Python Tkinter 缩放问题

问题描述 投票：0回答：2

我是编程新手，我正在尝试为 OpenCv 应用程序做一些 Python Tkinter GUI。我的问题：我在 Tkinter 中创建了一个根窗口，并向其中添加了 2 个框架。框架中有 2 个按钮和 2 个组合框下拉菜单。当我在显示器上查看 GUI 时，一切都完美居中等等。现在，当我在笔记本电脑屏幕上查看 GUI 时，一切都缩放不同（显示器和笔记本电脑在 1920x1080 像素上运行）。有没有办法将小部件固定在框架中，这样我在哪个屏幕上查看 GUI 就无关紧要了？

代码：

# Hauptfenster erstellen
root = tk.Tk()
root.title("KI Blattanalyse")

#Blatt Icon als Software Symbol
icon = Image.open('Logo\\ICON.png')
photo = ImageTk.PhotoImage(icon)
root.iconphoto(True, photo)
root.photo = photo

# Menüleiste erstellen
menubar = tk.Menu(root)

#Datei Menü zum Beenden der Anwendung
file_menu = tk.Menu(menubar, tearoff=0)
file_menu.add_command(label="Beenden", command=on_exit)
menubar.add_cascade(label="Datei", menu=file_menu)

#Features Menü, um die Auswertungen der Software anzeigen zu lassen
feature_menu = tk.Menu(menubar, tearoff=0)
feature_menu.add_command(label="Durchschnittliche Blattfarbe", command = open_page_one)
feature_menu.add_command(label="Anzahl der Blätter", command = open_page_two)
feature_menu.add_command(label="Fläche der Blätter", command = open_page_three)
feature_menu.add_command(label="Substrate", command = open_page_four)
feature_menu.add_command(label="Pflanzen", command = open_page_five)
menubar.add_cascade(label="Features", menu=feature_menu)

#Definition der Frames auf der Startseite
#Linkes Frame
frame_left = LabelFrame(root, frame_styles, text="Aufnahme starten")
frame_left.pack(fill = "both", expand=True)
frame_left.place(rely=0.10, relx=0.05, relheight=0.80, relwidth=0.4)
#Rechtes Frame
frame_right = LabelFrame(root, frame_styles, text="Aufnahme")
frame_right.pack(fill = "both", expand=True)
frame_right.place(rely=0.10, relx=0.50, relheight=0.80, relwidth=0.45)

#Knopf zum Starten der Aufnahme
button_recordpic = tk.Button(frame_left, text_styles, text="RECORD PICTURE", command=lambda: record_picture(aruco_dict, mtx, dist, newcameramtx), height=5, width=20) 
button_recordpic.grid(row = 1, column = 1, pady = 30, sticky = "NSEW")
 
#Knopf zum Kameracheck
button_cameracheck = tk.Button(frame_left, text_styles, text="CAMERA CHECK", command=lambda: cam_check(aruco_dict, mtx, dist, newcameramtx), height=5, width=20)
button_cameracheck.grid(row = 2, column = 1, pady = 30, sticky = "NSEW")

#Dropdown Menü im linken Frame, um die Box auszuwählen
combo_box_setbox_label = tk.Label(frame_left, text="Choose a box")
combo_box_setbox_label.grid(row = 3)
combo_box_setbox = ttk.Combobox(frame_left, state ="readonly", values=["Box 1", "Box 2", "Box 3", "Box 4", "Box 5"])
combo_box_setbox.bind("<<ComboboxSelected>>", selection_box)
combo_box_setbox.grid(row = 4)

#Dropdown Menü im linken Frame, um die Aufnahme auszuwählen
combo_box_record_label = tk.Label(frame_left, text="Choose a record date")
combo_box_record_label.grid(row = 3, column = 2, sticky = "NSEW")
combo_box_record = ttk.Combobox(frame_left, state="readonly", values = check_record_folder())
combo_box_record.bind("<<ComboboxSelected>>", selection_record)
combo_box_record.grid(row = 4, column = 2, sticky = "NSEW")

#Label erstellen und Bild einfügen
label = Label(frame_right)
label.pack()


#Menüleiste dem Hauptfenster zuweisen
root.config(menu=menubar)

#Fenster maximieren
root.state('zoomed')

#Standardgröße im Fenstermodus
root.geometry("1920x1080")

#Hauptloop starten
root.mainloop()

我尝试通过谷歌搜索该错误，但并没有真正找到对我有帮助的东西。

为了使 GUI 更好地响应不同的屏幕尺寸，请考虑使用几何管理器（例如 pack 或 grid）来更动态地处理大小调整和缩放。使用这些管理器，您可以指定小部件应如何扩展和填充可用空间。

这是使用网格几何管理器的代码的修改版本：

import tkinter as tk
from tkinter import ttk
from tkinter import Label, LabelFrame
from PIL import Image, ImageTk

def on_exit():
    root.destroy()

def open_page_one():
    # Add your logic for opening page one here
    pass

def open_page_two():
    # Add your logic for opening page two here
    pass

def open_page_three():
    # Add your logic for opening page three here
    pass

def open_page_four():
    # Add your logic for opening page four here
    pass

def open_page_five():
    # Add your logic for opening page five here
    pass

def record_picture(aruco_dict, mtx, dist, newcameramtx):
    # Add your logic for recording a picture here
    pass

def cam_check(aruco_dict, mtx, dist, newcameramtx):
    # Add your logic for camera check here
    pass

def selection_box(event):
    # Add your logic for handling box selection here
    pass

def selection_record(event):
    # Add your logic for handling record selection here
    pass

def check_record_folder():
    # Add your logic for checking record folder here
    return ["Record 1", "Record 2", "Record 3"]  # Dummy data, replace with your implementation

您好，非常感谢您的快速答复。效果很好！我想以全屏模式显示我的 GUI，所以现在框架与按钮一样宽（我丢失了 relheight 和 relwidth）。有没有办法将框架扩展到整个屏幕？
