In gtk notebook page_num(child) being a widget
Returns : the index of the page containing child, or -1
So here is the problem:
Added button to tab for close so I need the page the button is on since the
button grabs focus rather than the tab. I tried emit back to parent and that
failed to produce anything.
The code segements:
Creation:
#--------------------------------------------------------------------------
def new_page(self, arg, filename):
self.z = self.z + 1
# create scroller, gtksourceview, buffer and set mime
scroller = gtk.ScrolledWindow()
scroller.set_policy(gtk.POLICY_AUTOMATIC, gtk.POLICY_AUTOMATIC)
bufferS = gtksourceview.SourceBuffer()
manager = gtksourceview.SourceLanguagesManager()
if arg:
type = gnomevfs.get_mime_type(arg)
language = manager.get_language_from_mime_type(type)
else:
language = manager.get_language_from_mime_type('text')
bufferS.set_language(language)
view = gtksourceview.SourceView(bufferS)
scroller.add(view)
# set defaults for gtksourceview and buffer
bufferS.set_highlight(self.HIGHLIGHT)
bufferS.set_check_brackets(self.CHECK_BRACKETS)
view.set_show_line_numbers(self.SHOW_LINE_NUMBERS)
view.set_show_margin(self.SHOW_MARGIN)
view.set_auto_indent(self.AUTO_INDENT)
view.set_tabs_width(int(self.TABS_WIDTH))
view.set_insert_spaces_instead_of_tabs(self.INSERT_SPACES_INSTEAD_OF_TABS)
view.set_margin(int(self.MARGIN))
# add close button
image = gtk.Image()
image.set_from_file("data/images/close.png")
btn = gtk.Button()
btn.add(image)
btn.connect('clicked',self.on_close_btn)
#btn.set_size_request(16,16)
# add label
hbox = gtk.HBox(False,3)
if not arg:
self.key[self.z] = gtk.Label(filename)
else:
self.key[self.z] = gtk.Label(filename.rsplit('/',1)[1])
hbox.add(self.key[self.z])
hbox.add(btn)
hbox.show_all()
# load and set text
if arg:
try:
bufferS.begin_not_undoable_action()
f = open(arg, 'r')
bufferS.set_text(f.read())
f.close()
bufferS.end_not_undoable_action()
except:
print 'File Error: '+arg
else:
bufferS.set_text('')
# populate tree
iter = None
iter = self.mod.append(iter)
if arg:
self.mod.set(iter,0, arg)
else:
self.mod.set(iter,0, filename)
self.mod.set(iter,1, self.key[self.z].get_text())
self.mod.set(iter,2, view)
self.mod.set(iter,3, bufferS)
self.mod.set(iter,4, self.key[self.z])
self.view = view
self.bufferS = bufferS
# add page
page = self.mdi_book.append_page(scroller,hbox)
self.mdi_book.show_all()
# switch to page
self.mdi_book.set_current_page(page)
Callbacks:
#--------------------------------------------------------------------------
def on_close_btn(self, widget):
p = self.mdi_book.page_num(widget)
self.on_update_tree('delete')
self.mdi_book.remove_page(p)
#--------------------------------------------------------------------------
def on_close(self, widget):
p = self.mdi_book.get_current_page()
self.on_update_tree('delete')
self.mdi_book.remove_page(p)
