Text vertical alignment

[bn]

Hi Marek,

I was only joking when I said: "glad you asked". Although I did not want to let the formula unexplained and it is always a good idea to understand what is going on.

Regarding the datagrid: I only have used it once or twice to test it and I had no real need for it. So I am not in a position to give you advice on that.

It may be a good idea to open a new thread with your datagrid question.

Kind regards
Bernd

Thanks Mark,

although a little off the track it can be handy in rare circumstances. Like when you want to position a graphic with a gradient as an alternating line background for a list field or table field... But that gets really weird by then.

Thanks Berndt for sample stack.

Hey Bernd why does

Code: Select all

put the formattedHeight of char 1 to -1 of field 1 into tVariable

give a different result than

Code: Select all

put the formattedHeight of field 1 into tVariable

On a related note, in my own investigations I have found that 6 + 2/3 (6.6666666666666666666) is the magic number.
Subtracting it from a multiple of the text size yields reliable vertical positioning results. I painstakingly measured the pixels and drew graphs to discover this.

Hi nlexa,

put the formattedHeight of field 1 into tVariable

the formattedHeight of char 1 to - 1 of field 1 means just the text whereas
the formattedHeight of field 1 also includes (besides the text) margins, borderwidth and scrollbars.

could you post a sample script or better a sample stack?

as for the formattedHeight of a field I attach a little stack, attention it could make you dizzy, use at your own risk...

Nice stack Bernd

Here is an example stack for you.

You will notice when you turn off the correction and make the margins 0 that as you decrease the text size it starts disappearing into the top of the field as per normal.

If you use the right ratio (multiplier) applied to the text size and subtract 20/3 (the magic number) and subtract all of this from your margins (which at smaller sizes is addition, minus a minus) you get the text to stay the same distance from the top as it does from the left as dictated by the margin value.

I'm sure the stack and the code will better explain what I'm getting at.

Kind regards

Here is an update. Now you can adjust the text height also.
I'm not much of a programmer and more of a graphic designer so trying to get the text to line up correctly was really starting to wind me up . I'm sure there are others out there who are as visually pedantic as me so I'm sharing this .

Hi nlexa,

thanks for the two stacks, very nifty, now with the seocnd stack I understand better what you are after.

Kind regards

Ender...

nice solution !

Thanks Dixie.

It wasn't perfect as many pointed it out.
This kinda things can hardly be handled with a single line of code.
Besides, I was a total novice back then; posting a solution was a bold move


Best,

Thanks Bernd

That slight amount 'off' I was getting was driving me potty (and it would drive my client - who is VERY interested in details - bananas)

Nice work

Dave,

thank you. I am glad it helped.

you said:

reminds me of a hilarious (IMHO) reader comment on "The Register" to this article
http://www.theregister.co.uk/2007/08/31 ... a_ripener/

where a company was looking for an

Trainee Assistant Banana Ripener

The reader comment:

Poor industrial relations
I used to have this job! Terrible workplace culture, the forklift operators drove me bananas...

Well I got carried away a bit, I am afraid.

Kind regards

Um thanks for the story Bernd - I've thought more about bananas in the last five minutes than I ever have before...
