splitting a long string into multiple strings

[reven]

not a fan of using percentage, rather define a fixed number of pixels. so doesnt matter how big or small the textbox is defined (since its fully skinnable) it will always move up and down the same amount.

is there anyway to calculate how many pages there are? well say how many times the text fills the textbox, would be nice to show
1/3 [pgup][pgdwn]
like i do for the rest. also the percent would come in handy there, just set percent to 100% to jump to next page (which was how i wanted it orginally, but i like the scroll). if couse if there are 2.0000001 pages, it should be rounded up to 3 pages etc.

You'd have to add this functionality.  

The data is readily available, just not publically exposed.  If you look at the code, the following gets set during render():

vscrollbar.ItemCount = bm.Height;
vscrollbar.ItemsDisplayed = (int)renderArea.Height;
vscrollbar.ScrollIndex = currentScrollY;

So all you need to do is look the these properties of the scrollbar for the current scrolldirection (either the VScrollBar or the HScrollBar).

# of pages: 1 + (int) (itemcount / itemsdisplayed)
current page: 1 + (int) (scrollindex / itemsdisplayed)

ok ill add them, and then post the methods i use, so you can update the original source. also ill look into doing a horizontal scrolling textbox, for news tickers or for things that dont completely fit on one line.

theory goes.
create image of text
if width <= maxwidth
>then ok
elseif width>maxwidth
>create two images, one with text another with text with a starting and ending " | ", then just move the position imgA at x=0, imgB at imgA.x+imgA.Width, if imgA.x+imgA.Width <0 imgA.x= imgB.x+imgB.Width, and then repeat for imgB.

should be simple enough, given the source code for the scrollingtextbox.

[jasonf]

Uh, you lost me.

Maybe you didn't realize that this is already a horizontal scrolling textbox too? That's what the ScrollDirection property does (either Horizontal or Vertical).

[reven]

yeah i was thinking something a little lighter, just a one line display that if is longer than the bounds, will just scroll left, and loop with a "|" at the end of the string.
[gbpvr is coo]  (so 4chars max) 1st time
[bpvr is cool] 2nd
[pvr is cool ] 3rd
[vr is cool |] 4th
[r is cool | g] etc. (not defined by char length, but image width, hard to explain).

good for a news ticker on the main menu, or to display filenames, no need for for scroll bars, just repainted every second (or well as often as possible) constantly ticking away.  

only things that need to be defined are
text.Text
text.Font
text.FontColor
text.Shadow = false
text.Scroll = true (
text.ScrollSize (how many pixels it should move)
text.ScrollDirection (left/right).
text.Render(g).
text.Size/Bound/Err whatever you called it before.

now is it more clear? if you want to have a stab at it, let me know, you'd do a much better job at it than me (never actually made a control before).

Just like a single line text box

[jasonf]

Got it. I'll think about that for a bit--seems like a minor modification to the existing control.

might want to rename textbox to textarea and use textbox as the single line one, java does this, i have no idea why c# never did, one thing i prefer in java.

yes java does have a few good things, but in general c# is better.

i prefer the java way of doing implements and extends aswell.
