[英]populate scrolled text window with Combobox value (python)
I'm trying to build a GUI in Python where a scrolled text window is populated with one or more values selected from a Combobox.我正在尝试在 Python 中构建一个 GUI,其中滚动文本 window 填充了从 Combobox 中选择的一个或多个值。
eg if the values in the Combobox are 1, 2, 3, 4. if I click 1 it appears in the scrolled text window, then if I clicked 2 that is also added to the scrolled text window without erasing the previous selection.例如,如果 Combobox 中的值是 1、2、3、4。如果我单击 1,它会出现在滚动文本 window 中,然后如果我单击 2,它也会添加到滚动文本 Z05B8C745CBD96FBF2F4Z4C1 中而没有时代。
Can anyone help?任何人都可以帮忙吗? Below is the code I have so far.
以下是我到目前为止的代码。
#Library imports
from tkinter import *
from tkinter.ttk import *
from tkinter import scrolledtext
#window geometry
window = Tk()
window.geometry('180x220')
window.title('DFC Selector')
#Window Text
lbl = Label(window, text = "Select DFC", font = ("Arialbold",11))
lbl.grid(column=0, row=0)
# Read values from file
fcode = []
with open('DFCs.txt') as inFile:
fcode = [line for line in inFile]
fcode = sorted(fcode)
#Combo box
combo = Combobox(window,width=25)
combo['values']= (fcode)
combo.current(1)
combo.grid(column=0, row=2)
#Text window
txt = scrolledtext.ScrolledText(window,command=clicked,width=20,height=10)
txt.grid(pady=15,padx=10,column=0,row=3)
#Fault code selection to text window
def clicked():
txt.configure(text=combo.get)
#Start GUI
window.mainloop()
use txt.insert()
to insert text into Text and use end
as a parameter to insert at the end使用
txt.insert()
将文本插入 Text 并使用end
作为参数插入到末尾
from tkinter import *
from tkinter.ttk import *
from tkinter import scrolledtext
def clicked(event):
txt.insert("end", var.get()+'\n')
#window geometry
window = Tk()
window.geometry('180x220')
window.title('DFC Selector')
#Window Text
lbl = Label(window, text = "Select DFC", font = ("Arialbold",11))
lbl.pack()
# Read values from file
fcode = ['Hello', 'Random', 'BSAE']
var = StringVar()
#var.trace('w', insert)
#Combo box
combo = Combobox(window,width=25, textvariable=var, state="readonly")
combo.bind("<<ComboboxSelected>>", clicked)
combo['values']= (fcode)
combo.current(1)
combo.pack()
#Text window
txt = scrolledtext.ScrolledText(window,width=20,height=10)
txt.pack()
#Fault code selection to text window
#Start GUI
window.mainloop()
