[flexcomponents] Re: WYSIWYG Rich Text Editor for Flex 2

[Bjorn Schultheiss]

I dont think it would be that difficult to build. Just a really smart idea.   I must say this is why i love flash/flex dev. 1 problem, Many solutions. It's where programming and art come together.   Regards,   Bjorn Schultheiss From: flexcomponents@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Ted Patrick Sent: Wednesday, 27 September 2006 9:56 AM To: flexcomponents@yahoogroups.com Subject: RE: [flexcomponents] Re: WYSIWYG Rich Text Editor for Flex 2 Bjorn, You are reading me loud and clear! Trying to extract a small AS3 sample from Beau as a simple case/howto.

From what i get, you can create a box based off TextLineMetrics and apply a filter or blend mode to the box.. Thus creating your coloring effect without having to update any text. Now maybe thats not what teds point was but still interesting.

I google for Beau Amber, but didn´t found his highlighter. I didn´t understand how apply filters can be done to certain words. About my tests: I load some text in text property of textfield and discovery that the maximum usable is 50,000 chars. More than that, each time you press a key, a perceptible delay happens. A code file with fifty thousand chars has about one thousand and a half lines. On 9/26/06, Ted Patrick <[EMAIL PROTECTED]com> wrote: A great way to do this is via Filters. Beau Amber wrote a highlighter for AS3 using the Flex Components. Within a TextArea control, he used Regex to find matches and used filters to color highlight certain words. When the text was scrolled or changed, the filtering was removed for performance, then reapplied when the change stopped. As the highlighting only effects the viewable portion of the textArea, it was quite fast. It was rare to actually see it flicker at all. I would avoid the HTMLText route and use imaging to support your needs. I would not have recommended this initially but seeing it actually work changed my mind.

That means that on every stroke the player has to reparse the entire htmlText, recreate all the style runs, and redo all the line wrapping based on new measurement. No matter how fast the Player got, that design wouldn't scale to arbitrarily large documents. - Gordon From: flexcomponents@yahoogroups.com [mailto:flexcomponents@yahoogroups.com] On Behalf Of Flex Brasil Sent: Tuesday, September 26, 2006 12:44 PM To: flexcomponents@yahoogroups.com Subject: Re: [flexcomponents] Re: WYSIWYG Rich Text Editor for Flex 2 Yes, i´m trying to do a code editor. Since it´s just for learn purpose, 3000 chars is ok, but would be nice support normal file size. I didn´t try replace/setTextFormat. What I do is every stroke, parse the text property and generate an html wich I set to htmlText. I don´t know how to do a highligher that can work with fragments of text, what would be much faster. My highlighter is a mix of tokenizer and regular _expression_. I´m doing a benchmark class to analyze where are the bottle necks on my algorithm.

I´m doing a sintaxe highlighter but with a text bigger than 3000 chars, the input became slow in my machine that is an Athlon 64 3GHz with 1GB ram!!!

However, we know it is possible to make a very advanced text editor, rivalling desktop editors. Flash is ready, but it is just a hell of a lot of work.

All I am saying is be an engineer - inventor, don't limit yourself to what you think you can do, try to do what you can't do.
