RE: Vertically aligning text in a field
Hi Jaque, I needed to know where the hGrid line of line 1 shows. I did not get there by adding: top of field, topMargin, borderSize and effective textHeight. So I don't know what I missed but that calculation gives me a 7 pixel offset i.e. the position is 7 pixel below the hGrid of line 1. I don't know what these 7 pixel are. Then I went into experimentation mode and found that empiric formula. Maybe someone has an idea how to calculate the hGrid position of line 1 of an EMPTY field in a straight forward way.

Re: Vertically aligning text in a field
Not sure what's up with the offset that seems constant and inherent, but this corrects for it. It does nothing about the apparent offset caused by the difference between the textheight and and textsize of the first line, because if the size varies, the textsize returns mixed. In any case, this works for me to a reasonable degree of accuracy: set the topmargin of fld 1 to (8 + the height of fld 1 - the formattedheight of line 1 to -1 of fld 1) div 2 Here's a demo stack that shows what this does. Each time you click the Test button the text changes, then vertically aligns, then puts in two equal-height boxes above and below to show the results. https://dl.dropboxusercontent.com/u/41182876/vertical%20text%20demo.livecode On Sat, Dec 20, 2014 at 11:24 AM, J.

Thank you very much for this code. I was surprised that LC did not have an option for vertically aligned text in a field and on searching the forum found your method. However, on my iMac the offset calculation did not seem to work precisely and I had to adjust it slightly. As I am creating a report stack for printing tables that may have different fonts and font sizes with different row(field) heights provided as parameters I was looking for a reliable way to centre text vertically with the possibility of many options.

Re: Vertically aligning text in a field
Hi Terry: FWIW, I¹ve never been able to get the field adjustment code working for anything but default text. I¹ve pretty much given up on using fields for vertically centered text and use buttons where possible. Once you establish a topMargin offset to center the text (you can use a negative margin value via script even though the Inspector doesn¹t accept negative numbers), the text will automatically stay vertically centered, regardless of how the button is scaled.

Hi Geoff, both code versions were intended for fixedLineHeight text. But now you mention it I will try to adjust the code for variable lineHeight and varying fonts. Since am currently doing cantuccini (sort of italian cookies) I will try it a little later. I think the solution is not to rely on the textHeight but to calculate from the formattedHeight / 2 in code version 2. Put that into the offset. I have not tried it though yet.

Re: Vertically aligning text in a field
Hi Geoff, I think I found a solution for variable textHeight and different fonts in a field. Try this. It is now independent from the textHeight and just uses the formattedHeight. And no need to watch out for wrapped text. Should work with any text whose formattedRect and is reported correctly, which apparently according to Ralph is not always the case on mobile devices. This is again for scrollbar for a field you configure to your liking. You can optionally have visual feedback when you make 3 horizontal line graphics and name them as stated in the script. The textSize is only changed for the lines that don't have their textSize set explicitly. Uncheck fixed textHeight in the properties inspector.

RE: Vertically aligning text in a field
Hi Ralph, I have not tried this all on mobile devices. But on desktops the baseline of the first line is consistently found with this piece of code. I had the need for a starting point for a gradient behind the text and had difficulties finding a consitent reference point. I found the base line of line 1 and from then on the textHeight is ok. There is something in the first line that is not exactly the textHeight. Or I haven't found it. Anyways here is the code for a field with fixedTextHeight. TextHeight can be manually/by script set to be different from the automatic textHeight when choosing a textSize. Margins border are taken into account. This piece of code is surpisingly robust... this is on mouseEnter for a a field, make a horizontal line graphic gBaseLine to see where it is and turn in the Properties Inspector - Table - hGrid on to see the base lines as always watch out for line breaks - on mouseEnter -- now calculate the position of the first base line of the first line of the field. -- = first horizontal divider from top -- the gradient should go there -- find out difference between automatic textheight and manually set textHeight -- formula according to documentation put the effective textSize of me into tTextSize put trunc(4/3*tTextSize) into tRegularTextHeight put the effective textHeight of me - tRegularTextHeight into tDiff -- the first line is not the formattedHeight but changes according to the font size -- formula found by experimentation put round (((tTextSize - 22) * 1/3)) into tKorr -- NOTE added 1 to the calculated From -- the vertical coordinate of the gradient from put the top of me + the effective textSize of me + the borderWidth of me \ + the topMargin of me + tKorr + tDiff into tFirstBaseLineY put the vScroll of me into tVScroll subtract tVScroll from tYofFirstBaseLine if there is a graphic gBaseLine then set the top of grc gBaseLine to tFirstBaseLineY end if end mouseEnter - Ralph DiMola wrote I have been working on this for a while. I found out that the base line is different on various platforms. This makes the calculation change on various platforms.

Re: Vertically aligning text in a field
Hi Terry, Look at my reply to Geoff. I think this is more the solution you need because that code makes no assumptions about fixed textHeight, line wrapping and so on. It should work for any type of field and center what is visible vertically. Kind regards Bernd Terence Heaford wrote Thank you very much for this code. I was surprised that LC did not have an option for vertically aligned text in a field and on searching the forum found your method. However, on my iMac the offset calculation did not seem to work precisely and I had to adjust it slightly. As I am creating a report stack for printing tables that may have different fonts and font sizes with different row(field) heights provided as parameters I was looking for a reliable way to centre text vertically with the possibility of many options. Thanks again, this really looks like the answer. I will report back if anything looks odd in testing.

Hi Bernd, Thanks very much for all your efforts, on first use there does not appear to be any issues.

Vertically aligning text in a field
Is there a definitive calculation that correctly sets the position of text vertically in a field? I am using LC 6.7. I have come across a few ideas like the one below that all appear to use an arbitrary offset to the margins, is there a method to calculate this accurately? put the effective textSize of fld id tID into tTextSize -- put round (((tTextSize - 22) * 1/3)) into tOffset put round (((tTextSize - 24) * 1/3)) into tOffset put the formattedheight of char 1 to - 1 of fld id tID into tFormattedHeight put round((the height of fld id tID - tFormattedHeight) / 2) into tVerticalMargins put tVerticalMargins - tOffset into tTopMargin put tVerticalMargins + tOffset into tBottomMargin set the margins of fld id tID to 8,tTopMargin,8,tBottomMargin All the best Terry ___ 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: Vertically aligning text in a field
Hi Terry, There's a long discussion about this on the forum. I believe I did a good attempt, but Bernd's solution was probably the most reliable. -- Best regards, Mark Schonewille Economy-x-Talk Consulting and Software Engineering Homepage: http://economy-x-talk.com Twitter: http://twitter.com/xtalkprogrammer KvK: 50277553 Installer Maker for LiveCode: http://qery.us/468 Buy my new book Programming LiveCode for the Real Beginner http://qery.us/3fi LiveCode on Facebook: https://www.facebook.com/groups/runrev/ On 12/16/2014 11:54, Terence Heaford wrote: Is there a definitive calculation that correctly sets the position of text vertically in a field?
