class Qutepart(QPlainTextEdit):
'''Qutepart is based on QPlainTextEdit, and you can use QPlainTextEdit methods,
if you don't see some functionality here.
**Text**
``text`` attribute holds current text. It may be read and written.::
qpart.text = readFile()
saveFile(qpart.text)
This attribute always returns text, separated with ``\\n``. Use ``textForSaving()`` for get original text.
It is recommended to use ``lines`` attribute whenever possible,
because access to ``text`` might require long time on big files.
Attribute is cached, only first read access after text has been changed in slow.
**Selected text**
``selectedText`` attribute holds selected text. It may be read and written.
Write operation replaces selection with new text. If nothing is selected - just inserts text::
print qpart.selectedText # print selection
qpart.selectedText = 'new text' # replace selection
**Text lines**
``lines`` attribute, which represents text as list-of-strings like object
and allows to modify it. Examples::
qpart.lines[0] # get the first line of the text
qpart.lines[-1] # get the last line of the text
qpart.lines[2] = 'new text' # replace 3rd line value with 'new text'
qpart.lines[1:4] # get 3 lines of text starting from the second line as list of strings
qpart.lines[1:4] = ['new line 2', 'new line3', 'new line 4'] # replace value of 3 lines
del qpart.lines[3] # delete 4th line
del qpart.lines[3:5] # delete lines 4, 5, 6
len(qpart.lines) # get line count
qpart.lines.append('new line') # append new line to the end
qpart.lines.insert(1, 'new line') # insert new line before line 1
print qpart.lines # print all text as list of strings
# iterate over lines.
for lineText in qpart.lines:
doSomething(lineText)
qpart.lines = ['one', 'thow', 'three'] # replace whole text
**Position and selection**
* ``cursorPosition`` - cursor position as ``(line, column)``. Lines are numerated from zero. If column is set to ``None`` - cursor will be placed before first non-whitespace character. If line or column is bigger, than actual file, cursor will be placed to the last line, to the last column
* ``absCursorPosition`` - cursor position as offset from the beginning of text.
* ``selectedPosition`` - selection coordinates as ``((startLine, startCol), (cursorLine, cursorCol))``.
* ``absSelectedPosition`` - selection coordinates as ``(startPosition, cursorPosition)`` where position is offset from the beginning of text.
Rectangular selection is not available via API currently.
**EOL, indentation, edge**
* ``eol`` - End Of Line character. Supported values are ``\\n``, ``\\r``, ``\\r\\n``. See comments for ``textForSaving()``
* ``indentWidth`` - Width of ``Tab`` character, and width of one indentation level. Default is ``4``.
* ``indentUseTabs`` - If True, ``Tab`` character inserts ``\\t``, otherwise - spaces. Default is ``False``.
* ``lineLengthEdge`` - If not ``None`` - maximal allowed line width (i.e. 80 chars). Longer lines are marked with red (see ``lineLengthEdgeColor``) line. Default is ``None``.
* ``lineLengthEdgeColor`` - Color of line length edge line. Default is red.
**Visible white spaces**
* ``drawIncorrectIndentation`` - Draw trailing whitespaces, tabs if text is indented with spaces, spaces if text is indented with tabs. Default is ``True``. Doesn't have any effect if ``drawAnyWhitespace`` is ``True``.
* ``drawAnyWhitespace`` - Draw trailing and other whitespaces, used as indentation. Default is ``False``.
**Autocompletion**
Qutepart supports autocompletion, based on document contents.
It is enabled, if ``completionEnabled`` is ``True``.
``completionThreshold`` is count of typed symbols, after which completion is shown.
** Linters support **
* ``lintMarks`` Linter messages as {lineNumber: (type, text)} dictionary. Cleared on any edit operation. Type is one of `Qutepart.LINT_ERROR, Qutepart.LINT_WARNING, Qutepart.LINT_NOTE)
**Actions**
Component contains list of actions (QAction instances).
Actions can be insered to some menu, a shortcut and an icon can be configured.
Bookmarks:
* ``toggleBookmarkAction`` - Set/Clear bookmark on current block
* ``nextBookmarkAction`` - Jump to next bookmark
* ``prevBookmarkAction`` - Jump to previous bookmark
Scroll:
* ``scrollUpAction`` - Scroll viewport Up
* ``scrollDownAction`` - Scroll viewport Down
* ``selectAndScrollUpAction`` - Select 1 line Up and scroll
* ``selectAndScrollDownAction`` - Select 1 line Down and scroll
Indentation:
* ``increaseIndentAction`` - Increase indentation by 1 level
* ``decreaseIndentAction`` - Decrease indentation by 1 level
* ``autoIndentLineAction`` - Autoindent line
* ``indentWithSpaceAction`` - Indent all selected lines by 1 space symbol
* ``unIndentWithSpaceAction`` - Unindent all selected lines by 1 space symbol
Lines:
* ``moveLineUpAction`` - Move line Up
* ``moveLineDownAction`` - Move line Down
* ``deleteLineAction`` - Delete line
* ``copyLineAction`` - Copy line
* ``pasteLineAction`` - Paste line
* ``cutLineAction`` - Cut line
* ``duplicateLineAction`` - Duplicate line
Other:
* ``undoAction`` - Undo
* ``redoAction`` - Redo
* ``invokeCompletionAction`` - Invoke completion
* ``printAction`` - Print file
**Text modification and Undo/Redo**
Sometimes, it is required to make few text modifications, which are Undo-Redoble as atomic operation.
i.e. you want to indent (insert indentation) few lines of text, but user shall be able to
Undo it in one step. In this case, you can use Qutepart as a context manager.::
with qpart:
qpart.modifySomeText()
qpart.modifyOtherText()
Nested atomic operations are joined in one operation
**Signals**
* ``userWarning(text)``` Warning, which shall be shown to the user on status bar. I.e. 'Rectangular selection area is too big'
* ``languageChanged(langName)``` Language has changed. See also ``language()``
* ``indentWidthChanged(int)`` Indentation width changed. See also ``indentWidth``
* ``indentUseTabsChanged(bool)`` Indentation uses tab property changed. See also ``indentUseTabs``
* ``eolChanged(eol)`` EOL mode changed. See also ``eol``.
