tkinter user interface

Note: To get the most out of this section, follow along in a Python shell. function sets this to False. grid() method is used to specify the relative layout (position) of the For example, you can bind an event handler to a Button widget that will perform some action whenever the button is pressed: In this example, the "" event on the button widget is bound to the handle_click event handler. # Create the "Submit" button and pack it to the, # Create the "Clear" button and pack it to the, # Create a Label widget with the text from the labels list, # Entry widgets in the row whose index is idx, # Assume that this list gets updated automatically, # If the event list is empty, then no events have occurred, # and you can skip to the next iteration of the loop, # If execution reaches this point, then there is at least one, """Print the character associated to the key pressed""", # Bind keypress event to handle_keypress(), Exercise: Simulate rolling a six-sided die, Solution: Simulate rolling a six-sided die, """Convert the value for Fahrenheit to Celsius and insert the, # Create the Fahrenheit entry frame with an Entry, # Layout the temperature Entry and Label in frm_entry, # Create the conversion Button and result display Label, # Set up the layout using the .grid() geometry manager, """Save the current file as a new file. For example: fred["geometry"] = "200x100". For example: Colors can be given as the names of X colors in the rgb.txt file, or as strings This ensures that the Label widget always displays its text without chopping off any characters, even if the window size is extremely small. Due to automatic memory management, Python would normally garbage collect such unassigned objects, but Tkinter prevents that by registering every new widget internally. child widget names as the keys and the child instance objects as the 3.7.16 Documentation The Python Standard Library Graphical User Interfaces with Tk Tk/Tcl has long been an integral part of Python. If so, then itll execute some code in response. This makes it a compelling choice for building GUI applications in Python, especially for applications where a modern sheen is unnecessary, and the top priority is to quickly build something thats functional and cross-platform. It provides a robust and platform independent windowing toolkit, that is available to Python programmers using the tkinter package, and its extension, the tkinter.tix and the tkinter.ttk modules. Take the Quiz: Test your knowledge with our interactive Python GUI Programming With Tkinter quiz. pack() method applied to it. So, to get the word Hello from the text box, use "1.0" for the first index and "1.5" for the second index: To get the word World on the second line of the text box, change the line numbers in each index to 2: To get all of the text in a text box, set the starting index in "1.0" and use the special tk.END constant for the second index: Notice that text returned by .get() includes any newline characters. Caltech PGP Full Stack Development Explore Program bindings are provided in a separate module, tkinter.ttk. Note: The output of the above program is not printed in the Tkinter application window. together with it. main tkinter module, as well as the tkinter.ttk module, which provides Below, you can look at two solutions that use the .grid() geometry manager. Passing a '+' means that this function is to be added to the list You may also try using pyenv to manage multiple Python versions. Heres what the final window will look like: Now that you know what widgets you need and what the window is going to look like, you can start coding it up! "s", "sw", "w", "nw", and also "center". Youll write your own event loop in order to better understand how Tkinters event loop works. This .delete() method takes an integer argument that tells Python which character to remove. variable or textvariable option. Try widening the window generated by the previous script to see how this works. Most of the themed widgets are near drop-in replacements for their legacy counterparts, but with a more modern look. whereas Tkinter doesnt use names but object references. child widget. this binding is to replace any other bindings that this event is associated get() missing 1 required positional argument: 'index1', # Swap the order of `frame_a` and `frame_b`, Exercise: Create an Entry widget and insert some text, Solution: Create an Entry widget and insert some text, # Create a new window with the title "Address Entry Form", # Create a new frame `frm_form` to contain the Label, # and Entry widgets for entering address information, # Create the Label and Entry widgets for "First Name", # Use the grid geometry manager to place the Label and, # Entry widgets in the first and second columns of the, # Create the Label and Entry widgets for "Last Name", # Place the widgets in the second row of the grid, # Create the Label and Entry widgets for "Address Line 1", # Place the widgets in the third row of the grid, # Create the Label and Entry widgets for "Address Line 2", # Place the widgets in the fourth row of the grid, # Create the Label and Entry widgets for "City", # Place the widgets in the fifth row of the grid, # Create the Label and Entry widgets for "State/Province", # Place the widgets in the sixth row of the grid, # Create the Label and Entry widgets for "Postal Code", # Place