V.scrollbar scroller/thumb
Posted: Wed Feb 08, 2012 9:30 pm
The vertical scrollbar's scroller/thumb gui component for xnview does not work properly for very large images (i.e. for an image height of 70000). For such a large image, you cannot drag the 'thumb' to quickly scroll down to the bottom of the image (it ends up looping back to the top). This applies to the browser view and full screen view vertical scroll bar's scroller/thumb.
There appears to be some type of overflow related to the gui component.
Interestingly all the other methods to view the entire image work fine, that is these all work fine: the down arrow button component of the scrollbar, clicking in the space between the thumb and the down arrow button, and scrolling manually with the down arrow keys/panning with the mouse in fullscreen.
For very large images, the scroller/thumb is the only viable way to quickly pan/scroll to a part of an image.
(I hope this problem is fixable, as I imagine if the component is part of a closed library, you won't be able to fix it yourself?)
