Chatz-UI

A simple, python, PyQt4 chat user interface with emoji support

Chatz Screenshot

Dependencies

  1. Python 2.7
  2. emoji
  3. PyQt4

Running

It's as simple as running main.py with the dependencies installed.

Development

When connecting back-end code, make use of the methods (in main.py - UIHandler class):

  1. refresh_users(users) - to refresh the list of participants shown. It takes a dict argument with the following structure:

    users = {username: [user_id, access_level, last-seen_time], ...}

    access_level: 1 = admin, 2 = moderator, 3 = regular user

  2. display_error(text) - to display errors. It takes a str argument with the error text

  3. sendslot() - to send a typed in message in the text_input widget when the send button has been clicked

  4. recvslot(type_, mesg) - to display received messages. It takes an int argument(type_) to determine what kind of message has been received so as to render it correctly, as well as a tuple argument(mesg) containing the message and details:

    mesg = (sender, message, time_sent)

    type_: 1 = message from server, 2 = message from group, 3 = direct message

Tips

This is front-end code meant to be connected to the chat back-end. When doing this, make use of PyQt slots and signals to prevent freezing of the UI.
