Tkinter own text dialog?

Michi123170ByMichi123170

Can someone please tell me why this isn't working and I'm not getting the text I entered back.

 class eigene_dialoge:    def notiz_dialog(title):        notiz = "inhalt"#o(title,"r")        w_editnotiz = tk.Tk()        def cancel():            w_editnotiz.destroy        def ok():            w_editnotiz.destroy        l_wttitle = tk.Label(w_editnotiz, text="Titel:")        l_wtitle = tk.Entry(w_editnotiz)        l_wtitle.insert(0,title)        l_wtinhalt = tk.Label(w_editnotiz, text="Inhalt:")        l_winhalt = tk.Entry(w_editnotiz)        l_winhalt.insert(0,notiz.read())        l_button_save = tk.Button(w_editnotiz, text="Save" ,command=ok)        l_button_cancel = tk.Button(w_editnotiz, text="Abbrechen" ,command=cancel)        l_wttitle.pack()        l_wtitle.pack()        l_wtinhalt.pack()        l_winhalt.pack()        l_button_save.pack()        l_button_cancel.pack()               l_button_save.pack(fill="x")        l_button_cancel.pack(fill="x")        w_editnotiz.mainloop()        return [l_wtitle.get(),l_winhalt.get()] print(eigene_dialoge.notiz_dialog("test"))

Why are sorting algorithms faster in an IDE?

ByZee27

I've implemented insertion sort and merge sort in Golang, and the algorithms work. Now to my question: I wanted to check the algorithms for timing differences. In jupyter-notebook using the Go kernel, insertion sort with 10,000 elements takes 4.72 seconds, while merge sort takes 0.239 seconds. However, when I run the algorithms in an IDE…

Run a newly created shape through the form in Delphi?

ByOlzwer

I'm trying to create shapes continuously and then have them move across the image. However, I keep getting error messages about an access violation. If you have any solutions, here's the source code: procedure TForm1.Timer1Timer(Sender: TObject) var n:integer; begin Randomize; begin ShapeArray[i] := TShape.Create(Self); ShapeArray[i].Parent := Self; ShapeArray[i].SetBounds(200,30,30,200+n); end; end; procedure TForm1.Timer2Timer(Sender: TObject); begin begin…

It downloads the packages in the Python environment but refuses to install due to permission issues. Here's the error prompt at the bottom: ERROR: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied:

(1) Strings do not have a method read more. Inserting into the input field should therefore look like this instead:

l_winhalt.insert(0, notiz)

2) At the time when you read the input fields, they no longer exist.

One solution would be another sequence of operations:

# ...

result = [l_wtitle.get(), l_winhalt.get()]
w_editnotiz.mainloop()

return result

It would be even better if you were to use the traditional tkinter structure. There is only one root window for each application if you need multiple window instances, use this Frame-Widget. For building the GUI you can work object-oriented.

import tkinter as tk

class Dialogue:
  def __init__(self, window):
    self.window = window

  def cancel(self):
    self.window.destroy()

  def ok(self):
    self.window.destroy()

class NoteDialogue(Dialogue):
  def __init__(self, window, title):
    Dialogue.__init__(self, window)

    note = "Inhalt"

    title_label = tk.Label(self.window, text="Titel:")
    self.title_field = tk.Entry(self.window)
    self.title_field.insert(0, title)
    content_label = tk.Label(self.window, text="Inhalt:")
    self.content_field = tk.Entry(self.window)
    self.content_field.insert(0, note)
    save_button = tk.Button(self.window, text="Save" ,command=self.ok)
    cancel_button = tk.Button(self.window, text="Abbrechen" ,command=self.cancel)

    title_label.pack()
    self.title_field.pack()
    content_label.pack()
    self.content_field.pack()
    save_button.pack(fill="x")
    cancel_button.pack(fill="x")

  def get_inputs(self):
    return [self.title_field.get(), self.content_field.get()]

root = tk.Tk()

dialogue = NoteDialogue(root, "Test")
print(dialogue.get_inputs())

root.mainloop()
