"""
This script creates a GUI message dialog using PyQt5. It allows the user to specify
the type of message, title, and content, as well as customize the icon and position of the dialog.

Usage:
/usr/libexec/msgcollector/msgdispatcher_dispatch_x <message_type> <title> <message> <position> [icon]

Arguments:
1. message_type: 'info', 'warning', or 'error'
2. title: The window title
3. message: The main message text
4. position: The position of the dialog (e.g., "1" for top-left corner)
5. icon (optional): Path to a custom icon (defaults to a specific icon if not provided)

Example:
/usr/libexec/msgcollector/msgdispatcher_dispatch_x warning "Warning Title" "This is a warning message." "1" "/path/to/custom/icon.svg"
