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>
