Google Summer of Code Intern has Text Layout Problem
 
|
I don't understand too well how Squeak's styled text works. However,
my Google Summer of Code intern has some questions about it that I'm hoping someone more knowledgeable can answer. This is some <b>bold</b> text. I'm sure you get that. CSS uses a box model. Useful diagram here: http://www.w3.org/TR/REC-CSS2/box.html He's trying to figure out what to do if the user creates a style that says the b style has 20 pixel margins with a line border. How does he get the text to layout right and get the size/shape of the enclosure to draw the borders? Extra tricky if the bold section wraps for some fraction of lines. Is there an easy api he can use to embed wrappers around styles such that he can fiddle the margins/ borders? Thanks, -Todd |

Hmm, judging from the hoops we to jump through in Sophie he will do a line based layout/composition, as the the 20 pixel margin would require to also increase the line spacing around that line? The then needs to implement rendering runs to display the decoration for the length of the affected text.

Probably best to put the text morph inside another morph that handles the
border... I still have some problems with this, but maybe down to using different font technologies (TTCFont; FreeTypeFont etc.). I do find that the margins on TextMotph work, though need a bit of cajojing to actually update the layout! -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Michael Rueger Sent: 16 July 2007 5:50 pm To: The general-purpose Squeak developers list Subject: Re: Google Summer of Code Intern has Text Layout Problem Todd Blanchard wrote: > I don't understand too well how Squeak's styled text works.

You can put TextMorph inside a TransformMorph , to make layout management simple

Thanks, we will explore these approaches. As to the best way to embed the morph - is the
anchorMorph: aMorph at: aPoint type: anchorType the key method I want? Also, is TextMorph best? I notice there are a lot of variants. -Todd On Jul 16, 2007, at 7:00 PM, sig wrote:
