Re: [pygtk] Quick notebook question...
Hi Tom & Brian.
That was exactly what I was looking for. Works perfectly!!
Many thanks to both of you.

Hi all.
Quick question regarding notebook signals:
I have an app with a notebook. I need to detect when a user switches to
another page.
Problem is this - when I detect the 'switch_page' signal and use
notebook.get_current_page() I'm getting the page that the user *was *on.
The other signals like 'switch_page' and 'change_current_page' don't
seem to be being fired at all. I need a way to detect the page the
user has selected after he has switched to it.
How is this done please?
Today seems to be my day for sharing ugly solutions with the list...
here's what I do:
def hackish_notebook_switcher_handler (*args):
# because the switch page signal happens before switching...
# we'll need to look for the switch with an idle call
gobject.idle_add(self.notebookChangeCB)
def notebookChangeCB (*args):
page=self.notebook.get_current_page()
# Do something with the page...
self.notebook.connect('switch-page',hackish_notebook_switcher_handler)
Yeah, as I said not pretty.
Knowing myself, I imagine I looked pretty hard for a better solution
before implementing that, so this may be what you have to do.
If not, someone please show me the better way too!
Tom
Here is how we do it without a hack.
self.notebook.connect("switch-page", self.switch_page)
def switch_page(self, notebook, page, page_num):
"""callback function changes the current_page setting in the term
structure"""
dprint("TERMINAL: switch_page; page_num = %d" %page_num)
self.term.current_tab = self.term.visible_tablist[page_num]
if self.term.auto_scroll[self.term.current_tab]:
self.scroll_current_view()
return
You should be able to decipher the above code snipit without more
explanation. We have a number of tabs that may or may not be visible.
The pygtk reference page:
http://www.pygtk.org/pygtk2reference/class-gtknotebook.html
and the pertinent info:
The "switch-page" gtk.Notebook Signal
def callback(notebook, page, page_num, user_param1, ...)
notebook :
the notebook that received the signal
page :
the new current page
page_num :
the index of the new current page
user_param1Â :
the first user parameter (if any) specified with the connect() method
... :
additional user parameters (if any)
The "switch-page" signal is emitted when the notebook page is changed.
Note the page parameter is a GPointer and not usable within PyGTK. Use
the page_num parameter to retrieve the new current page using the
get_nth_page() method.
