Scrollable container and wildcard values

HHarj.1 · ‎2020-02-19

Hello again,

I have a bunch of measurement results that I would like to display on the screen but space is getting too little. I looked at the scrollable container example, where the long text was put as a text resource (or whatever that is). However, my measurement results aren't, of course, static text so I would need to use wildcard text buffers. How could I implement this?

Hi,

What do you meant by "Space is getting too little"? Could you use multiple textArea widgets instead of one big one?

Could you add a screenshot of what your project looks like on Designer and possibly a bit more detail on what you wish to show? Some of the other examples might help you where they show a fixed text and changing values (for example the RadioButton example where Ressource is used but with non static text)

Hi,

here is an example. I am using multiple text area widgets. There is a static text area for each measurement result (V1, V2..etc) and then a wildcard buffer for each of them. There are more results I would like to display than I can get fit on the display. Therefore I thought a scrollable container would be good, but I don't know how to implement that with wildcard values. I know how to do that with static text or normally with wildcard values when everything fits on the screen. I can make the font size smaller, but you can only do that for a certain point and it's not a good solution.

Instead of a scrollable container use a scollWheel or scrollList. I believe this is exactly what you need for your situation since you can have as many elements as you like with the textArea widgets you need. You can have a look at Tutorial 4 and at some of the projects using those widgets (some examples configure the scrollWheel or list through code and not designer directly, like in Demo 3).

Yes, that's what I was looking for. Thank you.

I looked at the scrollWheel tutorial. I think I would rather need to use the scrollList widget. Could you give me a pointer or a few how should I do that? I have 3 series of measurement results that I want to display. I would like that the all those 1s would be running index numbers and results (those 0s on that picture) wildcard values. Now they are in 3 separate scrollLists, but it would be best if they were in one. Is that possible since the text area seems to have 2 wildcard values maximum? I can live without that if I can get this otherwise working. Thanks in advance!

Edit: Should think a bit before blurting all out. Figured out I can make a custom container with 3 text areas and each with 2 wildcard values...

I read the tutorial about the Scroll List widget and tried to implement that but have to admit again my lack of competence.

I tried to implement the setValue function but no success. I would need some help doing that since I'm getting errors.

Hi,

I'll try to give you a better example if I have time this weekend. This could be useful for other people struggling with List and Wheel implementation.

That would be much appreciated. I look forward to it.

Hey,

bumping this up while I am doing lists manually since I can't update those values...a tedious job I can tell! I'm sure an example of a scroll list widget would be useful to many.
