format text in TreeWidget.

[-- Attachment #1: Type: text/plain, Size: 1395 bytes --]

I did write the following code.

As the :tag text is  very long on some lines, and pass over the end the
line,  it is displayed on myltiple lines, and the tree looks spoiled. I wish
to make the tree widget show the text formatted correctly, and on maximum N
columns.




(widget-create (quote tree-widget) :node (quote (push-button :tag
"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" :format "%[%t%]
"))
 (quote (tree-widget :tag
"...............................................................................................................................................................................................)
"))
 (quote (tree-widget :tag
"#################################################################################################################################################################################################################################"))
 (quote (tree-widget :tag
"$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
$$$"))) <http://mail.gnu.org/mailman/listinfo/help-gnu-emacs>


How can I do this ?


Thanks for any help.

Hm, this somehow works, but is not perfect:

--8<---------------cut here---------------start------------->8---
(widget-create 'tree-widget
	       :node '(push-button :tag "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" :format "%[%t%]\n")
	       `(tree-widget
		 :tag ,(with-temp-buffer
			 (set-fill-column 50)
			 (insert "bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla")
			 (fill-paragraph)
			 (buffer-string)))
	       `(tree-widget
		 :tag ,(with-temp-buffer
			 (set-fill-column 60)
			 (insert "foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo")
			 (fill-paragraph)
			 (buffer-string)))
	       `(tree-widget
		 :tag ,(with-temp-buffer
			 (set-fill-column 70)
			 (insert "baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz")
			 (fill-paragraph)
			 (buffer-string))))
--8<---------------cut here---------------end--------------->8---

The problem is that only the first line has correct tree lines...

But maybe that's still a pointer into the right direction.

No.

Thanks for your answer.

No, your answer is wrong.

You did not understand what I meant.

I answer you so:

I do not like to create a tree like this :


|- aaaaaaaaaaaaa
aaaaaaaaaaaaaaa
|- bbbbbbbbbbbbb
bbbbbbbbbbbbbbb
`cccccccccccccccc
ccccccccccccccccc

but like this:


|- aaaaaaaaaaaaaaaaaaa
|  aaaaaaaaaaaaaaaaaaa
|- bbbbbbbbbbbbbbbbbbb
| bbbbbbbbbbbbbbbbbbbb
|-ccccccccccccccccccccccc
`ccccccccccccccccccccccc


In other words:

Is there a function fill-paragraph for tree-mode ?


Thanks.

Alin

I generate the tree in the following order:

XML - (xml-parse-tag) -> LISP - (defining xml-tags as lisp functions) ->
tree-widget format.

I can insert to te level "xml-tags as lisp functions" an accumulator to help
me know the

:level N

of every tree-widget element. N can represens the number of columns at the
beginning of a line used by "group"

||||||||| [N times]

Supposing you have a (:level N) element for every element of tree-widget,
how do you define a fill-paragraph function in tree-widget mode ?

Please help from the author of tree-widget and everybody else who knows it .


Alin.

You could look at the value of (widget-get widget :indent) and emit a
string that is filled accordingly.
