How to detect if mouse is holding the scroll bar QPlainTextEdit

[mirswith]

Is there a way to detect if the mouse is holding onto a scroll bar within the QPlainTextEdit control? I am using QPlainTextEdit as a log viewer and while messages are being spit out I keep the view scrolled to keep the new text in view, this is working great however I would like to let the user override this auto scrolling if they are hanging onto the scroll bar.

I have tried subclassing QPlainTextEdit and overridding the mousePress/ReleaseEvent's however these never get called and I do not see any obvious signals that would help notify me when the user has grabbed/released the scroll bar.

Any ideas?

Thanks.

Don't scroll down automatically unless the view is already scrolled down?

That's a great idea and is working wonderfully.

I opted for this approach in the end, however I did manage to get it working the other way as well, silly me did not notice the isSliderDown() call for QScrollBar's. One caveat to your approach is that I had to set a flag to determine if this was the first time I am appending text in which case I move the scroll bar to the maximum position.

Thanks!
