I was able to darken the image within the paint event, but can't get it to
work inside the enterEvent.
from PySide2 import QtWidgets
from PySide2 import QtGui
from PySide2 import QtCore
class PicButton(QtWidgets.QAbstractButton):
def __init__(self, pixmap, parent=None):
super(PicButton, self).__init__(parent)
self.pixmap = pixmap
def paintEvent(self, event):
painter = QtGui.QPainter(self)
painter.drawPixmap(event.rect(), self.pixmap)
#painter.setCompositionMode(QtGui.QPainter.CompositionMode_DestinationIn)
painter.fillRect(event.rect(), QtGui.QBrush(QtGui.QColor
(0,0,0,128)))
def enterEvent(self, event):
print('hovering')
def sizeHint(self):
return self.pixmap.size()
window_wid = QtWidgets.QWidget()
vlayout_wid = QtWidgets.QVBoxLayout()
myPixmap = QtGui.QPixmap("D:\DOWNLOADS\GSG Assets S22-R25\GSG
Assets\HDRIS\Hdris 1\Commercial
Locations\PlusThumbnails\Concrete_Office_Outside.jpg")
my_button = PicButton(myPixmap)
my_button.setCursor(QtGui.QCursor(QtCore.Qt.PointingHandCursor))
my_button.setMaximumSize(200,100)
vlayout_wid.addWidget(my_button)
window_wid.setLayout(vlayout_wid)
window_wid.show()
