Hi all,
I would like to create a Widget for PIER which will generate a HTML page
by using the tree structure of PIER with a visitor. Currently I have
created a test by creating a visitor who overloads PRViewRenderer (PIER
-SEASIDE). Unfortunately I encounter a problem of context when I launch
my app. Can you help me to understand how to create a temporary context?
Sample of my code:
kernel := PRKernel instances anyOne.
myVisitor := SPGHTMLVisitor new.
myVisitor renderer: WAStaticHtmlCanvas new.
page := kernel root.
PRCurrentContext
use: (PRContext kernel: kernel)
during: [myVisitor start: page.].
Thanks in advance

Hi Pierre-Emmanue,

I wonder why you need a new context for that?
If you subclass PRWidget you have the current context in 'self
context' and you can find out about the kernel by evaluating 'self
context kernel'.
Have a look at PRTreeWidget that does something like that already. It
doesn't use a visitor, but it queries all the information you need to
start your visitor.
Cheers,
Lukas

Thank you for your answer. In fact, at the beginning I wanted just to
test my code directly under squeak without using a Widget.

Ok. Your code for that looks fairly good. You properly define a new
browsing context looking at the root page . Was there a specific
problem with the code?

We have a problem of context when we explore the tree structure of pier
with our visitor and when we visit an internal link. We perhaps found a
solution by creating a static PRContext and by redefining the UrlOn method.
(sorry for my bad english :) )