the widgets in the seventh row of the grid, # Create the Label and Entry widgets for "Country", # Place the widgets in the eight row of the grid, # Create a new frame `frm_buttons` to contain the, # Submit and Clear buttons. During the event loop, your application checks if an event has occurred. The widget object that contains this widget. Just like with Python string slices, in order to get the entire word Hello from the text box, the end index must be one more than the index of the last character to be read. Passing the config() method the name It is a . interface to the Tk toolkit. Unsubscribe any time. Youll also need decrease() to decrease the value in value_label by one: Put increase() and decrease() in your code just after the import statement. Themed widget set introduced in Tk 8.5, providing modern alternatives The values are the corresponding Tkinter objects. The default system version is used instead. There are several ways to add widgets to a window. There are a few things that you need to do to update the program. will block other events from being processed. The layout contains a single row and two columns: To set the minimum sizes for the window and txt_edit, you can set the minsize parameters of the window methods .rowconfigure() and .columnconfigure() to 800. A widget will appear only after it has had, for example, the packers One notable criticism is that GUIs built with Tkinter look outdated. Line 15 packs the Frame into the window using .pack(). Dec 8, 2021 -- 4 Developing GUI with Python frameworks Photo by Format from Pexels No solution is complete without a great UI. when you create a widget in Tcl/Tk, it creates a Tcl command with the name How to create graphical user interfaces with TKinter and Python. This documentation will concentrate on these For example, 3.5 inches is expressed is optional, either '' or '+'. For a step-by-step walk-through of this process, check out the Python 3 Installation & Setup Guide. their values. Jun 9, 2017 at 10:34. This is meant only as an example. literals, instead. Images of different formats can be created through the corresponding subclass The two types of padding are external and internal padding. The book uses Pythons built-in IDLE editor to create and edit Python files and interact with the Python shell. You can bind any event handler to any kind of widget with .bind(), but theres a more straightforward way to bind event handlers to button clicks using the Button widgets command attribute. But the button doesnt do anything just yet. Heres an example of how the .place() geometry manager works: Heres the window that the code produces: Note that if you run this code on a different operating system that uses different font sizes and styles, then the second label might become partially obscured by the windows edge. 'gray50', 'hourglass', 'info', 'questhead', 'question', Frame widgets are great for organizing other widgets in a logical manner. Commenting Tips: The most useful comments are those written with the goal of learning from or helping out other students. instance has its own associated Tcl interpreter. For example, the following code creates two Label widgets and places them in a grid with one column and two rows: Each grid cell is 250 pixels wide and 100 pixels tall. Its for display purposes only. For more information, check out the Grid Geometry Manager section of the TkDocs tutorial. Some options and methods for menus manipulate specific menu entries. Both old and new APIs are still available. that adds custom commands to create and manipulate GUI widgets. instance. with a geometry manager. Operations which are implemented as separate commands in Tcl (like widgets, the latter are the options that are idiosyncratic to that particular labels, buttons, menus). Here are some official resources to check out: In this tutorial, you learned about the Label, Button, Entry, Text, and Frame widgets. The pack() method can be called with keyword-option/value pairs that control The official Python binary release bundles Tcl/Tk 8.6 list of options to that of a simpler widget, like a frame, is one way to Whether its trying to navigate reference documentation, trying to find However, using the full name of the widget class can lead to long variable names, so you may want to adopt a shorthand for referring to each widget type. width is no longer necessary because each frame sets .pack() to fill horizontally, overriding any width you may set. become deprecated when it is replaced with the Tk DND. So, you can think of the y argument of .place() as the number of pixels from the top of the window, and the x argument as the number of pixels from the left edge of the window. as argument names; however, calling winfo_parent() returns a find more detailed documentation on them, including in the official Tcl/Tk application, and initialize a Tcl interpreter for this widget. The immediate descendants of this widget as a dict with the defined in tkinter. By now, you have a pretty good idea of how to create a window with Tkinter, add some widgets, and control the application layout. index1 and index2 - index1 acting like startindex and index2 acting like endindex. If you want to change something, then its clear to see exactly where to do so. Both .columnconfigure() and .rowconfigure() take three essential arguments: weight is set to 0 by default, which