How to display image on QPlainTextEdit

[naoyamakino]

Hi there, I am looking for a way to display image(emoticons) on QPlainTextEdit.
here is what I have done so far; this class is called by a QWidget class

import sys
from PyQt4 import QtGui
from PyQt4 import QtCore
 
class TextView(QtGui.QPlainTextEdit):
    def __init__(self,Ui_MainWindow, parent=None):
        QtGui.QPlainTextEdit.__init__(self, parent)
        self.setReadOnly(True)
 
        cursor = self.textCursor()
        cursor.movePosition(QtGui.QTextCursor.NextWord, QtGui.QTextCursor.KeepAnchor)
        cursor.insertText("test")
 
        self.setTextCursor(cursor)
 
        imageCursor = self.textCursor()
        imageCursor.movePosition(QtGui.QTextCursor.NextWord, QtGui.QTextCursor.KeepAnchor)
 
        icon = QtGui.QPixmap("image/emoticon.png")
        image = icon.toImage()
        if image.isNull():
            print 'null'
        imageCursor.insertImage(image)
        self.setTextCursor(imageCursor)

import sys
from PyQt4 import QtGui
from PyQt4 import QtCore

class TextView(QtGui.QPlainTextEdit):
    def __init__(self,Ui_MainWindow, parent=None):
        QtGui.QPlainTextEdit.__init__(self, parent)
        self.setReadOnly(True)
        
        cursor = self.textCursor()
        cursor.movePosition(QtGui.QTextCursor.NextWord, QtGui.QTextCursor.KeepAnchor)
        cursor.insertText("test")
        
        self.setTextCursor(cursor)

        imageCursor = self.textCursor()
        imageCursor.movePosition(QtGui.QTextCursor.NextWord, QtGui.QTextCursor.KeepAnchor)

        icon = QtGui.QPixmap("image/emoticon.png")
        image = icon.toImage()
        if image.isNull():
            print 'null'
        imageCursor.insertImage(image)
        self.setTextCursor(imageCursor)

To copy to clipboard, switch view to plain text mode 

now it only displays "text" but not the image. What am I doing wrong? is there any ways to display image or icon onto QPlainTextEdit?

I would appreciate advice if anyone has encountered this or a similar issue.

You can't do that... that's why it's called plaintext edit. Use QTextEdit or QTextBrowser instead.

thank you for your reply, wysota. yes that works!!
here is my code for anyone who had a similar problem.

class TextView(QtGui.QTextEdit):
    def __init__(self,Ui_MainWindow, parent=None):
        QtGui.QTextEdit.__init__(self, parent)
        self.setReadOnly(True)
        self.setAcceptRichText(True)
    def insert(self, string,emoticonList):
        cursor = self.textCursor()
        if not emoticonList:
            cursor.insertText(string)
        else:
            ls = shlex.split(str(string))
            for word in ls:
                for emoticon in emoticonList[:]: 
                    if word == emoticon:
                        path = "image/emoticons/" + word
                        icon = QtGui.QPixmap(path)
                        image = icon.toImage()
                        cursor.insertImage(image)
                    else:
                        cursor.insertText(word + " ")
        self.setTextCursor(cursor)
        end = "<br>"
        fragment = QtGui.QTextDocumentFragment.fromHtml(end)
        self.textCursor().insertFragment(fragment)
    def insertReceiveMessage(self, msg):
        cursor = self.textCursor()
        cursor.insertText(msg)
        self.setTextCursor(cursor)
        end = "<br>"
        fragment = QtGui.QTextDocumentFragment.fromHtml(end)
        self.textCursor().insertFragment(fragment)

class TextView(QtGui.QTextEdit):
    def __init__(self,Ui_MainWindow, parent=None):
        QtGui.QTextEdit.__init__(self, parent)
        self.setReadOnly(True)
        self.setAcceptRichText(True)
    def insert(self, string,emoticonList):
        cursor = self.textCursor()
        if not emoticonList:
            cursor.insertText(string)
        else:
            ls = shlex.split(str(string))
            for word in ls:
                for emoticon in emoticonList[:]: 
                    if word == emoticon:
                        path = "image/emoticons/" + word
                        icon = QtGui.QPixmap(path)
                        image = icon.toImage()
                        cursor.insertImage(image)
                    else:
                        cursor.insertText(word + " ")
        self.setTextCursor(cursor)
        end = "<br>"
        fragment = QtGui.QTextDocumentFragment.fromHtml(end)
        self.textCursor().insertFragment(fragment)
    def insertReceiveMessage(self, msg):
        cursor = self.textCursor()
        cursor.insertText(msg)
        self.setTextCursor(cursor)
        end = "<br>"
        fragment = QtGui.QTextDocumentFragment.fromHtml(end)
        self.textCursor().insertFragment(fragment)
