PYGLET – Moving Caret to nearest point
In this article we will see how we can move caret to nearest point in PYGLET module in python. Pyglet is easy to use but powerful library for developing visually rich GUI applications like games, multimedia etc. A window is a “heavyweight” object occupying operating system resources. Windows may appear as floating regions or can be set to fill an entire screen (fullscreen). Caret is basically visible text insertion marker for pyglet.text.layout.IncrementalTextLayout. The caret is drawn as a single vertical bar at the document position on a text layout object. If mark is not None, it gives the unmoving end of the current text selection. Moving caret means to move the editable mark.
We can create a window and caret with the help of commands given below
# creating a window window = pyglet.window.Window(width, height, title) # creating a caret caret = pyglet.text.caret.Caret(layout, color=(255, 255, 255))
In order to create window we use move_to_point method with the caret object
Syntax : caret.move_to_point(x, y)
Argument : It takes two integer as argument
Return : It returns None
Below is the implementation
Python3
