We are just performing a print operation on function call or on event calling.Examples Documentation Try Discuss GitHub Version 5ĬodeMirror is published as a set of NPM packages under.This function is called when the user double clicks on the option of treeviw widget.In the function definition, we initialized item with identifies property followed by treeview object.Here in the function, we passed the parameter event. Next, we used to bind with double click event and also we have defined a function named callback.Print("Your clicked on ".format(em(item,"text"))) Item=treeview.identify('item',event.x, event.y) In this example, we will see how we can use the bind function for performing a double click operation on the tree view. Please follow the next example for more elaboration.Įxample 2: Advance Example on Tree View widget with click event.Here we have to use the bind function to make it work as a click event. Note: In the tree view, we cannot use the command for the click event.Next, we aligned the items as sub-items as per our requirement.Now we inserted items into our treeview widget using the insert function or method of the tree view widget.In the very next line, we have initialized the tree view object with a Treeview widget with attributes height.Next, we have added a label widget in our application window.Then we have initialized root as an object for Tk() class for creating a root window.First, we have imported all the required libraries and modules of Tkinter using import *.Label = Label(root, text="This is TreeView Widget").pack(side=TOP, pady=10) Let’s see some example to understand this concept better Syntax: treeview = ttk.Treeview(root, height=7).pack() We can remove add or remove nodes/widget dynamically as per the requirement of our GUI application. Tree View Widget: The tree view widget in Tkinter allows us to set up our widgets in a tree-like structure along with their attributes. Using the Tkinter library of python which carries large numbers of widgets, we can easily create a Graphical User Interface for our application. Tkinter is the widely used library for GUI application development. Tree View Widget in Tkinter Python provides a vast number of libraries for GUI application development.
