[FIXED] pyside - auto scroll down in qscrollarea

Issue

how down the scroll when new data arrives? I want to go down with the new data, but the scroll is kept in the same place. how to lower scroll automatically?

I tried using:

maximumY = self.scroll.verticalScrollBar().maximum()
self.scroll.verticalScrollBar().setValue(maximumY)

but, not work

SOLVED

self.scroll.verticalScrollBar().rangeChanged.connect(self.ResizeScroll)
def ResizeScroll(self, min, maxi):
    self.scroll.verticalScrollBar().setValue(maxi)

Solution

This should be a succinct way to get the behaviour desired - please check.

bar = self.scroll.verticalScrollBar()
bar.rangeChanged.connect( lambda x,y: bar.setValue(y) )

or

bar.rangeChanged.connect( lambda x,y: bar.setValue( 9999 ) )
