web address to load in the web viewer. The new web address is a calculation that you specify in the “Set Web Viewer - Go to URL” Options dialog box. In this script step, you cannot change whether the web viewer allows interaction, shows a progress bar or status messages, displays content in Find mode, or automatically encodes a URL. You can set these options only when you add or change a web viewer in Layout mode.
