THE TOOLTIP CLASS An overview of the ToolTip class is provided in .NET Table 13.5. Note that a ToolTip object is not strictly speaking a control, although it is sometimes referred to as such. Normally, a single ToolTip object is used to create the tips for all controls in a single Form. Creating tool tips While it is certainly possible to assign tool tips for our MainForm controls in the MyPhotos project, this would not be a very exciting example. Since menu objects are not controls, we cannot assign tool tip text to our menu items. As we saw earlier in this chapter and in chapter 4, the ToolBar and StatusBar controls provide their own tool tip mechanism. That leaves the Panel object, which is only a single control. Instead, we will look to our now-famous MyPhotoAlbum library for a rich source of tool tip hungry controls. Figure 13.4 shows the PhotoEditDlg form with a tool tip displayed for the Date Taken text box.

All events are activated through a delegate Thus, the event delegate type defines the return type and signature for the event In this case, there are no parameters, but event parameters are allowed Next, an event class, called MyEvent, is created Inside the class, an event called SomeEvent is declared, using this line:

public event MyEventHandler SomeEvent;

Figure 13.4 The framework displays tool tip text just below the mouse cursor, which in most cases will not obscure the control s contents from view.

Notice the syntax The keyword event tells the compiler that an event is being declared Also declared inside MyEvent is the method OnSomeEvent( ), which is the method a program will call to signal (or fire ) an event (That is, this is the method called when the event occurs) It calls an event handler through the SomeEvent delegate, as shown here:

Let s crank up an Action-Result table and create a ToolTip object for this dialog. Once the tool tip exists, we can discuss how to associate specific messages with individual controls.

if(SomeEvent != null) SomeEvent();

Notice that a handler is called if and only if SomeEvent is not null Since other parts of your program must register an interest in an event in order to receive event notifications, it is possible that OnSomeEvent( ) could be called before any event handler has been registered To prevent calling on a null reference, the event delegate must be tested to ensure that it is not null Inside EventDemo, an event handler called Handler( ) is created In this simple example, the event handler simply displays a message, but other handlers could perform more meaningful actions In Main( ), a MyEvent object is created, and Handler( ) is registered as a handler for this event, by adding it as shown here:

Set the version number of the MyPhotoAlbum library to 13.4. ADD A TOOL TIP OBJECT TO THE PHOTOEDITDLG FORM Action 1 In the PhotoEditDlg.cs [Design] window, add a ToolTip object to the form. Set the (Name) for the tool tip to toolTipPhotos. Result The new object appears in the component tray below the form designer.

MyEvent evt = new MyEvent(); // Add Handler() to the event list evtSomeEvent += Handler;

As usual, the new object is defined within the PhotoEditDlg class and initialized in the InitializeComponent method.

15:

Notice that the handler is added using the += operator Events support only += and = In this case, Handler( ) is a static method, but event handlers can also be instance methods Finally, the event is fired as shown here:
