Hello,

Suppose that I have a GtkScrolledWindow witch has a child of class
GtkIconView, the icons are disposed horizontally, then, only an
horizontal scroll bar is showed when there are many icons.

That I want is to allow that the GtkIconView scroll horizontally with
the mouse wheel. I can capture the event but I don't know how scroll the
GtkIconView.

Is there a way to scroll programmatically the GtkIconView the same
amount as when I press the arrow button in the scroll bar?

I know the existence of "gtk_icon_view_scroll_to_path" but I want to
scroll the GtkIconView an amount of pixels, not necessarily to a
specific path.

Thanks in advance!
Regards!

I don't think you have to go to that much trouble.
If you hover the cursor over the horizontal scrollbar then using the wheel should scroll it back and forth. The principle even works on my trackpad.
I think you should even be able to scroll it when not hovered if you give focus to the scrollbar. As to programmatic movement the amount a scrollbar is moved by is controlled by the gtk_adjustment it inherits.
