Ontologies such as syntax highlighting, and autocompletion. One column on
the left of the text editor contains line numbers and another contains
other contextual information such as whether a block of code has been
hidden/collapsed and can be displayed/expanded later. It also contains an
incremental search and an interface to pySUMO's settings so font size and
family can be changed at will.
Variables:
- syntax_highlighter: The syntax highlighter object for the text editor.
Methods:
- __init__: Initalizes the Object and the QPlainTextEdit
- commit: Notifies other Widgets of changes.
- show_autocomplete: Returns autocompletion choices.
- getWidget: returns the QPlainTextEdit
- numberbarPaint: Paints the numberbar
- searchCompletion: Asks QCompleter if a whole word exists starting with user input
- hideFrom: Starts hides all lines from the ()-block started by line
- insertCompletion: Puts the selected Completion into the TextEditor
