Disable mouse wheel scroll on QscrollArea

[Nedo Bianchi]

Hi, I would like to simply disable mouse wheel scroll on QScrollArea, in order to scroll down only by clicking on right scrollbar, but I can't find any solution on the Internet.

app = QtGui.QApplication([])
sa = pg.QtGui.QScrollArea()
screen_resolution = app.desktop().screenGeometry()
scwidth, scheight = screen_resolution.width(), screen_resolution.height()

win = pg.GraphicsWindow()
win.setFixedHeight((scheight*1740)/1080)
win.setFixedWidth(scwidth-20)
win.addViewBox()
sa.setWindowTitle("Meteo Station Graph")
sa.setWidget(win)
sa.showMaximized()
pg.setConfigOptions(antialias=True)

The problem is that I have a lot of graphs in my scroll area, and when I try to mousewheel on one of them, the page will scroll up or down together with the graph.

Thank you in advance if you can help me with this problem.

I just managed to resolve the Issue creating a class:

class Scroller(pg.QtGui.QScrollArea):

    def __init__(self):
        pg.QtGui.QScrollArea.__init__(self)

    def wheelEvent(self, ev):
        if ev.type() == QtCore.QEvent.Wheel:
            ev.ignore()

app = QtGui.QApplication([])
sa = Scroller()

screen_resolution = app.desktop().screenGeometry()
scwidth, scheight = screen_resolution.width(), screen_resolution.height()

win = pg.GraphicsWindow()
win.setFixedHeight((scheight*1740)/1080)
win.setFixedWidth(scwidth-20)

sa.setWindowTitle("Meteo Station Graph")
sa.setWidget(win)
sa.showMaximized()
pg.setConfigOptions(antialias=True)

 I dunnò if this is the most correct way, but I think it's really simple
