PYGLET - On Insert Text Event Formatted Document

PYGLET - On Insert Text Event Formatted Document

In Pyglet, you can handle events for text input and other window-related actions by utilizing its event framework. To capture and respond to text insertion events in a formatted document, you can use the on_text event provided by Pyglet's window class.

Here's a simple example demonstrating how to capture text insertion events using Pyglet and then rendering a formatted document:

  • Setup

First, you need to install pyglet:

pip install pyglet 
  • Sample Code

The following is a basic Pyglet application that responds to the on_text event:

import pyglet from pyglet.window import key window = pyglet.window.Window() label = pyglet.text.Label('', font_size=36, x=10, y=window.height // 2, anchor_y='center') # The formatted document (a simple string in this example) document = '' @window.event def on_draw(): window.clear() label.draw() @window.event def on_text(text): global document # For demonstration purposes, we'll just append the inserted text to our "document" # You can format or process the text as needed document += text # Update the label to show the document content label.text = document @window.event def on_key_press(symbol, modifiers): if symbol == key.BACKSPACE and document: # Handle backspace to remove the last character document = document[:-1] label.text = document elif symbol == key.ENTER: # Handle enter key to add a new line document += '\n' label.text = document pyglet.app.run() 

In this example:

  • We create a window and a label to display the text.
  • The on_text event captures text input and appends it to a "document" (in this simple case, a string).
  • We've also added basic handling for the backspace and enter keys to demonstrate more functionality.
  • The content of the document is displayed in the window using a label.

You can expand this example to handle more advanced formatting and richer document structures based on your requirements.
