Tk provides the tk.StringVar() to create objects that act like a string, but in order to assign or read a value we need to use the set() and get() methods. But when our application requires to both read the user input and write new text into the textbox very often, then it would be more suitable to link a variable. When a textbox is simply employed to receive a text entered by the user, then it will be enough to call the get() method to obtaint the text when we need it, as previously exposed. The select_present() method returns a boolean that indicates where there is a selection at all. You can use the icursor method to change this from the program. Running python -m tkinter from the command line should open a window demonstrating a simple Tk interface, letting you know that tkinter is properly installed on your system, and also showing what version of Tcl/Tk is installed, so you can read the Tcl/Tk documentation specific to that version. invoke () Configuration Options: command, default, takefocus, text, textvariable, underline, width, image, compound, padding, state, cursor, style, class tkinter.ttk. INSERT (or insert) corresponds to the current position of the text cursor. You can rate examples to help us improve the quality of examples. from tkinter import Step 2: Now, create a GUI app using tkinter. height Specifies a desired height that the canvas widget should request from its geometry manager. If an empty string is given, the widget should defer to its parent for cursor specification. Button ( text = "Get selection", command = get_selection ) Button (masterNone, kw) Ttk Button widget, displays a textual label and/or image, and evaluates a command when pressed. These are the top rated real world Python examples of extracted from open source projects. Step 1: First, import the library tkinter. cursor Specifies the mouse cursor to be used for the widget. # Get the selection start and end indexesīutton = ttk.
