In this article we will see how we can trigger the on delete text event 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). Formatted documents are generally laid out to enhance their human readability by adding structure, such as headings, indentation, font variations, and other devices that transform plain (unformatted) text so that they have an appearance similar to published works. This event get triggered when user delete text. The event handler is bound by the text layout; there is no need for applications to interact with this method.
We can create a window and formatted document with the help of commands given below
# creating a window window = pyglet.window.Window(width, height, title) # creating document documnet = pyglet.text.document.FormattedDocument(text)
Below is the syntax of the on delete text event
# on delete text event
def on_delete_text(start, end):
Below is the implementation
