Req: Text Viewer in ruby with scroller

Postby Walter Sommerfeld » Sun Aug 31, 2014 7:37 pm

I'm a little lost in the text scroller thingy

I have some knowledge of String (array), file & bitmap handling in ruby...

but this scroller isn't easy for me...
especially maybe with a redraw limiter inside?!

Any help is greatly appreciated.

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

you are welcome Walter, i wouldn't have looked for it without your question, luckely there is this new setViewSize methode in 3.05 what i wanted to try but couldn't find some useful stuff for it, till now! :)

i reuploaded the schematic with variable slider size, so that the slider size is in relation to the shown window and the content size window, so the slider size gets smaller the more way to scroll..

Even more awesome :)

setViewSize is really a tricky thing - i like it very much - good work!

Keep on doing!

it looks like the toolbox doesn't like it when view is maximized, so just minimize theview on the top level and it should work..

its the setViewSize methode, i think its because the dynamic resizing of the view, but you can get rid of it too, then you just need to take care that the containing window is greater or equal to the max text area (which is defined in the measureString methode)

here is an updated version, which doesn't use the setViewSize methode (so it should work with fs 3.04 too), the maximum text area is the size of the text window, i think this is a better solution for it anyway because like this you don't need to change the max text area at the stringMeasure methode,

i also integrated a properties panel where you can set textsize, font, margins and colors...
