![为什么我的 Gtk.Notebook 不能正确获取其标签?](https://linux22.com/image/823452/%E4%B8%BA%E4%BB%80%E4%B9%88%E6%88%91%E7%9A%84%20Gtk.Notebook%20%E4%B8%8D%E8%83%BD%E6%AD%A3%E7%A1%AE%E8%8E%B7%E5%8F%96%E5%85%B6%E6%A0%87%E7%AD%BE%EF%BC%9F.png)
我正在使用此方法保存文件:
def save(self):
file_data = ConfigParser.ConfigParser()
subjects_number = self.subjects.get_n_pages()
si = range(1, subjects_number)
for sn in si:
subject_content = self.subjects.get_nth_page(sn)
subject_name = self.subjects.get_tab_label(subject_content)
file_data.add_section(subject_name) #Line 153
pages_number = self.subjects.get_nth_page(sn)
pi = range(1, pages_number)
for pn in pi:
page_content = subject_content.get_nth_page(pn)
page_name = pages.get_tab_label(page_content)
c_buffer = page_content.get_buffer()
c_format = c_buffer.register_serialize_tagset()
serial = c_buffer.serialize(c_format, c_buffer.get_start_iter(), c_buffer.get_end_iter())
file_data.set(subject_name, page_name, serial)
with open(self.current_file, "wb") as this_file:
file_data.write(this_file)
print "File Saved:" + self.current_file
然而运行时我在终端窗口中得到了这个回溯:
Traceback (most recent call last):
File "/home/nja/notetaker/notetaker/NotetakerWindow.py", line 251, in on_btn_save_clicked
self.save()
File "/home/nja/notetaker/notetaker/NotetakerWindow.py", line 153, in save
file_data.add_section(subject_name)
File "/usr/lib/python2.7/ConfigParser.py", line 260, in add_section
if section.lower() == "default":
AttributeError: 'Label' object has no attribute 'lower'
这些方法在小部件中创建选项卡Gtk.Notebook()
:
def add_page(self, pages = None, label = None):
if pages is None:
pages = self.get_pages()
if label is None:
label = "New Page"
textview = Gtk.TextView()
textbuffer = textview.get_buffer()
pages.append_page(textview, Gtk.Label(label))
self.window.show_all()
def add_subject(self, label = None):
if label is None:
label = "New Subject"
pages = Gtk.Notebook()
pages.set_tab_pos(Gtk.PositionType.RIGHT)
pages.set_scrollable(True)
self.add_page(pages)
self.subjects.append_page(pages, Gtk.Label(label))
self.window.show_all()
我需要做什么才能解决这个错误?
答案1
self.subjects.get_tab_label(subject_content)
获取一个 Gtk.Label 实例但file_data.add_section
需要一个字符串作为参数。
使用
subject_name = self.subjects.get_tab_label(subject_content).get_text()
