Hello, All !
Here's the text of my program:

base = WIDGET_BASE(XSIZE=650, YSIZE=400)
draw1 = WIDGET_DRAW(base, XSIZE = 550, X_SCROLL_SIZE=200, YSIZE = 550,
Y_SCROLL_SIZE=200, XOFFSET=5, /APP_SCROLL)
WIDGET_CONTROL, /REALIZE, base
WIDGET_CONTROL, draw1, GET_VALUE = index
WSET, index
ImageIsRead=DIALOG_READ_IMAGE(FILE=FileName, FILTER_TYPE='.tif, .tiff', $
IMAGE=PhotoArray)
TVSCL, PhotoArray

The image is successfuly loaded in the viewport but the scrolling does not
work. Does anybody know
how to solve the problem and create the widget where scrolling is possible
in graphic viewport?
I'm using IDL 5.4 for Win32.

Regards, Evgeny Turchin.
