XControl - Unicode Ring Text: some questions...

[J-M]

It is my first "real" XControl and I have some questions.

Open "Main Test.vi" and run the VI.

 

Question 1: The value of my XControl is always 65535 (U16), and in this case it is supposed to be between 0 and 3 (four elements).  What I am doing wrong?

 

Question 2:  Why when I drop a new XControl on the front panel, the size is bigger than it should be?

Question 3:  Do you suggestions to improve this XControl?

[J-M]

Question 1: I am ashamed. It is a "less than zero" instead of "greater or equal" ...

Hey J-M,

For question 2: Are you using LabVIEW 2013 SP1 or just LabVIEW 2013? 

For question 3: You can check out this documentation on X controls:

Hi Griffindor,

Question 2: I am using LV2013 SP1 and I have the same behavior with LV2015.

I already read this tutorial.

Jean-Marc,

I updated your code and appears to fix the problems.  I did not try everything out, so do not know if my "fixes" broke something you already fixed.

Basically, I did the following:

1. Changed the string control to fit to pane
2. Instead of using Vi reference in your Display State change event, I used the control reference from the contatiner cluster.
3. Modified your Vi which resized everything to set the XControl container size to the string size.  This may need to be played with by a couple of pixels incase the borders cause some issues.  At first glance, it is OK.
