Oh this is cool. Nice work Nubeat.
I tried changing window sizes and it didn't go very well though (using version 3.0.4). Also it would be nice if the scrollbar mouse interaction could be based on exact mouse position so it doesn't scroll slower or faster than the cursor.

what do you mean with that?
just unlock the parent window and set the size you need for text window and sliders..

you can change the sensitivity in the properties panel... 5 is the value you would need for that

if you dont want to change this by hand all the time you can also include the sliders into the scroll area like i did here in the older scroll and zoom version - if you click and drag in the lower right corner you can scroll x&y at the same time with this

perfect nubeat!

btw: any chance to check in ruby that a Bitmap is done loading?
I tried this with a bitmap array but got to much (wrong) triggers...

U know: Give somebody an inch, and he will take a mile.

Ah I see now. Yeah it might be nice if the bars just scaled with the view size (complicated as that may be) but this works just fine! Maybe you could add an option to remove the X slider in the properties, since you'd probably rather set the text area to width and use word-wrap. Although I did notice that the word wrap didn't work quite right in some cases and would cut off some letters.

I also made a simple one. It's just like the "green" version.

[Nubeat7]

thanks Om, thats nice, whats that methode for ? setTextRenderingHint "clearTypeGridFit" and where did you know about it?

[TheOm]

I read about it in the User Guide. I think it sets what method is used for Text smoothing and hinting.
I played around with it and found that at least on my PC the modes "off" and "clearTypeGridFit" look much clearer and less blurry than the antiAlias modes, which are the default.

I know this is a really old post but I came across this phenomenon in one of my current projects.

From Nubeat7's original reply:

you can use the measureString methode for this, you can get the bounds of the area which the text would need with this (user guide page 164 for more detailed info)

while it looks like that it doesnt measure the width 100% right!?
you can see this if you change the fontsize from 2 to 2.2 it gets the right width with 2.2 but it cuts a little bit from the last t with a fontsize of 2.0

Page 165 of the user manual solves this:

Flag = 2048
Specifies that the space at the end of each line is included in a string measurement. By default, the
boundary rectangle returned by the Graphics::MeasureString method excludes the space at the end of
each line. Set this flag to include that space in the measurement.

Thought I'd mention this as it may help someone else
