Constructor Detail

EditorKeyPressedAdapter

public EditorKeyPressedAdapter(WorkspaceCommands workspaceCommands,
                               JFrame frame,
                               org.fife.ui.rsyntaxtextarea.RSyntaxTextArea input,
                               JTextArea output)

Method Detail

public int getLineNumber(int position)

Returns the line number (starting at 0) of the current cursor position.

Returns:

toggleSelectionComment

protected String toggleSelectionComment(String selection)

                                   String example)

keyPressed

public void keyPressed(KeyEvent e)

NOTE

This is not just a text area, it is an RSyntaxTextArea which masks off various keystroked for itself. A symptom of this is if you attempt to use one of the (not well documented) reserved keystrokes, you will get mysterious enter key events as it tries to reformat (or whatever) the input area. So far the list of reserved keys are

• a -- select all
• c -- copy select to clipboard
• d -- delete current line
• j --(justify?)
• k -- beeps?
• v -- paste from clipbaord
• x -- cut selected to clipboard

Specified by:

keyPressed in interface KeyListener

Overrides:

keyPressed in class KeyAdapter

protected void doQuit(boolean forceQuit)

showHelp

protected void showHelp(String title,
                        String message)

Show's help for the selected area. Note that this allows for editing and copy paste to the main window (standard Swing dialog does not)

Parameters:

title -