means that the column or row doesnt expand as the window resizes. can be queried at runtime by calling the config() method without distance (see above). First, remember that the details of how individual widgets work may vary This is a string with four space-delimited elements, each of which is a legal But it doesnt do anything just yet, so you need to start writing the commands for the buttons. The module Tkinter is an interface to the Tk GUI . To continue with this article, you'll need to install the Python 3 interpreter from the official Python website. turn_red() callback. Note: Themed widgets in the tkinter.ttk module use the operating systems native look and feel by default. The width of the frame holding the buttons should not change, however. However, if you want to continue using the Python interpreter bundled with your operating system, then install the following package: This installs the Python GUI Tkinter module. How to control your application layout with. Balancing a PhD program with a startup career (Ep. In this section, youll learn how to bring your applications to life by performing actions whenever certain events occur. see the man pages and page 183 of John Ousterhouts book. Note: An event is any action that occurs during the event loop that might trigger some behavior in the application, such as when a key or mouse button is pressed. Because no anchor point was specified when .pack() was called for each Frame, theyre all centered inside of their parcels. 1 Answer. If you use threads, you may need to be aware of this. Graphical User Interface (GUI) is nothing but a desktop application which helps you to interact with the computers. Just like with Entry widgets, you can perform three main operations with Text widgets: Although the method names are the same as the Entry methods, they work a bit differently. create and manage one or more instances of a Tcl interpreter, run Tcl the modern themed widget set and API: Construct a toplevel Tk widget, which is usually the main window of an Though Only btn_open has vertical padding. master and parent are similar and sometimes used interchangeably This section is not designed to be an exhaustive tutorial on either Tk or Tkinter is not a thin wrapper, but adds a fair amount of its own logic to class, option, or method that youre using. To connect the buttons to the functions, assign the function to the buttons command attribute. event. (See the into other frames, in order to achieve the kind of layout you desire. tries to bridge. Create a modern user interface with the Tkinter Python library TKVue saves time while developing the graphical interface and makes it easier to maintain and modify the code afterward. information about each object, including its default and current values. To retrieve several characters, you need to pass a start index and an end index. pressed, it will call the destroy() method of the root window. parent/child reflects the tree-like relationship while You place five pixels of padding around each button by setting the padx and pady parameters to 5. Thats not to say you should never use .place()! On each iteration of the loop, the i-th column and row are configured to have a weight of 1. to find out which are specific to a particular widget class. Tk uses Tcls event queue to generate and process GUI events. Write a program that simulates rolling a six-sided die. reference to the image. .className.py and .baseName.py. But if you try and expand the window in any direction, then youll notice that the layout isnt very responsive: The whole grid stays at the top-left corner as the window expands. Tkinter has several strengths. consult the Tk documentation, and occasionally the Tcl documentation. appears. The bulk of the material in this tutorial has been left unchanged, and you should have no problems running the example code from the editor and environment of your choice. This is a string of the form widthxheight, where width and height are You can control Label text and background colors using the foreground and background parameters: There are numerous valid color names, including: Many of the HTML color names work with Tkinter. Heres the code for the window: With the app layout defined, you can bring it to life by giving the buttons some commands. The sticky parameter for frm_buttons is set to "ns", which forces the whole frame to expand vertically and fill the entire height of its column. Youll call its .pack() method directly on the same line of code: This might be helpful when you dont intend to refer to the widgets instance later on. (ISBN 978-0321336330). The .grid() geometry manager solves a lot of these issues, as youll see in the next section. others. To avoid this problem, use the official macOS installer. For Tk, the Since its on top, the vertical padding offsets the button down from the top of the window a bit and makes sure that theres a small gap between it and btn_save. as a y pixel coordinate in the menus coordinate system; the string "none", which indicates no menu entry at all, most often used Note: The code examples in this tutorial have all been tested on Windows, macOS, and Ubuntu Linux 20.04 with Python version 3.10. Frame widgets can be configured with a relief attribute that creates a border around the frame. There are three main operations that you can perform with Entry widgets: The best way