Hi,

You can implement what you need in the Mouse_Down Event in the GdViewer. Then you have to design a length of formula:
PreviousOnePage: that is the distance between the mouse and the top of the viewer divided by the number of previous pages.
AfterOnePage: the distance between the mouse and the bottom of the viewer divided by the number of pages left.

Upon moving you can basically call the GdPicture Functions DisplayNextPage and DisplayLastPage.

We will not implement such a feature, but you can easily implement it if you follow the above instructions.

Best Regards,
Sami
