Example of a scrolling list field text centered vertically

[bn]

Hi all,

I post a stack that shows a scrolling list field for iOS that centers the text vertically.

I set the HTMLtext of the field with superscript of the text. Then I apply a textShift to adjust the amount of pixels for superscript to center the text vertically.

The logic is in the "fill field" button.

Kind regards

Hi Bernd:

The dev team is implementing so many new features and at such a fast pace that they don't have the time to provide sample code for every new addition they incorporate into the language. Code samples like the one you have provided saves the developer community a ton of time spent in trial and error trying to figure out what works and what doesn't.

Thank you so much for posting this sample stack and for actively helping out in this forum!

Cheers

Hi,

Thanks for this example work really fast and smoothy.

I thinking about how to show two lines into each row, maybe with HTML format and setting a <BR> and other text size for the second row?

Hi Josep:

Your idea might work but a separate solution would be to go with a datagrid. You have full control on what you want to display in a datagrid.

Yes, but the scroller movement are very buggy and the performance is low.

Thougths?

Hello Bernd: Thanks for posting this. However, I was looking for a solution that performs like a standard iOS scrolling field (smooth scroll with fast refresh). Your code works, but the scroll is not smooth and seems intermittent. There is another solution that I found in the forum called "My Scroller", and it seems slightly smoother, but still not the same as a standard scrolling field. (I am running on an iPhone 4).

Hi Bernd,

Is it possible to turn off the on mouseUp bg hilite on certain lines of list.

Thanks,

Hi DebDoot,

Is it possible to turn off the on mouseUp bg hilite on certain lines of list.

could you please explain what the conditions to turn hilite of lines on and off?. It is actually a list field and if you can specify a little I see if I can do something.

Kind regards

Hi Bernd,

could you please explain what the conditions to turn hilite of lines on and off?. It is actually a list field and if you can specify a little I see if I can do something.

What I was trying to do is something like the following:

line varClickLine of fld "fldRolf" = 1 then
disable line 1 of fld "fldRolf"
exit mouseup

I did not want the hilite to work in certain lines of the list if you clicked on them.

Hi debdoot,

in the script of the field "fldRolf" there is a part of the code that decides whether it is a click or not. Then it sets the hilite of that line:

Code: Select all

 if (abs(the mouseV - sY) < 10) and (abs(the mouseH - sX) < 10) and (tTestForEmpty <> "") then 
      put true into tIsAClick
      put word 2 of the mouseLine into tClick
      set the hilitedLine of me to tClick
   end if

If you put your conditional around "set the hilitedLine of me to tClick" you can suppress the hiliting of the line. If you also don't want an action like going to the next card you could include the "put true into tIsAClick" into your conditional.

Kind regards

Bernd
