@ -23,18 +23,20 @@ This can be accomplished with the following steps:
* Call [`PsiDocumentManager.getInstance().getDocument()`](upsource:///platform/core-api/src/com/intellij/psi/PsiDocumentManager.java) to get the document corresponding to the code fragment; * 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. * Pass the returned document to the [`EditorTextField`](upsource:///platform/platform-impl/src/com/intellij/ui/EditorTextField.java) constructor or its `setDocument()` method.
E.g.:
```java ```java
PsiFile psiFile = PsiDocumentManager.getInstance(editor.getProject()).getPsiFile(editor.getDocument()); PsiFile psiFile = PsiDocumentManager.getInstance(project)
.getPsiFile(editor.getDocument());
PsiElement element = psiFile.findElementAt(editor.getCaretModel().getOffset()); PsiElement element = psiFile.findElementAt(editor.getCaretModel().getOffset());
PsiExpressionCodeFragment code = JavaCodeFragmentFactory.getInstance(editor.getProject()) PsiExpressionCodeFragment code =
.createExpressionCodeFragment("", element, null, true); JavaCodeFragmentFactory.getInstance(project)
.createExpressionCodeFragment("", element, null, true);
Document document = PsiDocumentManager.getInstance(editor.getProject()).getDocument(code); Document document =
PsiDocumentManager.getInstance(project).getDocument(code);
EditorTextField myInput = new EditorTextField(document, editor.getProject(), JavaFileType.INSTANCE); EditorTextField myInput =
new EditorTextField(document, project, JavaFileType.INSTANCE);
``` ```
