[SOLVED] PyQt button with an image on it

jazzycamel · wrote on 22 May 2013, 13:03

My apologies, try the following:

@
self.button.setIcon(QtGui.QIcon(''c:/Itllworkthistime/z.jpeg''))
self.button.setIconSize(QtCore.QSize(24,24)
@

Assuming you have:

@
from PyQt4 import QtGui, QtCore
@

Hope this helps ;o)

I do have
[code] from PyQt4 import QtGui, QtCore [/code]
It says it's invalid syntax then highlights the "c" from c:/Itllworkthistime/z.jpeg
Then if I take the double apostrophes out to highlight it in green, it comes up with the same error and highlights the "self" from
[code] self.button.clicked.connect(self.handleButton) [/code]

My bad (typo), the path should just be a normal python string i.e. "c:/Itllworkthistime/z.jpeg".

It's still highlighting the "self" in red, which is really weird, because it wasn't before :S

Missing bracket:
@
self.button.setIconSize(QtCore.QSize(24,24))
@

And if I take out
[code] self.button.clicked.connect(self.handleButton) [/code]
it says that layout in the line below it is invalid syntax :S

Ahhh c:
Now I'm getting a new error when I run it:
[code]
Traceback (most recent call last):
File "C:\Itllworkthistime\email button.py", line 32, in <module>
window = Window()
File "C:\Itllworkthistime\email button.py", line 10, in init

AttributeError: 'Window' object has no attribute 'button'
[/code]

We're making quite heavy weather of this! The following works fine on my system (with a different image file obviously):

@
from PyQt4 import QtGui, QtCore

import smtplib

from email.mime.text import MIMEText

class Window(QtGui.QWidget):
def init(self):
QtGui.QWidget.init(self)
self.button = QtGui.QPushButton('', self)
self.button.clicked.connect(self.handleButton)
self.button.setIcon(QtGui.QIcon("c:/Itllworkthistime/z.jpeg"))
self.button.setIconSize(QtCore.QSize(24,24))
layout = QtGui.QVBoxLayout(self)
layout.addWidget(self.button)

def handleButton(self):
    fp = open('Firetruck.txt', 'r')
    msg = MIMEText(fp.read())
    fp.close()

    msg['Subject'] = 'Subject'
    msg['From'] = 'ajames@brecon-hs.powys.sch.uk'
    msg['To'] = 'swilliams@brecon-hs.powys.sch.uk'

    s = smtplib.SMTP('BHS-MAIL')
    s.send_message(msg)

if name == 'main':

import sys
app = QtGui.QApplication(sys.argv)
window = Window()
window.show()
sys.exit(app.exec_())

Ah :L
I accidentally deleted the line
[code]
self.button = QtGui.QPushButton('', self)
[/code]
It's working now, but the image isn't there :c

Check the name of and the path to the image is correct. If its in the same folder as your python script just use a relative path:

@
...
self.button.setIcon(QtGui.QIcon("./z.jpeg"))
...
@

It was a .jpg rather than a .jpeg apparently =]
Thank you so much ^_^

If you can help me some more though I'd appreciate it because I've just been told to add a sound for when the button gets clicked, how do I do that? =]
And I've got this extended version of the email script that I half pinched from a tutorial and half wrote myself that sends a gif with html, but I can't seem to get it working:

[code]
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage

me = "swilliams@brecon-hs.powys.sch.uk"
you = "ajames@brecobn-hs.powys.sch.uk"

msg = MIMEMultipart('related')
msg['Subject'] = 'Test Message'
msg['From'] = me
msg['To'] = you
msg.preamble = 'This is a super cool multipart message using html and python c:'

msgAlt = MIMEMultipart('alternative')
msg.attach(msgAlt)

msgTxt = MIMEText('You see this if it fails')
msgAlt.attach(msgTxt)

thehtmlcode = """
<html>
<head>Test Header</head>
<body>
<p>This isn't plain text!<br>
If you're seeing this everything should be working as planned :D<br>
Here's the gif <a href="http://tinypic.com?ref=2wpnfnt" target="_blank"><img src="http://i43.tinypic.com/2wpnfnt.gif" border="0" alt="Image and video hosting by TinyPic"></a>
</p>
</body>
</html>
"""
msgTxt = MIMEText(thehtmlcode, msgAlt.attach(msgTxt))

fp = open('coffee.gif', 'r')
msgImg = MIMEImage(fp.read())
fp.close()

msgImg.add_header('EMEGRENCY thing', '<Itsapicture>')
msg.attach(msgImg)

smtp = smtplib.SMTP('BHS-MAIL')
s.send_message(msg)
[/code]

When I run it I get this error message

[code]
Traceback (most recent call last):
File "C:\Users\ACERREVO\Desktop\New folder\Awesomegifworksscript.py", line 36, in <module>
msgImg = MIMEImage(fp.read()) #something's wrong here.

The "#something's wrong here." in the error message I put in then took out to post, because I wanted to remind myself that it was the line referred to in the error message =]

The following example plays a sound when the button is pressed:

@
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from PyQt4.phonon import Phonon

class Widget(QWidget):
def init(self, parent=None, **kwargs):
QWidget.init(self, parent, **kwargs)

    l=QVBoxLayout(self)
    l.addWidget(QPushButton("Play", self, clicked=self.play))

def play(self):
    self.output=Phonon.AudioOutput(Phonon.MusicCategory)
    self.media=Phonon.MediaObject()
    Phonon.createPath(self.media, self.output)
    self.media.setCurrentSource(Phonon.MediaSource('./sound_file.wav'))
    self.media.play()

if name=="main":
from sys import argv, exit

a=QApplication(argv)
w=Widget()
w.show()
w.raise_()
exit(a.exec_())

@

You'll need the Phonon module installed for this to work (and provide your own sound file ;o).

For your other problem, try the following for line 34:

@
fp = open('coffee.gif', 'rb')
@

This opens the file in binary rather than ASCII mode.

Also, if your original problem is solved, please insert [SOLVED] into the threads title to mark it as such.

swilliams2 · wrote on 22 May 2013, 14:46

I've changed that, it's working now :D
Only it's sending the plain text alternative instead of the html =/

And thank you for the sound script, I'll have a play around with it now :D
Where would I get Phonon from though? =]
