How to Return Word Under Cursor In Tkinter?

To return the word under the cursor in tkinter, you can use the Text widget's index method to get the current cursor position. Once you have the cursor position, you can use the get method to retrieve the word at that position. This can be done by finding the start and end positions of the word based on the cursor position.

Here is a simple example of how you can implement this in tkinter:

import tkinter as tk

def get_word_under_cursor(event):
    cursor_index = text.index(tk.CURRENT)
    start = cursor_index
    while text.get(start) not in [' ', '\n', '\t', '', '.', ',', ':', ';']:
        start = text.index('{}-1c'.format(start))
        if start == '1.0':
            break
    start = text.index('{}+1c'.format(start))

    end = cursor_index
    while text.get(end) not in [' ', '\n', '\t', '', '.', ',', ':', ';']:
        end = text.index('{}+1c'.format(end))
        if end == '{}.0'.format(text.index('end')):
            break

    word = text.get(start, end)
    print(word)

root = tk.Tk()

text = tk.Text(root)
text.pack()

text.bind('<Motion>', get_word_under_cursor)

root.mainloop()

What is the difference between word under cursor and word at cursor position in tkinter?

In tkinter, the "word under cursor" refers to the word that the mouse pointer is currently hovering over, while the "word at cursor position" refers to the word that the text cursor is currently located at within a text widget.

The word under cursor can be obtained using the xview and yview methods of the text widget, which return the coordinates of the mouse pointer relative to the text widget. Using these coordinates, we can then use the index method to find the word under the cursor.

On the other hand, the word at cursor position can be obtained using the index("insert") method, which returns the index of the text cursor within the text widget. By using this index, we can extract the word that the text cursor is currently positioned at.

Overall, the main difference between the two concepts is that the "word under cursor" is determined by the mouse pointer, while the "word at cursor position" is determined by the text cursor position within a text widget.

What is the purpose of retrieving word at cursor position in tkinter?

The purpose of retrieving a word at the cursor position in tkinter is to allow the user to interact with and manipulate text in a more user-friendly and efficient manner. By retrieving the word at the cursor position, the application can provide context-specific options, such as spell-checking, auto-complete, or word suggestions. This can help the user to type more accurately and efficiently, as well as provide a smoother user experience.

How to display the word under cursor in tkinter?

To display the word under the cursor in a tkinter application, you can use the following steps:

1. Create a tkinter Label widget to display the word under the cursor.
2. Bind the Label widget to the mouse motion event so that it updates its text whenever the mouse moves.
3. Get the word under the cursor by using the event.x and event.y coordinates and the tkinter Text widget's index method.

Here is an example code snippet to achieve this:

import tkinter as tk

def display_word(event):
    index = text.index(f"@{event.x},{event.y}")
    word = text.get(index + " wordstart", index + " wordend")
    label.config(text=word)

root = tk.Tk()

text = tk.Text(root)
text.pack()

label = tk.Label(root, text="")
label.pack()

text.bind("<Motion>", display_word)

root.mainloop()

In this code, a Text widget is used to input text, and a Label widget is used to display the word under the cursor. The display_word function is bound to the mouse motion event and is responsible for updating the Label text with the word under the cursor. The index method is used to get the word under the cursor based on the mouse position.
