Explains key concepts, and illustrates recommended approaches using the modern API. ISBN Tcl is a dynamic interpreted programming language, just like Python. Though it can be used on its own as a general-purpose programming language, it is most commonly embedded into C applications as a scripting engine or an interface to the Tk toolkit.
The Tcl library has a C interface to create and manage one or more instances of a Tcl interpreter, run Tcl commands and scripts in those instances, and add custom commands implemented in either Tcl or C. Each interpreter has an event queue, and there are facilities to send events to it and process them.
Each Tk object embeds its own Tcl interpreter instance with Tk loaded into it. Themed Tk Ttk is a newer family of Tk widgets that provide a much better appearance on different platforms than many of the classic Tk widgets. Ttk is distributed as part of Tk, starting with Tk version 8.
Python bindings are provided in a separate module, tkinter. Internally, Tk and Ttk use facilities of the underlying operating system, i. When your Python application uses a class in Tkinter, e. Support for Tkinter is spread across several modules. Most applications will need the main tkinter module, as well as the tkinter.
The Tk class is instantiated without arguments. This creates a toplevel widget of Tk which usually is the main window of an application. Each instance has its own associated Tcl interpreter. The Tcl function is a factory function which creates an object much like that created by the Tk class, except that it does not initialize the Tk subsystem.
An object created by the Tcl object can have a Toplevel window created and the Tk subsystem initialized by calling its loadtk method. Themed widget set introduced in Tk 8. It is automatically imported by the main tkinter module, and should never be used directly by application programmers.
It is usually a shared library or DLL , but might in some cases be statically linked with the Python interpreter. Based on tkinter. Symbolic constants that can be used in place of strings when passing various parameters to Tkinter calls. Automatically imported by the main tkinter module.
This will become deprecated when it is replaced with the Tk DND. Better alternatives for most can be found in tkinter. This section is not designed to be an exhaustive tutorial on either Tk or Tkinter.
For that, refer to one of the external resources noted earlier. Instead, this section provides a very quick orientation to what a Tkinter application looks like, identifies foundational Tk concepts, and explains how the Tkinter wrapper is structured. After the imports, the next line creates an instance of the Tk class, which initializes Tk and creates its associated Tcl interpreter.
It also creates a toplevel window, known as the root window, which serves as the main window of the application. The frame is fit inside the root window. The next line creates a label widget holding a static text string. The grid method is used to specify the relative layout position of the label within its containing frame widget, similar to how tables in HTML work. A button widget is then created, and placed to the right of the label. When pressed, it will call the destroy method of the root window.
Finally, the mainloop method puts everything on the display, and responds to user input until the program terminates. A Tkinter user interface is made up of individual widgets.
Each widget is represented as a Python object, instantiated from classes like ttk. Frame , ttk. Label , and ttk. Widgets are arranged in a hierarchy. The label and button were contained within a frame, which in turn was contained within the root window. When creating each child widget, its parent widget is passed as the first argument to the widget constructor. Widgets have configuration options , which modify their appearance and behavior, such as the text to display in a label or button.
Different classes of widgets will have different sets of options. What Is Pandas In Python? Everything You Need To Know. Download Python For Machine Learning. Frequently Asked Questions.
