法律学习Tkinter 中的窗口大小调整控制面板
本文将创建一个基于 GUI 的窗口大小调整控制面板，其中会提供一个可以按高度或宽度调整窗口大小的面板。
为了创建该程序，我们首先将创建一个帮助调整窗口大小的滑动条。滑块可以在 tkinter 的ttk 库中找到。我们将首先导入“ttk”。然后，我们将启动一个需要调整大小的新窗口。
让我们先在笔记本中导入所有必需的库，然后使用滑动条设计控制栏。
示例
# Import the required Libraries
from tkinter import *
from tkinter import ttk
# Create Object
win = Tk()
# Set title
win.title("Window Resizer")
lab= Label(win, text="Window Resizer", font=('Poppins bold', 20))
#Define the geometry for the window or frame
win.geometry("500x500")
# Create a button to launch a new window
launch_button = Button(win,text = "Launch")
launch_button.pack(pady = 10)
# Add Label Frames for width, height and both
width_frame = LabelFrame(win, text = "Width")
width_frame.pack(pady = 10)
height_frame = LabelFrame(win, text = "Height")
height_frame.pack(pady = 10)
both_frame = LabelFrame(win, text = "Both")
both_frame.pack(pady = 10)
#Width Slider
width_slider = ttk.Scale(width_frame,from_ = 100,to = 500,orient = HORIZONTAL,length = 200, value = 100)
width_slider.pack(pady = 10, padx = 20)
#Height Slider
height_slider = ttk.Scale(height_frame, from_ = 100, to = 500, orient = VERTICAL,length = 200, value = 100)
height_slider.pack(pady = 10, padx = 20)
#Both Slider
both_slider = ttk.Scale(both_frame, from_ = 100,to = 500, orient = HORIZONTAL,length = 200, value = 100)
both_slider.pack(pady = 10,padx = 20)
# Keep running the window
win.mainloop()创建滑动条和控制器的 GUI 后，我们将定义会在滑动条和窗口控件中调用的不同函数。
首先，我们将创建一个函数来打开一个新窗口，控制移动将出现在该窗口中。然后，我们将定义宽度、高度和两者同时的函数。
定义函数后，函数将如下所示 −
示例
# Import the required Libraries
from tkinter import *
from tkinter import ttk
# Create Object
win = Tk()
# Set title
win.title("Window Resizer")
lab= Label(win, text="Window Resizer", font=('Poppins bold', 20))
#Define the geometry for the window or frame
win.geometry("500x500")
#Define Functions for all different events
# Open New Window
def launch_win():
global win1
win1 = Toplevel()
win1.geometry("100x100")
# Change width
def change_width(x):
win1.geometry(f"{int(width_slider.get())}x{int(height_slider.get())}")
#Change height
def change_height(x):
win1.geometry(f"{int(width_slider.get())}x{int(height_slider.get())}")
#Change both width and height
def change_both(x):
win1.geometry(f"{int(both_slider.get())}x{int(both_slider.get())}")
# Create a button to launch a new window
launch_button = Button(win,text = "Launch", command= launch_win)
launch_button.pack(pady = 10)
# Add Label Frames for width, height and both
width_frame = LabelFrame(win, text = "Width")
width_frame.pack(pady = 10)
height_frame = LabelFrame(win, text = "Height")
height_frame.pack(pady = 10)
both_frame = LabelFrame(win, text = "Both")
both_frame.pack(pady = 10)
#Width Slider
width_slider = ttk.Scale(width_frame,from_ = 100,to = 500,orient =
HORIZONTAL,length = 200, command= change_height, value=100)
width_slider.pack(pady = 10, padx = 20)
#Height Slider
height_slider = ttk.Scale(height_frame, from_ = 100, to = 500, orient =
VERTICAL,length = 200,command= change_width, value=100)
height_slider.pack(pady = 10, padx = 20)
#Both Slider
both_slider = ttk.Scale(both_frame, from_ = 100,to = 500, orient =
HORIZONTAL,length = 200,command= change_both, value=100)
both_slider.pack(pady = 10,padx = 20)
#Keep Running the window or frame
win.mainloop()输出
运行上述代码将创建一个窗口大小调整器。
