TextInput widget's copy-paste fails silently

[maqp]

Problem:

On Ubuntu 24.04 LTS that defaults to Wayland, trying to paste to TextInput widget fails silently on line 1293.

The reason for this was that as per Pyperclip, one of the packets in xclip, xsel, or wl-clipboard was missing. Of these at least wl-clipboard works, I didn't test others.

Solution:

Perhaps the library could try to detect the platform and either print a warning, or raise an exception when this happens. E.g.

# Paste text in cursor
try:
    text = paste()
except PyperclipException:
    import os
    if os.getenv("XDG_SESSION_TYPE") == 'wayland':
        raise PyperclipException("Pasting from clipboard failed. Please install package 'wl-clipboard'")
    return False

Hi @maqp. I added two warnings if copy/paste fails.

pygame-menu/pygame_menu/widgets/widget/textinput.py

Lines 64 to 79 in 0f996e2

	def clipboard_warn(e: PyperclipException, op: str) -> None:
	"""
	Generates a warning message if clipboard failed.
	:param e: Exception
	:param op: Operation that failed
	"""
	paste_warn: str = f'{op} from clipboard failed ({e}). '
	if os.getenv('XDG_SESSION_TYPE') == 'wayland':
	paste_warn += 'Please install package "wl-clipboard"'
	elif platform.system() == 'Linux':
	paste_warn += 'On Linux, install "xclip" or "xsel"'
	else:
	paste_warn += (f'An unrecognized error happened. '
	f'Please create a new issue on {pygame_menu.__url_bug_tracker__}')
	warn(paste_warn)

Let me know if that addresses the enh, so you can close this issue. Thanks!
