24 Web Browser Display

Overview

The Web Browser Display (available since 2016.01) can display URLs that has been configured for a topology node in the topology.xml.

Configuration (up to Delft-FEWS 2018.02)

To use the HTML5 Display, configure it as <explorerTask> in Explorer.xml. For example:

		<explorerTask name="Web Browser Display">
			<iconFile>document.png</iconFile>
			<mnemonic>h</mnemonic>
			<taskClass>nl.wldelft.fews.gui.plugin.webbrowser.WebBrowserDisplay</taskClass>
			<toolbarTask>false</toolbarTask>
			<menubarTask>true</menubarTask>
			<accelerator>ctrl h</accelerator>
			<loadAtStartup>false</loadAtStartup>
		</explorerTask>

Configuration (Delft-FEWS 2018.02 onwards)

In Delft-FEWS 2018.02 (and later), a new package (Java Chromium Embedded Framework - JCEF) is taking care of launching this display. By default, this package is NOT installed and available through the Delft-FEWS libraries and need to be installed separately. Also some configuration adjustments are required to get this running if you were already using it in previous versions. If you want to add this display, you can find the complete instructions here as well.
