for i in list:
q=tkinter.simpledialog.askstring(text="",prompt=i)
when I searched related questions I did not see an answer for Python, yes Django, android available but how can we implement askstring
dialog box?
a related function is a body() I cannot find a way to use it and resize the dialog box.
CodePudding user response:
To change the width and height of Dialog
you can do this: call .geometry
in the body
method:
from tkinter import Tk
from tkinter.simpledialog import Dialog
class MyDialog(Dialog):
def __init__(self, parent, title=None, width=300, height=200):
# all variables should be initialized before calling
# `super` because it calls .wait_window
self.width = width
self.height = height
super().__init__(parent, title)
def body(self, master):
self.geometry(f'{self.width}x{self.height}')
root = Tk()
root.withdraw()
MyDialog(root)
CodePudding user response:
Well if you want to change the geometry of tkinter.simpledialog.ask[string, integer, float]
then it has to be done in a way like this:
from tkinter import Tk, Button
from tkinter.simpledialog import askstring, Dialog
def change_geometry():
widget = root.winfo_children()[-1]
if isinstance(widget, Dialog):
widget.geometry('500x500')
def show_dialog():
root.after(10, change_geometry)
return askstring('Title', 'prompt', parent=root)
root = Tk()
root.geometry('300x200')
Button(root, text='ask string', command=show_dialog).pack()
root.mainloop()
Have to schedule a call after opening the dialog to a function that will get the children of the root window and as the dialog's parent is set as root (also automatically but better be explicit) then it will also appear in that list, it should be the last one but there is a check in place to check if it actually is an instance of Dialog
(since Dialog
is somewhere up the inheritance chain and it inherits from Toplevel
which has the .geometry
method which allows to change the geometry of the dialog).
