Trying to make a class that extends ParagraphView work in WrappedPlainView

Do you want to scroll to the right at all? If not you could just set the property of the scroll bar to never show up:

scroll.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);

I see this:
with extends ParagraphView:
1 sdasds
2 ewoifnwoin4r2fine
3 asdfeiwncwe...
4
...
and a scrollbar appear to the right only when the number of row are bigger than the window size (25).
continuing typing on the same line, when the right margin is reached, a new line is created (and numerated)

with extends WrappedPlainView:
1 fasdfòsdafsdjfajsdòlfkjsdkf
2 asdfjkadjfòjj
3
...
and a scrollbar appear to the right only when the number of row are bigger than the window size (25).
on the bottom appear a scollbar ever (even if the row typed are less than the windows size).
continuing typing on the same line, when the right margin is reached, the typing continue on the same line (not into a new line)

What you want to change?

I am sorry...try this code instead...the problem only happens when you open a file with it

It keeps scrolling to the right non stop...

I see a resizing in the code.
Now investigating about it.

ok..thanks dude

still no idea?

So you just add that method and it worked?

Where does this method gets called?

>So you just add that method and it worked?
yes, the second version.

>Where does this method gets called?
I think this method is called when a component is added. So when something is read a setSize is called (for each char of line).

Hope this help you.
Bye, Giant.

I just started learning Swing a couple of weeks ago and so I kinda suck at it =(

Do you have any recommendations which site is good for learning Swing?

I am learning Swing from Sun's Swing tutorials but I think their tutorials are very basic.

Yup...thanks a lot for your help again =)

Ur good!

The Sun Tutorial for Swing is a good basic tutorial.
I suggest you to learn at a realy good level this tutorial.
Another at basic level is here:
http://www.apl.jhu.edu/~hall/java/Swing-Tutorial/

For particular things about Swing I personally like to search over the net because in this manner I see all the approaches available.

Thanks. Hapy to help you.
:)

Bye, Giant.
