[wxPython] linking from wxListbox to wxHTML control

wxPython Users
1

I want to be able click on a listbox item and use the text in it to jump to a
tag I have inserted in a HTML control.

I'm doing this for the gnuMed open source medical record project for the
DrugAnnual I'm writing, I'm very slowly getting up to speed in python! and
find the wxPython doc's difficult to interpret because of lack of concrete
examples.

Could a generous soul give me a few pointers.

Thanks in anticipation.

Try html.LoadPage( '#tag' ) or html.SetPage( '#tag' ) after actual page is loaded.

Thanks for the reply

Loadpage(#tag) froze the program into an endless cycle of error messages that
couldn't load the page. SetPage set the whole html page to the name of the
tag and I lost the previous html.

Any other ideas?

Hi,

Loadpage(#tag) froze the program into an endless cycle of error
messages that couldn't load the page.

It would be helpful if you could tell us *what* error messages, so
that I can try to fix the bug.

thanks,
Vaclav

I don't think this an actual bug.

What happened in my code was that I read the name of the string for the row
the listcontrol had been clicked on and passed this to the LoadPage and this
generated a 'HTML anchor does not exist ' or something similar
and then the list box event triggered again evey time I moved the mouse to
click <OK> to the error message.

I had put this code:<B><name='#Composition'>Composition</B> in my HTML
document as the tag to jump to but this may too be wrong.

My problem with not understanding the whole thing. Unfortunately I don't have
a computer programmer trained background. I'm in General Practice in
australia and trying to learn wxPython/python to participate in the gnuMed
medical records project (www.gnumed.net) , so though I've been quite
proficient in Visual Basic for many years, I'm finding wxPython slow going as
I have difficulty understanding the format of the documentation which doesn't
make much sense to my poor brain without a concrete code example to show me
how to use the syntax

Richard, all you need to do is create a "link clicked" event and send it
to your wxHtml.Window (or call your OnLinkClicked(linkinfo) method
directly. (Just read the documentation on wxHtmlLinkInfo how to set the
anchor / reference in the event parameter))

Haven'y got the docu here right now, if you can't figure out how to post
such an event from the demo, let me know)

Your HTML is wrong. You should have used:

<B><A NAME="Composition">Composition</A></B>

Case doesn't matter for the tags <B>, </B>, <A NAME= and </A>

If you put a link at the top of your .html file like:

<A HREF="#Composition">Composition</A>

then you can test whether the link is actually working with a plain browser
before trying it with wxHTML.
