Scroll outside of bounds

[Derpalus]

Hello again, more questions!

I'd like to be able to scroll past the bounds of the image. Like if I'm zoomed in so the image is covering the entire screen, there is no way to scroll past the edge of the image.

I can set up so I can zoom out past the edges of the image using setMinimumScaleMode and setScaleLimits, but I still haven't figured out how (if even possible) to override the scrolling?

I'm not quite sure I understand what you mean I should do? Should I fork it? In that case it seems like I should perhaps change the values that getScrollMinX/Y and getScrollLimitX/Y provide.

you can subclass it and override those methods to return different values. e.g., instead of a minimum of 0, you could have a minimum of -1000

Thanks for the help!

NP, let us know how it goes

I have to do the same thing, subclassing is not a problem, but how i should supply modified class to TileView?

I have made a pull request of my solution. Don't know if it's good enough but if mogarius accepts it then you can use it as well without having to make your own changes.

@tkrz As @Derpalus mentioned, he's submitted a PR, which I suspect will be accepted in a few days, but as to your question:

You make a subclass like MyTileView, then use that instead of a normal TileView.
