Creating an Action
Use
An action is an incident that can be recognized by the application, for example, choosing a button. When you perform the action during runtime, the event assigned to the action occurs and triggers the corresponding event handler. For example, navigates to the next view when the user chooses the specified button.
When you create an action, the IDE generates an event handler called Action Event Handler for the action. This event handler stores the Java code that is executed when the action or event occurs. You can implement the event handler, as required.

Procedure
Creating the Action
...
1. In the Laptop UI Explorer, double-click the view element for which you want to create the action.
2. Choose the Actions tab.
3. Choose New.
4. Enter the information specified in the following table:
Field name |
Description |
User action and values |
Name |
Name of the new action |
Enter a name for the action, for example, Go. |
Text |
Label of the UI element to which you associate the action
|
Enter a name for the label.
If you enter the label Go and then assign the action to a button UI element, then the IDE assigns this label to the button. To enter a label of your choice, modify the text property of the button. |
Validation |
Identification of the action as a nonvalidating action |
Select this option if the action is a nonvalidating action. More information: Action Types |
Event Handler |
The code that the IDE executes when the application user triggers the action |
To use an existing event handler, select Use existing, and then select the required event handler. To generate a new event handler called onAction<Name of Action>, select Use default. |
Fire Plug |
The plug that is fired during runtime, when the application user triggers the action |
Select the outbound plug that you created.
● This is applicable only if you are creating the action in a view that contains an outbound plug. ● You can also create an outbound plug at this point, if required. To do this, choose New. The IDE generates the code to fire the outbound plug and includes it in the event handler. |
5. Choose Finish.