to get an understanding of Entry widgets is to create one and interact with it. This function also needs to extract the text currently in txt_edit and write this to a file at the selected location. If youd like to learn more about the two widget types, then you can expand the collapsible section below: Its worth noting that there are currently two broad categories of widgets in Tkinter: Tkinters classic widgets are highly customizable and straightforward, but they tend to appear dated or somewhat foreign on most platforms today. As most widgets have many configuration options in common, it can be useful Similarly, you can find the available methods for a widget object using the formats such as BMP, JPEG, TIFF, and WebP, among others. # 5 pixels of horizontal and vertical padding. It is open-source and available under the Python License. The Tcl library has a C interface to Before you get into the details about laying out the visual presentation of your widgets, take a closer look at how Frame widgets work, and how you can assign other widgets to them. This is most often useful when driving the Tcl interpreter in an The widgets choice gets even more complicated when you account for a whole new set of themed widgets. You can use .get() to retrieve the text and assign it to a variable called name: You can delete text as well. inherit from). Calling .get() with a single index returns a single character. In Tkinter, you write functions called event handlers for the events that you use in your application. The A button widget is then created, and placed to the right of the label. platform independent windowing toolkit, that is available to Python programmers the display only when actively running an event loop. are used to specify the relative positioning of widgets within their container - # here are method calls to the window manager class, Modern Tkinter for Busy Python Developers. Name of the widget class. script above. For example, the following code creates a widget with a blue background, some yellow text, and a width of 50 text units: The interesting bit about Entry widgets isnt how to style them, though. The best way to insert text at the end of a Text widget is to pass tk.END to the first parameter of .insert(): Dont forget to include the newline character (\n) at the beginning of the text if you want to put it on a new line: Label, Button, Entry, and Text widgets are just a few of the widgets available in Tkinter. Its a common early mistake to leave out the geometry Write a full Python script that creates a Tkinter window with the text "Python rocks!". pages for the widget in question. Unfortunately, in the current implementation of tkinter it is not The side keyword argument of .pack() specifies on which side of the window the widget should be placed. Font sizes with They perform different tasks in the desktops, laptops and other electronic devices. classes. get() method on it, and to change its value you call the set() Tk allows you to register and unregister a callback function which will be specification, and then be surprised when the widget is created but nothing A theme is a collection of reusable style definitions, which you can think of as a Cascading Style Sheet (CSS) for Tkinter. If you want a shiny, modern interface, then Tkinter may not be what youre looking for. Legal values are the strings: "left", "center", "right", and For example, you can set the fill keyword argument to specify in which direction the frames should fill. To find out what configuration options are available on any widget, call its Tcl/Tk libraries can be built so they are not thread-aware. Its a bit long, but everything is very explicit. Exercise: Create an address entry formShow/Hide. As you widen the window, the width of the three Frame widgets grow to fill the window: Notice, though, that the Frame widgets dont expand in the vertical direction. The 2-tuple passed By Patrik Dufresne February 14, 2023 | 2 Comments | 9 min read Register or Login to like Image by: Opensource.com Assume theres a list called events that contains event objects. the root window is just . Now that you have a window, you can add a widget. Each frame is attached to window with the .grid() geometry manager: Each label is attached to its master Frame with .pack(): The important thing to realize here is that even though .grid() is called on each Frame object, the geometry manager applies to the window object. with menu.activate() to deactivate all entries, and finally. # It prints the current value of the variable. window. The remainder of this section will help you to identify the classes, For example, the code block below shows how .delete(0) deletes the first character from Entry: The text remaining in the widget is now eal Python: Note that, just like Python string objects, text in an Entry widget is indexed starting with 0. Youll put buttons on the left and right side of the label. Using an infinite loop, you can continually check if there are any event objects in events: Right now, the event loop that youve created doesnt do anything with event. Because of that, wildcard imports are considered a bad practice, which should generally be avoided unless used consciously. measured in pixels for most widgets (in characters for widgets displaying text). In some cases, it might be just what you need. Now that frm_buttons is laid out and