Create a 'close/exit' option for a child frame that is created using tkinter in python -

-

i have created script using tkinter, brings child frame when press button. frame occupies full screen size on mac laptop. need create option exit/ or close new frame. best option that?

-thanks 

from tkinter import * import tkfont class app(frame):   def __init__(self, *args, **kwargs):     frame.__init__(self, *args, **kwargs)     self.apple = button(self,                      text="apple", command=self.write_apple)     self.apple.pack(side=left)  def write_apple(self):     self.customfont = tkfont.font(family="helvetica", size=80)     t = toplevel(self)     t.overrideredirect(true)     t.geometry("{0}x{1}+0+0".format(root.winfo_screenwidth(), root.winfo_screenheight()))     l = label(t, text="this green apple.",font=self.customfont)     l.pack(side="top", fill="both", expand=true)  if __name__ == "__main__":     root = tk()     main = app(root)     main.pack(side="top", fill="both", expand=true)     root.mainloop()

this solution handles case multiple instances of toplevel created:

from tkinter import * import tkfont class app(frame):     def __init__(self, *args, **kwargs):         frame.__init__(self, *args, **kwargs)         self.apple = button(self,                             text="apple", command=self.write_apple)         self.apple.pack(side=left)         self.top_dict = dict()      def destroy_top(self, event):         # event.widget instance of label clicked         # instance of toplevel         top = self.top_dict[event.widget]         # destroy instance of toplevel         top.destroy()         # remove instance of toplevel list         del self.top_dict[event.widget]      def write_apple(self):         self.customfont = tkfont.font(family="helvetica", size=80)         # create instance of toplevel         top = toplevel(self)         top.geometry("{0}x{1}+0+0".format(root.winfo_screenwidth(), root.winfo_screenheight()))         label = label(top, text="this green apple.",font=self.customfont)         label.pack(side="top", fill="both", expand=true)         # bind destroy_top method mouse-button-1 click         label.bind('<button-1>', self.destroy_top)         # save instance of toplevel using label key         self.top_dict[label] = top  if __name__ == "__main__":     root = tk()     main = app(root)     main.pack(side="top", fill="both", expand=true)     root.mainloop()

note: @bryan oakley noted, removing call overrideredirect adds window decorations instance of toplevel.

i have order , ordersearch models. in order list (actionindex) gridview there filtering , sorting. on of columns in order order_total (sum of products in order). i need implement sum of order_total in gridview. if manually counting activedataprovider->getmodels() array_map spend 3 seconds 3000 orders (localhost). don't want miss time. i see 2 ways make faster: create cache every filter , update lifetime (horrible) the interesting can right in ordersearch->search() method $query method. don't understand how can pass in controller. example of code 2nd way: class ordersearch extends order { public $totalsum; public function search($params) { $query = order::find(); $dataprovider = new activedataprovider([ 'query' => $query, ]); $this->load($params); $this->totalsum = $query->sum('order_total'); // works fast return $dataprovider; } } after i

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course,
