Automatic new line in text field

lbtony · Post by **lbtony** » Thu May 04, 2006 1:42 pm

I have a text field with multiple lines. I want the cursor to go to the beginning of the next line when it reaches the end of current line. How to do this? At the moment, when the cursor reaches the end of a line, it just keeps going beyond the bound, I and can't find something in the prop settings to solve this problem. Thank you....

set the 'dontWrap' of the field to true

Open the property inspector of your field and uncheck the Don't Wrap checkbox. You can also use this syntax:

set the dontWrap of fld "Your Field" to false

Best regards,

You can then select after line x of field y

and with the don'tWrap as false it will jump to the end of the line.

Unfortunately, unchecking the "don't wrap" field doesn't seem to work. it still keeps going to the right but doesn't start a new line.
P.S.
I used a Text Entry Field with multiple lines.
Do I also need some handlers to do this?

Hi,

it will only break the line if the contents of the line is not a single word. As soon as there is a space in it it will work, but I think that is not what you are after...

What you want might be possible to script though...

A quick start out of the top of my head:

In the fields script

Code: Select all

on keyDown theKey
  if the formattedWidth of me > the width of me then
    put cr before char -1 of line -1 of me
    put theKey after line -1 of me
    select after line -1 of me
  else
    pass keydown
  end if
end keyDown

Hope that helps,

Malte

Just checked and it works, given you type continiously and keep the text insertion point always at the end of the field. If you need a more sophisticated version, that takes care of changing the insertion point please let me know.

All the best,

Malte

Now, fogive me being curiouse please, Tony, but what do you need it for?

Thanks Malte, thats really helpful....
The reason I need it is because I have a quite narrow text field on a quite narrow stack

so on some lines it goes out of bound, but I want all the text to be displayed

to be honest, I'm a bit new to runrev, so I'm sorry if my questions sound naive

Hi Tony,

It is not naive at all, in fact your idea is very good and it is very understandable that you don't immediately think of the formattedwidth when you're new to Rev.

Enjoy the Revolution.
