Scrolling Multi-line text indicator

[delbertson]

Hi there,

I was wondering if anyone had any hints to help me solve the following problem.

I'm wanting to create a Text Output window, that displays messages to the user.  As the text box fills I'd like it to scroll so that the latest message is displayed on the bottom line and the oldest message scolls of the top.  Sounds simple enough but just can't get it.

I've attached an example.

Thanks in Advance

Derek

Hi Derek,

there's a property node describing the scroll position of the string indicator. Everytime you add text to the string you should set this property to the end of text. I'm not sure if it wants to have "number of lines" or "number of chars" as I don't have LabView at hand...

Hello,

Gerdw it's correct. The property "scroll position" can do what you want. The help says "position of the scroll box in the scroll bar".

You can see in the attach pic where you can find it.

Thanks to both off you for replying.

Both answers get an excellent rating... but for some reason, I can't see the ratings bit... odd they were there last week

Hi,

Also when i use a scroll / log output window instead of reading how big it is then setting the scroll position to the end of the data, i just give the scroll property node the largest value it can recieve 2^32 if i remember.  That way it is always at the bottom and you dont have to read current values etc.

Hi Derek,

You have to be signed in to be able to see the rating. Have you done that?

PS: every time youpost a question, don't forget to say the labview version. By the point we can see if it's possible to send you an example.

Hi Derek,

the rating system changed a little bit in the last days. You have to have a minimum number of posts now

Yeah... I'm logged in my name appears top left... but no ratings bit.  Also I only have one reply button at the top of the thread, from memory there should be one next each post!

Thanks for the extra tip Craig, I was searching the Text for carriage returns... but that's much easier

Hi,

As an extra tip i usually add in an auto scroll boolean (I use the checkbox) for when you want to read back the text.  However im sure you would have thought ahead 😉
