2  CAPTURING THE LOCATION OF A MOUSE CLICK EVENT USING THE EVENT OBJECT

Review Exercises

So far in this book, when you created and displayed an applet, you had a single window on the screen. This window was either Appletviewer or the browser you were using to display the applet. However, applets can create additional windows. Alt[r]

This class is used to manipulate buttons created in the Flash Professional interface, so you don’t have to rely solely on movie clips. Introduced in ActionScript 3.0, this class also allows you to create <[r]

Storing the Event ID if One Exists
Next, the event ID needs to be extracted, assuming it’s available. To find this value, use the event.target property again, but this time look for the sibling element with the name, event_id, and the[r]

The sample code contains a single event handler: Connect Button.Click Creates and opens a connection to a password-secured Microsoft Access database using the OLE DB .NET data provider..[r]

Not every event bubbles. For example, an onsubmit event propagates no further than the form object with which the event is associated. Events that do not bubble have their event object’s bubbles property set to false ; all others have the pr[r]

If you are entering this code, be sure to enter it into the ThisWorkbook object. Also, don’t change the name of the procedures. You can always spot an event procedure because it must begin with the name of the object that it is[r]

Similar to object and scene recognition, event classifi- cation is both an intriguing scientific question as well as a highly useful engineering application. From the scientific point of view, much needs to be done to understand how such complex and high level visual[r]

2.2. A state machine to define the component’s logic
State machine is a simple visual, yet mathematically rigorous, way of capturing behavior. In basic function blocks of IEC 61499, a state machine (called execution control chart, ECC for short) def[r]

Note how the value of the attribute is used as the body of the generated function, and note that the function is created so that the event parameter is available within the generated function.

Using Viewstate with List Controls
Not enabling viewstate is a common error newcomers make when using data binding and postbacks with the list controls in ASP.NET. If viewstate is not enabled, the list control will not m[r]

How It Works
After you get the name back from the text box, you have to use a function to compare the two values rather than use the basic Equal To operator. In this instance, you ’ re using the Compare method on

Understanding GUI Events
As mentioned earlier, the .NET Framework classes and controls used for building GUIs employ events extensively. You'll see and use GUI events on many occasions in the second half of this book. For example, the Button class derives from the[r]

You can use this event handler to trigger a script when your user has pressed a movie button or movie clip instance but released the mouse away from it, making this event handler useful [r]

Core Language Objects
It is often difficult for newcomers to programming — or even experienced programmers who have not worked in object-oriented worlds before — to think about objects, especially when attributed to “things” that don’t seem to have a physical presence. For example, i[r]

Before you get carried away with implementing different actions for single- and double-clicks on the same link, take a cue from the big GUI boys who design our desktops. Many users have difficulty accurately performing a double-click action, based on their computer[r]

counting rule, the permutation rules, and the combination rule can be used. The difference between a permutation and a combination is that for a permutation, the order or arrangement of the objects is important. For example, order is impo[r]

The day the music died ... the day events died, is when JavaScript ceased to exist. It would be a challenge to find a JavaScript program that doesn’t have an event handler. Events are the basis for interactivity a[r]
