# Event Actions

Event Actions are used to initiate a specific action when a specified event occurs. In most cases, this feature is used to open a file when a display element is clicked. For example, a button in a PARCgraphics display can launch another PARCview display or any Windows-recognized file.

**Action:** The action to take when the event occurs. Select from the drop-down menu.

**Open Display:** Open a specified file. **Run Script:** Run a specified script when the event occurs. **Update:** Update a specified property value of an element in the display when the event occurs.

**Event:** The event that will cause the specified action to occur. Select from the drop-down menu. The options in the menu change depending on the selected element. Only one type of action can be taken for a given event.

By default, the list of events is filtered to the most commonly used. Check the box next to the event field to see more events.

**Event Action Definition:** After an action and a event are specified, an event action definition row appears. The options vary depending on the selected event and action. Click the red “X” to remove the event action definition.

**Open Display Action:** Specify a file to open. Click the ellipsis button ![](https://cdn.document360.io/59db2ca4-e512-446a-a143-a7c626447812/Images/Documentation/image127_001.png) to open the file browser. If Show New is checked, the file will open in a new window. Unchecking this option only applies if the specified file is another [PARCgraphics](/v1/docs/displays-parcgraphics) display. If unchecked, the graphic loads in the same window, and users can click back and forward browser-style buttons to navigate between displays.