ready to go, you can set up the grid layout for the rest of the window: These two lines of code create a grid with one row and two columns for window. do that. Some options, like bg are synonyms for common options with long names def printtext (): global e string = e.get () print string from Tkinter import * root = Tk () root.title ('Name') e = Entry (root) e.pack () e.focus_set () b = Button (root,text='okay',command=printtext) b.pack (side='bottom') root . Line 13 starts a for loop to loop over each item in the border_effects dictionary. The same keyword arguments that you use to create and style a Label will work with Button widgets. Now that the application layout is complete, add window.mainloop() to the bottom of the program and save and run the file: That looks great! First, youll create a window with a Label widget that holds a numeric value. user-interface tkinter Share Improve this question Follow edited Mar 3, 2018 at 14:07 Nae 13.9k 7 52 78 asked Apr 13, 2012 at 0:44 Damien 563 2 6 10 1 I recommend you read the book "Python and TKinter programming". When the user clicks the button, a random integer from 1 to 6 should be displayed. There should be one button with the text Roll. Tkinter has two others: Each window or Frame in your application can use only one geometry manager. is a Python function, taking one argument, to be invoked when the event occurs. Basics to Advanced - Learn It All! string (for example, 'relief') and whose values are 5-tuples. Common dialogs to allow the user to specify a file to open or save. Share your fun projects down in the comments below! The correspondence between the sticky and fill parameters is summarized in the following table: .grid() is a powerful geometry manager. Screen distances can be specified in either pixels or absolute distances. See page 160 of Ousterhouts book for details. Warning: When you work with Tkinter from a Python REPL, updates to windows are applied as each line is executed. First, import askopenfilename() from tkinter.filedialog by adding the following import to the top of your program: Next, set the command attribute of btn_opn to open_file: Save the file and run it to check that everything is working. considered after all the others, which means that matches for menu items alternative GUI frameworks and tools. For example, if youre creating a GUI interface for a map, then .place() might be the perfect choice to ensure widgets are placed at the correct distance from each other on the map. Keep in mind that your code may look different. been implemented as methods on the Wm class. platform independent windowing toolkit, that is available to Python programmers using the tkinterpackage, and its extension, the tkinter.tixand the tkinter.ttkmodules. (X11 only). Related widgets can be assigned to the same frame so that, if the frame is ever moved in the window, then the related widgets stay together. The image object can then be used wherever an image option is supported by btn_open is put in the first row and btn_save in the second row so that btn_open appears above btn_save in the layout, just you planned in your sketch. used in Tkinter. Support for Tkinter is spread across several modules. But blank windows arent very useful! If True, initialize the Tk subsystem. Since you dont know how many bytes are available for reading, you may not For the rest of this tutorial, youll use the following shorthand prefixes to name widgets: In this section, you learned how to create a window, use widgets, and work with frames. If theres no text in Entry, then the new text will always be inserted at the beginning of the widget, no matter what value you pass as the first argument. This ensures that lbl_temp is always located immediately to the right of ent_temperature.

Curated by the Real Python team. Its how to use them to get input from a user. Making the new widgets themable meant extracting most of their style information into separate objects. Labels are great for displaying some text, but they dont help you get input from a user. You can lay them out in frm_entry using the .grid() geometry manager with one row and two columns: Youve set the sticky parameter to "e" for ent_temperature so that it always sticks to the rightmost edge of its grid cell. No distinction between standard and widget-specific options is made in this The following table lists the other event fields you can access, and how To get at the toplevel appearance on different platforms than many of the classic Tk widgets. master is None because it is the main window. Running python -m tkinter from the command line should open a window The geometry manager youll likely use most often is .grid(), which provides all the power of .pack() in a format thats easier to understand and maintain. There are eight built-in, named bitmaps: 'error', 'gray25', Whenever the button is pressed, the function is executed. This ensures that the row and column expand at the same rate whenever the window is resized. You can probably find them on eBay for lower prices. Tcls syntax is similar to many shell languages, where the first word is the A distance - designating external padding on each side of the slave widget. Youll put a label directly to the right of the ent_temperature widget containing the Fahrenheit symbol () so that the user knows that the value ent_temperature should be in degrees Fahrenheit.
