I'm setting up a new desktop widget to make my life easier at work and using QPropertyAnimation to make it pretty. Fading the app in and out doesn't seem to want to work and in typical coder fashion, it's brought my progress to a standstill.
I'm implementing QPropertyAnimation in a personalised class to make my life easier, but since it's not intially worked I've taken it back to the class code and it's still being pretty stubborn. So far I've tried.
class widget(QWidget):
def init(self):
self.setSize(QSize(300, 300))
self.setWindowOpacity(1)
self.setWindowFlags(Qt.FramelessWindowHint | Qt.WindowStaysOnTopHint)
self.setAttribute(Qt.WA_TranslucentBackground)
def paintEvent(self, event):
s = self.size()
qp = QPainter()
qp.begin(self)
qp.setRenderHint(QPainter.Antialiasing, True)
qp.setBrush(QColor().fromRgb(2,106,194))
qp.setPen(QColor().fromRgb(2,106,194))
qp.drawRoundRect(QRect(0,0, 300, 300), 16, 8)
qp.end()
def show(self):
self.superShow()
a = QPropertyAnimation(self, "windowOpacity")
a.setDuration(500)
a.setStartValue(1)
a.setEndValue(0)
a.start()
def hide(self):
a = QPropertyAnimation(self, "windowOpacity")
a.setDuration(500)
a.setStartValue(0)
a.setEndValue(1)
a.finished.connect(self.superHide)
a.start()
def superShow(self):
super(widget, self).show()
def superHide(self):
super(widget, self).hide()
No error messages at all it just hides and shows after the animation duration is over. No idea where to look or what to do to get it working. I've only been coding for like 3 months or so.
Your code has many errors, for example:
Instead of changing the opacity directly I will use QGraphicsOpacityEffect, instead of using the show and close method, I will use the showEvent, hideEvent and closeEvent methods.
