Introduction and Simple ExamplesA text widget is used for multi-line text area. The tkinter text widget is very powerful and flexible and can be used for a wide range of tasks. Though one of the main purposes is to provide simple multi-line areas,as they are often used in forms, text widgets can also be used as simple text editors or even web browsers. Furthermore, text widgets can be used to display links, images, and HTML, even using CSS styles. In most other tutorials and text books, it's hard to find a very simple and basic example of a text widget.That's why we want to start our chapter with a such an example: We create a text widget by using the Text() method. We set the height to 2, i.e. two lines and the width to 30, i.e.30 characters. We can apply the method insert() on the object T, which the Text() method had returned, to includetext. We add two lines of text. The result should not be very surprising: Let's change our little example a tiny little bit. We add another text, the beginning of the famous monologuefrom Hamlet: If we start our little script, we get a very unsatisfying result. We can see in the window only the first lineof the monologue and this line is even broken into two lines. We can see only two lines in our window, because weset the height to the value 2. Furthermore, the width is set to 30, so tkinter has to break the first line of the monologueafter 30 characters. One solution to our problem consists in setting the height to the number of lines of our monologue and set width wide enough to display the widest line completely. But there is a better technique, which you are well acquainted with from your browser and other applications: scrolling Tkinter Examples Python 3 PdfScrollbarsSo let's add a scrollbar to our window. To this purpose, Tkinter provides the Scrollbar() method. We call it with the root object as the only parameter.Text Widget with ImageIn our next example, we add an image to the text and bind a command to a text line:Python Gui Pdf
