PYGLET - Getting Position From Point in Incremental Text Layout

PYGLET - Getting Position From Point in Incremental Text Layout

In pyglet, if you want to determine the position (i.e., the x, y coordinates) from a specific point (i.e., an index) within the text of an IncrementalTextLayout, you can use the caret attribute of the layout, which provides the current caret position.

Here's a step-by-step guide:

  1. Create a Caret object associated with the IncrementalTextLayout.
  2. Set the position of the caret to the desired index using the set_position() method.
  3. Retrieve the x and y coordinates of the caret.

Here's an example:

import pyglet from pyglet.text import IncrementalTextLayout, Caret, Label from pyglet.text.document import FormattedDocument window = pyglet.window.Window(500, 500) # Create a document and layout document = FormattedDocument("Hello\nPyglet\nWorld!") layout = IncrementalTextLayout(document, 300, 300, multiline=True) layout.x = 50 layout.y = 300 # Create a Caret object associated with the layout caret = Caret(layout) # Set the position of the caret to a specific index (e.g., 10) caret.set_position(10) # Get the x, y coordinates of the caret x, y = caret.x, caret.y print(f"Position for point (index 10) in text: x={x}, y={y}") @window.event def on_draw(): window.clear() layout.draw() caret.draw() pyglet.app.run()

In this example, the Caret object is used to determine the x and y coordinates for the point at index 10 in the text of the IncrementalTextLayout. Adjust the index in the set_position() method to get the position for different points within the text.
