I've seen that a lot of people have this problem and decided to write a proper example on how to fix it. You can find it here: An example on how to make QLabel clickable The solution in my post solves the problem by extending QLabel so that it emits the clicked() signal. The extended QLabel looks something like this:

class ExtendedQLabel(QLabel):

    def __init__(self, parent):
        QLabel.__init__(self, parent)

    def mouseReleaseEvent(self, ev):

I hope this helps!

You can subclass QAbstractButton and make a button of your own. Here is a basic simple example:

import sys
from PyQt4.QtGui import *

class PicButton(QAbstractButton):
    def __init__(self, pixmap, parent=None):
        super(PicButton, self).__init__(parent)
        self.pixmap = pixmap

    def paintEvent(self, event):
        painter = QPainter(self)
        painter.drawPixmap(event.rect(), self.pixmap)

    def sizeHint(self):
        return self.pixmap.size()

app = QApplication(sys.argv)
window = QWidget()
layout = QHBoxLayout(window)

button = PicButton(QPixmap("image.png"))

That's not a super easy way, but it gives you a lot of control. You can add second pixmap and draw it only when the mouse pointer is hover over button. You can change current stretching behavior to the centering one. You can make it to have not a rectangular shape and so on...

Button that changes images on mouse hover and when pressed:

from PyQt4.QtGui import *
from PyQt4.QtCore import *

class PicButton(QAbstractButton):
    def __init__(self, pixmap, pixmap_hover, pixmap_pressed, parent=None):
        super(PicButton, self).__init__(parent)
        self.pixmap = pixmap
        self.pixmap_hover = pixmap_hover
        self.pixmap_pressed = pixmap_pressed


    def paintEvent(self, event):
        pix = self.pixmap_hover if self.underMouse() else self.pixmap
        if self.isDown():
            pix = self.pixmap_pressed

        painter = QPainter(self)
        painter.drawPixmap(event.rect(), pix)

    def enterEvent(self, event):

    def leaveEvent(self, event):

    def sizeHint(self):
        return QSize(200, 200)
