[PYTHON] Tkinter beginnt
Einführung
-Dies ist ein Memorandum, in dem die Verwendung von [tkinter] untersucht wurde (https://docs.python.org/ja/3/library/tk.html).
Hintergrund
- Simple Hello World Program war nicht einfach ... ――Ich möchte es nach und nach verstehen.
a-simple-hello-world-program.py
import tkinter as tk
class Application(tk.Frame):
def __init__(self, master=None):
super().__init__(master)
self.master = master
self.pack()
self.create_widgets()
def create_widgets(self):
self.hi_there = tk.Button(self)
self.hi_there["text"] = "Hello World\n(click me)"
self.hi_there["command"] = self.say_hi
self.hi_there.pack(side="top")
self.quit = tk.Button(self, text="QUIT", fg="red",
command=self.master.destroy)
self.quit.pack(side="bottom")
def say_hi(self):
print("hi there, everyone!")
root = tk.Tk()
app = Application(master=root)
app.mainloop()
Umgebung
- Windows10
- python3.8.0
Erster Schritt
- Minimales Programm, das nur ein Fenster öffnet
main.py
import tkinter as tk
root = tk.Tk()
root.mainloop()
Ausführungsergebnis
Was ich mich gefragt habe
Q. Warum bist du root?
_root()
import tkinter as tk
root = tk.Tk()
print(root._root()) # .(Punkt)Wird angezeigt
print(type(root.master), type(root)) # Class: NoneType, tkinter.Tk
F. Benötige ich tk.Tk ()?
- Schauen Sie sich Tcl / Tk an (wirklich ein wenig) Zum Einlesen der zweiten Anmerkung muss der Anwendungsprogrammierer tk.Tk () nicht explizit instanziieren.
Hello World!?
- Ändern Sie den Titel des Fensters
main.py
import tkinter as tk
root = tk.Tk()
root.title('Hello World!')
root.mainloop()
Ausführungsergebnis
Hello World!
- Fenster vergrößern
main.py
import tkinter as tk
root = tk.Tk()
root.title('Hello World!')
root.geometry('400x200')
root.mainloop()
Ausführungsergebnis
Generieren Sie eine App mit einer Klasse, die tkinter.Frame erbt
- Label mit anderem ersten Argument generieren
- self.master
- self
- Keine Argumente
App.py
import tkinter as tk
class App(tk.Frame):
def __init__(self, title="tk", *, width="300", height="200"):
super().__init__()
self.master.title(title)
self.master.geometry(f'{width}x{height}')
self.master.maxsize(self.master.winfo_screenwidth()-100, self.master.winfo_screenheight()-100)
self.create_widgets()
self.pack()
def create_widgets(self):
self.l1 = tk.Label(self.master, text='Hello World1!', fg='red', bg='pink') # .!label
self.l1.pack()
self.l2 = tk.Label(self, text='Hello World2!', fg='green', bg='greenyellow') # .!app.!label
self.l2.pack()
self.l3 = tk.Label(text='Hello World3!', fg='blue', bg='aqua') # .!label2
self.l3.pack()
if __name__ == '__main__':
myapp = App("Hello WM")
myapp.mainloop()
Ausführungsergebnis
Aha
――Der Ort, an dem das Etikett wächst, hat sich geändert --Tk class = base, App (Frame) class = frame »Bild wie dieses
Zusammenfassung
--tk.Tk () musste nicht explizit geschrieben werden.
- Das offizielle Tutorial endet, ohne zu wissen, warum Sie root übergeben.

self.l2.pack()
