Writing a routine to allow dragging lower right corner of a thumbnail to resize thumbnails. Need to figure out area hidden behind Scroll Bar(s):

In this example, about half the thumbnail Image is Showing. How much is hidden is the question.

[<--------- ThumbNail Image -------->]
[<--------- ImageenMView] ---------->]

[<---- ?? Area ---->]


Cheers,

John

Hi John

Sorry, I didn't really understand your image. If you are looking for the width of the scrollbar, you can check if it is visible using CurrentScrollBars, and if so its width will be the standard scrollbar width:

If that's not what you mean, perhaps see:

Attached please find a picture of an ImageenMView with 2 thumbnail images (sorry it's a bit confusing). Both thumbnails are partially hidden offscreen on the Y axis. Interested in the length of the Right side of the thumbnails ???

The algorithm would be (assumes ietxCenterThumbnailColumn is not being used):
rightSpace := ImageEnMView.ClientWidth - ImageEnMView.ThumbSizeInfo( itsCell ).X * ImageEnMView.CalcGridWidth();
