如何在列表或字典中存储 Gtk.Calendar.get_date() 中的日期和 Gtk.TextBuffer 中该日期的文本 python
how to store in a list or dictionary the date from Gtk.Calendar.get_date() and a text from Gtk.TextBuffer for that date in python
我正在尝试在 python.As 中创建一个日历应用程序，目前我已经设法创建 Gtk.window，一个包含两页的 Gtk.Notebook（第 1 页月历，第 2 页周日历）添加到 Gtk.window。我使用了 Gtk.Calendar 作为月份，从信号 'day-selected' 我使用了一个函数到 get_date()。我还使用了 Gtk.TextView Gtk.TextBuffer 输入文本（作为注释）。
第一个问题：如何将日期与输入文本连接起来并将其存储在列表或字典中，以便稍后将其保存到文件中。
其次:我已经使用 self.calendar.set_property("show-details", True) 激活了详细信息，并定义了一个函数 self.calendar.set_detail_func(self.cal_entry) 来获取详细信息。
def cal_entry(self, calendar, year, month, date):
if self.textbuffer is not None:
self.calendar.mark_day(self.day)
由于上述功能无法正常使用，因此如何用注释（Gtk.TextBuffer中的文本）标记日期。

对于第一个问题：视情况而定，但可能是由 y/m/d
的三元组索引的字典
d = dict()
d[(2019, 10, 1)] = "your notes..."
第二个问题：详细信息的工作方式是 cal_entry(self, calendar, year, month, day) 必须 return 一个字符串才能显示在日历中的日期下方。所以你必须从上面的字典中获取文本。你可以这样做：
def cal_entry(self, calendar, year, month, day):
self.calendar.mark_day(day)
return dict.get((year, month, day))
