How to scroll text?

[broconne]

If you have a text panel and the text is too big for that text panel - what are the steps required to make the text scroll when that component is focused?

I was looking for a "scroll text" checkmark in the text properties - but didn't see it :-)

I just had this same issue. The solution was to write a completely new text entry dialog from scratch (with help from jaminben) which handles every keystroke and takes the necessary actions. It was a PITA.

PM me your email address and I'll send you the code I developed. I don't recommend starting from scratch.

Or you could just copy smm method which is much easier

And where would somebody interested in plagiarizing your work look to find that?

If you're talking about text display (not text input), then you need to set the panel's Scrolling property to Vertical and provide a set of scrollbar controls that fire the Page Up and Page Down events when clicked. There are plenty of examples of this in the stock STV (e.g. the Airing Details or System Information screens).

Smm list view I found a better way of doing it but haven't updated fully the only difference is I clip it now to stay in the box.

Does it also handle editing the text using arrows, Insert, Delete, Backspace, Home and End keys? That was important functionality and I didn't find any existing STV code that did that. I *think* SageMC had that capability but it was implemented in java and would require a dependency on one of the SageMC JAR files.

Confused why would you want to edit scrolling text?

Cool - I am only looking to display - not for editing.. So I am not sure that code share will help me..

However, I certainly don't want to start from scratch.

Vertical?? That seems really counter intuitive to me..

I didn't remember anything auto-scrolling in the stock STV.. I will go take a look.

In the stock STV, and anywhere else I looked, if you are using text input and the length of the text exceeds the size of the text input area the text gets "cut off" on the right side and it just displays as "...".

Sorry, I assumed you were trying to make a vertically-scrollable panel of wrapped text (like the examples I cited).

But if your goal is a single line of horizontally-scrollable text, the same considerations should apply. Just choose Horizontal instead of Vertical scrolling on the panel, and disable word-wrapping on the Text widget.

Or are you talking about a ticker-style text display that scrolls continuously without user intervention? That would be a different kettle of fish.

So maybe you could clarify exactly what you're trying to do so we can target our advice appropriately.

Nope - sorry it wasn't clear.


I am trying to do exactly what plucky does in SMM list view. I have text that is too big to fit into a single text area. I don't like how it looks when the text is "shrunk" to fit. When the user move the focus to the text, I want the text to automatically scroll so the user can see the full title text.

You mean something like what was discussed in this thread? Not the text entry bit but the other normal scrolling text further down in the thread. If so I think your probably better off getting Pluckys version to work as the table method isn't all that friendly with text spacings.

Yeah - pretty much exactly as you had it working in Ortus in that video..

sigh - that thing looked pretty :-)
