International Pacific Halibut Commission IPHC Widgets Widgets are a type of graphical user interface (GUI) that can be used to display information changeable by the user, such as a window or a text box. One of the advantages of a widget is to provide a single interactive tool to manipulate data, specify data inputs, model characteristics and view results. The International Pacific Halibut Commission developed two Widgets (Graphical User Interface) for the 2008 IPHC Biomass Apportionment Workshop held in Bellevue on September 4, 2008. This document describes how to install and use the second release of the widget developed to illustrate the effects of fishing, migration and different apportionment methods on the distribution and status of halibut from IPHC regulatory areas 4A to 2A. This widget version was used during the Biomass Apportionment Workshop II in Seattle on April 29-30, 2009. Installation This widget was developed with Visual Basic for Applications and use Microsoft Excel only to generate output graphs. The only requirement to use them is to have Excel (2003, 2007) installed in your computer. For the widgets to run properly you need to do the following steps: 1) Open Microsoft Office Excel 2) Go to “Tools” > “Options” > “Security” > “Macro Security” and set the security level to “Medium” 3) Close Microsoft Office Excel Now you can install the widget by opening the following installation file: The installation steps are basically the same we used for the widgets on the first apportionment workshop, below it is illustrated the steps for installing the new release. The selected option for the default installation is highlighted.
