 changedDiffText

 changedDiffText: something

 changedLines

 changedLines: something

 codeView

 contents: text

(comment from inherited method)
replace the whole contents by something new.
this is not undoably, unless you care for yourself.
See replaceContentsWith:newContents for an undoable version of this

 contents: text clear: clearPrevious

 deletedLines

 deletedLines: something

 diffMode

 diffMode: something

 emptyLines

 emptyLines: something

 fontAscent

(comment from inherited method)
answer the ascent of the current font on the current device

 insertedLines

 insertedLines: something

 listOriginal

 originDiffText

 originDiffText: something

 colorChanged

 colorDeleted

^ Color pink

 colorInserted

 list: aCollection expandTabs: expand scanForNonStrings: scan includesNonStrings: nonStrings

JV: used to be notifyLines... but that method

 setList: aCollection expandTabs: expandTabs redraw: doRedraw

JV: used to be notifyLines... but that method

 lineSpacing

(comment from inherited method)
get the lineSpacing - that's an additional number of pixels,
by which lines are vertically separated.

 beUnmodified

 isModified

 isReallyModified

 copyFrom: aDrawable x: srcX y: srcY toX: dstX y: dstY width: w height: h async: async

If doing a vertical scroll, optimized Gutter redraw by

 reallyModifiedChannel

return the valueHolder holding true if text was really modified.
This is different from #modified, as the inherited modified flag is cleared
to trigger another change notification with every keystroke (for the syntaxHighighter).
This may be (now) considered a very bad hack

 reallyModifiedChannel: aValueModel

set the reallyModifiedChannel - a valueHolder holding true,
if the text was really modified; that is: it was edited by the user
and the new text is different from the original (which is usually either
a file's contents, a method source or similar.
With this mechanism, we can hide the accept-cancel bar, if the user changes the
text back to the original (not all applications do this correctly).

 isQuickMenuModifierPressed

is the modifier-key for quick codeview actions pressed?
either CTRL or META

 isQuickMenuModifierReleased

 backgroundForVisibleLine: visLineNr default: bg

 drawFromVisibleLine: startVisLineNr to: endVisLineNr with: fg and: bg

draw a visible line range in fg/bg

 drawLine: line fromX: x inVisible: visLineNr with: fg and: bg

(comment from inherited method)
draw a given string at visible lines position with
given x position in fg/bg. Clears partial line before drawing the string.
Low level entry; not meant for public use.

 drawLine: lineStringArg inVisible: visLineNr col: col with: fg and: bg

(comment from inherited method)
draw single character at col index of visible line in fg/bg

 drawLine: lineStringArg inVisible: visLineNr from: startCol to: endColOrNil with: fg and: bg

(comment from inherited method)
draw part of a visible line in fg/bg

 drawLine: lineString inVisible: visLineNr from: startCol with: fg and: bg

(comment from inherited method)
draw right part of a visible line from startCol to end of line in fg/bg

 drawVisibleLine: visLineNr with: fg and: bg

(comment from inherited method)
draw a visible line in fg/bg

 redrawLines

redraw diff lines

 deleteCharBeforeCursor

delete single character to the left of cursor and move cursor to left

 getNewOriginText

 basicDeleteCharsAtLine: lineNr fromCol: startCol toCol: endCol

delete characters from startCol to endCol in line lineNr

 basicDeleteFromLine: startLineNr toLine: endLineNr

(comment from inherited method)
delete some lines.
Does not tell dependents

 basicDeleteLineWithoutRedraw: lineNr

(comment from inherited method)
delete line - no redraw;
Does not tell dependents
return true, if something was really deleted

 basicInsert: aCharacter atLine: lineNr col: colNr

insert a single character at lineNr/colNr;
set emphasis to character at current position

 basicMergeLine: lineNr removeBlanks: removeBlanks

merge line lineNr with line lineNr+1

 basicSplitLine: lineNr before: colNr

(comment from inherited method)
split the line linNr before colNr; the right part (from colNr)
is cut off and inserted after lineNr; the view is redrawn.
Does not tell dependents

 basicWithoutRedrawInsertLines: lines from: start to: end before: lineNr

(comment from inherited method)
insert a bunch of lines before line lineNr; the view is not redrawn.
Tabs are expanded here with a tab=8 setting (independent of any editor-setting,
because the text might have been pasted from an alien view.
Does not tell dependents

 basicWithoutRedrawInsertStringWithoutCRs: aString atLine: lineNr col: colNr

no - there was no cr inserted

 insertLines: someText from: start to: end before: lineNr
