Tkinter. Press Enter in Entry box. Append to Text box. How?
events, python, python-3.x, tkinter
Solution
So you're using a `tkinter.Text` box, which supports the `.insert` method. Let's use it!
def __init__(self,form):
# Lots of your code is duplicated here, so I'm just highlighting the main parts
button1 = Button(form, text='Button1', command = self.addchat)
self.textbox = textbox1 # to make it accessible outside your __init__
self.textarea = textarea1 # see above
form.bind("<Return>", lambda x: self.addchat())
# this is the magic that makes your enter key do something
def addchat(self):
txt = self.textbox.get()
# gets everything in your textbox
self.textarea.insert(END,"\n"+txt)
# tosses txt into textarea on a new line after the end
self.textbox.delete(0,END) # deletes your textbox text
Problem
I am making a chat program and decided to use Tkinter for the interface. What I wanna do is a breeze in C# but Tkinter is new to me. Basically I have a form with a Entry control and a Text control. I want to know how to append text from the Entry control to the Text control after the user presses Enter. Here's my code so far: ``` from tkinter import * class Application: def hello(self): msg = tkinter.messagebox.askquestion('title','question') def __init__(self, form): form.resizable(0,0) form.minsize(200, 200) form.title('Top Level') # Global Padding pady and padx pad_x = 5 pad_y = 5 # create a toplevel menu menubar = Menu(form) #command= parameter missing. menubar.add_command(label="Menu1") #command= parameter missing. menubar.add_command(label="Menu2") #command= parameter missing. menubar.add_command(label="Menu3") # display the menu form.config(menu=menubar) # Create controls label1 = Label(form, text="Label1") textbox1 = Entry(form) #command= parameter missing. button1 = Button(form, text='Button1') scrollbar1 = Scrollbar(form) textarea1 = Text(form, width=20, height=10) textarea1.config(yscrollcommand=scrollbar1.set) scrollbar1.config(command=textarea1.yview) textarea1.grid(row=0, column=1, padx=pad_x, pady=pad_y, sticky=W) scrollbar1.grid(row=0, column=2, padx=pad_x, pady=pad_y, sticky=W) textbox1.grid(row=1, column=1, padx=pad_x, pady=pad_y, sticky=W) button1.grid(row=1, column=2, padx=pad_x, pady=pad_y, sticky=W) form.mainloop() root = Tk() Application(root) ```
