Custom Structuredtexteditor source code instant Check

In the previous section we customized the WTP structuredtexteditor feature, and this section will customize another feature feature for instant source verification. The so-called source of real-time verification, is in the user's editing process (not saved), for user-edited content changes to do real-time verification, and give users instant feedback related to the error or other types of message. In this section, we'll take the label's instant check as an example to demonstrate how to customize the WTP Structuredtexteditor's source-code just-in-time verification.

Before customizing, let's take a look at the WTP structuredtexteditor existing source code instant Check function:

We see that when we delete the </jsp:text>, WTP Structuredtexteditor's instant checksum gives the wrong hint. In fact, we are in many other editors, such as the Java source Editor, and so on, we can see a similar real-time verification function.

"Related content in JFace Text framework"

Frankly speaking, our source code edit corresponding control is isourceviewer, then this check also should be isourceviewer provided a service. The JFace Text Framework does provide the appropriate mechanism for real-time verification of source code, and we look at the corresponding interface and operating principle.
