метод destroy () в Tkinter | питон

Tkinter поддерживает различные методы для выполнения различных задач. Это также предлагает некоторый универсальный метод.

destroy() — это универсальный метод виджетов, т.е. мы можем использовать этот метод с любым из доступных виджетов, а также с основным окном tkinter.

Синтаксис:

Этот метод можно использовать с методом after () .

Код № 1: метод destroy () передан как команда

# импорт только этих функций
# которые нужны

from tkinter import *

from tkinter.ttk import *

# создание окна tkinter

# Создание кнопки. В этом метод уничтожения передается
# как команда, так как только кнопка 1 нажата root
# окно будет уничтожено

btn1 = Button(root, text = «Button 1» , command = root.destroy)

# Создание кнопки. В этом метод уничтожения передается
# как команда, так как только кнопка 2 нажата
# кнопка 1 будет уничтожена

btn2 = Button(root, text = «Button 2» , command = btn1.destroy)

# бесконечная петля
mainloop()

Выход:

Как вы можете заметить, в приведенном выше коде команда, переданная в кнопку-2, должна уничтожить кнопку-1, поэтому, как только вы нажмете кнопку-2, кнопка-2 будет уничтожена.

Код № 2: метод destroy () с методом after ()

# импорт только этих функций
# которые нужны

from tkinter import *

from tkinter.ttk import *

# создание окна tkinter

# Создание кнопки. В этом метод уничтожения передается
# как команда, так как только кнопка 1 нажата root
# окно будет уничтожено

btn1 = Button(root, text = «Button 1» )

# Создание кнопки. В этом метод уничтожения передается
# как команда, так как только кнопка 2 нажата
# кнопка 1 будет уничтожена

btn2 = Button(root, text = «Button 2» )

# после уничтожения метода button-1
# и кнопка-2 через определенное время

btn1.after( 3000 , btn1.destroy)

btn2.after( 6000 , btn2.destroy)

# бесконечная петля
mainloop()

Выход:
Из вывода вы можете увидеть, что оба виджета уничтожаются через определенный промежуток времени, и только корневое окно останется пустым.

Примечание: есть другой доступный метод quit() который не уничтожает виджеты, но выходит из интерпретатора tcl / tk, то есть останавливает mainloop () .

Tkinter destroy all windows

Tkinter supports a variety of methods to perform various tasks. It also offers some universal method.

destroy() is a universal widget method i.e we can use this method with any of the available widgets as well as with the main tkinter window.

Syntax:

This method can be used with after() method.

Code #1: destroy() method passed as command

Output:

As you may observe, in above code that the command that is passed in button-2 is to destroy button-1 so as soon as you press button-2, button-2 will get destroyed.

Code #2:destroy() method with after() method

Output:
From output you may see that both the widgets are destroyed after a certain time limit and only root window will be left empty.

Note: There is another method available quit() which do not destroy widgets but it exits the tcl/tk interpreter i.e it stops the mainloop().

How to delete Tkinter widgets from a window?

I have a list of tkinter widgets that I want to change dynamically.

How to delete the widgets from the window?

8 Answers 8

You can call pack_forget to remove a widget (if you use pack to add it to the window).

If you use pack_forget , you can later show the widget again calling pack again. If you want to permanently delete it, call destroy on the widget (then you won’t be able to re-add it).

If you use the grid method, you can use grid_forget or grid_remove to hide the widget.

One way you can do it, is to get the slaves list from the frame that needs to be cleared and destroy or «hide» them according to your needs. To get a clear frame you can do it like this:

You should call grid_slaves() , pack_slaves() or slaves() depending on the method you used to add the widget to the frame.

You simply use the destroy() method to delete the specified widgets like this:

Using this you can completely destroy the specific widgets.

You say that you have a list of widgets to change dynamically. Do you want to reuse and reconfigure existing widgets, or create all new widgets and delete the old ones? It affects the answer.

