5.4 Viewing Event Information

The Status Bar

Select an event by double-clicking or right-clicking near its icon. Once the event is selected, a single vertical line appears on the view graph at the instant when the selected event occurred. The vertical line "snaps" to the nearest event. The name of the context where the event occurred, the event timestamp, the event type, and the event parameters appear in the view graph status bar, as shown in Figure 5-7.

The Show Event Dialog Box

There are two ways to bring up a Show Event dialog box similar to Figure 5-8:

Double-click on an event icon.

Right-click on an event icon, then click Show Event in the pop-up menu.

Figure 5-8: Show Event Dialog Box

When the Show Event dialog box appears, the lower portion contains information on the event you selected. It lists all the instrumented information for the event. In addition, WindView initializes the search fields in the upper portion of the dialog box with the event type, context, and object ID (if you are using AIL logging) of the selected event. You can search for similar events by clicking the Lock box to the right of each field you wish to set criteria for and then clicking Prev or Next.

You can also use the Show Event dialog box to search for other events. The Event and Context selection boxes have drop-down lists which include every event type and every context that occurs in the active log. Select the event type or the context name and number from the lists.

NOTE: If you wish to search for a user-defined event, you must know how you defined it, for example user10 or user99. Select user from the list and add the correct number to it.

The Legend Window

For online information on what each event icon and state stipple represents, click the Legend entry in either the WindView Help menu or the event pop-up menu (shown in Figure 5-3). Figure 5-9 shows the Legend window, which lists the event names with their associated icons. For detailed information, double-click on any event or stipple; this opens the Event Dictionary entry associated with that item.

The Event Dictionary

The Event Dictionary is available in hard copy (see B. Event Dictionary) and online. To view the online version, use one of the following methods:

Right-click on an event and select Help from the event pop-up menu.

Select Event Dictionary from the contents tab of the WindView Help menu.

Double-click on the event name in the Legend.

The Event Dictionary summarizes the information available about a specific event. It indicates what might have caused the event to occur, what may result from it, and what information is logged about that event at each level of logging.

NOTE: The Event Dictionary provides general entries for intEnt and user-defined events. However, in the view graph these events are of specific types. For example, you may have an intEnt-8 event, meaning that your application has passed control to interrupt level 8, or you may have an event called user10. You will not be able to call up the general Event Dictionary entry using the Help item in the event pop-up menu. Instead, use one of the other methods to reach the entry.
