switch class : Attach() method
Description
Attaches the handler to the event handling system.
Syntax
instance.Attach()
Arguments
None
Return value
None
Sample code
Suppose you have the following class definition.
| 1: | class handle |
| 2: | open method void LCHandler(dictionary dic) |
| 3: | ... // event handler code. |
| 4: | endmethod |
| 5: | endclass |
Usage of the Attach() method is as follows.
| 1: | browser b = new browser(); |
| 2: | handle h = new handle(); |
| 3: | switch sw = b.LoadCompleted(h,"LCHandler(dictionary)"); // The handler is automatically attached. |
| 4: | bool att = sw.IsAttach; // true; |
| 5: | sw.Detach(); // Detach the handler. |
| 6: | att = sw.IsAttach; // false; |
| 7: | sw.Attach(); // Re-attach the handler. |
Notes
If you call the handler assignment method as in the sample code, the handler is automatically attached to the event handling system.
If already attached, the method call is ignored.
The implementation of event handling has been changed in Cooker ver 3.0.3. This method was added as a result of that change.