If you want to reuse the existing widgets, just reconfigure them. Or, if you just want to hide some of them temporarily, use the corresponding «forget» method to hide them. If you mapped them with pack() calls, you would hide with pack_forget() (or just forget() ) calls. Accordingly, grid_forget() to hide gridded widgets, and place_forget() for placed widgets.

If you do not intend to reuse the widgets, you can destroy them with a straight destroy() call, like widget.destroy() , to free up resources.

You can use forget method on the widget

Tkinter escape binding not destroying

I am trying to learn tkinter and the idea that I have requires it to be in fullscreen. Before making it fullscreen, however I wanted to make sure I could close the window using escape. So through other questions similar to this one on Stack Overflow I have been trying to get it to destroy the tkinter window when I hit escape. To me this seems like it should work but I am getting an exception when I hit escape:

This is confusing for me because I don’t think I am calling any arguments at all let alone 2. I have added a quit button which calls the close method I made and that works but using escape doesn’t seem to. I have supplied my code for clarity. I know this is similar to a lot of questions on here but I have tried everything and nothing seems to be working for me. Thanks in advance!

When you bind a function to an event, tkinter will always pass an event object to that function. The destroy function takes no arguments, which means you can’t bind directly to it. You need to bind to a function that will accept the event object as an argument.

Since you already have a function, you can give it an optional named argument so that you can continue to call your function without the argument, but it can also be used in a binding:

You could also use an anonymous function:

bindtags ( self , tagList = None )

Set or get the list of bindtags for this widget.

With no argument return the list of all bindtags associated with this widget. With a list of strings as argument the bindtags are set to this list. The bindtags determine in which order events are processed (see bind).

bind ( self , sequence = None , func = None , add = None )

Bind to this widget at event SEQUENCE a call to function FUNC.

SEQUENCE is a string of concatenated event patterns. An event pattern is of the form where MODIFIER is one of Control, Mod2, M2, Shift, Mod3, M3, Lock, Mod4, M4, Button1, B1, Mod5, M5 Button2, B2, Meta, M, Button3, B3, Alt, Button4, B4, Double, Button5, B5 Triple, Mod1, M1. TYPE is one of Activate, Enter, Map, ButtonPress, Button, Expose, Motion, ButtonRelease FocusIn, MouseWheel, Circulate, FocusOut, Property, Colormap, Gravity Reparent, Configure, KeyPress, Key, Unmap, Deactivate, KeyRelease Visibility, Destroy, Leave and DETAIL is the button number for ButtonPress, ButtonRelease and DETAIL is the Keysym for KeyPress and KeyRelease. Examples are for pressing Control and mouse button 1 or for pressing A and the Alt key (KeyPress can be omitted). An event pattern can also be a virtual event of the form where AString can be arbitrary. This event can be generated by event_generate. If events are concatenated they must appear shortly after each other.

FUNC will be called if the event sequence occurs with an instance of Event as argument. If the return value of FUNC is «break» no further bound function is invoked.

An additional boolean parameter ADD specifies whether FUNC will be called additionally to the other bound function or whether it will replace the previous function.

Bind will return an identifier to allow deletion of the bound function with unbind without memory leak.

If FUNC or SEQUENCE is omitted the bound function or list of bound events are returned.

bind_all ( self , sequence = None , func = None , add = None )

Bind to all widgets at an event SEQUENCE a call to function FUNC. An additional boolean parameter ADD specifies whether FUNC will be called additionally to the other bound function or whether it will replace the previous function. See bind for the return value.

grid_bbox ( self , column = None , row = None , col2 = None , row2 = None )

Return a tuple of integer coordinates for the bounding box of this widget controlled by the geometry manager grid.

If COLUMN, ROW is given the bounding box applies from the cell with row and column 0 to the specified cell. If COL2 and ROW2 are given the bounding box starts at that cell.

The returned integers specify the offset of the upper left corner in the master widget and the width and height.
