App Designer Edit Field precision

19 views (last 30 days)
I have Outputs in App Designer as numeric edit fields (b0,b1,b2). These display calculated values and cause they are output values I don’t want them to be changed by the user. So I disabled the `editable` option, but that isn’t quite satisfactory, cause I like the behaviour of the editable option.
To be more precise, when you click on an editable field, you get a higher decimal precision. Like in the pictures, where I made b1 editable.
What I want to archive is an field, which shows me more decimal places, when I click it, but doesn’t accept any input.
Hopefully it’s understandable what I’m looking for and someone knows a way to do this.

Okay, found a solution which is good enough for my requirements.
I just saved the b Parameters as properties. Thenn I used a callback for each edit field which checks if the value has changed against these properties. Whenever it is changed, it will reset. With this I can leave the field editable, but it can't be changed from the user interface, only from the intern function.

When you select the field, you can edit the ValueDisplayFormat code. Now it is apparently in some kind of scientific notation mode. If you want to have it in a float notation, try e.g.
there, which means your numbers will show as a float with 0 digits before the dot and 10 digits behind the dot. You can customize this as you wish.

Then I don't know if Matlab supports such behavior.
