Has text selection changed?

That is spot on... I have implemented Squiggly for my "pure TLF" text inputs, calling clear before I run through and underline the misspelled words.

Just in case anyone finds this thread when searching for Squiggly, the way I did it was:

• Find TextRanges for misspelled words:
  • Get the first Paragraph using textFlow.getFirstLeaf().getParagraph()
  • Loop through all Paragraphs using para.getNextParagraph()
  • For each, run a Regex match (/\b\w+\b/) on para.getText()
  • Spellcheck each result using Squiggly, and for bad words store a TextRange: TextRange(textFlow, para.getAbsoluteStart()+index, para.getAbsoluteStart()+index+word.length-1); where index is incremented to the position proceeding the end of each word (match or no match).

• Spellcheck class:
  • Created a static SpellCheck class which loads language dictionary (downloaded from OpenOffice website) and a UserDictionary (stored as a simple text file)
  • Added methods for checkTextFlow(textFlow:TextFlow):Array which returns an array of "bad" TextRanges, a method for getSuggestions(word:String):Array and methods for checkWord() and addUserWord().

• Context menu:
  • Extend ContainerController and override menuSelectHandler()... use an instance of my CustomContainerController when creating the TextFlow:
  •   textFlow.flowComposer.addController( new CustomContainerController() );  
  • Loop through flowComposer.numLines, obtain each TextFlowLine from flowComposer and therefore each TextLine.
  • Determine if textLine.getBounds(container).container(container.mouseX, container.mouseY) to find the line they right-clicked.
  • Get the "raw text" for the line: textLine.textBlock.content.rawText.substr(textLine.textBlockBeginIndex);
  • Find the atom clicked: textLine.getAtomIndexAtPoint(container.stage.mouseX, container.stage.mouseY).
  • Find the starting atom of the word (reverse lookup for word boundary i.e.. " " or first char in raw text).
  • Determine the word itself by using regex to find the first word from this starting point (/\b\w+\b/).
  • Add ContextMenuItems for "add to dictionary" and suggested words (for the latter also store start/end atoms in ContextMenuItem.data).
  • When user clicks a suggested word, use (interactionManager as EditManager).selectRange(data.start, data.end); (interactionManager as EditManager).insertText(data.word) where "data" is the data property of the clicked ContextMenuItem.

• In my "EditableTextField" class, I call my SpellCheck.checkTextFlow() to get the bad TextRanges and...
  •   Loop through the badRanges array.
  •   Loop from range.absoluteStart to range.absoluteEnd for each TextRange.
  •   Find TextFlowLine for "i" in this loop, and therefore the TextLine: containerController.flowComposer.findLineAtPosition(i); textFlowLine.getTextLine();
  •   Find atom bounds using textLine.getAtomBounds(charIndex); where charIndex is: i - textFlowLine.absoluteStart.
  •   Underline... drawRect( bounds.x + textLine.x, bounds.y + textLine.y + bounds.height - textLine.descent - 1, bounds.width, 3)

I'm sure there is a more elegant way, but this seems to work. I believe I read Adobe are working on Squiggly for pure TLF, if not, I hope this helps somebody get on the right track.

I'd paste the code but as this is for a client I can't paste the full contents of the class-files without permission or sufficient modification first.

Thanks again, Richard
