Hello,
one of IDL programmers is trying to access information about the
horizontal scroll bar of a widget list. He has a title for different
text columns within the list, and wishes to be able to scroll the titles
for these column when he scrolls left or right. Is there a way to get
the index or the scroll bar, and or get events for left-right moves.
Yes, I realize this is in most cases way outside of the functionality of
a widget_list, but a title (label) that would move with the data is
reasonable important.
Also, various work arounds discovered some other interesting wuestions.
In a widget_slider, is there a way to specify the 'step distance'. That
is the number of values that the slider jumps over when you click on the
slider, either above or below the slider button. It seems to be some
number that is dependent on the min and max value and possible the
number of pixels the slider occupies (in the direction of the slider;
vertical or horizontal). We are looking for being able to set it to
jump say x, where our X might represent 24 (a page height). If this is
possible, please let me know. (we still want to be able to move
by grabing the slide button)
