Constructor Detail

JavaTextArea

public JavaTextArea(TextAreaDefaults defaults,
                    JavaEditor editor)

Method Detail

getJavaEditor

public JavaEditor getJavaEditor()

createPainter

protected JavaTextAreaPainter createPainter(TextAreaDefaults defaults)

Overrides:

createPainter in class PdeTextArea

getJavaPainter

protected JavaTextAreaPainter getJavaPainter()

processKeyEvent

public void processKeyEvent(KeyEvent evt)

Handles KeyEvents for TextArea (code completion begins from here). TODO Needs explanation of why this implemented with an override of processKeyEvent() instead of using listeners.

Overrides:

processKeyEvent in class JEditTextArea

fetchPhrase

protected void fetchPhrase()

Retrieves the current word typed just before the caret. Then triggers code completion for that word.

Parameters:

evt - - the KeyEvent which triggered this method

parsePhrase

protected static String parsePhrase(String lineText)

showSuggestion

protected void showSuggestion(DefaultListModel<CompletionCandidate> listModel,
                              String subWord)

Calculates location of caret and displays the suggestion pop-up.

hideSuggestion

public void hideSuggestion()

Hides suggestion popup

tweakRemoveListeners

public void tweakRemoveListeners()

startTweakMode

public void startTweakMode()

stopTweakMode

public void stopTweakMode()

updateInterface

public void updateInterface(List<List<Handle>> handles,
                            List<List<ColorControlBox>> colorBoxes)
