RE: Set font dynamically to fit text
This is how I fit text into fields and buttons. This the first LC code I wrote back in LC 4.6. I did not follow best practices back then. After looking at it again I see that I optimized it so you don't have to set the textsize to some huge number. https://tinyurl.com/y2jtt877 Ralph DiMola IT Director Evergreen Information Services rdim...@evergreeninfo.net -Original Message- From: use-livecode [mailto:use-livecode-boun...@lists.runrev.com] On Behalf Of Sannyasin Brahmanathaswami via use-livecode Sent: Monday, October 14, 2019 3:21 PM To: How to use LiveCode Cc: Sannyasin Brahmanathaswami Subject: Re: Set font dynamically to fit text Dan: Thanks for the handler!

Font scaling itself is nonlinear enough, but the way margins scale with font size is downright psychotic (enough so, that I’d advocate for redoing it with a useOldMarginBehavior property that can be set.). Changing margin size can change what size font fits in the wrong direction, or by more points than the change, or . . . But the approach of an initial mathematical computation , followed by the iterations—which must happen in both directions unless a hit is made. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Re: Set font dynamically to fit text
Sannyasin, I've been doing this for years. Works well... on doShrinkToFit lFldID,startingSize,minSize set the textSize of lFldID to startingSize repeat until the formattedHeight of lFldID <= the height of lFldID set the textSize of lFldID to (the textSize of lFldID - 1) if the textSize of lFldID < minSize then exit repeat end if end repeat end doShrinkToFit Of course, the moment you start with this type of work, you'll immediately wish LiveCode would support fractional font sizes! Hope that helps... -Dan On 10/12/19, 5:21 PM, "use-livecode on behalf of Sannyasin Brahmanathaswami via use-livecode" wrote: Assuming one is not putting whole pages into small fields, does any one have an efficient run time LC algorithm that will set the font size so that the formatted text will all appear in the field without needing to scroll?

Re: Set font dynamically to fit text
In the repeat loop set the attributes of the empty field and use measureText (or measureUnicodeText) to compute the textSize. As a last step fill the field. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Re: Set font dynamically to fit text
But "line breaks" is another known factor, based on X… which still leaves us on variable to find.
