## EditorTextField
|
|
|
|
Compared to
|
|
[Swing JTextArea](http://docs.oracle.com/javase/8/docs/api/javax/swing/JTextArea.html), the
|
|
*IntelliJ Platform's* editor component has a ton of advantages: syntax highlighting support, code completion, code folding and much more.
|
|
*IntelliJ Platform* editors are normally displayed in editor tabs, but they can be embedded in dialogs or toolwindows, too.
|
|
This is enabled by the
|
|
[EditorTextField](upsource:///platform/platform-impl/src/com/intellij/ui/EditorTextField.java)
|
|
component.
|
|
|
|
When creating an
|
|
[EditorTextField](upsource:///platform/platform-impl/src/com/intellij/ui/EditorTextField.java),
|
|
you can specify the following attributes:
|
|
|
|
* The file type according to which the text in the text field is parsed;
|
|
|
|
* Whether the text field is read-only or editable;
|
|
|
|
* Whether the text field is single-line or multiline.
|
|
|
|
A common use case for
|
|
[EditorTextField](upsource:///platform/platform-impl/src/com/intellij/ui/EditorTextField.java)
|
|
is entering the name of a Java class or package.
|
|
This can be accomplished with the following steps:
|
|
|
|
* Use
|
|
[JavaCodeFragmentFactory.getInstance().createReferenceCodeFragment()](upsource:///java/java-psi-api/src/com/intellij/psi/JavaCodeFragmentFactory.java)
|
|
to create a code fragment representing the class or package name;
|
|
|
|
* Call
|
|
[PsiDocumentManager.getInstance().getDocument()](upsource:///platform/core-api/src/com/intellij/psi/PsiDocumentManager.java)
|
|
to get the document corresponding to the code fragment;
|
|
|
|
* Pass the returned document to the
|
|
[EditorTextField](upsource:///platform/platform-impl/src/com/intellij/ui/EditorTextField.java)
|
|
constructor or its `setDocument()` method.
