I have tried this right now and it works, supposing you have a file named tick.png in the same folder as this script.

import sys
from PyQt4 import QtGui, QtCore
from PyQt4.QtGui import QApplication, QDialog, QListWidgetItem, QListWidget, QIcon

def main():

    app = QtGui.QApplication(sys.argv)
    window = QDialog()

    list = QListWidget( window )

    itm = QListWidgetItem( "Tick" );
    itm.setIcon(QIcon(r"tick.png"));
    list.addItem(itm);

    window.show( )
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()

The chat-like-icon system may be different from this, but right now I don't see a way to have a QListWidgetItem with multiple smileys and text.

You may think of smileys as a particular case of a QListWidgetItem where the text is blank and only the icon is present.

Another solution is using a read-only QTextEdit as chatboard and have the user typing its text + icon + text (etc.) in a separate editable QTextEdit. Then, when he presses the send button, append everything he typed to the read-only QTextEdit.

import sys
from PyQt4 import QtGui, QtCore
from PyQt4.QtGui import QApplication, QDialog, QListWidgetItem, QListWidget, QIcon, QTextEdit, QTextDocumentFragment

def main():

    app = QtGui.QApplication(sys.argv)
    window = QDialog()

    list = QListWidget( window )

    textEditor = QTextEdit( window );
    textEditor.setReadOnly( True )
    tick_icon = QTextDocumentFragment.fromHtml(r"<img src='tick.png'>");

    textEditor.insertPlainText ( " ValiumKnight writes: " )
    textEditor.textCursor().insertFragment(tick_icon);
    textEditor.insertPlainText ( " Hello World " )
    textEditor.textCursor().insertFragment(tick_icon);
    textEditor.textCursor().insertFragment(tick_icon);
    textEditor.textCursor().insertFragment(tick_icon);

    window.show( )
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()

Bye!
