List of onProcess() Examples

Examples of onProcess()

org.apache.click.Control.onProcess()
The on process event handler. Each control will be processed when the Page is requested.
ClickServlet will process all Page controls in the order they were added to the Page.
{@link org.apache.click.control.Container} implementations should recursivelyinvoke the onProcess method on each of their child controls ensuring that all controls receive this event. However when a control onProcess method return false, no other controls onProcess method should be invoked.
When a control is processed it should return true if the Page should continue event processing, or false if no other controls should be processed and the {@link Page#onGet()} or {@link Page#onPost()} methodsshould not be invoked.
Please note: a common problem when overriding onProcess in subclasses is forgetting to call super.onProcess(). Consider carefully whether you should call super.onProcess() or not, especially for {@link org.apache.click.control.Container}s which by default call onProcess on all their child controls as well. @return true to continue Page event processing or false otherwise
org.apache.click.control.Field.onProcess()
This method processes the page request returning true to continue processing or false otherwise. The Field onProcess() method is typically invoked by the Form onProcess() method when processing POST request.
This method will bind the Field request parameter value to the field, validate the submission and invoke its callback listener if defined. The code of this method is provided below:
```
 public boolean onProcess() { bindRequestValue(); if (getValidate()) { validate(); } registerActionEvent(); return true } 
```
@return true to continue Page event processing or false otherwise
org.apache.click.control.Form.onProcess()
Process the Form and its child controls only if the Form was submitted by the user.
This method invokes {@link #isFormSubmission()} to check whether the formwas submitted or not.
The Forms processing order is:
1. All {@link Field} controls in the order they were added
2. All {@link Button} controls in the order they were added
3. Invoke the Forms listener if defined
This method delegates validation to {@link #validate()} whilefile upload validation are delegated to {@link #validateFileUpload()}. @see org.apache.click.Context#getRequestParameter(String) @see org.apache.click.Context#getFileItemMap() @return true to continue Page event processing or false otherwise
org.apache.click.control.Submit.onProcess()
Process the submit event and return true to continue event processing.
If the submit button is clicked and a Control listener is defined, the listener method will be invoked and its boolean return value will be returned by this method.
Submit buttons will be processed after all the non Button Form Controls have been processed. Submit buttons will be processed in the order they were added to the Form. @return true to continue Page event processing or false otherwise
org.apache.click.control.TextArea.onProcess()

Examples of org.apache.click.control.TextArea.onProcess()

            public boolean onAction(Control source) {
                // When action is invoked, set flag to true
                return actionCalled = true;
            }
        });
        assertTrue(textArea.onProcess());


        // Fire all action events that was registered in the onProcess method
        context.executeActionListeners();


        assertTrue("TextArea action was not invoked", actionCalled);
